The Ordinary Alpha Arbutin: a skin treatment serum for excess melanin.  Alpha Arbutin 2% + HA is a concentrated serum with purified Alpha Arbutin and Hyaluronic Acid for hyperpigmented skin by Deciem. It visibly improves skin prone to spots and hyper-pigmentation. It is used at a high 2% concentration versus a standard concentration of 1% and supported with a next-generation form of Hyaluronic Acid for enhanced delivery. It is much stronger in effect than Arbutin or Beta Arbutin. It is extremely sensitive to degradation in the presence of water if the pH of the formulation is not ideal. The pH of this formula is 4.9 which is shown to be the most suitable pH to minimize degradation of Alpha Arbutin. Made in Canada. How To Use: Apply a few drops to your face in the morning and at night before oils, moisturizers, and creams. Recommend wearing sun protection during the day when using this product.

Key Ingredients: Alpha arbutin: an ingredient with visible brightening effects. Hyaluronic acid: supports the delivery of alpha arbutin and provides a hydrating, plumping effect.
