What it is
Just 3 minutes of daily peeling cleansing will make a difference to your skin... This transparent soap contains 4% AHA glycolic acid, a peeling ingredient. It gently removes dead skin cells without the tingling sensation that peeling can cause. Just 3 minutes of daily cleansing will remove dead skin like dandruff! Simply replace your current soap with "Aina Soap." Compared to full-body peeling, it's easy and cost-effective. It can also be used on the entire body. Rinse with a towel after washing to remove an astounding amount of dead skin! *Also recommended for treating acne on the back, buttocks, and other areas of the body! *Fragrance-free, colorant-free, mineral oil-free, paraben-free, fluorescent agent-free, and no previously designated ingredients *Patch tested, allergy tested, and non-comedogenic. ━ ... ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━After washing your face, moisturize with lotion or emulsion. If you feel a tightness on your face or body after using the soap, moisturize. The tightness will decrease with use. A white, powdery feeling may initially appear around the mouth, but this will disappear with use. (This may vary from person to person, so discontinue use if you feel a strong tightness.)When going out, use UV protection and protect your skin from daytime UV rays with an SPF of 30 or higher.Storage and Handling Precautions: Due to its soluble nature, be sure to drain the water thoroughly after use and store in a well-ventilated place. Keep in mind that storing in a moist or humid environment will cause rapid dissolution. Also, do not store in high temperatures or in direct sunlight. Caution: If you have any skin or constitutional abnormalities, or if you experience any skin abnormalities such as rash, redness, itchiness, or unusual irritation during or after use, discontinue use and consult a dermatologist. Continuing to use the soap may worsen the symptoms. *However, since this soap contains glycolic acid, you may experience a slight tingling sensation. *If you have dry skin, please use a moisturizing cream after use. Be careful not to get the soap in your eyes or mucous membranes while washing. If it gets in your eyes, rinse immediately with water and consult an ophthalmologist if you experience persistent pain or other symptoms. Keep out of reach of infants and children.
Ingredients
Soap base (vegetable-based), water, sucrose, glycerin, sodium glycolate, ethanol, tocopherol (natural vitamin E), sorbitan stearate
How to use
Use daily when washing your face and bathing, excluding the area around the eyes. You may experience a particularly strong tingling sensation around the eyes, where the skin is thin. If you experience excessive irritation or dryness, adjust the frequency of use to once a day, once every two days, or once a week. Add lukewarm water and lather well. (Cold water may not lather well.) After lathering in your palms, massage carefully into sensitive areas, such as the forehead, around the nostrils, and around the mouth, taking care not to rub. Rinse after 30 seconds to 1 minute. If soapy ingredients remain on your skin, they can cause problems, so be sure to rinse thoroughly.
