"This stuff is great, very good quality, very good value, really helped improve my skin"

Best For
Watch Out
- !Pilling risk — apply before thicker serums or creams, not over them
- !10% niacinamide is on the higher end; those with reactive or rosacea-prone skin should patch test first
- !Not ideal for dry or dehydrated skin as the primary moisturising serum — pair with a richer moisturiser
- !Niacinamide + Vitamin C layering can reduce efficacy of both — space them apart in routine
