PROFESSIONAL-C® Serum 10% FAQ's
Introducing a high-strength antioxidant into your routine can raise important questions particularly for those with sensitive or reactive skin. Below, we answer the most common queries about Obagi PROFESSIONAL-C® Serum 10% to help you use the product confidently and effectively within your regimen.
What does Obagi PROFESSIONAL-C® Serum 10% do for the skin?
This serum delivers targeted antioxidant protection while addressing multiple early ageing concerns. It helps brighten dull skin, refine uneven tone, and defend against oxidative stress caused by UV exposure and pollution. Over time, it also supports collagen function, improving skin firmness and reducing the appearance of fine lines.
Is 10% Vitamin C strong enough to deliver results?
Yes. A 10% concentration of L-Ascorbic Acid is clinically effective while being more tolerable for dry or sensitive skin. It provides antioxidant defence and brightening benefits without the higher irritation risk sometimes associated with stronger concentrations such as 15% or 20%.
Can sensitive skin tolerate this serum?
This formulation is specifically designed for sensitive and dryness-prone skin types. While mild tingling can occur initially, most users tolerate the serum well. Gradual introduction. starting every other morning can further enhance tolerance if required.
When should I apply Vitamin C in my routine?
Vitamin C is best applied in the morning after cleansing and toning but before moisturiser and SPF. This placement allows it to provide daytime antioxidant protection against environmental aggressors such as UV radiation and pollution.
Why is SPF essential when using Vitamin C?
Although Vitamin C enhances photoprotection, it is not a substitute for sunscreen. Pairing this serum with daily SPF maximises defence against premature ageing, pigmentation, and collagen breakdown caused by UV exposure.
