• Booster + cream duo
  • Preps skin, then seals it in
  • Targets wrinkles and firmness
  • Simpler two-step routine

What it is

A two-step anti-aging set from Percent Science, a Korean skincare brand built around patented ingredient complexes. The booster essence preps skin for absorption and the cream finishes with hydration and wrinkle care.

What it does

The essence hydrates and primes skin so actives absorb better, while the ceramide-rich cream smooths wrinkles, firms, and strengthens the barrier. A complete routine in two steps for anyone who does not want a long lineup.

Who it's for

Anyone who wants visible anti-aging care with minimal steps, or a simpler entry point into the Cellinol-5 line.

How to use

How much: Essence: a few drops. Cream: a dime-sized amount.

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

Where it fits: After cleansing: essence first, cream second. That is the whole routine.

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.
