Niacinamide (5%): A derivative of vitamin B3 with seborregulating, anti-inflammatory, hydrating, and skin tone-evening properties. It inhibits 5-alpha reductase, helping to normalize sebum production and improve the appearance of pores and imperfections. Its anti-inflammatory activity is due to the inhibition of pro-inflammatory cytokines (IL-1α, IL-6, TNF-α) and the NF-κB factor, reducing redness and perifollicular inflammation. It strengthens the barrier function by stimulating ceramide synthesis and decreasing transepidermal water loss (TEWL), providing greater skin comfort and better tolerance to seborregulating treatments.

Azelaic Acid (3%): A water-soluble derivative of azelaic acid with excellent tolerance and high bioavailability. It inhibits tyrosinase, exerting a selective depigmenting action, and modulates 5-alpha reductase, helping to normalize sebaceous production. It regulates follicular keratinization, promoting uniform desquamation and preventing pore obstruction. Its anti-inflammatory and antioxidant activity reduces pro-inflammatory mediators and improves the follicular microenvironment, contributing to more even and clearer skin.

Arbutin (2.5%): A depigmenting agent that inhibits tyrosinase, helping to reduce the size and intensity of post-inflammatory spots. It helps to even out skin tone, preventing the formation of residual spots after inflammatory outbreaks and improving the overall appearance of blemish-prone skin.

Marine Plankton (2%): Marine-derived exopolysaccharides with an immediate tightening effect and anti-wrinkle activity. They improve superficial firmness and help to smooth the skin's microrelief, promoting a smoother and more refined appearance.

High Molecular Weight Hyaluronic Acid: A molecule with high hygroscopic capacity that remains on the skin's surface, forming a protective film. This film retains moisture, prevents transepidermal water loss (TEWL), and provides an immediate plumping effect, smoothing fine lines.

Vitamin E: A lipophilic antioxidant that protects against free radicals and strengthens the barrier function. It helps to reduce oxidation associated with inflammatory processes typical of imperfections.

Vitamin C: An antioxidant active with brightening action that helps to improve luminosity and even out skin tone. It helps to reduce hyperpigmentation and enhances the depigmenting action of arbutin and azelaic acid, protecting the skin against oxidative stress associated with acneic processes.
