SPF + Antioxidants
SPF + Antioxidants — a protective daytime pairing of broad-spectrum sunscreen, which blocks or absorbs UV radiation, with topical antioxidants like vitamin C or E, which help neutralize free radicals that sunscreen alone does not fully address. Together they offer more complete daytime defense against environmental damage.
Key points
- Sunscreen is the primary defense against UV rays, helping prevent sunburn, premature aging, and UV-related discoloration.
- Antioxidants help neutralize free radicals generated by UV and pollution, providing a complementary layer of protection.
- Because no sunscreen blocks 100 percent of radiation, layering antioxidants underneath can help reduce residual oxidative stress.
- Antioxidants support but do not replace sunscreen, which remains essential and should be reapplied as directed.
Frequently asked
Do antioxidants replace the need for sunscreen?
No, antioxidants complement sunscreen but cannot block UV radiation on their own. Broad-spectrum SPF remains the foundation of daytime protection.
How should I layer antioxidants and SPF?
Antioxidant serums like vitamin C are typically applied first, followed by moisturizer and then sunscreen as the final protective step. Allow each layer to settle before applying the next.
