Niacinamide Mandelate

Niacinamide mandelate is a compound combining niacinamide (also known as vitamin B3) with mandelic acid, an alpha-hydroxy acid derived from bitter almonds. This pairing creates an ingredient designed to deliver the skin-conditioning benefits of niacinamide whilst potentially offering mild exfoliating properties from the mandelic acid component.In formulations, niacinamide mandelate functions as a skin conditioning agent, working to maintain skin hydration and support the skin's natural barrier function. The ingredient is found across a range of skincare products, though specific prevalence …

Niacinamide works primarily by supporting the skin's natural moisturising factor and helping to regulate sebum production, which may be particularly relevant in acne-prone skin. The mandelic acid component offers gentle exfoliation by loosening the bonds between dead skin cells on the surface.As a hybrid molecule, niacinamide mandelate delivers both conditioning and mild chemical exfoliation in a single ingredient. The specific transdermal behaviour and penetration depth of this particular compound require further research to fully understand its performance in formulation.

Niacinamide mandelate can typically be used daily or as tolerated. If you are new to products containing mandelic acid or niacinamide, introduce the product gradually to allow your skin to adjust. If using multiple actives, consider spacing them out to minimise potential irritation. A small amount is usually sufficient — follow product instructions for guidance on application.

Niacinamide is generally well-tolerated across most skin types. The mandelic acid component may cause mild irritation or sensitivity in some individuals, particularly on first use or at higher concentrations. If you have very sensitive skin or are pregnant, consult a healthcare professional before use.
