A competent hydrating serum with real brightening support, but the peptide-and-bakuchiol hype outruns the likely treatment strength.

READ MORE

The efficacy score is 4.2/5: water, glycols, glycerin, betaine, niacinamide at position 5, and multiple hyaluronic-acid forms provide a credible hydration base, while niacinamide can support brightening and barrier function. Bakuchiol and copper tripeptide-1 appear after the main base and are not disclosed at meaningful percentages, so their anti-aging contribution cannot be assumed to be strong; the numerous peptides and collagen are supportive marketing/formulation features rather than reliable reasons to award a high score. No product pH or packaging information was provided, and the presence of alcohol adds a formulation caveat without automatically making the serum unsafe.
