FAQ


About KINS SUPPLEMENT

When should I take the supplements?

There is no specific timing required for taking the supplements.
You can take them anytime that suits your lifestyle.

To help you maintain your daily bacteria care routine, we recommend finding a consistent time—such as “2 capsules before bed”—to make it easier to remember.

Please note that the recommended daily dosage may vary by product, so be sure to check the product packaging for details.

How should I store the supplements?

Avoid direct sunlight and high humidity; store in a cool, dark place.
Refrigeration is not recommended due to potential condensation and temperature fluctuations that may degrade the ingredients.

Are there any medications or foods that should not be taken together with the supplements?

As these are food products, there are generally no concerns.
However, depending on the type of medication you are taking, some combinations may require caution.
It is recommended to space out the intake of fat-soluble vitamins (A, D, E, K), iron, diabetes medications, and heart medications by about 2 hours.
Please consult your physician before consuming if you have concerns about interactions.

Do the bacteria in the supplements reach the intestines alive?

KINS supplements are made with enteric-coated capsules designed to dissolve in the intestines rather than the stomach.
This allows the bacteria to reach the intestines without being destroyed by stomach acid.
Depending on the type, our products contain both live and inactive bacteria.
Even inactive bacteria can serve as nourishment or have beneficial effects on the body.

What are the capsules made of?

The capsules are made of HPMC (Hydroxypropyl Methylcellulose), a plant-based and non-caloric material.
This helps protect bacteria from stomach acid and ensures they reach the intestines alive.
Since they are gelatin-free, they are also suitable for people with pork allergies.

What is the shelf life?

The expiration date is printed on both the package and the refill pouch.
After opening, avoid direct sunlight, store in a cool and dark place, and consume as soon as possible.

What is the size of the supplements?

Each capsule is about 1.8 cm long, which is relatively small and easy to swallow.

I'm concerned about the smell of the ORIGINAL supplement. Is it safe to consume?

The ORIGINAL supplement contains a characteristic smell due to the yeast it includes.
Please rest assured that there are no issues with quality or safety.

Can I take more than the recommended daily amount?Can I decide the dosage myself?

It is advisable to adhere to the recommended daily intake for continuous consumption.
For SKIN+ and GUT+, take 1 capsule per day.
Excessive intake may cause symptoms like loose stools or bloating.
If you have any concerns, please consult with a healthcare professional.

I am lactose intolerant. Can I take the supplements?

ORIGINAL and GUT+ contain trace amounts of lactose.
While some individuals with lactose intolerance can tolerate small amounts, sensitivity varies.
Please consult your physician if you have concerns.

I have a milk allergy. Can I take the supplements?

KINS supplements use culture media containing milk or milk-derived ingredients.
If you have a milk allergy, please consult your physician before consumption.

I have a soy allergy. Can I take the supplements?

The supplements may contain trace amounts of soy-derived ingredients due to the use of soy milk in the cultivation process.
If you have a soy allergy, please refrain from consuming the supplements.
Additionally, the manufacturing facility processes products containing eggs, milk, wheat, peanuts, shrimp, crab, and buckwheat.
Please consult your physician if you have concerns about food allergies.

I am currently undergoing medical treatment. Can I take the supplements?

As these are food products, they can generally be consumed.
However, please consult your physician as there may be considerations based on your treatment.

Generally, the supplements can be taken during pregnancy or while breastfeeding.
However, please consult your physician before use.

About KINS BOOSTER

How should I use the BOOSTER? How much should I apply?

After cleansing, take 2–3 pumps of the BOOSTER and gently apply it to your entire face. Adjust the amount based on your skin condition and preference.

Can the BOOSTER be customized?

Yes. You can choose from different types to suit your skin condition, such as "MOIST" for hydration.

What are the full ingredients in ORIGINAL and MOIST?

Ingredients of ORIGINAL:
Water, Lactobacillus/Soy Milk Ferment Filtrate, Lemon Fruit Water, Butylene Glycol, Rice Ferment Filtrate, Rice Bran Extract, Saccharomyces Cerevisiae Extract, Gaultheria Procumbens (Wintergreen) Leaf Extract, Grapefruit Seed Extract, Hydroxypropyl Methylcellulose, Sodium Citrate, Glycerin

Ingredients of MOIST:
Water, Lactobacillus/Soy Milk Ferment Filtrate, Lemon Fruit Water, Butylene Glycol, Glycerin, Propanediol, Rice Ferment Filtrate, Rice Bran Extract, Saccharomyces Cerevisiae Extract, Gaultheria Procumbens (Wintergreen) Leaf Extract, Grapefruit Seed Extract, Hydroxypropyl Methylcellulose, Hydroxyethylcellulose, PEG/PPG/Polybutylene Glycol-8/5/3 Glycerin, Sodium Citrate, Polyquaternium-51

These formulas also include beneficial microorganisms such as yeasts and koji fungi, as well as ingredients to maintain a mildly acidic pH.

