The Celestial Black Diamond Retinol Oil is a high strength retinol treatment designed as the ultimate solution to transform the skin. Retinol speeds up cell-turnover to effectively treat signs of ageing. Retinol is also effective for resurfacing the skin to target texture related problems, such as scarring, pigmentation, open pores and post-acne issues. The Retinol Oil delivers 1% of pure retinol deep into the skin with the aid of Diamond Particles. The retinol is suspended in a blend of eight natural oils to reduce irritation and dryness usually associated with high-percentage retinol treatments.
