Niacinamide 5% + Hyaluronic Acid.

evidence-aligned niacinamide.

Niacinamide at the clinically validated 5% — not the 10-12% trend that triggers more flushing without measurable extra benefit. Pleasant gel-serum, hyaluronic adjunct, and a price that lets you actually use it daily.

The scorecard.

Active concentration
5% sits at the dose-response inflection; the 'trendy' 10% adds flushing risk without proportional benefit.

Frequently asked.

Why 5% and not 10%?

Niacinamide's dose-response curve flattens above 5%. Higher concentrations risk flushing and irritation in 8-15% of users without a corresponding clinical gain. 5% is the evidence-led sweet spot.

Layer with vitamin C?

Yes — both AM is fine on tolerant skin. Older 'don't layer' advice was based on out-of-date stability concerns; modern formulas are stable together.

How long until I see anything?

Pigment / pore: 8-12 weeks. Barrier / oil: 2-4 weeks. Photograph baseline; measurement matters.

Pregnancy?

Yes — niacinamide is one of the safest pregnancy actives. Use freely.
