Antioxidants are your skin's daytime defense team, the ingredients that help neutralize the invisible stress your skin takes on every time it meets sun and pollution. They will not replace sunscreen, but paired with it they are one of the most worthwhile additions to a morning routine.
Free Radicals and Oxidative Stress
Every day, sun exposure and pollution generate unstable molecules called free radicals. These molecules are missing an electron, so they grab one from healthy skin cells, and that chain reaction, known as oxidative stress, damages collagen and other structures over time. It is a major driver of the visible signs of aging. Antioxidants are the counterweight: they donate an electron to neutralize free radicals before they can do their damage.
What Antioxidants Do for Skin
By defusing free radicals, topical antioxidants help protect the skin's structure and support a healthier, more even-looking complexion. Think of them as prevention. Sunscreen blocks and absorbs UV, while antioxidants mop up the reactive molecules that still form, so the two work best as a pair rather than a substitution.
The Key Antioxidants to Know
- Vitamin C is one of the most studied, valued for supporting a brighter, more even complexion and defending against environmental stress.
- Vitamin E works alongside Vitamin C and helps support the skin barrier.
- Niacinamide supports the barrier and a more even-looking tone.
- Plant extracts such as licorice and green tea add further antioxidant support.
Why Vitamin C Leads the Pack
Among antioxidants, Vitamin C is the one most people start with, and for good reason. Research shows it supports the look of firmer, brighter, more even skin while helping defend against daily environmental stress. For a deeper look, see our complete guide to Vitamin C in skincare.
InviCible Primer+™, developed by Dr. Minas Chrysopoulo, Board-Certified Reconstructive Plastic Surgeon, is built around 17% Stabilized Vitamin C, paired with the ProBiosyn-4™ complex, so a single morning step delivers antioxidant defense, light hydration, and a smooth base for makeup.
How to Use Antioxidants
Antioxidants are a morning ingredient. Apply them after cleansing and before sunscreen, so they can work underneath your SPF throughout the day when sun and pollution exposure are highest. A little goes a long way, and consistency matters more than quantity.
Your Antioxidant Morning Routine
- Cleanse. Start with a gentle cleanser on a fresh face.
- Apply your antioxidant. Smooth on a pea-sized amount of Primer+™ with 17% Stabilized Vitamin C.
- Moisturize if needed. Add a light moisturizer for extra hydration.
- Finish with SPF. Layer a broad-spectrum SPF 30 or higher over your antioxidant every morning.

Can antioxidants replace sunscreen?
No. Sunscreen blocks and absorbs UV, while antioxidants mop up the reactive molecules that still form. They work best as a pair, with the antioxidant applied first and sunscreen layered over it.
Which antioxidant is best to start with?
Vitamin C is the one most people start with. It is among the most studied, supporting a brighter, more even complexion while helping defend against daily environmental stress.
When should I apply antioxidants?
Antioxidants are a morning ingredient. Apply them after cleansing and before sunscreen so they can work underneath your SPF during the day, when sun and pollution exposure are highest.
What are free radicals?
Free radicals are unstable molecules generated by sun exposure and pollution. Because they are missing an electron, they grab one from healthy skin cells, and that chain reaction, called oxidative stress, damages collagen and other structures over time.
