Your lady cream may be "fighting" the essence.
Have you ever encountered this situation: clearly using word-of-mouth skin care products, but your skin is getting worse and worse? The problem may not be the product itself, but something is wrong with your skincare mix! Just like food, the ingredients of skin care products will be "contradictory".
? These ingredients must not be "neighbors"
① Retinol + high concentration of acids = double stimulation
This pair can be called "bad face CP"
Retinol needs to work in a neutral pH environment
Acids can disrupt skin pH balance
Results: 1 +1 < 1, the stimulation was doubled and the effect was reduced by half
② Vitamin C + some active ingredients = mutual harm
Vitamin C may produce niacin when encountering niacinamide, which irritates the skin
Vitamin C and retinol will cancel each other's effects when used together
The meeting of copper peptides and vitamin C will make both ineffective
③ Superimposed use of exfoliating products = damaged barrier
Salicylic acid + fruit acid + physical scrub
Excessive exfoliation damages the skin barrier
Causes sensitivity, redness, stinging
