For decades, sunscreen occupied an awkward place in the daily routine—something you wore because you had to, not something you looked forward to applying. Then serums got lighter, moisturizers got smarter and the skin-care-sunscreen barrier began to blur. Now, the category’s latest evolution is taking shape in a new texture: milk.
Milky products have taken over everything from toners to fragrance, so it only makes sense that milky sunscreens are having their moment as summer approaches. Milk sunscreens, which data from Spate shows are spiking in interest, hit the sweet spot between a lotion and a liquid, making them a dream to apply—thin enough to sink in in seconds, rich enough to deliver a serious surge of hydration
Part of what makes the milk format so compelling is its versatility. Whether powered by mineral zinc oxide or elegant chemical filters, a fluid, milk-like base allows actives to disperse more evenly, dry down more cleanly and play nicely with serums, tints and foundations layered on top.
Ahead, we’ve rounded up eight formulas to consider as you start putting together your summer SPF lineup.
