Retinol Serum


With 0.3% Retinol, this efficacious serum has the strongest concentration of Retinol on the market for effective anti-wrinkle power, whilst also being completely safe for skin. Retinol helps to visibly reduce the appearance of fine lines and wrinkles while improving skin radiance and luminosity, encouraging increased cell turnover. Kakadu Plum (known to have 55x more Vitamin C than oranges) brightens the complexion, reducing hyper-pigmentation and protecting from harsh environmental aggressors such as pollution.
