Vitamin C and Retinol are highly effective brightening ingredients. However, their activity makes each ingredient tricky to work with on its own, and virtually impossible to incorporate them together into the same formulation. We created REVERSE Dual Active Brightening Complex featuring a Vitamin C formula in one tube and a stable Retinol formula in a separate tube. Mixing these two formulations together immediately before application ensures optimal skin brightening activity. The results are well worth removing the extra cap as Retinol also helps to reduce the appearance of lines and wrinkles.
