• Niacinamide + peptides for acne
  • Calms redness and inflammation
  • Hypoallergenic tested formula
  • Pink tint from vitamin B12

What it is

An acne-care serum from Percent Science, a Korean skincare brand built around patented ingredient complexes. It is built for sensitive, breakout-prone skin and has completed hypoallergenic testing.

What it does

Niacinamide and antimicrobial peptides work on excess oil and the bacteria behind breakouts, while licorice, allantoin, and vitamin B12 calm redness and irritation. It builds a stronger barrier so skin stays clearer between breakouts.

Who it's for

Sensitive, acne-prone skin that needs real treatment without harsh actives. The pink tint is just vitamin B12, not artificial color.

How to use

How much: A pea-sized amount for the full face.

1. Apply to clean skin, morning and night.
2. Let it absorb before layering cream.
3. The supplier notes best results with use at least twice daily.

Where it fits: After cleansing, before cream or moisturizer.

About the brand

PERCENT SCIENCE

Clinical Korean skincare, demystified

Percent Science is a skincare brand developed by biotech researchers, originally formulated for high-end dermatology and aesthetic clinics in Korea before debuting in the U.S. Their formulas use carefully selected ingredients from Germany, Korea, and France, paired with a patented delivery technology for deep absorption. The whole point is medical-grade skincare without the medical-grade gatekeeping.

We stock Percent Science because it brings clinic-level anti-aging formulas to the shelf at prices that don't require a dermatologist's budget.

Skincare questions, answered

Where does this go in my routine?

Thinnest to thickest: cleanser, toner, serum, moisturizer, then SPF in the morning. This product's How to use section above tells you its exact step.

When will I see results?

Give it 4 to 6 weeks of consistent use — that's one full skin cycle. Hydration shows up in days; tone and texture take weeks. If your skin reacts badly (stinging, new breakouts that don't settle within a week), stop using it.

I have sensitive skin. Will this irritate me?

Patch test first: a dab behind your ear or along your jawline, wait 24 hours. Fragrance-free formulas are the safest bet for reactive skin — check the highlights on this page.
