Cosmetics Formulation Development

I would like to inquire about the whitening substance. Which one works well? does not irritate the skin Do you see results similar to using steroids? And which substance is suitable for people who have used steroids in the past? Thank you.

Hello, skin that has been using steroids continuously. during the discontinuation of steroids will find that there is an allergy problem even without using anything or using anything It's like having an allergic reaction to everything. I recommend you to try a sample formula that helps relieve. And nourish the skin back to be strong as before, which is Skin Barrier Cream by applying a thick layer of skin every day before bedtime. For at least 1 month, symptoms will improve. for group ingredients ไวท์เทนนิ่งที่ไม่ระคายเคืองผิว สามารถคลิ๊กดูที่หมวดนี้คะ
