• Marine minerals + sea water
  • Gently refines pores
  • Balances and hydrates
  • Lightweight, no sticky residue

What it is

A marine-based toning solution from Percent Science, a Korean skincare brand built around patented ingredient complexes. It uses sea-derived ingredients to purify and rebalance skin after cleansing.

What it does

Sea water and fucoidan recharge moisture and soothe, while betaine salicylate and succinic acid gently refine pores and smooth texture. It absorbs fast with no sticky residue, leaving skin balanced and ready for serum.

Who it's for

All skin types, especially anyone who wants a toner that does more than just feel nice: real pore and texture care.

How to use

How much: A splash, or enough to dampen a cotton pad.

1. After cleansing, apply with hands or a cotton pad.
2. Sweep over the face, avoiding the eyes.
3. Follow with serum and moisturizer while skin is still slightly damp.

Where it fits: Right after cleansing, before serum, morning and night.

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.
