ESK – 8-hour BHA exfoliating mask

Hydroxy Overnight Mask is formulated with Salicylic Acid (5%), a Beta Hydroxy Acid (BHA), and Urea (10%), this versatile treatment actively assists in the management and treatment of acne, premature ageing and transepidermal water loss.

Penetrating the top epidermal layers and dissolving the intercellular junction (desmosomes) between healthy and dead skin cells, the mask gently exfoliates the face by breaking down structural keratin proteins and softening cornified skin cells. Offering a sebo-supressive effect, this gentle formulation inhibits excess sebum production and purges the skin of bacterial debris and acne-causing microbes.

Considered a gentler alternative to water-soluble Alpha Hydroxy Acids (AHAs), Salicylic Acid, a fat-soluble antibacterial and anti-inflammatory aspirin derivative, is shown to effectively treat and manage acne lesions, including post-inflammatory hyperpigmentation, redness and enlarged pores.

As Urea is proven to serve as both a moisturising agent and penetrative enhancer when used in conjunction with a key active, the mask’s exfoliating benefits also address the physical signs of photodamage, including pigmentation, discolouration, texture, fines lines and wrinkles.

“Premature ageing is often packaged up with impaired skin barrier function,” said Dr. Ginni Mansberg, co-founder of Evidence Skincare (ESK). “Our skin is susceptible to both biological and environmental stressors, sometimes simultaneously, so it was important for us to create an affordable product that scientifically tackles multiple skin concerns at once.”

Designed to be used on freshly cleansed skin 1-2 times a week as a night mask, or as a spot treatment when needed, the Hydroxy Overnight Mask retails for $50 RRP and is available globally at As a local, ethical, and cruelty-free business, Evidence Skincare (ESK) offers free shipping Australia-wide and provides customers with a money-back guarantee on all purchases.
