Vitamin C serums have become a staple in skincare routines for their ability to brighten skin, reduce hyperpigmentation, and support collagen production. They also neutralise free radicals from UV light and pollution, helping to prevent premature ageing. However, not all formulas suit every skin type, especially those with sensitive or rosacea-prone skin.
Pharmacist and skincare expert Dr Sonal Chavda-Sitaram advises caution with L-ascorbic acid, the most common active form of vitamin C, as it can trigger inflammation in compromised skin barriers. She recommends lipid-soluble derivatives like tetrahexyldecyl ascorbate (THD ascorbate) for such individuals, as they penetrate deeply without irritation.
After testing 15 vitamin C serums over four months, the overall best pick is CeraVe Skin Renewing Vitamin C Serum. For budget-conscious shoppers, Elf Skin Brighten + Glow Vitamin C + E + Ferulic Serum is recommended. SkinCeuticals C E Ferulic Antioxidant Treatment excels in protection, while Indē Wild Vitamin C Sunrise Glow Serum targets hyperpigmentation. The best Korean option is Haruharu Wonder Centella 4% TXA Gel Serum.
Key factors in testing included texture, scent, skin feel, makeup compatibility, visible results, and value. Additional ingredients like vitamin E and ferulic acid, which boost UV protection, were also considered. Packaging is crucial, as L-ascorbic acid oxidises rapidly when exposed to light and air; airless pump bottles and stabilising antioxidants help maintain efficacy.
Vitamin C benefits all skin types through antioxidant protection, collagen synthesis, and brightening, but the form and concentration must match individual tolerance. Those with photo-aged skin are likely to see the most dramatic results.
