FAQs

What are the benefits of using vitamin C in skincare?

Antioxidant protection — Vitamin C neutralises free radicals and oxidising molecules contributing to skin damage.

Reduced fine lines and wrinkles — Vitamin C skin products can help improve the appearance of fine lines and wrinkles.

Fade dark spots and pigmentation — Vitamin C can help improve the appearance of dark spots and pigmentation.

Hydration — Vitamin C supports the skin's natural moisture barrier, helping to retain hydration and prevent moisture loss. This can result in a more hydrated, plump and supple complexion.

Is vitamin C suitable for all skin types?

Yes, its moisture retention properties can help dry skin maintain hydration, while its antioxidants can help oily skin by soothing skin that can contribute to excess sebum production. Depending on the concentration, vitamin C and, more specifically, L-ascorbic acid can be too intense for people with sensitive skin — instead, try a stabilised vitamin C derivative such as tetrahexyldecyl ascorbate.

Who should use vitamin C skincare products?

Vitamin C skincare products can work well for anyone who wants to brighten their complexion, reduce signs of ageing and enhance their skin’s natural defence against environmental damage. If you have dull skin, hyperpigmentation or uneven skin tone, you can benefit from adding vitamin C to your skincare routine.

When should I introduce vitamin C into my skincare routine?

You can start incorporating vitamin C into your skincare routine as early as your late teens or early 20s to help prevent the onset of visible skin ageing. If you’re new to vitamin C skincare products, test a product with a lower concentration of vitamin C, such as our C-Tetra vitamin C serum with tetrahexyldecyl ascorbate, and see how your skin responds to it.

How often should I use vitamin C skin products in my routine?

Vitamin C for skincare requires cumulative use to brighten and clear your complexion. We suggest using it each morning for all-day support.

Can I use vitamin C skin products alongside other skincare ingredients?

With its skin conditioning properties, vitamin C skincare products pair well with ferulic acid and niacinamide and help combat oxidative stress when layered under your sunscreen. We always suggest our CSA philosophy, vitamin C and sunscreen in the morning, followed by vitamin A in the evening.

What concentration of vitamin C do your products contain?

Our products feature a range of proven forms of vitamin C at various concentrations. We offer L-ascorbic acid serums between 15% and 30%, along with serums that use tetrahexyldecyl ascorbate, which has a higher pH range perfect for those new to vitamin C or with sensitive skin.

This variety gives everyone, from beginners to those with more resilient skin, a product that suits their needs and maximises the effectiveness of vitamin C without causing irritation.

How should I layer my skincare products with vitamin C?

For best results, apply vitamin C after cleansing and toning but before applying moisturisers and sunscreens. This allows your skin to fully absorb the vitamin C serum.

What precautions should I keep in mind while using vitamin C skincare products?

When using vitamin C products, store them properly — away from light and air — to maintain their stability and efficacy. Additionally, because vitamin C can increase sun sensitivity, apply a broad-spectrum sunscreen during the day to protect your skin from UV rays. Start with a lower concentration of vitamin C if you have sensitive skin and consider patch-testing a new product to check for adverse reactions before applying it to your entire face.

How long will it take to see results from vitamin C?

While individual results can vary, typically, you can expect to see noticeable improvements in your skin's brightness and tone within 3 to 4 weeks of consistent daily use. For more significant changes, such as reduced appearance of dark spots and fine lines, longer use is generally necessary. Be consistent in applying vitamin C so your skin can achieve and maintain lasting results.

Is sunscreen a must when using vitamin C?

Absolutely, sunscreen is a crucial part of your skincare routine when using vitamin C. While vitamin C is an antioxidant that can help mitigate some effects of sun exposure, it does not provide sun protection. Additionally, it may cause photosensitivity and increase the likelihood of sunburn. Therefore, applying a high-SPF sunscreen every morning is essential to protect your skin from potential damage.

Is vitamin C safe for pregnant or breastfeeding women?

Unfortunately, as a cosmetic brand we are unable to provide specific medical advice relating to our products. We would strongly advise speaking with your GP or Midwife so that they can give you an accurate recommendation. The full ingredients list for each of our products can be found on the product pages of the Medik8 website.

How should I store vitamin C-based products?

Store vitamin C skincare products in a cool and dark place to prevent them from oxidising and degrading prematurely. Exposure to high temperatures, light or air can break down the vitamin C and reduce the ingredient’s effectiveness. Many products are packaged in opaque, air-restrictive containers to help maintain their stability, so keep them tightly closed and away from direct sunlight.

What other products can I find at Medik8?

Alongside vitamin C, Medik8 offers a comprehensive range of skincare products including direct acids, peptides, sun protection and more, all designed to target specific skin concerns and promote overall skin health.
