Formulated at the precise concentration proven to deliver maximum amounts of antioxidant vitamin C to the skin, Skinceuticals Serum 20 contains 20% pure stabilized L-ascorbic acid to:

• increase collagen and elastin production for firmer skin and tightened pores;
• prevent premature signs of aging;
• help protect against damaging UVA/UVB rays when used with a true broad spectrum sunscreen.

This antioxidant treatment is lightweight, fast-absorbing, and suitable for all skin types and conditions excluding wide-spread active acne (these patients are recommended C + AHA or Jan Marini C-ESTA Oil Control Serum instead).

• Ideal for normal to oily and normal to dry skin. Patients with significantly dry-prone skin will prefer C E Ferulic, which provides additional antioxidant benefits.

Skinceuticals Serum 20 Benefits:

• Proven to deliver the highest levels of vitamin C to the skin — for reasons unknown, concentrations above 20% actually reduce absorption:
  
• Antioxidant and nutritive effects reduce the appearance of fine lines and wrinkles, neutralise free radicals to prevent oxidation, provide photoprotection in addition to that brought by sunscreens, and stimulate collagen synthesis;
• Once absorbed, can’t be washed or rubbed off, remaining protective for up to four days;
• Dramatically improves skin tone and elasticity.

Further information including clinical studies and a range of before/after pictures over one year of antioxidant + broad spectrum sunscreen treatment are available by post.
