TL;DR
Recent launches of milky acid exfoliants demonstrate they can be a gentler, more effective alternative to physical scrubs. These products combine soothing ingredients with mild acids, making exfoliation accessible for sensitive skin types.
Recent skincare product launches highlight that acid exfoliants, especially milky formulations, are safer and gentler than many believe, offering effective exfoliation without irritation.
Multiple brands, including Naturium, Trinny London, and The Ordinary, have introduced milky acid exfoliants containing polyhydroxy acids (PHAs) and other gentle acids. These products are designed to exfoliate dead skin cells effectively while minimizing redness and irritation, making them suitable for sensitive skin. For instance, Naturium’s Multi Bright Milky Toner combines gluconolactone, azelaic acid, and moisturizing ingredients like squalane and glycerin, providing a soothing, brightening effect. Similarly, Trinny London’s Tiptoe In uses gluconolactone and lactobionic acid for gentle exfoliation, with added humectants for comfort. The Ordinary’s Milky Toner offers a cost-effective option that suits all skin types, including oily and dry skin, with a gentle, non-drying formula.
Why It Matters
This shift towards milky, gentle acids in skincare is significant because it challenges the misconception that acids are harsh and unsuitable for sensitive skin. It broadens the range of effective exfoliation options, potentially reducing reliance on abrasive physical scrubs, which can cause microtears and irritation. For consumers, this means safer, more comfortable skincare routines that still deliver visible improvements in skin texture, tone, and makeup application.

Background
Acid exfoliation has traditionally been associated with harsh formulas like glycolic acid toners, which can cause redness and irritation, especially for sensitive skin. The popularity of milky toners in South Korea, emphasizing hydration and skin barrier protection, has influenced Western brands to develop milder, more soothing formulations. Recent product launches in 2026 reflect this trend, with a focus on polyhydroxy acids (PHAs) which are known for their gentler action compared to alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs). Experts and brands are now promoting these milky acids as safer alternatives for regular exfoliation, even for those with sensitive or reactive skin types.
