Pepha-tight is a cosmetic additive that functions as a skin tightener. It provides immediate reduction of fine lines and wrinkles. It has strong firming properties and protects skin from oxidizing agents and free radicals. It also increases collagen production and produces incredible anti-aging effects. It is harvested from the microalgae called Nannochloropsis oculata. These algae contain high levels of polyunsaturated fat (the healthy kind also found in nuts, seeds, and fish), which make it highly moisturizing without being overly oily. Pepha-tight is a relatively new and innovative skin care additive.
