Vitamin C needs no introduction in the world of skincare! It is one of the most well-researched, proven and powerful ingredients.
Vitamin C is an antioxidant superstar for your skin that does it all— stimulates collagen production, improves uneven skin tone & texture, fades dark spots, hyperpigmentation and acne scars while also protecting skin against harmful free radicals (generated from sun exposure, pollution or smoking) which can lead to premature aging.
In short, this anti-aging power player can do all kinds of wonderful things to brighten and firm your skin at virtually any age, whether you are 25 or 50!
As you know, there’s no shortage of vitamin C serums in the market and they don’t always come cheap. So, how to choose the best affordable vitamin C serum that gives you the best bang for your buck?
How to Choose the Best Vitamin C Serum
One of the most important things to look for when choosing a vitamin C serum is that the product is packaged in an opaque or dark-colored bottle or tube to keep Vitamin C stable (that’s because pure Vitamin C oxidizes very easily when exposed to light and air)
Also, watch the color of your vitamin C serum. It should be very light – almost clear. If it starts to darken or turn brown/yellowish, that means it has degraded/oxidized and should not be used. To prevent that, it’s important to store vitamin C serum in a cool, dark area (even better if you keep it in the fridge) and close the lid tightly immediately after use.
Personally, I like to use a Vitamin C serum that contains pure L-ascorbic acid (Vitamin C in its most efficient form) between a concentration of 10-20%. If you are new to Vitamin C, it’s best to start with a 10-15% concentration and then gradually move up to 20%.
There is a great deal of evidence showing that combining Vitamin C with other potent antioxidants like Ferulic acid and vitamin E help stabilize pure Vitamin C and increase its efficacy. So, a well-formulated serum should also contain these beneficial ingredients that work synergistically with vitamin C to enhance its antioxidant power.
Also, did you know that a good Vitamin C serum (with pure ascorbic acid) has to be formulated at the right pH to work?! Vitamin C serum needs to be between a pH range of 2.5-3.5 in order to be most effective and absorb well into your skin. All of the serums listed below meet this criteria!
Nowadays, there are plenty of Vitamin C serums formulated with Vitamin C derivatives like — Tetrahexyldecyl Ascorbate, Sodium Ascorbyl Phosphate, 3-O-ethyl ascorbic acid, Magnesium Ascorbyl Phosphate, Ascorbyl Palmitate — but not all of them are equal in terms of stability and absorption rate. These derivative forms are usually more stable (don’t oxidize as easily) and promise to provide great results, but there hasn’t been enough research yet to support and prove their effectiveness as much as pure ascorbic acid. That said, these Vitamin C derivates can be a better option for those with sensitive skin type (more on that at the end of this article)
Pro tip: It’s best to use Vitamin C serum under your sunscreen every morning. Vitamin C boosts the UV protection of your sunscreen making it more effective. But remember, Vitamin C serum is NOT a substitute for sunscreen…it just helps skin better withstand sun exposure.
Best Affordable Vitamin C Serums
In this post, I have listed some of the most effective and affordable Vitamin C serums that really work. All of these serums have a cosmetically elegant, lightweight texture that’s suitable for all skin types. Not to mention, they are all formulated at the correct ph for best absorption.
