Nowadays, we often pay more attention to skin care methods.
Dermatologist Dr. Y. Claire Chang of Union Square Laser Dermatology Institute will share notes when combining ingredients in cosmetics.
Ingredients in cosmetics are `incompatible` with each other:
`Incompatible` pair 1: Vitamin C – Retinol
Claire Chang said: Vitamin C is an antioxidant that helps us fight external environmental impacts including ultraviolet rays.

“Retinol and Retinoid are a derivative of vitamin A that help lighten brown spots and erase wrinkles on the skin” – Claire Chang.
Although the uses are quite similar to the uses, we cannot combine these two products together.
If you want to use both ingredients, Claire Chang recommends using vitamin C in the morning along with sunscreen.
`Incompatible` pair 2: AHA/BHA – Retinol
Products containing AHA on the market are usually: Glycolic, Lactic and Citric acid.

“AHA and BHA are often used to chemically exfoliate the skin to help brighten and even out skin tone.
`Incompatible` pair 3: Benzoyl peroxide – Vitamin C
Claire Chang advises us not to combine Benzoyl peroxide with vitamin C. Because the medicinal properties of these two products are antagonistic.

In case we want to combine both products together, we should leave a few minutes between the two products.
