The 20 Best Non-Toxic Vitamin C Serums

This post will review the best non-toxic vitamin C serums that not only are made with safe ingredients, but also work well and are effective in improving the appearance of your skin.

Vitamin C serums are great for your skin. They can have many beneficial effects including, but not limited to:

• Vitamin C can help reduce the appearance of dark spots and hyperpigmentation and help protect against the development of new dark spots or hyper-pigmented areas (reference).
• They have powerful anti-aging effects (reference).
• They can help decrease acne and acne scarring.
• Can help defend skin from the damaging effects of environmental stressors such as pollution and smoke (reference).
• Help decrease melasma (reference).
• Supports the skin’s natural collagen production to help make skin appear more youthful (reference).
• Help decrease sun damage from both UVA and UVB rays (reference).
• Prevent sun damage by neutralizing free radicals, an effect which is not seen with sunscreens - under laboratory conditions, the application of a 10% topical vitamin C shows a reduction of UVB-induced redness by 52% and sunburn cell formation by 40-60% (reference).
• They act as a potent anti-oxidant which helps protect the skin from oxidative stress and environmental damage (reference).
• They have anti-inflammatory effects which is helpful for treating many different skin conditions and can promote wound healing and help prevent scarring (reference).
• Vitamin C can help replenish the skin's vitamin E levels, which has anti-oxidant effects and helps prevent against oxidative stress and maintains the collagen network in the skin (reference).
• They can help brighten the skin, even skin tone, and improve skin radiance.

Almost everyone could benefit from adding a vitamin C serum to their skincare routine. However, when considering which vitamin C serum to buy, you want to be sure to choose one that is not only effective, but is also safe and non-toxic.

Unfortunately, the personal care industries in many countries, including the USA and Canada are currently under-regulated, so that harmful ingredients including carcinogens, endocrine disruptors, skin irritants, allergens, respiratory irritants, neurotoxins and other potentially toxic ingredients can be used in skincare products (please refer to the reference section at the end of this post for further reading on this issue). And knowing that our skin is the largest organ in our body and that many of these ingredients can be absorbed directly into the blood stream, it is very important that you avoid products with any potentially harmful ingredients in them.

Luckily, in recent years there have been more and more brands that are focused on producing safe, non-toxic skincare products, including vitamin C serums, so there are many non-toxic vitamin C serums on the market to choose from.

In this post I have included a list of the 20 best non toxic vitamin C serums including organic, natural and vegan options and options at varying price points, so there should be something here for everyone. Here you will find vitamin C serums that are great for all ages including beginners and those over 50 who are more experienced and may require more concentrated and even more effective ingredients.

The 20 best non-toxic vitamin C serums:

Beautycounter All Bright Vitamin C Serum

The Beautycounter All Bright Vitamin C serum is my personal favourite vitamin C serum. I have seen such dramatic improvements in my skin since I started using it (see my before and after photos below). Compared with most vitamin C serums on the market that are made with L-ascorbic acid which is an unstable form of vitamin C that starts to oxidize and lose effectiveness quickly when exposed to light, the Beautycounter All Bright C Serum is instead formulated with two ultra stable forms of vitamin C - 5% bis-glyceryl ascorbate and 5% tetrahexyldecyl ascorbate.

This vitamin C serum is also made with Curcuma Longa (turmeric) root extract and Myrciaria Dubia (camu camu) fruit extract. These extracts are powerful antioxidants that help decrease the appearance of fine lines and wrinkles, reduce dark spots and improve signs of skin fatigue. It is also EWG verified, cruelty free and vegan.

In addition to formulating their products with safe ingredients, Beautycounter also tests their products for contaminants to ensure that no unwanted harmful ingredients end up in their products by mistake somewhere during the manufacturing process.
