From the variety of formulations, strengths, and everything in between, it can be hard knowing where to start when buying beginner Vitamin C serums. Many users have trouble deciding on the right percentage, be it 10%, 20% or more, which makes it very challenging to select supplement products for an effective skincare routine. Skincare experts will often say that 10% Vitamin C is the best entry level percentage, as it has the capability of providing brightening and antioxidant benefits, but is still low enough for most beginners’ sensitive skincare.
If you are expanding your skincare through the Skin Deva UK or this is your first antioxidant serum, we compiled this guide on the 10% Vitamin C recommendation, and the best way to incorporate Vitamin C into your routine and what you can realistically expect as benefits from regular use.
Why Beginners Should Start With a 10% Vitamin C Serum
Having the correct concentration from the beginning can help ensure your first Vitamin C Serum is an enjoyable experience. Rather than jumping straight to the highest percentage, starting with Vitamin C at 10% will help adapt your skin, while still providing plenty of benefits.

Gentle Yet Effective
Vitamin C Serums are great for brightening your skin and improving uneven skin tones. The Vitamin C at 10% is perfect for beginners in the UK. It provides skin users with daily antioxidants and protects against skin irritations that other Vitamin C Serums at higher concentrations provide. For most new users of Vitamin C, it provides them with results that they can see without shocking their skin too much.
Builds Skin Tolerance
Gradually introducing Vitamin C to your skincare routine allows your skin to get accustomed to the ingredient and gives you the option to work your way up to more concentrated Vitamin C products. Gradual incorporation increases the confidence you have in your routine and decreases the likelihood of skin sensitivity. A 10% formula is widely considered the best starter vitamin C serum, as it is a good introductory option to vitamin C for progressive antioxidant skincare for the majority of people.
Why Not Start With a 20% Vitamin C Serum?
Although it may feel like starting with a 20% Vitamin C serum is the best option, stronger does not necessarily mean better when you are a beginner to a certain ingredient. A 20% Vitamin C serum makes the addition of this active ingredient to your routine more likely to cause irritation, dryness and sensitivity. Work your way up to a 20% serum and build your tolerance if your specific skincare needs and goals require a more concentrated option.
