Retinoids are gold-standard ingredients for stimulating collagen production, combating photoaging, and preventing breakouts.  Verso's Retinol 8 active ingredient, unique to the brand, is a hydrating form of retinol that delivers powerful results without the usual resultant redness and irritation.  Short-contact retinoid treatment has been popular in Europe for years, and this Stockholm-based company is bringing it to the U.S. with these innovative sheet masks.  They deliver a potent dose of retinol while drenching skin in hydration, making them an ideal add-on for those with sensitive skin who haven't been able to tolerate retinol previously, or for retinol-lovers who want to supercharge their regimen.
