| Verdict | Beyoung's Booster Serum is the Brazilian anti-aging serum that punches above its price with one standout ingredient: copper tripeptide-1 (GHK-Cu). This peptide has some of the strongest clinical evidence of any anti-aging ingredient — published studies show it stimulates collagen synthesis, reduces fine lines, and improves skin firmness. Most copper peptide serums cost $50-100 (NIOD, The Ordinary). Beyoung delivers it at R$90 (~$18). Hydrolyzed vegetable protein provides additional amino acid support for collagen production. Trehalose — a stress-protecting sugar found in organisms that survive extreme dehydration — helps skin retain moisture under environmental stress. Red clover (Trifolium pratense) extract provides phytoestrogen support for mature skin. The formula is minimal and functional — no vitamin C, no retinol, just copper peptide infrastructure with supporting cast. This is the Brazilian alternative to NIOD's CAIS for a fraction of the price. | Sallve is Brazil's leading clean-actives indie brand and the Sérum Antiacne is their acne workhorse. 2% salicylic acid, niacinamide, tea tree leaf oil, willow bark extract for natural BHA support, plus buchu (Barosma Betulina) — a South American botanical that's uncommon outside Brazil. Alcohol-free, fragrance-free formula. |
