It is lightweight, non-greasy, and does not clog pores, making it safe for all skin types. It balances oil production, providing just enough moisture to keep the skin hydrated, supple & healthy. This Serum makes an essential addition to your skincare regimen as it will increase collagen & ceramide production activity when used along with Retinol, Vitamin C, & Multi-Peptides.
