Is Obagi Japanese? Obagi Japan vs Obagi Medical
Obagi can mean two different skincare ranges. The Japanese range is sold by Rohto; Obagi Medical is the US range with Professional-C, Hydrate, ELASTIderm and Nu-Cil. They share a name, but their products are not interchangeable.
If a Japanese shopping list mentions Obagi C10 or C25 Serum NEO, it means Rohto’s range. If you are looking at a blue Professional-C bottle, Hydrate cream or Nu-Cil serum, use our Obagi Medical product guide.

Rohto records the Japanese Obagi launch in 2001. That is why the name comes up in Japanese drugstore recommendations. It does not mean every Obagi product you find in an American store is the Japanese formula.
Which Japanese Obagi serum should you compare?
Rohto’s C serum range contains ascorbic acid, and the brand says concentration increases from C5 through C25. Choose the product by its purpose and your skin’s tolerance.
- C5: the simpler starting point in the range, positioned around texture.
- C10: worth comparing when the appearance of pores is your main concern.
- C20: adds a broader focus on texture and dullness.
- C25 Serum NEO: the range’s highest vitamin C concentration, with additional positioning around firmness and fine lines caused by dryness.
These serums contain fragrance. A lower number does not make a product fragrance free or guarantee that sensitive skin will tolerate it.
Already happy with Melano CC? Keep it on your shortlist. You do not need to move up to Obagi just because the range offers a higher concentration.
Looking for the US vitamin C serum instead?
Professional-C makes sense to compare if you specifically want Obagi Medical’s stated 10%, 15% or 20% strength. Start with the three-strength comparison rather than translating a Japanese C10 recommendation directly.
The lowest Professional-C strength
Obagi Professional-C Serum 10%
Choose 10% if you want Obagi Medical’s lowest L-ascorbic acid concentration. The brand positions it for dry or sensitive skin, but it still contains fragrance and can sting.
A lower percentage is not a guarantee that reactive skin will tolerate it.

The Obagi C enzyme wash is a cleanser, not a serum. If that is the product you saw in a shopping video, compare it with the other Japanese enzyme powder cleansers.
Obagi X is another Japanese range, with products focused on moisture and firmer looking skin. Its lotion and mousse wash fill different routine steps.

Common questions
Is Obagi Japanese?
The Obagi range sold by Rohto in Japan is Japanese. Obagi Medical is a different US skincare range. Check the full product name before treating a recommendation as interchangeable.
Is Japanese Obagi C10 the same as Professional-C 10%?
No. C10 belongs to Rohto’s Japanese range; Professional-C 10% belongs to Obagi Medical. Similar names do not mean the formulas are the same.
Where should I buy Obagi in Japan?
Use Rohto’s official Obagi store locator to find participating shops. Individual stores can confirm their current stock.
Should I buy the highest Obagi C serum?
Not automatically. Choose the formula and routine you can use comfortably. Rohto’s range increases in vitamin C concentration from C5 through C25, but higher concentration is not a promise of better tolerance or faster results.
