Now designed with a slower-release formula, the NIP+FAB Retinol Fix Serum Extreme helps to reduce the appearance of the visible signs of ageing, including fine lines, dullness and a loss of firmness.The balm-like serum is powered by a 3% time-release retinol complex, with 0.3% encapsulated pure retinol for a gradual release. Bakuchiol, a natural retinol alternative, helps to visibly plump fine lines and minimise the look of uneven tone. Supported by a peptide complex to refine the look of texture, the serum leaves skin with a smoother, plumper appearance.