Recommended for:

  • ORIGINAL: Normal to combination skin
  • MOIST: For those concerned about dryness – enriched with moisturizing ingredients like diglycerin
Free from:
  • Surfactants
  • Parabens
  • Ethanol
  • Synthetic fragrances
  • Colorants

What is the texture, scent, and feel of BOOSTER?

BOOSTER offers the following texture, feel, and scent characteristics:

・Light and watery texture
・Feels refreshing upon application
・Absorbs quickly and smoothly
・Spreads easily across the skin
・Leaves the skin feeling moisturized after use
・Virtually unscented (with a faint, yogurt-like aroma)

What are the benefits of BOOSTER?

BOOSTER is designed with a focus on “beauty bacteria that promote skin hydration” to help you achieve a fresh and radiant complexion.

In skincare, the very first product applied after cleansing plays a crucial role, especially in caring for the stratum corneum (outermost skin layer).

BOOSTER is rich in postbiotics and other bacteria-derived ingredients that provide moisture to the stratum corneum—the natural habitat for skin-friendly bacteria—helping to refine skin texture.

It is completely free of surfactants and preservatives, which are unnecessary for the skin.

We recommend using it as the very first step of your skincare routine after cleansing.

What skincare is recommended after using the BOOSTER?

We recommend following BOOSTER with the KINS SERUM. They’re designed to work in harmony, so using them together is ideal.

For a simpler routine, sealing in moisture with jojoba oil or petroleum jelly is also a great option. These oils contain nutrients that act as food for your skin’s microbiome.

However, if you have oily skin, acne, or other skin concerns, you may want to avoid oils high in oleic acid or glycerin—such as olive oil or camellia oil—as these can feed acne-causing bacteria (like *Cutibacterium acnes*).

If you’re unsure about the products you’re currently using, please feel free to contact us anytime!

Can I use BOOSTER with other skincare products? Can it replace toner?

Yes, you can use your regular skincare products after applying the BOOSTER.

While we recommend using it as a replacement for toner, it’s also perfectly fine to use BOOSTER as a pre-toner—applied before your regular toner.

At KINS, we believe that the very first skincare product applied after cleansing is the most important.

Please use BOOSTER as the first step of your skincare routine right after washing your face.

Is BOOSTER considered a penetration booster (introductory serum)?

Although BOOSTER is named with the intention of being the first product you apply after cleansing, it is not a penetration booster in the traditional sense.
It serves a different role compared to conventional pre-serums.

How long does one bottle of BOOSTER last?

When used as directed—1 pump in the morning and 2 pumps at night—one bottle lasts approximately 30 days.

Is BOOSTER suitable for all skin types?

BOOSTER can be used on dry, sensitive, oily, and combination skin.

It is free from:
・Surfactants
・Parabens
・Ethanol
・Synthetic fragrances
・Colorants

However, compatibility may vary by individual. If you notice any irritation, discontinue use immediately.

Note: BOOSTER contains soy-derived ingredients. Please consult a physician if you have a soy allergy.

Is BOOSTER safe for sensitive skin?

Yes, BOOSTER is gentle enough for sensitive skin and is formulated without surfactants, parabens, ethanol, synthetic fragrances, or colorants.

However, since all skin is different, we recommend performing a patch test on an inconspicuous area (such as the inner arm) before full use.

Note: BOOSTER contains soy-derived ingredients. Please consult your doctor if you have a soy allergy.

Is BOOSTER safe for acne-prone skin?

Yes, BOOSTER (especially the ORIGINAL version) can be used on acne-prone skin.
Although it contains small amounts of oleic acid and glycerin, these are minimized to ensure suitability for oily and acne-prone skin.

The MOIST version contains additional moisturizing ingredients like diglycerin. If you prefer a lighter feel, the ORIGINAL version is recommended.

Acne is often caused by excess sebum, which may be triggered by dryness. Maintaining skin hydration is crucial for balanced skin.

BOOSTER is rich in moisturizing and skin-conditioning ingredients that help retain moisture, refine skin texture, and support the skin’s microbiome.

