In this post, I will provide a quick review of each of the products that are listed here. Then, I will share my favorite products for lightening and repairing the dark spots and wrinkles on your skin. I have a long standing interest in skin health and skin care. I have been a dermatologist for 35 years. I have a doctorate in the sciences and have completed a medical residency and a fellowship in dermatology. I am a board certified internist. I work in private practice and my practice is located in a large city center. There are a lot of products out there. Here is a quick guide: 1. I don't recommend using retinoids and/or salicylic acid (SSA) together. Retinoids and SSA are two very different ingredients. They have different mechanisms of action, and are not meant to be used in combination. If you use SSA, there is a possibility of irritation and the results are less. 2. I don't recommend the use of vitamin C alone, since it causes dryness in the skin. 3. I have been doing skin care for more than 15 years. I have never heard of an "all in one cream" that makes your skin so dry. It can cause irritation in some people, but that is not my experience.
