Do You Actually Need Vitamin C Serum? A Dermatologist Explains
Highlights (7)
A board-certified dermatologist explains the potential antioxidant, anti-aging, and depigmenting benefits of topical vitamin C. Although clinical studies are encouraging, the evidence is limited and does not show that vitamin C is superior to better-established options. Sunscreen and topical retinoids should take priority, while formulation, irritation, and cost are important limitations.
- Topical vitamin C may improve wrinkles, texture, and pigmentation, but the evidence is limited.
- Sunscreen and topical retinoids have stronger research support.
- Choosing ascorbic acid does not guarantee stability or effective skin penetration.
- Irritation may worsen hyperpigmentation, especially for deeper skin tones or rosacea-prone skin.
- Vitamin C serum is optional and can be expensive.
