Ingredient callouts

  • this product contains an effective form of Retinoids (vitamin A): retinal 1.60% - 1.90%. Retinoids are potent multitasking actives. They work to improve and prevent early signs of aging, reduce hyperpigmentation (age spots and post-acne marks), and prevent inflamed blemishes and clogged pores. The downside of Retinoids is that they can be irritating. If you are not already using a Retinoid in your routine, it is best to start slowly and apply the Retinoid product only a few times per week. If your skin tolerates it well, you can gradually increase the frequency to daily.
  • Humectants (glycerin 0.20% - 0.40% and saccharomyces ferment filtrate 0.80% - 1.20%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
