111SKIN Black Diamond Retinol Oil is a sophisticated night treatment designed to restore a smoother, more luminous complexion while you sleep. The Black Diamond Retinol Oil features a 2.5% blend of Retinol and Granactive Retinoid®, suspended in nourishing botanical oils that work overnight to soften the appearance of fine lines, refine skin texture and reveal a more even-looking tone.
Silky and lightweight on the skin, this retinol oil encourages natural skin renewal while helping dull, tired-looking skin regain its radiance. Ingredients such as Diacetyl Boldine and Fine Black Diamond Powder help enhance brightness and support the effective delivery of active ingredients, leaving the complexion looking clearer, smoother and beautifully polished by morning.
With continued use, the 111SKIN retinol oil helps skin appear more radiant and visibly refined. Clinical evaluation reported reduced wrinkle visibility after 4 weeks, while brightness improved by 30% after 8 weeks. In a consumer trial, 88% of participants agreed the formula felt comfortable on the skin, making it a considered choice for those seeking the benefits of retinoids within a luxurious evening ritual.
