About this product
Obagi C5 Serum is the entry point into Rohto's Obagi C Serum line, a pure vitamin C serum formulated for those concerned about rough, uneven texture. It's positioned as the mildest concentration in the C5/C10/C20/C25 lineup, making it a common starting point for first-time vitamin C users or those with more sensitive skin.
How to use
- Morning and evening, after cleansing and toning, use the dropper to dispense 3–4 drops into your palm.
- Smooth evenly over the face, layering extra product onto areas of concern.
- If your skin feels dry, apply after your lotion/toner step rather than directly after cleansing.
Ingredients
- Ascorbic Acid (Pure Vitamin C) — the core active across the Obagi C Serum line, supporting a smoother, more refined-looking complexion.
- Tocopherol (Vitamin E) — an antioxidant that complements vitamin C in the formula.
- Signal Lock Complex — Obagi's proprietary conditioning complex included across the C5/C10/C20 serums.
FAQ
Is C5 the mildest in the Obagi C Serum lineup?
Yes — C5 is formulated as the lightest option among Obagi's C5/C10/C20/C25 serums, and is often recommended for beginners or more sensitive skin.
Will it feel like tingling or irritation?
Some users notice mild tingling when starting a vitamin C serum; if this bothers you, apply after your toner rather than directly on cleansed skin.
Is this a medical treatment?
No — it's a cosmetic vitamin C serum for everyday skincare, not a medicated or medical product.
