Description

Obagi C5 Vitamin C Serum is the entry point to Obagi's pharmaceutical-grade pure vitamin C ladder — formulated for anyone noticing the first signs of uneven texture, rough skin, or dull tone. This Japan-domestic formula is developed by Rohto Pharmaceutical and uses the same clinical Obagi C Series technology as higher concentrations, at a gentler 5% pure ascorbic acid level suited to vitamin C beginners or those with reactive skin.

The Advanced C Control EX system drives pure vitamin C from the skin surface down into the stratum corneum, working alongside vitamin E to support moisture retention and visibly smoother pores. Signal Lock Complex — a blend of iris root extract and yeast extract — reinforces hydration at multiple skin layers, leaving skin noticeably more even and luminous with consistent use.

All four Obagi C concentrations share the same core delivery technology. C5 is the ideal starting point before stepping up the ladder as your skin adapts.

Key Ingredients
  • Ascorbic Acid (Pure Vitamin C) — 5% pure vitamin C for brightening, pore smoothing, and antioxidant protection
  • Tocopherol (Vitamin E) — supports moisture retention and enhances vitamin C stability
  • Iris Root Extract — key component of Deep C Porter technology, aids vitamin C delivery to deeper skin layers
  • Centella Asiatica Extract — calms inflammation and supports collagen synthesis alongside vitamin C
  • Artichoke Leaf Extract — research-backed ingredient targeting visibly enlarged pores

HOW TO USE
  1. After washing your face, apply toner to prep and hydrate skin.
  2. Dispense 3–4 drops into your palm using the dropper.
  3. Press gently across the entire face, focusing on dull or uneven areas.
  4. Follow with emulsion or moisturiser to seal in hydration.
  5. Pro tip: If tingling occurs, apply after your emulsion step rather than before — it reduces sensation without reducing efficacy.

FAQ

How is C5 different from C10, C20, and C25?

The number refers to pure vitamin C concentration. C5 is 5%, C10 is 10%, C20 is 20%, and C25 Neo is 25%. Higher concentrations address a broader range of concerns — pores, texture, dark spots, firmness — but may feel more intense on sensitive skin. C5 is the gentlest starting point.

Will this cause redness or irritation?

A brief tingling sensation on first use is common and typically passes quickly. If redness persists or worsens, discontinue use. Applying over a toner-hydrated skin base helps minimise the sensation. C5 is the lowest-irritation entry in the Obagi C lineup.

When should I apply it in my routine?

Apply morning and evening after toner, before emulsion or moisturiser. On dry-feeling days, you can layer it after your emulsion for a gentler delivery.

Is this the Japan-domestic version?

Yes. This is the Japan-domestic formula sourced directly from Japanese drugstores including Matsumotokiyoshi. TokyoShelf carries only the version sold in Japan, not an export reformulation.
