Questions about Izumi
Straight answers, no marketing. If yours is not here, write to [email protected].
Does Izumi contain retinol?
No. Its renewal actives are copper tripeptide-1 and a low level of lactic acid, supported by resveratrol, niacinamide and multi-weight hyaluronic acid. That makes it a gentler option than retinoids for sensitive skin.
What results did the study show?
In an independent 30-day study (The Good Face Project, March 2025, 46 participants) 93% said the serum is gentle on their skin, 87% said their skin appears more glowing and 76% noticed their skin appearing plumper. No adverse events were reported.
Can I use it together with Kido?
Yes, both at night: cleanse with Kirei, apply Kido, then Izumi, and finish with Iro. That is the Brightening + Anti-Aging routine.
Does it contain fragrance?
No. Izumi is fragrance-free and essential-oil-free.
Serum or cream? How much do I use?
Izumi is a serum with a rich, creamy texture. Apply 1–2 pumps to clean skin at night and follow with Iro to lock in moisture.
Is it safe during pregnancy?
Izumi contains copper peptide and lactic acid. These are generally considered compatible with pregnancy at cosmetic levels, but please confirm with your doctor.
