Here are the 7 best vitamin c serums, according to reddit users.

Vitamin C Serum Benefits

This powerful antioxidant boasts a host of benefits when applied topically to the surface of the skin. If you need further convincing to try this wonder vitamin on your skin, check out this list of benefits:

  • Helps Hydrate Skin - Vitamin C has a hydrating effect on the skin as it reduces transepidermal water loss so that it is able to retain moisture more efficiently. Your skin will begin to feel dewy and supple with the inclusion of a vitamin C serum into your regimen.
  • Helps Fade Hyperpigmentation (Dark Spots) - Although the use of a vitamin C serum will not completely eliminate signs of hyperpigmentation, it can have a drastic effect on its visible appearance. By impeding the production of melatonin, a vitamin C serum will fade dark spots and lead to a more even complexion. 
  • Boosts Collagen Production - One of the primary benefits of using vitamin C on the skin is that it will begin to increase the body's production of collagen. With more collagen production, the skin will firm up and become more elastic and less prone to sagging.
  • Mitigates Sun Damage - Because vitamin C is rich in antioxidants, it offers protection against free radicals. It is these free radicals that cause sun damage to the skin. 
  • Reduces the Appearance of Under-eye Circles - Another side benefit of daily use of a vitamin C serum is that it may reduce the appearance of those undesirable circles under the eyes. By lessening the discoloration of the skin, the skin under the eye will begin to take on a more natural color and glow.

How to Use a Vitamin C Serum

Incorporating a vitamin c serum into your skincare routine is easy, here's how:

Step 1: Cleanse and Exfoliate Your Skin

Cleanse your skin with a gentle facial cleanser. Next, follow-up a chemical exfoliant. This will ensure that the skin is ready to receive the benefits of the serum. Be sure to let the skin properly dry before applying the serum so that it is efficiently absorbed.

Step 2: Apply a Few Drops of Serum To Your Palm

Next, apply a few drops of the serum into your hand. Remember that a little goes a long way when it comes to the powerful benefits of a vitamin C serum. Use your fingertips of the opposite hand to gently apply the serum onto your entire face. Do not apply the serum onto a cotton pad or washcloth first. This will only cause the serum to absorb into the material and waste too much of the product. You will see the most benefit and experience the least amount of waste if you apply it directly to the skin.

Step 3: Apply!

Apply drops of your vitamin serum on your face and neck area. Additionally, feel free to apply wherever else you would like its benefits to reach and penetrate. Keep in mind that vitamin c can be used both in the morning, and at night. Follow-up with your favorite non-comedogenic face moisturizer. Lastly, if you are using the serum in the morning, be sure to use a sunscreen in conjunction with the treatment.

Tip: You can choose to use your preferred vitamin C serum as a standalone product or you can put a few drops in your moisturizer and use them as a team. It is also important to note that while you can use vitamin C safely in combination with other types of skincare products, its use with niacinamide may cause the serums to become less effective.
