This silky, stealthily effective 10% multi-acid milk serum works overnight and over time to exfoliate, resurface, and moisturize, leaving your skin glowy, smooth, practically poreless, and baby-soft. While the serum is high-strength to deliver intense resurfacing—targeting skin tone, uneven texture, wrinkles, dullness, spots, and clogged pores—it’s also remarkably gentle on skin. The lush, velvety formula comforts skin with a restoring “desert milk” made of soothing, moisturizing extracts of Kalahari melon, jojoba, and aloe, as well as oat beta-glucan, hyaluronic acid, and squalane. Bonus: Sleep Milk has none of the stickiness or powerful irritation of typical AHA serums, even as it sweeps away dead skin cells and debris for a dewy-fresh glow.
