How Should I Use Vitamin C?

As a general rule of thumb, serums are the best skincare delivery vehicle for Vitamin C. In terms of your skincare routine, serums come before moisturisers. Although Vitamin C can be used both morning and night, there are a few things to keep in mind to help get the most out of using your Vitamin C serum.

1. When starting out, introduce it to your routine slowly. Start off with twice a week maximum and build up to more regular use.

2. If you use retinols at night, use your serum in the morning to avoid interaction.

3. When using skincare acids (eg. AHAs, BHAs) or if have dry or sensitive skin, consider using Vitamin C at a different time of the day.

4. For optimal use, store your serums in the fridge to delay oxidisation. After opening, serums containing pure Vitamin C (L-Ascorbic Acid) begin oxidising after 3 months, reducing their effectiveness.

5. The effectiveness of pure Vitamin C is pH dependent. If your skin’s pH is too high or low, this will make Vitamin C less effective. To avoid this, use it directly after cleansing and wait 20-30 minutes before the next step in your skincare routine. If you’re looking to save time, use a pH adjusting toner right after cleansing.

Our favourite Vitamin C Serums

For a serum suitable for all skin types and ages, Tosowoong’s Spot Whitening Vita Clinic Ampoule Serumis a great way to introduce Vitamin C into your routine. This serum combines Vit C from multiple sources, with anti-aging peptides, antioxidants and more, making it ideal for minimising the effects of damage on the skin.

APLB’s Vitamin C Ampoule Serum is also perfect for more sensitive skin. It is made with pure L-Ascorbic Acid and brightening niacinamide and sea buckthorn to help to create a more vibrant complexion free from unevenness.

If you’ve got stubborn pigmentation and dark spots, COSRX Vitamin C Serum is a game changer! It helps improve skin's brightness. COSRX's potent serum is formulated with a stabilized form of Vitamin C at a pH of 3.36. This assists to minimise reactions when the product comes into contact with air. 

For a fragrance-free option, SOME BY MI’s Galactomyces Pure Vitamin C Glow Serum is one to consider. It helps exfoliate dull and even skin tone and firm up skin for long-lasting lustre. Not only does this product improve skin texture, it can reduce dryness and flaking by up to 85.94% after use.

However, thanks to its unstable profile, pure L-Ascorbic Acid is not for everyone. If you’re looking to avoid the issues with oxidisation with pure Vitamin C, then try Neogen Real Vita C Serum. This serum is made with Sodium Ascorbyl Phosphate (SAP), a stable form of Vit C that produces collagen synthesis and protects skin from oxidative damage. Unlike L-Ascorbic Acid, it is more stable when exposed to light and air, meaning your serum will last for longer.

For an option featuring Vitamin C from fruit, try SOME BY MI’s Yuja Serum. Formulated with Korean Yuja extract and niacinamide for brightening, glutathione to lighten dark spots and prevent melanin pigment production, it restores dull and stressed skin.
