Whitening is to make the skin glow again from the inside out, and at the same time protect the skin from external stimuli. Sunscreen is the most important thing in whitening all the year round. I used to be overworked, under great psychological pressure, with abnormal work and rest and unbalanced diet, which made the epidermal cells lose their original vitality and regeneration ability, and the skin looked dull, dull and inelastic. At first, many methods didn't work. Fortunately, I took Chinese medicine from Taobao Youzhidian and my skin got better. I really appreciate it. You can try.
