When it comes to skincare, vitamin C and niacinamide have rapidly risen in popularity, becoming favourites for their powerful and transformative effects. Individually, each ingredient offers significant benefits, from brightening dull skin to regulating oil production.
But can combining vitamin C and niacinamide deliver even greater skincare benefits, or could mixing these ingredients potentially do more harm than good? In this blog, we’ll explore the truth about combining vitamin C and niacinamide, dispel common myths and help you confidently integrate these powerhouse ingredients into your daily routine.
Understanding Vitamin C and Niacinamide
What is Vitamin C?
Vitamin C, also known as ascorbic acid, is a potent antioxidant revered in skincare circles for its remarkable ability to protect skin cells from environmental damage. Regular use of vitamin C can brighten uneven skin tone, stimulate collagen production and reduce visible signs of ageing, leaving your complexion looking radiant and revitalised.
What is Niacinamide?
Niacinamide, a form of vitamin B3, is equally celebrated. It helps regulate sebum production, minimises enlarged pores and reduces inflammation and redness. It’s also effective at strengthening the skin’s natural barrier, resulting in improved hydration and a smoother skin texture.
The Myth of Vitamin C and Niacinamide Incompatibility
Despite their numerous individual benefits, mixing vitamin C and niacinamide has long been a controversial topic within skincare discussions. The idea that these two ingredients should never be combined originated from outdated research suggesting potential incompatibility due to differing pH levels.
Early studies indicated that mixing them could cause skin irritation or diminish effectiveness. However, modern formulations and advanced research have proven this to be nothing more than a skincare myth.
The Truth: Can You Safely Mix Vitamin C and Niacinamide?
Recent studies and dermatological consensus confirm that it is indeed safe and beneficial to use vitamin C and niacinamide together. Thanks to advancements in skincare technology, today’s formulations are carefully stabilised, ensuring compatibility and efficacy. Moreover, combining these ingredients doesn't just maintain their individual effectiveness - it actually enhances their overall impact on skin health.
