When people ask Medical Esthetician Pascale Wellin what the number one thing she suggests people should use, she always says it's a vitamin C serum. It ticks all the boxes: helps reduce discoloration, wrinkles, sun damage, while restoring structure and elasticity. Pascale's go-to is the Coui Skincare Natural Vitamin C which contains 20% of the star ingredient. To work the best, vitamin C serums are usually applied at night since they tend to sensitize the skin and sun exposure could cause irritation. Since most of the world is shut down, why not take advantage of this opportunity to try something new? Watch Pascale's full review above for her esthetician's view on Vitamin C serums.
