Vitamin C helps to visibly fade skin discoloration, provide antioxidant support and is suitable for most skin types, making it a multi-tasking must-have for every skincare routine. For more information on the benefits of Vitamin C for skin, read What are the Benefits of Vitamin C Serum for Skin and Face?<\/p>\n

Vitamin C now appears in everything from serums and face moisturizers, to capsules and body lotions at almost every beauty retailer. With so many options and at every price point on the market, how do you know which option is the best for you when shopping for a Vitamin C serum?<\/p>\n

When doing your research to find your ideal Vitamin C serum, you\u2019ll want to consider a few different things: the form (Pure Vitamin C vs. a derivative), the concentration, the added ingredients, the aesthetic, the packaging and of course, the clinical proof.<\/p>\n

Here are a few pointers to get you started and on your way to finding the right Vitamin C serum just for you:<\/p>\n

Form:<\/strong> Vitamin C can appear on the ingredient label as several different names and derivatives such as Tetrahexyldecyl Ascorbate (a stable oil-soluble form of Vitamin C), Ascorbyl Glucoside (a stable water-soluble form of Vitamin C combined with glucose) and many others. But the one you want to look for is L-Ascorbic Acid (Pure Vitamin C) which is the most effective and is the Vitamin C that occurs naturally in your body.<\/p>\n

Concentration:<\/strong> The ideal level of concentration you want of L-Ascorbic Acid is between 10 and 20 percent. The higher the concentration of Vitamin C is, the more potent it is, but also more difficult to stabilize. Going over 20 percent can lead to irritation and won\u2019t increase the benefits for your skin.<\/p>\n

Added ingredients:<\/strong> When shopping for the best Vitamin C serum, you\u2019ll want to checkout what other ingredients have been added to the formula. Look for ingredients that can boost the products efficacy such antioxidants or hydrating, brightening or exfoliating ingredients.<\/p>\n

Aesthetic:<\/strong> The serum\u2019s texture, smell and consistency are something you\u2019ll want to be mindful of when selecting your Vitamin C serum. It should ideally be lightweight, non-greasy and not overly fragrant.<\/p>\n

Packaging:<\/strong> When it comes to your Vitamin C serum, packaging does make it perfect. Its particularly important for your Vitamin C serum to be stored in a dark glass bottle and feature a medicine dropper (rather than a pump) to ensure the freshest delivery of the serum. Exposure to air, light and heat can deteriorate the quality and stability of your Vitamin C serum.<\/p>\n

Proof:<\/strong> Ensure that your Vitamin C serum has been clinically tested. Check the product\u2019s website for clinical studies, before and after photos, as well as reviews from other customers.<\/p>\n
