Ingredient callouts

  • this product contains an effective form of Retinoids (vitamin A): retinal 0.25% - 0.45%. 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 (sodium hyaluronate 0.35% - 0.60% and glycerin 4.10% - 5.00%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
