Best Vitamin C Serums For All Budgets And Skin Types
When it comes to glowing, healthy skin, Vitamin C is one of the most researched and results-driven ingredients in skincare. But here’s the truth: not all Vitamin C serums are created equal. From the best tried-and-trusted formulas to the newest innovations, this guide will walk you through exactly what Vitamin C can (and can’t) do for your skin.
Vitamin C is well-documented for its ability to brighten, even skin tone, boost collagen, and protect against free radical damage, but the wrong formula can leave you disappointed. Stability is key. Ever wondered why your Vitamin C serum seems to lose its punch before you’ve finished the bottle? You’re not imagining it; many forms of Vitamin C quickly break down when exposed to air, light, or heat, making them far less effective over time.
Another reason Vitamin C is a must-have? When layered under sunscreen, it doesn’t just protect your skin from environmental damage; it boosts your SPF’s effectiveness, giving your skin an extra layer of defence against UV-induced ageing.
In this blog, I will cover the most frequently asked questions, I’ll break down the most effective Vitamin C serums worth investing in, the science behind their formulations, and how to use them correctly to get the best results for your skin.
What does Vitamin C do for the skin?
Vitamin C has many benefits, and some are very much overclaimed. First and foremost, vitamin C is an antioxidant, which means it can neutralise and help stop free radicals from damaging skin cells. This process is known as oxidative stress. If you think of an apple browning, this is oxidation, and when the skin is attacked by environmental aggressions like UV exposure and pollution, the same thing happens. Fortunately, the skin doesn't change colour; however, it's damaging to the skin cells. Vitamin C will brighten the complexion and help with collagen production. I will caveat this by saying that to make collagen, you need vitamin C, it's a partner in the production, it doesn't solely stimulate collagen production as so many claims say.
Which form of Vitamin C is most effective or stable?
The most effective vitamin C is the one you can tolerate. Vitamin C isn't for everyone. Whilst ascorbic acid is the purest form of vitamin C, it's the one that can cause the most irritation. Derivatives tend to be the best place to start, and allow you to start slowly.
How do I incorporate Vitamin C into my routine—and when should I use it?
Typically, Vitamin C is applied immediately after cleansing and toning. If you are applying an essence and or mists, I would apply this also before your vitamin C serum too.
Can you use Vitamin C with retinol?
Layering Vitamin C needs to be approached with caution; I wouldn't recommend layering vitamin C with retinols. The best routine is Vitamin C in the morning and retinol at night.
What concentration of Vitamin C is best, and is higher always better?
Whilst the best percentage is the best your skin can tolerate, and no two skins are alike, I would always suggest that when it comes to vitamin C, you should start low and slow. Around 10-15 % is meant to be the optimum level for your skin.
Will Vitamin C help with dark spots and hyperpigmentation?
As a skincare expert, this is where I struggle with marketing claims. Vitamin C will help brighten the skin, but alone, it won't be able to lighten or fade hyperpigmentation. Vitamin C does help to inhibit melanin formation through disrupting the tyrosinase activity (the enzyme responsible for communicating with the melanocyte cell. However, deeper or stubborn pigment often responds better to a more 360-degree approach
