1. Ignore the ingredients of cosmetics
Each cosmetic product has its ingredients table with different functions. And in a product with so many ingredients, it's inevitable that there will be a few ingredients that make your skin allergic. Therefore, it is necessary to know the ingredients of the cosmetic to buy.

Women with sensitive skin have to pay more attention to this issue. Because sensitive skin will not like strong cleansers in cosmetics at all.
The study of cosmetic ingredients should be seriously invested by women, avoiding use cases because of following the word of mouth because some products will suit one skin but cause allergies to other skin. .
(***For example: When buying sunscreen, you should prioritize products with ingredients retinol. Because this substance is very good for the process of blurring dark spots on the skin.)
In short, when buying anything that is not just cosmetic, everyone should develop a habit of checking the ingredients table to avoid unintended problems. Especially for cosmetics that are applied directly to the skin, it should pay more attention.