Note: BOOSTER is not a medicated product and is not designed to treat acne. If irritation occurs, discontinue use immediately.

Can I use BOOSTER if I have a soy allergy?

BOOSTER contains soy-derived ingredients.
If you have a soy allergy, please consult your doctor before use.

Can BOOSTER be used on the scalp or body?

Yes, BOOSTER can be used from scalp to body.
However, avoid applying it to inflamed areas, mucous membranes, open wounds, or intimate areas.

How should BOOSTER be stored?

Store BOOSTER at room temperature away from direct sunlight, high humidity, and extreme temperature changes.

What is the expiration date of BOOSTER?

Unopened BOOSTER has a shelf life of 3 years from the manufacturing date.
If there is no discoloration, separation, or unusual smell, and the product appears the same as when purchased, it can be used safely.
After opening, the product does not degrade immediately, but we recommend using it promptly.
If you are unsure of the manufacturing date, feel free to contact us via our inquiry form.

What should I do if I experience itching or redness after using BOOSTER?

If you experience any skin irritation such as itching or redness, stop using BOOSTER immediately.
Although the formula is designed to be gentle, compatibility can vary by individual.
If you have any concerns, please don’t hesitate to contact us through the inquiry form.


About KINS SERUM

How should I use the SERUM and how much should I apply?

SERUM is free from antibacterial and sterilizing agents.
Preservatives are naturally derived, and surfactants are minimally included for the skin’s microbiome.
Please apply it promptly after washing your face.

How long does one bottle of SERUM last?

One bottle contains 30ml.
Using one drop in the morning and one at night should last approximately 30 days.

What is the main difference between BOOSTER and SERUM?

BOOSTER contains only water-soluble ingredients, while SERUM also includes oil-based ingredients.
SERUM is formulated based on BOOSTER but with added moisturizing ingredients for a richer feel.
BOOSTER provides a refreshing, moisturizing finish.
SERUM offers deeper hydration and a more emollient feel.

How is it recommended to use the SERUM?

Apply SERUM as early as possible after washing your face.
If you use BOOSTER, apply SERUM right after.
Otherwise, use it before toner in both the morning and evening.
Use one drop (approx. size of a 5-yen coin) and gently apply it to your skin.
Free of parabens and synthetic colorants.
Formulated with minimal surfactants for a gentle feel.

Is SERUM considered a beauty serum?

SERUM is designed as a beauty serum, but it also contains jojoba oil, making it suitable as a final sealing step.
If you feel it’s not enough, you can follow up with Vaseline or other oils for added moisture.

What kind of skincare is recommended after applying SERUM?

While SERUM is formulated as a beauty serum, its inclusion of jojoba oil allows it to act as a final sealing step.
If additional hydration is desired, applying Vaseline or oil after SERUM is also recommended.

When should I use the SERUM if I also use the BOOSTER?

It is recommended to use the SERUM as early as possible after cleansing.
If you have the BOOSTER, apply the SERUM right after the BOOSTER.
If you don’t have the BOOSTER, use the SERUM before applying your toner, both morning and evening.
Gently pat one drop into your skin.

Is SERUM suitable for all skin types?

Yes, SERUM can be used for dry, sensitive, oily, and combination skin types.
It is free from parabens, ethanol, synthetic fragrances, and artificial colorants.
Although it contains emulsifiers to blend oil-based ingredients, these are carefully selected to support your skin’s microbiome.
Please note that individual compatibility may vary. If you experience any irritation, stop using the product.
SERUM contains soy-derived ingredients, so consult your doctor if you have a soy allergy.

Is SERUM suitable for sensitive skin?

Yes, SERUM is suitable for sensitive skin.
It is formulated with gentle care, being free from:
- Parabens
- Ethanol
- Synthetic fragrances
- Artificial colorants

The REPAIR version contains plant-derived bakuchiol (a skin-conditioning ingredient) and microbiome-friendly components, and has passed human patch tests confirming its low irritation potential.

However, as not all products suit everyone, we recommend a patch test on an inconspicuous area such as the inner arm before use.
SERUM contains soy-derived ingredients, so please consult a doctor if you have a soy allergy.

Can SERUM be used on acne-prone skin?

Yes, SERUM can be used on acne-prone skin.
It is formulated with minimal amounts of oleic acid and glycerin—known as acne bacteria triggers—making it suitable for oily and acne-prone skin.

Acne is often caused by excessive sebum production, which can result from underlying dryness.
Skin-friendly bacteria are essential for preventing dryness and maintaining moisture.

