What's more, vitamin C is a topical ingredient for brightening and diffusing dark spots. “It’s a pigment suppressor which evens out the skin tone,” says Dr Mansouri. As a result, your complexion is left looking clearer and more radiant. Some products, such as retinol and vitamin C in higher concentrations, can cause mild irritation at first and should be used every other day to begin with until your skin builds up tolerance. If your skincare routine includes both vitamin C and retinol, it’s best to use vitamin C products in the morning and retinol products at night – retinol helps cells rebuild overnight but can cause sun sensitivity, whereas vitamin C helps protect from environmental damage so is a good choice for daytime. Salicylic acid can also cause mild irritation so is best used at night; hyaluronic acid can be used at any time of day What should I use after a serum?The real beauty experts among us will also be interested in the different forms of vitamin C that are found in skincare today. Most experts agree that the appearance of 'ascorbic acid' or 'l-ascorbic acid' on an ingredient list is a promising start, but other forms of the vitamin you may come across include sodium ascorbic phosphate and tetrahexyldecyl ascorbate. Who should use vitamin C skincare? An excellent serum for calming irritated or sensitive skin, cult brand Glossier’s Super Bounce serum combines the hydrating power of hyaluronic acid with healing and moisturising vitamin B5. The result is deeply hydrated, plumper and bouncier skin that glows from within. The fragrance- and paraben-free serum is suitable for all skin types, including sensitive and inflamed skin, and the formula is particularly beneficial for acne-prone and scarred skin.

Most commonly, the ingredient is found in serums but you can also slot in a vitamin C moisturiser or cleanser. If you do opt for a serum, Dr Mansouri suggests using it as the first ingredient after you cleanse, before following up with a hydrating moisturiser – and not forgetting that crucial SPF of course. Popular ingredients in facial serums include hydrators such as hyaluronic acid and vitamin E, brightening ingredients such as vitamin C and retinol, and exfoliators such as salicylic acid. These ingredients often pop up in moisturisers, but a serum will deliver them in a much more concentrated form, allowing them to penetrate deep into the skin to produce more noticeable benefits. Serums work hand in hand with the rest of your skincare products, enhancing the effects of your favourite cleanser and moisturiser. Apostolou My freebie! Wow what an amazing product!

As with any change to your skincare routine, it’s best to start slow and work your way up. How should you use vitamin C in your skincare routine? The acidity of vitamin C may cause irritation to people with sensitive skin. If the compatibility between your skin’s pH level, and the pH of the vitamin is off, this may cause a tingling sensation and weaken your barrier function.Eunice24 Good value I had a free sample of this and was so impressed I have bought the full size.
