• Booster + cream duo
  • Calms redness, preps skin
  • Controls oil, hydrates
  • Gentle two-step routine

What it is

A two-step acne care set from Percent Science, a Korean skincare brand built around patented ingredient complexes. The booster essence calms and preps, and the cream treats and balances.

What it does

The booster reduces redness and irritation with a cooling feel while helping skin absorb what comes next. The cream then controls sebum, calms breakouts, and keeps moisture balanced with a light, fresh finish.

Who it's for

Acne-prone and sensitive skin that wants a short, gentle routine focused on calming and oil control.

How to use

How much: Booster: a few drops. Cream: a pea-sized amount.

1. Apply the booster to clean skin.
2. Follow with the cream once it absorbs.
3. Use morning and night.

Where it fits: After cleansing: booster first, cream second.

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.
