Stable resveratrol form. Antioxidant and photoprotector.
Resveratrolarginine is a salt form of resveratrol with the amino acid arginine. A patented development addressing the main problem of pure resveratrol: low water solubility, instability under light and oxygen, and poor bioavailability in cosmetic formulas. The arginine salt unlocks the molecule's potential while preserving function. Where it is used. Anti-aging serums and emulsions, antioxidant creams for mature skin, products against blue light and infrared, formulas for pigmentation and tone evening. Concentrations 0.05-1%. In Spain: Sesderma Resveraderm, Mesoestetic Resveraplex, selected Cantabria and Talika lines. Mechanism. The resveratrol part scavenges free radicals through phenolic hydroxyl groups. It activates SIRT1 (sirtuin-1), an enzyme that regulates cellular metabolism and DNA repair. It inhibits tyrosinase – the enzyme for melanin synthesis – which justifies use in hyperpigmentation. The arginine part acts as an NO donor, improves skin microcirculation, and itself adds mild antioxidant activity. Evidence base. Topical resveratrol – evidence base B-C. The Buonocore 2012 RCT (n=50, 5% resveratrol + 0.5% delta-tocopherol over 60 days) showed improvement in roughness and pigmentation. Pavlou 2018 demonstrated antioxidant protection against UV-induced oxidative stress. Resveratrolarginine specifically was studied in Kirilenko 2019 in fibroblast culture, confirming a better stability and penetration profile compared with pure resveratrol. Safety. Pregnancy and breastfeeding – topical use is safe. Oral resveratrol at high doses (above 1.5 g/day) is not recommended in pregnancy due to theoretical estrogenic effects, but skin absorption from cosmetic formulas is minimal. Irritation is rare. Practical notes. Morning antioxidant – pairs well with vitamin C, niacinamide, and flavonoids. Expect light-protected packaging (dark glass, airless), otherwise activity drops within weeks. In INCI it usually sits at position 4-8. Not to be confused with oral resveratrol supplements – their evidence base for anti-aging effects is weak (Sahebkar 2013 meta-analysis) and does not transfer to topical use.

LowThe Evigrade extension adds an evidence panel to Wildberries, Goldapple, Letu, iHerb, Sephora and 12 more stores. This ingredient and every other one in the product show evidence-tier, allergen risk and pregnancy/lactation flags at a glance.
Resveratrolarginine is considered safe during pregnancy at typical cosmetic concentrations. Systemic absorption through the skin is minimal.
Resveratrolarginine suits: normal, dry, combination, oily, sensitive.
Salt of resveratrol with arginine – improved bioavailability of the antioxidant compared to pure resveratrol.
On the Fulton scale 0/5 – non-comedogenic. For acne-prone skin, a rating of 3 or higher suggests choosing an alternative.
The INCI name is Resveratrolarginine. It may also appear as: Resveratrol Arginate, ресвератроларгинин.
