KISO Care Retinol Serum No. 035
Good to know before you add it.
Clinical-grade retinol from a Japanese pharmacy brand most of the region has never heard of. Not gentle. If you are new to retinol, start lower. If you have used Western retinols and found them either too harsh or too weak, this sits in a sweet spot Japanese formulators are particularly good at — high enough concentration to deliver real results, paired with a barrier-supportive base that prevents the worst of the irritation.
The most powerful product in the edit. The one I'd actively dissuade some readers from buying.
A high-concentration pure retinol serum from KISO Care, a Japanese pharmacy-style minimalist skincare line that most of this region has never heard of. Pure retinol stabilized in a squalane base — no fragrance, no fillers, no ceremony. Clinical-grade formulation in a 30ml dropper.
The honest assessment: this works. Real photodamage reduction after eight to twelve weeks of consistent use. The honest warning: it can be too much for skin that isn't ready. Western retinol routines tend to be slow and gentle. This one is direct.
What to expect: First two weeks — slight dryness, possible flaking. Weeks three to six — skin texture begins to refine, fine lines look softer. Weeks eight to twelve — visible reduction in photodamage, clearer overall complexion. Use only at night. Wear SPF daily — non-negotiable.
For: experienced retinol users, mature skin, photodamage, anyone who's built tolerance through gentler products. Not for: pregnancy or breastfeeding, retinol beginners, sensitive or compromised skin, anyone using other acids or strong actives without dermatologist guidance.
How to use: Cleanse and dry skin completely. Apply 2 to 3 drops to fingertips, press onto face. Avoid the eye area and lip line. Follow with moisturizer. Start with 2 nights per week. Build to every other night over 6 weeks. Never apply to damp skin — it amplifies the intensity. SPF 30+ every morning, mandatory.
