Serums containing fruit acids, retinal, retinol and their derivatives, as well as benzoyl peroxide, salicylic acid, azelaic acid, and serums containing more than 1% ascorbyl palmitate in the formula are not recommended for daytime use.

Rohto CC Whitening Essence

Super Cabbage's whitening and spot-lightening essence can effectively lighten acne marks and spots. However, the VC it ​​contains is not pure VC. Its active ingredient is vitamin C palmitate, also known as vitamin C palmitate. This ingredient will be oxidized faster when encountering UVB and produce a large amount of toxicity.

The main ingredients of Duke's Color Repair are 5% arbutin glycosides, 5% thyme extract, 2% kojic acid, and 1% cucumber extract. The ingredients can not only moisturize, but also have antioxidant effects, can lighten pigments, and can also regulate oil secretion. The texture is a slightly viscous dark green liquid.

Eau Precieuse

French precious water is the savior of acne skin. This water contains salicylic acid and eucalyptus leaf essence, which can metabolize dead skin cells on the surface, clear closed pores, and also has a calming effect. The boric acid and tannic acid in it have an inhibitory effect on bacteria and fungi. Try not to use salicylic acid (SALICYLIC ACID) and fruit acid (ALPHA HYDROXY ACIDS) during the day. It can be used during the day, but sunscreen must be applied. This is because the ingredient has the function of exfoliating, which makes the skin sensitive and more susceptible to sunburn when exposed to ultraviolet rays.
