Frequently Asked Questions

γ-linolenic acid is a component of the cell membrane of each cell that makes up the body. It plays a very important role in maintaining the softness (flexibility) of the cell membrane.

For example, it is said that by giving red blood cells flexibility, they can smoothly pass through narrow blood vessels. γ-linolenic acid is also expected to have various effects such as being a material for hormones, regulating lipid metabolism, and being beneficial for allergies. It is used as a treatment for atopic dermatitis in Europe and the United States, where it is considered to be good for allergies.

γ-linolenic acid works in various parts of the body, including: reducing menstrual pain and relieving menopausal symptoms by regulating female hormones, maintaining kidney function, normalizing lipid metabolism, and reducing inflammation and improving immunity.

γ-linolenic acid (GLA) is an essential fatty acid that is part of the lipid family of the five major nutrients that the body needs. However, it is difficult to obtain this nutrient from regular meals because it is only found in limited seeds such as borage, evening primrose, and breast milk.

Normally, nutrients obtained from meals are processed in the body to create necessary nutrients, but GLA is one nutrient that becomes difficult to produce due to minor factors such as aging and stress.

When GLA becomes difficult to produce in the body, the balance of prostaglandins is disrupted and can affect various parts of the body. GLA is metabolized from linoleic acid to γ-linolenic acid and dihomo-γ-linolenic acid, which is then metabolized to the prostaglandin 1 series. An enzyme called Δ6 desaturase is necessary to metabolize linoleic acid into γ-linolenic acid, but its activity can be hindered by minor factors, making it difficult for GLA to be produced in the body and affecting the balance of prostaglandin E that is produced downstream.

Prostaglandins are bioactive substances that are involved in the regulation of blood pressure, blood sugar, cholesterol levels, vascular dilation, bronchial dilation, uterine contraction, inflammation, and immunity.

For adults, the recommended daily dosage is 3-6 capsules. You can adjust the dosage within this range according to your physical condition.

Itchnon is a nutrient that we recommend for long-term use to maintain good health.

No, Itchynon is not a pharmaceutical drug. Please take it as part of your diet.

For infants and toddlers, the recommended dosage is about 2 capsules per day, and for elementary school children, the recommended dosage is 3-4 capsules per day.

Itchynon is a soft gelatin capsule. If you have difficulty swallowing it, you can soften the capsule by warming it up with hot water and then take the contents.

There are no restrictions on how many times a day you should apply the cream.

Itchnon AD Cream is a moisturizing cream designed to restore the skin’s barrier function from the inside. It does not contain any ingredients that cover the surface of the skin. If you feel that Itchnon AD Cream alone is not enough, we recommend layering it with oily ingredients.

Precaution 1: Please apply the cream without rubbing it in too hard. Apply a slightly larger amount and spread it gently using your fingertips.
Precaution 2: If you want to check if it suits your skin, please try it on an inconspicuous area such as the inside of your elbow.

Please apply it after washing your hands or face, and after your skin has been cleansed.

Makeup products contain a lot of oily components. If there is moisture on the skin, the oil-based dirt will not blend with the oil and cannot be washed away properly. Therefore, please use it on dry skin to ensure that the dirt is properly removed.

Acne is caused by inflammation in the skin. Dryness is the enemy of acne. When the skin is dry, it produces sebum to create a protective film. Excessive sebum secretion can cause inflammation and result in acne. You may think oil is not good for acne, but it is reasonable to use oil to remove oil-based dirt. First, replace the sebum with oil, and then balance the oil and water of the skin with appropriate skincare.

After removing makeup with S Cleansing Oil and washing away any remaining water-soluble dirt with S Cleansing Soap, please use the products according to your skin condition. For example, if your skin is dry, use S Moist Lotion and S Moist Cream. If you have skin problems, use S Essence Oil and S Moist Cream. In the morning, choose the appropriate product, such as Itch-no-Nan AD Cream, as a makeup base according to your skin condition.

Amino acid shampoo itself does not cause roughness in the hair. If the shampoo or conditioner you were using before contains ingredients that coat the surface of the hair, the lack of that coating effect can cause the hair to be in a bare state, and you may feel roughness when you start using it. However, we think that you will no longer feel roughness after using it for a while.

The skin is usually slightly acidic, but it becomes slightly alkaline after washing. This is because many cleansing ingredients are weakly alkaline. Shampoo’s cleansing ingredients also become weakly alkaline, and as a result, the hair also becomes weakly alkaline. When the hair becomes weakly alkaline, the cuticle spreads and causes tangles, roughness, and static electricity. Therefore, it is necessary to use a rinse or conditioner that can adjust the weak alkalinity. In addition, by supplementing the lipids necessary for repairing the inside of the hair, it delivers the necessary ingredients to the hair.

Amino acids are one of the cleansing ingredients. It is a recommended product for those who have problems with their scalp or hair. Cocoil glutamic acid TEA and cocamide DEA, as well as cocamidopropyl betaine, extracted from sugarcane and coconut, create a dense and fine foam to gently wash the hair.

The original role of shampoo is to “remove only dirt without depriving the necessary moisture from the scalp and hair.” We believe that this role can be fulfilled by amino acid cleansing ingredients.