SERUM is designed with this in mind, helping your skin stay hydrated and balanced.

However, please note that SERUM does not contain medicinal ingredients specifically for acne treatment.
If irritation occurs, discontinue use immediately.

Is it safe to use SERUM if I am concerned about glycerin for oily or acne-prone skin?

The glycerin listed at the end of the ingredients list is included in minimal amounts not for its moisturizing properties, but because it is necessary to blend other components.
It is not added for hydration purposes.

Additionally, diglycerin—though similar to glycerin—is not considered a nutrient source for acne-causing bacteria.

However, everyone's skin is different. If you feel that SERUM does not suit your skin, we recommend discontinuing use and contacting us for advice.

Is SERUM safe for those with a soy allergy?

SERUM contains soy-derived ingredients.
If you have a soy allergy, we recommend consulting with your physician before use.

I'm worried that just using BOOSTER and SERUM might not be moisturizing enough.

SERUM contains multiple moisturizing ingredients such as oils, diglycerin, and human-type ceramides.

However, depending on your skin condition, you may feel that the moisturizing effect is insufficient or that it feels a bit sticky.

In that case, please refer to the following suggestions:

For dry skin:
If your skin is extremely dry, SERUM alone may not be enough.
We recommend finishing your routine with an oil or cream to seal in moisture.

For oily or acne-prone skin:
Although the amounts of oleic acid and glycerin, which can serve as nutrients for acne-causing bacteria, are minimized, we recommend adjusting your skincare routine.

Since SERUM contains oils, consider skipping other oil-based products in the morning and using them only at night.
You can also adjust based on different areas of the face by reducing oil-containing products in oilier areas.

Do the surfactants and preservatives in SERUM negatively affect the skin’s microbiome?

To mix water and oil, the use of surfactants is unavoidable.
However, SERUM uses carefully selected surfactants that are gentle on the skin's microbiome.

It contains no bactericides or antimicrobial agents and instead uses grapefruit seed extract as a natural preservative.

Just like our BOOSTER, SERUM is formulated with your skin’s good bacteria in mind.
We hope it becomes an essential part of your daily skincare routine.

How should I store SERUM?

Please store it at room temperature, away from high humidity and direct sunlight.

What is the expiration date of SERUM?

Unopened, it has a shelf life of 3 years from the date of manufacture.
If there are no abnormalities such as separation, discoloration, or odor, it can be used within this period.
While the quality will not change immediately after opening, we recommend using it as soon as possible.
If you are unsure of the manufacturing date of your product, please contact us through the inquiry form.

What should I do if I experience itching or redness after using SERUM?

If you notice any abnormalities on your skin, stop using the product immediately.
SERUM is formulated with gentle ingredients, but skincare compatibility can vary from person to person.
If you have any concerns, please contact us through the inquiry form.

What is the main difference between SERUM ORIGINAL and SERUM REPAIR?

SERUM REPAIR is based on SERUM ORIGINAL and contains bakuchiol (a plant-derived form of vitamin A and a skin-conditioning ingredient).
It is formulated with ingredients that minimize the risk of irritation such as dryness, while maintaining a mildly acidic pH to help preserve healthy skin.
It provides radiance and firmness to aging skin, delivering both microbiome care and age-appropriate skincare benefits.
Unlike SERUM ORIGINAL, SERUM REPAIR does not contain 3-O-ethyl ascorbic acid (a vitamin C derivative and skin-conditioning ingredient),
making it a good option for those who are sensitive to vitamin C.

What is the texture, feel, and scent of SERUM REPAIR?

SERUM REPAIR has the following texture, feel, and scent:
・Slightly thick texture
・Feels smooth and gently protective on the skin
・Spreads easily
・Leaves skin feeling well-moisturized
・Almost fragrance-free

Will bakuchiol in SERUM REPAIR cause skin peeling?

Bakuchiol, a plant-derived ingredient similar to vitamin A, is generally considered low-irritant for the skin.
Compared to vitamin A, it is less likely to cause side effects such as peeling, dryness, or redness.
SERUM REPAIR has also passed human patch testing, confirming low irritation.
However, individual reactions may vary. If you notice any adverse effects, please discontinue use immediately.

What should I do if I experience itchiness after using SERUM REPAIR?

If you notice any irritation such as itchiness or redness, stop using the product immediately.
While SERUM REPAIR is made with low-irritant ingredients, compatibility with your skin may vary.
If you have any concerns, feel free to contact us.
