Vitamin C Serums: How to Choose

Vitamin C is a holy-grail skincare ingredient, with skin benefits such as antioxidant properties for brightening skin complexion, fading dark spots and improving elasticity; making it an essential skincare ingredient for all.

To ensure you get the most out of your Vitamin C serum, choosing the right one for your skin type and those with the most complimentary ingredients is necessary. 

For those with sensitive skin, it may be difficult to incorporate it into your daily routine as it can be an irritant depending on the concentration used in the product. The higher the percentage of Vitamin C, the more potent the product, leaving a possibility of visible results faster but this may also leave irritation for sensitive skin.

That is why it’s important to know your skin type and how sensitive it may be when choosing a Vitamin C product. Luckily, there are plenty on the market with varying percentages of Vitamin C content to suit even sensitive skin.

Suitable for sensitive skin

Products more suited for sensitive skin, containing a lower percentage of Vitamin C include:

Klairs - Freshly Juiced Vitamin Drop (5% Vitamin C content)

This serum is hypoallergenic with a low concentration of Vitamin C to avoid skin irritation but still provides antioxidant effects to get rid of dull skin and leave skin looking bright and feeling great.

Klairs - Freshly Juiced Vitamin Charging Serum (10% Vitamin C content) 

This NEW serum contains 10% 3-O-Ethyl Ascorbic Acid (Vitamin C derivative) as well as Niacinamide. These two key ingredients work wonders in combination to help improve skin complexion by brightening and also helping with blemishes.

These products contain a lower percentage of Vitamin C and therefore should be more suited to those with sensitive skin, so if you’re just starting out with Vitamin C, these products are a great way to begin incorporating Vitamin C into your daily skincare. Serums such as these can be used in the morning and/or evening but leaving the serums overnight is great for waking up with fresh and radiant skin.
