Ingredients

Retinol accelerates cell turnover and stimulates collagen synthesis for smoother, Green Tea Extract delivers epigallocatechin gallate (EGCG), and Aloe Vera completes the formula as a delivers instant soothing hydration with natural anti-inflammatory compounds.

Retinol converts to retinoic acid inside the skin, where it binds to nuclear receptors that regulate gene expression for cell turnover and collagen production. Unlike prescription retinoids that work immediately (and irritate), retinol converts gradually, offering a sustained effect with less downtime. The compounding effect means texture, fine lines, and tone all improve progressively over 8 to 12 weeks.
