What it is
Business-Use Hydroquinone is a 10g professional-strength solution with 5 percent hydroquinone, made with a non-heated process because hydroquinone is heat-sensitive. Applied to dark spots at night, it targets the look of stubborn spots and uneven tone. It is a focused spot-care step for anyone who would otherwise cover spots with concealer.
Why it's different
A professional-strength 5 percent hydroquinone concentration for focused spot care.
A non-heated process helps keep the heat-sensitive hydroquinone stable.
Targets the look of stubborn dark spots and uneven tone.
How to use
1. At night, after cleansing, dab 1 to 2 drops onto the dark spots.
2. Follow with your usual skincare.
3. Use at night only, and always apply sunscreen the next day. Patch test first.

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.
How and when should I use it?
Use it at night after cleansing, dabbing 1 to 2 drops only onto dark spots, then continue your usual skincare. Always wear sunscreen the next day.
Do I need a patch test?
Yes. Because this is a strong 5 percent hydroquinone solution, patch test first, avoid broken or irritated skin, and stop if you notice irritation.
Why is sunscreen essential with it?
Hydroquinone can make skin more sensitive to sunlight, so daily sunscreen is essential to protect skin and keep results from reversing.
Can I use it all over my face?
No. It is a targeted spot treatment. Apply only to the dark spots you want to treat, not across the whole face.
