Green Cream High Potency Retinol Level 9 is an effective treatment for the following conditions: Acne and acne scarring Age Spots and pigmentation Minimizing appearance of pores Repairing sun damaged skin cells Improving skin tone and texture Green Cream 0.9% stimulates exfoliation of dull-looking epidermal cells by accelerating skin cell turnover time, from the standard 30 to 35 day cycle, to 5 to 6 days, causing the skin to appear smoother and brighter. It also repairs cellular structure damage gradually in the epidermal cells, as well as in the dermal collagen and small blood vessels. This cream will even help shrink oil glands, which in turn reduces pore size and diminishes scars. Another effect of regular use is that Green Cream will held build "infrastructure" by stimulating new collagen and a new thicker, plumper epidermis. For sensitive skin types and people that want to ease into a retinoid regimen start with our Level 3-strength, high potency retinol. Though Level 3 is the mildest strength, you can still expect to see visible results after a few months of daily use.
