This is slightly stronger than the All Day Brightening and Balancing serum, comprising of 5% pure vitamin C. However, it still makes a suitable beginner product. The texture is water-like, absorbing quickly. Thus, it feels less moisturising, replaced by better brightening properties ✨ It comes in a black bottle, which helps prevent oxidation from light yet more prone to absorb heat. I’ve also been storing this in the fridge and have found very slight oxidation so I would recommend storing it in a cool, dark place.
