Hydroxypinacol Retinoid (HPR) is a revolutionary new retinoid that studies have shown works directly through agonists without metabolic conversion (retinoids generally require two steps of conversion in the skin) compared to other retinoid products, is less irritating, yet highly potent, more stable and less susceptible to oxidative failure. It is a safe, effective anti-aging (effective in reducing fine lines and wrinkles, fading pigmentation) and anti-acne ingredient.
