The gold standard in skin renewal. Power R1% is our clinical strength retinol, made for women who are serious about visible change. Tired, pigmented or ageing skin is exactly its territory: it resurfaces and refines, so texture looks smoother, pores look tighter and tone looks brighter and more even. Stabilised retinol, a proven vitamin A derivative, supports your skin's natural renewal, helps clear congestion and softens fine lines and the marks breakouts leave behind. Saccharide isomerate offsets the dryness retinol can bring, while tocopherol and milk thistle calm and protect your barrier as your skin adjusts. And an honest timescale: visible progress builds over six to twelve weeks. Evenings only, building up gradually from twice a week. Follow with Cream Drench or Cream Lift, and wear Solar 50 every day while you're using retinol. Wear it for 60 days, and if your skin does not love it, every penny back.
