What it is
DUO Cleanse Serum Peel&Boost is a Japanese rinse-off cleansing serum, 90g, that cleanses, gently exfoliates, and preps skin in one step. Massaged onto dry skin for about a minute, it lifts makeup and dead-cell buildup with azelaic acid, then rinses clean with no double cleanse, leaving skin smooth and soft rather than tight.
Why it's different
It works as four steps in one: makeup remover, cleanser, gentle peel, and a booster that preps skin for what comes next.
Azelaic acid loosens dead-cell buildup for a mild daily peel, so texture refines without scrubbing or a separate exfoliant.
Human-type ceramides carried in liposomes condition the surface, so skin rinses soft instead of stripped.
Key ingredients
Azelaic acid: gives a gentle daily peel that refines texture
Human-type ceramides (liposome): condition so skin rinses soft, not stripped
How to use
1. Start with dry hands and a dry face.
2. Take an appropriate amount and spread it over the whole face.
3. Massage in small circles for about one minute.
4. Rinse thoroughly with lukewarm water. A separate cleanser is not required.
Use in place of your usual cleanse, daily or as preferred.

Frequently Asked Questions
Is this authentic?
Yes. We only buy from official retailers and directly from the brands here in Japan. Never resellers, never grey market stock.
We are beauty lovers too, so we know the worry, especially with something you are putting on your face. Authenticity is 100% guaranteed by us.
Can I use this every day instead of my regular cleanser?
Yes. It is designed to replace your usual cleanse, removing makeup and buildup while giving a mild peel. If you wear heavy or waterproof makeup, you can follow with a second cleanse, though it is not required for everyday wear.
Do I apply it to wet or dry skin?
Dry. Use it on dry hands and a dry face so it can bind to makeup and buildup, massage for about a minute, then rinse with lukewarm water. There is no need to emulsify with water first.
Is the peeling strong enough to irritate sensitive skin?
It is formulated as a gentle daily peel with azelaic acid and skin-conditioning ceramides, so most people can use it often. If your skin reacts easily, start a few times a week and rinse thoroughly, since residue can cause irritation.
What is the mini size for?
This set pairs a full 90g size with a 21g mini, so you can keep the large one at home and carry the small one for travel or the gym. Both are the same formula.
