Why Use a Vitamin C Serum? Dermatologist Insights
Why the Best Vitamin C Serum is Essential for Your Skincare Routine
Vitamin C is a potent antioxidant that neutralizes free radicals—unstable molecules generated by UV rays, pollution, and other environmental stressors that accelerates skin aging.
According to Harley Street dermatologist Dr. Ariel Haus, vitamin C plays a crucial role in collagen synthesis, which improves skin firmness and reduces fine lines.
It also helps regulate melanin production, making it highly effective against hyperpigmentation and dullness.
Board-certified dermatologist Dr. Diane Madfes emphasizes that vitamin C serums not only brighten the complexion but also protect skin from environmental damage and promote a smoother texture.
 However, vitamin C can sometimes irritate sensitive or acne-prone skin, so it’s important to introduce it gradually and choose a formulation suited to your skin type.
What to Look for in a Vitamin C Serum?
When selecting a vitamin C serum, dermatologists recommend focusing on:
Type of Vitamin C: The most researched and effective form is L-ascorbic acid, but it can be irritating for sensitive skin. Alternatives like sodium ascorbyl phosphate or tetrahexyldecyl ascorbate (THD) are gentler.
Concentration: Beginners should start with concentrations under 10%, gradually increasing to 15-20% as tolerated.
Additional Ingredients: Look for serums with vitamin E and ferulic acid, which stabilize vitamin C and enhance its antioxidant effects.
Packaging: Vitamin C oxidizes quickly when exposed to air and light, so opt for serums in dark, airtight bottles to maintain potency.
Skin Compatibility: Sensitive skin types should choose serums that are fragrance-free and formulated to minimize irritation.
