Dr.G Doopi Lab Cool Salt Long-lasting Cooling Tonic 100ml
For your scalp, not your face.
Soybean seed extract first, sea water second, plain water seventh.
Cold on contact, then gone.
What this tonic does
A 100 ml scalp tonic built on soybean seed extract and sea water, carrying four separate cooling agents with Salicylic Acid, Panthenol and Madecassoside, formulated to cool and settle an itchy scalp.
Doopi means scalp
The line name is 두피 랩 — Korean for scalp lab — and this is a spray applied to the roots, not a facial toner. The ingredient list confirms it: Hydrolyzed Keratin, Polyquaternium-51 and a cleansing-grade pareth sit in the middle of the formula, and none of those belong in a face product. Worth being clear about, because the packaging travels better than the name does.
Key ingredients
Ingredient · What it is, and what it is used for
- Glycine Max (Soybean) Seed Extract
- Extract of soybean seed.
- Maris Aqua (Sea Water)
- Seawater. Pulls water into the surface and holds it there; dissolves the rest so the formula stays one liquid.
- Menthol
- Terpene alcohol from mint. Carries scent; gives the cooling hit — the immediate cold hit.
- Menthyl Lactate
- Lactic acid ester of menthol. A cooling agent with less sting than menthol.
- Ethyl Menthane Carboxamide
- Synthetic cooling agent. Slower to start and longer to fade than menthol.
- Methyl Diisopropyl Propionamide
- Synthetic cooling agent. The longest-lasting of the four.
- Salicylic Acid
- Beta hydroxy acid. Oil-soluble, so it works inside the follicle rather than only on the surface.
- Panthenol
- Provitamin B5. Used to calm irritation, and pulls water into the surface and holds it there.
- Madecassoside
- Triterpene glycoside from Centella asiatica. Used to calm irritation.
- Hydrolyzed Keratin
- Keratin broken into smaller fragments.
- Salicornia Herbacea Extract
- Extract of glasswort, a salt-marsh plant.
- Enteromorpha Compressa Extract
- Extract of a green alga.
How the formula works together
Four cooling agents is the point of the product, and they are chosen for different timing. Menthol arrives immediately and fades fast. Menthyl Lactate is gentler and lasts a little longer. Ethyl Menthane Carboxamide and Methyl Diisopropyl Propionamide — known in the flavour trade as WS-3 and WS-23 — start slowly and hold for a long time. Stacked, they read as one long cool rather than a spike.
Underneath that sits actual scalp care: Salicylic Acid to keep the follicle clear, Panthenol and Madecassoside to settle irritation, Centella extract and Centella oil, and the mineral load from sea water and the salt-marsh plants. Rice bran oil and Biotin close it out.
Forty-four ingredients. Cooling agents are declared as fragrance material; there is no separate perfume.
Who it is for
Labelled for hot, itchy scalps. Spray-on, water-thin, no residue. Not a facial product.
How to use it
- Shake well before use.
