This carefully selected combination of active ingredients supports the skin in restoring its structural integrity, balances pigmentation irregularities, and protects against the effects of cellular stress. Each of the following active ingredients has been scientifically studied and fulfills a specific function within the skin's regeneration process.

Mechanism of action: Niacinamide regulates sebum production, strengthens the epidermal barrier function by increasing ceramide and free fatty acid levels, and inhibits the transfer of melanosomes to keratinocytes. It reduces transepidermal water loss (TEWL), improves skin elasticity, and inhibits pro-inflammatory cytokines such as IL-1α, thereby also reducing inflammation-related pigmentation.

Clinical relevance: When applied topically (2–5%), niacinamide shows significant reductions in hyperpigmentation (anti-redness), pore size, and sebum production. Several weeks of use lead to a visible improvement in skin tone homogeneity, skin texture, and elasticity.

Tranexamic acid (trans-4-aminomethylcyclohexanecarboxylic acid) is a synthetically produced derivative of the amino acid lysine. In cosmetic formulations, it is typically used at a concentration of approximately 2%. Its mechanism of action is based on the inhibition of the plasminogen-plasmin system, a naturally occurring signaling pathway that, among other things, activates inflammatory mediators. This system promotes the activity of tyrosinase, a key enzyme in melanin production, via messenger substances such as prostaglandin E2 and α-MSH (alpha-melanocyte-stimulating hormone, which regulates the production of the skin pigment melanin). By modulating this signaling pathway, tranexamic acid can inhibit excessive pigmentation and thus contribute to a more even complexion.

Furthermore, tranexamic acid influences VEGF-mediated hyperflow, an increased blood flow in fine skin vessels that can be associated with visible redness. This can reduce the appearance of skin redness. There is also evidence of modulation of NF-κB (a key regulator of inflammatory processes), which could further explain its skin-soothing and anti-inflammatory effects. Studies suggest that tranexamic acid can also stabilize the skin barrier and improve skin texture. In combination with niacinamide, this effect is specifically enhanced and makes it suitable even for sensitive skin.

Mechanism of action: Ectoin is a so-called extremolyte, a cyclic amino acid derivative that protects microorganisms from extreme environmental conditions. In the skin, it acts as a natural cell protection factor by stabilizing the structure of cell membranes, enzymes, and proteins. Ectoin binds water in a hydration shell, protects DNA from oxidative damage, and modulates inflammatory mediators such as TNF-α.

Clinical relevance: In application studies, ectoine (1–2%) showed significantly reduced signs of irritative and inflammatory skin conditions (e.g., due to UV radiation, dryness, or environmental stress). Skin hydration was stabilized, redness was reduced, and the barrier function was strengthened.

Mechanism of action: The boswellic acids from the resin of the Boswellia serrata plant inhibit 5-lipoxygenase – a key enzyme in the inflammatory process. This reduces the formation of pro-inflammatory leukotrienes. In addition, Boswellia has an antioxidant effect, reduces MMP (matrix metalloproteinase) activity, and thus protects against collagen degradation.

Clinical relevance: In topical form, Boswellia extracts have been clinically proven to reduce signs of inflammation, redness, and itching. Tolerance is significantly improved, especially in irritated or stressed skin, with additional anti-aging potential through collagen protection.

Mechanism of action: Resveratrol is a polyphenolic antioxidant that neutralizes free radicals and promotes cellular repair and longevity processes by activating the sirtuin family (especially SIRT1). It inhibits inflammatory signaling pathways (e.g., NF-κB) and protects mitochondrial function. Furthermore, it slows down UV-induced skin damage and regulates melanin synthesis.

Clinical relevance: Topically formulated resveratrol may help improve skin elasticity, reduce fine lines, and mitigate oxidative stress marker status after UV exposure.
