TL;DR
Recent skincare developments show that milky acid exfoliants, containing gentle polyhydroxy acids, are a safer and more effective alternative to physical scrubs. They are gaining popularity among brands and users seeking gentler exfoliation.
Recent skincare products featuring milky acid exfoliants are gaining attention for their gentleness and effectiveness, challenging the dominance of traditional physical scrubs.
Multiple brands, including Naturium, Trinny London, and The Ordinary, have introduced milky toners and serums containing polyhydroxy acids such as gluconolactone, lactobionic acid, and azelaic acid. These formulations aim to exfoliate dead skin cells without the irritation often caused by harsher acids or physical scrubs.
For example, Naturium’s Multi Bright Milky Toner (£19) combines gluconolactone, azelaic acid, and moisturizing ingredients like squalane and glycerin, offering a gentle yet effective exfoliation. Similarly, Trinny London’s Tiptoe In (£36) serum uses gluconolactone and lactobionic acid for a mild exfoliation, enhanced with humectants for hydration. The Ordinary’s Saccharomyces Ferment 30% Milky Toner (£12.40) is suitable for a range of skin types, providing gentle removal of dead skin and excess oil.
Experts note that these milky acids are often more tolerable for sensitive skin and can be used more frequently than traditional chemical acids, with some users applying them up to four times weekly.
Why It Matters
This shift towards milky acid exfoliants represents a significant development in skincare, especially for those with sensitive or reactive skin. They offer a safer, less irritating way to achieve smoother, brighter skin and longer-lasting makeup results. As consumers seek gentler options, these products could replace more abrasive physical scrubs, reducing skin damage and irritation.

Background
Physical scrubs have long been a staple in many skincare routines, but concerns about skin damage and irritation have prompted a search for gentler alternatives. In recent years, acids like glycolic and salicylic acid have gained popularity, but they can still cause discomfort for sensitive skin users. The rise of polyhydroxy acids, especially in milky formulations, reflects a broader trend towards skin barrier protection and hydration, influenced by South Korea’s skincare innovations.
