ReVeal (dull, sun-damaged skin)
EnLighten (pigmentation concerns)
Do not combine with retinol or niacinamide serums. If you have a known sensitivity to acidic products, introduce Pure-C Crystals slowly over 3 weeks to allow the skin to acclimatise.

L-ascorbic acid (vitamin C)
Pure L-ascorbic acid is the ultimate strength and most widely studied form vitamin C. Vitamin C is a powerful antioxidant that fortifies the cells to protect them from UV and environmental damage. It promotes the formation of collagen to reduce the appearance of fine lines and wrinkles while promoting skin lightening by suppressing melanin production providing a more even skin tone. L-ascorbic acid is also a potent anti-inflammatory, and it reduces skin redness while accelerating skin healing.

Alpha lipoic acid (ALA)
A powerful antioxidant that works synergistically with L-ascorbic acid for amplified free radical protection. ALA also reduces ageing glycation in the skin, the process by which sugars attack collagen fibres leading to wrinkle formation. It is also able to reduce the appearance of enlarged pores, reduce inflammation and improve vital blood flow and nutrient delivery to the skin.
