Overview
Anai RUI Serum is a drop-form facial serum with niacinamide and glycolic acid for combination, dry, normal and oily skin, sold in a 1.05 fl oz size.
The pairing of niacinamide with glycolic acid places it as a dual-purpose serum, niacinamide for tone and texture, glycolic acid as a chemical exfoliant, rather than a single-ingredient hydrator. That combination makes it more of an active treatment step than a plain moisturizing serum.
- 1.05 fl oz size
- Drop item form
- Niacinamide and glycolic acid
- Suited to combination, dry, normal and oily skin
Who it's for
Suits buyers wanting a broad-skin-type serum that pairs a brightening ingredient with an exfoliating acid. Less suited to anyone specifically seeking a gentle, exfoliant-free formula given the glycolic acid content.
