23 Best Vitamin C Serums of 2023 Recommended by Dermatologists

Vitamin C is available in a number of concentrations, from 5% through to 30%, and it depends on your skin type as to the potency you should go for. Generally speaking, we'd recommend products that contain between 10-15% potency as being the most universal.

Vitamin C is highly effective in its pure form, but it's notoriously unstable due to the fact that it can reduce in effectiveness with exposure to oxygen, light, water and high pH. This makes it hard to formulate. With that in mind, while it is a hero ingredient, its properties are difficult to stabilise — so if you can, opt for something a little more expensive and something housed in a darker bottle (they'll block light so it doesn’t oxidize and keep your product working well for longer).

Consider your skin type, too. If you have oily skin, look for "ascorbic acid" on the label. If you have dry skin, look for vitamin C serums which also include moisturising ingredients like (everyone's favourite) hyaluronic acid. If you have acne-prone skin, salicylic acid is tough on blemishes. Make a beeline for the La Roche Posay Pure Vitamin C Serum.
