What Do Antioxidants Do for Skin?
Let’s start with the basics: What do antioxidants do? Antioxidant skincare plays a crucial role in protecting the skin from damage caused by free radicals—unstable molecules generated by UV rays, pollution, and lifestyle factors like smoking and alcohol consumption.
Without antioxidant defence, free radicals contribute to premature ageing, including fine lines, wrinkles, discolouration, and loss of firmness. Incorporating antioxidant skincare into your daily routine can provide both immediate and long-term benefits.
Key Antioxidant Benefits for Skin:
- Neutralise Free Radicals – Help minimise oxidative stress and prevent damage to skin cells.
- Reduce Visible Signs of Ageing – Improve the appearance of fine lines, wrinkles, and skin laxity.
- Enhance Skin Radiance – Promote a more even skin tone and reduce discoloration.
- Boost Environmental Protection – Defend against UV rays, infrared radiation (IRA), and pollution.
- Support Skin’s Natural Repair Process – Strengthen the skin barrier and promote resilience.
SkinCeuticals has dedicated decades to advancing antioxidant skincare science, ensuring the most effective formulations. Our research has identified L-ascorbic acid—the purest and most studied form of vitamin C. This key ingredient provides superior defence against environmental damage while visibly improving signs of ageing, such as wrinkles and discolouration.
Daily use of a high-quality antioxidant serum can be a game-changer for maintaining healthy, youthful-looking skin. Discover SkinCeuticals Antioxidant Serums
How to Incorporate Antioxidant Protection Into Your Skincare Regimen
Morning and evening skincare routines offer opportunities to help shield the skin from environmental damage. SkinCeuticals offers several vitamin C serum options that provide daytime protection against free radicals.

C E Ferulic
This award-winning combination antioxidant features 15% pure vitamin C (L-ascorbic acid), 1% vitamin E (alpha tocopherol), and 0.5% ferulic acid for proven environmental protection and improvement in the appearance of photodamage, fine lines and wrinkles, loss of firmness, and overall skin brightness.

Phloretin CF
Formulated with 10% pure vitamin C (L-ascorbic acid), 2% phloretin, and 0.5% ferulic acid, this synergistic antioxidant blend has been shown to improve the appearance of fine lines, discoloration, and uneven skin tone.

Silymarin CF
Designed specifically for oily and acne-prone skin, this formula features 0.5% silymarin (milk thistle extract), 15% vitamin C (L-ascorbic acid), 0.5% ferulic acid, and 0.5% salicylic acid to help prevent oil oxidation that can lead to breakouts and protect against environmental damage that contributes to visible signs of ageing.

Resveratrol B E
Nighttime offers an additional chance to neutralise free radicals. Resveratrol B E is a first-of-its-kind overnight treatment combining 1% pure resveratrol, 0.5% baicalin, and 1% vitamin E to support the skin’s natural antioxidant defenses while enhancing the appearance of radiance and the feeling of skin firmness.
These day and night antioxidants for skin protection are appropriate for daily use and are formulated to work in synergy with other SkinCeuticals products for optimal results. For comprehensive environmental protection, it’s best to use antioxidant skin care in conjunction with a broad-spectrum sunscreen. SkinCeuticals offers several advanced sun-protection options for all skin types, including formulations that are designed to improve the appearance of discolouration and provide effective UV protection for those with active lifestyles.
SkinCeuticals corrective serums are formulated to address specific skin concerns while further customising and enhancing any skincare regimen.

When to Use Antioxidants in Skincare
We recommend using antioxidants in your skincare routine daily, ideally in the morning after cleansing and before applying sunscreen. This helps protect against environmental damage from UV rays, pollution, and free radicals throughout the day. Antioxidants like vitamin C work best when layered under SPF for enhanced defence.
Some antioxidant serums can also be used at night to support skin repair and combat oxidative stress accumulated during the day. Consistent use improves skin health and reduces signs of ageing.
Before applying an antioxidant serum, cleanse your skin to remove impurities and follow with a toner if desired. After allowing the serum to absorb into the skin, apply a moisturiser to lock in hydration and finish with sunscreen in the morning for added protection against environmental damage.
