Vitamin C: The Classic

Vitamin C (L-ascorbic acid) has been a staple in the skincare world for decades. This water-soluble antioxidant is abundant in citrus fruits, berries, and other plant-based foods. When applied topically, it helps to:

Neutralize free radicals and reduce oxidative stress
Boost collagen production and improve skin elasticity
Enhance skin brightness and reduce the appearance of fine lines and wrinkles
Reduce hyperpigmentation and dark spots

Azelaic Acid: The Newcomer

Azelaic acid, on the other hand, is a tyrosinase inhibitor derived from wheat, rye, or barley. It has been shown to:

Inhibit melanin production, reducing unwanted dark spots and hyperpigmentation
Reduce inflammation and soothe sensitive skin
Improve skin texture and tone
Enhance skin clarity and even out skin tone

Head-to-Head Comparison

While both ingredients have their unique benefits, some key differences set them apart. Vitamin C is more effective at neutralizing free radicals, boosting collagen production, and addressing fine lines and wrinkles. Azelaic acid, on the other hand, is more effective at inhibiting melanin production and addressing hyperpigmentation.

In our comparison, Vitamin C takes the lead in addressing signs of aging, while Azelaic acid shines in tackling hyperpigmentation. Ultimately, the best approach may be to combine both ingredients for a comprehensive skincare routine.
