INNBEAUTY PROJECT Pro C Serum ingredients: is it worth it?
A sophisticated brightening serum with real pigment-targeting ingredients, but the “15% vitamin C” headline overstates how much is proven from the mixed, partly derivative system.

The efficacy score is 4.3/5: tetrahexyldecyl ascorbate appears high in the list, while pure ascorbic acid, ethyl ascorbic acid, tranexamic acid, ferulic acid, alpha-arbutin, and hexylresorcinol provide a strong brightening strategy, but their exact concentrations and the formula’s pH are undisclosed. The oil-rich base and multiple vitamin C forms may improve tolerability and stability, yet this is not the same evidence profile as a clearly quantified 10–20% low-pH L-ascorbic-acid formula. Niacinamide, humectants, squalane, panthenol, allantoin, and centella support the base; gold, glutathione, and peptide/growth-factor-style marketing components should not be credited as meaningful efficacy drivers. The appended “Close Real Results...” text is packaging copy rather than an ingredient and should be disregarded.

EXTERNAL CITATIONS
Ascorbic Acid: Topical vitamin C has clinical evidence for antioxidant and pigment-related benefits when appropriately formulated.
Niacinamide: Topical niacinamide is supported for barrier function and uneven-tone improvement.
Tranexamic Acid: Topical tranexamic acid has clinical evidence for hyperpigmentation and melasma-support protocols.
Alpha-Arbutin: Alpha-arbutin is used as a topical tyrosinase-pathway and uneven-tone ingredient.
