Description

Obagi C10 Vitamin C Serum is the most popular entry in the Obagi C Series — a 10% pure ascorbic acid formula designed for those actively dealing with visible pores, uneven texture, and early dullness. Developed by Rohto Pharmaceutical, this Japan-domestic serum sits at the core of the Obagi C ladder and is widely recommended as the first step for anyone moving from beginner concentrations.

The Advanced C Control EX system drives ascorbic acid from the skin surface down through the stratum corneum, while Deep C Porter — powered by iris root extract — supports delivery to deeper skin layers. Signal Lock Complex provides multi-layer moisture reinforcement with yeast and centella extract, pairing the vitamin C actives with skin-calming and pore-refining support.

C10 is formulated at the same grapefruit-scented dropper format as the full Obagi C series. If you've already used C5 and adapted well, C10 is the natural next step. It can also be used as a long-term maintenance concentration by those who find C20 and C25 too intense for daily use.

Key Ingredients
  • Ascorbic Acid (Pure Vitamin C) — 10% concentration for brightening, pore smoothing, and antioxidant protection
  • Tocopherol (Vitamin E) — stabilises vitamin C and supports moisture retention
  • Iris Root Extract — Deep C Porter component; aids delivery of vitamin C into the stratum corneum
  • Centella Asiatica Extract — anti-inflammatory support, promotes collagen synthesis alongside vitamin C
  • Artichoke Leaf Extract — targets visible pore enlargement at a cellular signalling level

HOW TO USE
  1. Apply toner after cleansing to prep skin.
  2. Dispense 3–4 drops into your palm using the dropper.
  3. Press across the whole face, layering extra on pore-prone areas like the nose and forehead.
  4. Finish with emulsion or moisturiser to lock in moisture.
  5. Pro tip: Store in the refrigerator after opening to maintain vitamin C stability and extend freshness.

FAQ

How does C10 compare to C5 and C20?

C5 (5%) is for skin new to vitamin C or reactive skin. C10 (10%) is the core everyday potency — addresses pores, texture, and early dullness with good tolerability. C20 (20%) adds more intensity for those with established routines who want to target pigmentation more aggressively.

How long before I see results?

Skin texture and pore appearance typically show improvement within 4–6 weeks of consistent twice-daily use. Dullness and tone evenness may take longer depending on baseline skin condition.

Can I use C10 if I have sensitive skin?

C10 is tolerated by many people with moderately sensitive skin. If you experience persistent tingling or redness, start with C5 and build up gradually. Always apply on well-hydrated skin.

Is this the Japan-domestic version?

Yes. Sourced from Japanese drugstores including Matsumotokiyoshi, this is the same Japan-domestic formula available in Japan — not an export edition. TokyoShelf carries only domestically-sold formulas.
