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.

So we use clinically proven and best-in-class ingredients at active levels to create skin care, skin-boosting ingestibles, and body essentials that are luxurious, deliver high-performance results, and enliven the senses with exquisite textures and beautiful scents. We don’t rest until we think our products are perfect—safe enough and powerful enough for noticeable results. (All our products are formulated without parabens, petroleum, phthalates, SLS, SLES, PEGs, TEA, DEA, silicones, or artificial dyes or fragrances. And our formulas are not tested on animals.)
