Protinol is an ingredient patented by Avon, which means you’ll only find it in Avon skincare products.

The key product you’ll find it in is the new Anew Renewal Power Serum, which promises to deliver considerably healthier, more radiant skin in just seven days, having been tested on a range of skin types, tones and ages.

Those benefits include firmer and smoother looking skin along with a radiant glow.

The lightweight serum absorbs beautifully into skin, and it’s been developed with a blend of Protinol and niacinamide, a much-loved ingredient that helps to protect collagen while promoting even skin tone, targeting blemishes and reducing the appearance of pores.

Best used at night time after cleansing, it can also be paired with Avon’s day and night cream – which, together, will pack a triple Protinol punch.
