02 / 03 · What it does
A signal, not a filler.
On skin it works as a conditioning ingredient. Paired with peptides and niacinamide, it helps skin look smoother and more even, and feel stronger over the weeks you use it.
03 / 03 · How much
1.0%, on purpose.
Enough to matter, low enough for daily use. The serum carries our highest dose; toner and mask carry 0.5%.
These are cosmetic claims about how skin looks and feels. STRAND SEOUL products are not drugs and do not treat any condition.

Localized for the US
Same formula.
Two labels.
A Korean box can't go on a US shelf as it is. Claims, units, ingredient names and the responsible person all change. Watch the serum's label switch.
- ClaimsKorean "재생" (regeneration) and "주름 개선" read as drug claims in the US. They become how skin looks and feels.
- UnitsNet contents in fluid ounces first, metric second.
- IngredientsKorean ingredient names become INCI names, in the same descending order.

Notes from the bathroom shelf
Skin that looks rested, even when you aren't.
“The serum dries down fast enough that I actually use it every morning. My skin looks more even under makeup.”
“First cream that doesn't pill under sunscreen. Feels like nothing, but my cheeks stopped feeling tight by noon.”
“I do the mask two nights a week. The mornings after, my skin looks rested even when I am not.”
