Niacinamide (4%): Vitamin B3 with a multi-resolving effect on blemish-prone skin. It strengthens the skin barrier by increasing ceramide synthesis, reduces transepidermal water loss, and modulates the inflammatory response of keratinocytes, thus reducing redness and sensitivity. It also acts as a sebum regulator by functionally inhibiting 5-α-reductase, helping to improve the texture and overall appearance of oily skin.

Salicylic Acid (1%): A lipophilic beta-hydroxy acid with the ability to penetrate the follicle, promoting controlled exfoliation and unclogging pores. It improves texture, reduces comedones, and helps balance sebum production (keratolytic and sebum-regulating function). Sodium Lactate (7.12%): An alpha-hydroxy acid and component of the Natural Moisturizing Factor. It acts as an osmotically active humectant, promoting water uptake and retention in the stratum corneum. It contributes to maintaining cohesion between corneocytes and to the renewal of the stratum corneum, improving skin smoothness, elasticity, and comfort.

Epilobium angustifolium (3%): Botanical extract rich in biophenols with anti-inflammatory and antioxidant properties. It reduces the release of pro-inflammatory mediators and helps control sebum. It acts as a balancing agent for the skin microbiota, reducing reactivity and promoting a more stable skin environment.
