Corundum crystals are considered safe because they are non-toxic to skin and eco-friendly. Corundum is almost identical to sapphire, one of the hardest known mineral materials (second only to diamond). Sapphires are a form of aluminium oxide. This hardness makes corundum ideal for exfoliating the top layer of facial skin to remove dead cells and unblock pores.

Niacinamide boosts skin immunity and increases the production of the skin’s natural ceramides in the stratum corneum. This results in a more hydrated, dewy complexion and a reduction in the appearance of fine lines. Niacinamide assists in regulating oil glands and minimising inflammation. Topical Vitamin B3 also reduces the appearance of hyperpigmentation by preventing melanin transfer from the melanocyte to the keratinocyte.
