• Serum + booster + cream
  • Full acne routine in three steps
  • Calms, treats, and hydrates
  • Cooling, gentle formulas

What it is

The full Dexynol-16.3 acne routine from Percent Science, a Korean skincare brand built around patented ingredient complexes. Serum, booster essence, and cream work as a three-step system for troubled skin.

What it does

The booster calms redness and preps skin, the peptide serum treats breakouts and builds the barrier, and the cream controls oil while keeping hydration balanced. Together they cover every stage of acne care in one routine.

Who it's for

Acne-prone, sensitive skin that needs a complete routine without harsh actives or complicated layering.

How to use

How much: Booster: a few drops. Serum: pea-sized. Cream: thin layer.

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

Where it fits: After cleansing: booster, serum, cream. That is the full routine.

Why we stock it

We stock this because acne routines usually force you to mix and match and hope. This trio was built as one system, so the steps actually complement each other.

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.
