I’ve just bought a Retinol A cream to fade pigmentation that’s developed on my face due to my slack approach to using sun block. The instructions don’t say anything about using it in conjunction with a daily moisturiser or night cream. To start application is only recommended 1/2 a week until the skin becomes accustomed to it so it’s not an immediate problem. But you are supposed to build up daily usage.
Does anyone use a similar product? Do you apply it before or after other creams? Is it best to use in the morning or night?
