SkinCeuticals - Serum 10

SkinCeuticals Serum 10 is a lightweight daily antioxidant serum with 10% pure vitamin C (L-ascorbic acid) and 0.2% ferulic acid. It is the entry point into the SkinCeuticals antioxidant range, formulated at a lower concentration for skin that is new to vitamin C or that has found stronger formulas irritating.

The benefits are the same in kind as the higher-strength serums: protection against environmental free radicals, improved radiance, more even tone, and softer-looking fine lines with continued use. The difference is tolerability.

Many patients use Serum 10 for several months and then step up to C E Ferulic or Phloretin CF once their skin has adjusted. Others simply stay with it, which is an entirely reasonable outcome; a serum used daily is worth more than a stronger one used occasionally.

1. Cleanse and dry your skin completely.
2. In the morning, apply 4 to 5 drops to your face, neck, and chest.
3. Press in and let it absorb for about 60 seconds.
4. Follow with moisturizer and a broad spectrum sunscreen.
5. Start every other morning for the first two weeks, then move to daily.

Store upright, away from heat and direct light.

10% L-Ascorbic Acid (Vitamin C): pure, bioavailable vitamin C at a concentration chosen for tolerability, providing free radical defense and collagen support.

0.2% Ferulic Acid: stabilizes the vitamin C and enhances its photoprotective effect.

Lightweight, Fast-Absorbing Base: layers cleanly under moisturizer and sunscreen.

• Provides daily antioxidant protection against environmental stress.
• Helps improve visible radiance and uneven tone.
• Softens the appearance of fine lines with continued use.
• Lower concentration is well suited to sensitive skin and first-time vitamin C users.
• Lightweight texture that absorbs quickly.
• Layers cleanly under moisturizer and sunscreen.

There is no advantage in starting at the strongest formula available. Patients who begin with 15% vitamin C on reactive skin frequently sting, get red, and stop, and a serum abandoned in week two has done nothing at all.

Our providers use Serum 10 as the on-ramp. Three months at 10% gives most skin time to adjust, after which stepping up to C E Ferulic or Phloretin CF is straightforward. It is also the right permanent choice for genuinely sensitive skin.

If you find even this concentration uncomfortable, a pH-neutral vitamin C derivative such as Alastin C Radical Defense may suit you better. Order it whenever you need it. We ship nationwide, and no appointment is required.
