How will it feel on my Skin?:. Sleep Glycolic™ features a lightweight, silky texture that absorbs effortlessly into the skin. Upon application, you may experience slight tingling—this is completely normal and indicates the active glycolic acid is working.

Skin remains comfortable throughout the night, and by morning, you'll notice a smoother, softer surface with a healthy, illuminated glow.. Who is it Suitable For?. Those with dull, lacklustre complexions seeking visible radiance and luminosity. Individuals concerned with uneven skin texture, rough patches, or surface irregularities. Anyone experiencing early signs of ageing, including fine lines and loss of firmness. Those with hyperpigmentation, dark spots, or uneven skin tone. Individuals with mild to moderate congestion and enlarged pores. Normal, combination, and oily skin types. Those seeking to enhance in-clinic peel results or preparing for their first professional peel. Clients already using vitamin A products and wanting additional exfoliation support. Not recommended for sensitive or reactive skin types.. Why choose Medik8 Sleep Glycolic™?.
