From eyelash serums to hyaluronic acid serums, there are a whole lot of serums flooding the shelves of beauty stores and drugstores. But if you only have room in your routine for one, let it be a vitamin C serum.

Vitamin C is a powerful antioxidant that brightens your complexion by blocking excess pigment creation, fights fine lines by stimulating collagen, and protects your skin from damaging free radicals and other environmental stressors. The downside? Compared to most products, it often costs more per ounce.

Once you begin to see the results of a good vitamin C serum, however, you can use less foundation, less concealer, and less highlighter, which ultimately saves you money. Ahead, we’ll tell you what to look out for in vitamin C serums and the best vitamin C serums to invest in.

What to look for in vitamin C serums

vitamin c serums what to look for

There are several forms of vitamin C, and not all are created equal. Check the serum’s label for L-ascorbic acid, which is considered to be one of the best forms of vitamin C for the skin. Better yet, tetrahexyldecyl ascorbate, which is a stable, oil-soluble form of vitamin C.

If you can’t find those two in the ingredients list of your vitamin C serum, look for these useful forms of vitamin C:

  • Ascorbic acid
  • Ascorbic acid sulfate
  • Ascorbyl 6 palmitate
  • Ascorbyl glucoside
  • Disodium isostearyl 2-0 L-ascorbyl phosphate (VCP-IS-Na)
  • Magnesium ascorbyl phosphate
  • Sodium ascorbyl phosphate
  • Tetrahexyldecyl ascorbate

Since vitamin C is also notoriously unstable, especially when it’s exposed to air and light, it’s best to pick a formula that comes in an airtight pump or opaque bottle. To extend its shelf life, you should also remember to store it in a cool, dark place, away from direct sunlight.

You may associate vitamin C with a bright orange colour, but that doesn’t always apply to the best vitamin C serums. Active vitamin C solutions should be almost colourless or bear a champagne tint. However, during the manufacturing process, other ingredients may be whisked in, which can sometimes darken the colour of the vitamin C serum. So even though it looks yellow or orange, it can still contain active vitamin C.

How to use vitamin C serums in your routine

vitamin c serums how to use

In general, it’s best to cleanse and tone before applying a vitamin C serum on your face. You’ll only need a few drops of serum, which you should pat gently on your skin with your fingertips. After that, you can finish up your routine with a moisturiser and sunscreen. Vitamin C serums can be used once or twice a day, morning and/or night.

To help you cut through the clutter and make it a little less overwhelming for you, we’ve picked out the best vitamin C serums on the market. These are suitable for a wide range of skin types and there’s one to fit every budget.
