How to Remove Milia Through Chemical Exfoliation
Chemical exfoliation (acid peeling) utilizes acidic ingredients to remove aged keratin from the skin, promote metabolism, and improve skin condition. The general reference price for chemical exfoliation ranges from 100 to 800 yuan per session, and visible improvement is typically observed after 1 to 3 months. Common methods for removing milia through chemical exfoliation include selecting the appropriate acid, performing a skin test, cleansing the skin, proper acid application, and post-peel skincare.

1. Selecting the Appropriate Acid
Salicylic acid is commonly used as it is lipid-soluble and can effectively penetrate pores, dissolving milia caused by pore blockage. Other options include alpha hydroxy acids (AHAs) such as glycolic acid and lactic acid, which accelerate keratin turnover and promote skin renewal.
2. Performing a Skin Test
Before applying acid to a large area, perform a patch test on a small area of skin, such as behind the ear. Apply a small amount of acid solution to the test area and wait 24–48 hours to observe for any allergic reactions, such as redness, itching, or swelling. Proceed to the next step only if no adverse reaction occurs.
3. Cleansing the Skin
Thoroughly cleanse the skin before applying acid. Use a gentle facial cleanser to remove surface impurities, oils, and makeup residue. After cleansing, gently pat the skin dry with a clean towel—avoid rubbing vigorously, which may damage the skin.
4. Proper Acid Application
Using a cotton pad or swab, apply an appropriate amount of acid solution gently to the areas affected by milia. Be careful to avoid the delicate skin around the eyes. If using acid-impregnated patches, simply apply the patch to the affected area, but avoid leaving it on for too long.
5. Post-Peel Skincare
Following acid application, the skin's barrier function is temporarily weakened. Rinse the acid off thoroughly with water, and then apply gentle moisturizing products containing ingredients such as ceramides or hyaluronic acid to help restore the skin barrier. Strict sun protection measures should also be followed.
Maintaining healthy lifestyle habits is essential. Avoid excessive fatigue and strenuous exercise, which may cause physical discomfort. Additionally, maintaining skin hygiene in daily life contributes to overall skin health.
