Description
Cow Brand Skin Life Medicated Acne Lotion, 150 ml
Overview
Skin Life is Cow Brand's acne line, and this is the lotion step: a light, oil-free, fragrance-free toner registered in Japan as a 医薬部外品 quasi-drug. It is one of the cheapest acne products on a Japanese pharmacy shelf and one of the most widely used.
Two declared actives do the work — isopropylmethylphenol, an antibacterial, and dipotassium glycyrrhizate for irritation — over a base carrying three vitamin C derivatives, Centella asiatica and coix seed extract.

Who Is This For?
- Oily or combination skin with recurring breakouts, looking for a lotion step that will not add oil
- Teenage and young-adult skin, which is the market this line was built for in Japan
- People who want a quasi-drug rather than a plain cosmetic at the toner step
- Anyone who wants an unscented product on skin that is already inflamed
- Not for you if alcohol stings your skin, if you avoid parabens, or if you have dry or barrier-damaged skin
How to Use
- Cleanse the face and pat it dry.
- Dispense onto the palms or onto a cotton pad.
- Press it over the whole face, giving extra attention to the areas that break out.
- Let it absorb — it does not need to be rinsed or wiped.
- Follow with a light moisturiser if your routine includes one.
Frequency: Morning and evening, after cleansing.
Full Ingredients
Regulatory class: 医薬部外品 (Japanese quasi-drug), so actives are declared separately.

Cautions
- Contains ethanol. Do not use on broken, weeping or freshly exfoliated skin.
- Contains methylparaben. Avoid if you have a known paraben sensitivity.
- Stop using it if redness, swelling, itching or persistent stinging appears, and see a doctor if it does not settle.
- Avoid the eye area; rinse with plenty of water if it gets into the eyes.
- Acne that is painful, cystic, scarring or not improving needs a dermatologist. A quasi-drug toner is not a treatment for moderate or severe acne.
- Keep out of reach of children. Store away from direct sunlight and high heat.

FAQ
Does it contain fruit acids or grapefruit extract?
No. Our previous listing said both and neither is in Cow Brand's declaration. The declared botanicals are Centella asiatica and coix seed extract, and there is no AHA. If you were looking for an exfoliating acid toner, this is not one.
What makes it 'medicated'?
Two declared actives: isopropylmethylphenol, an antibacterial aimed at the bacteria involved in acne, and dipotassium glycyrrhizate, which addresses irritation. That combination is what earns the 医薬部外品 quasi-drug registration.
Is it really oil-free?
Yes — Cow Brand sells it as オイルフリー and no oil or ester emollient appears in the declaration. That is the point of the format for acne-prone skin.
Can I use it on my back or chest?
It is formulated and registered as a facial lotion. Nothing in the ingredients makes body use unsafe, but the maker's directions and the quasi-drug registration are for the face, and that is what we can tell you with confidence.
Does it sting?
It contains ethanol, so it can on freshly cleansed or already irritated skin. It also contains methylparaben, worth knowing if you avoid parabens.
