Use at night

This silky, stealthily effective 10% multi-acid AHA 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 uneven skin tone, dull texture, fine lines, 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.

  •  30 mL / 1 fl oz 


Editors’ tip: The serum also works brilliantly as a five-minute treatment mask and as a spot treatment for blemishes.

Beauty as wellness.

For us, beauty comes from the inside out. We use clinically proven and best-in-class ingredients at active levels to create luxurious skin, hair, and body essentials that deliver high-performance results and enliven the senses with exquisite textures and beautiful scents.

Clean, to us, means that we vet our ingredients with strict attention to quality, while prioritizing ingredients that are ethically sourced and cruelty-free wherever possible. We also strive to use sustainable biobased sources that are nonpersistent in the environment. In addition, all our beauty products are formulated without silicones, formaldehyde donors, parabens, SLS, SLES, PEGs, polyacrylamides, TEA, DEA, phthalates, or synthetic fragrance, among many others that we proactively screen for based on published and ongoing scientific studies. Our approach to formulation is a future-forward consciousness about our health.   


The clean beauty movement isn’t perfect, though; it’s evolving—and our goal is to evolve with the science in the most transparent way we can. We source all the ingredients for our goop Beauty products with a high standard of safety and quality, while recognizing that despite our best efforts, trace levels of incidental chemicals may occur as a result of manufacturing and supply chain complexities. We are committed to making careful choices in our sourcing and formulation to minimize the potential presence of any trace amounts of incidental ingredients. 


We hope you love the goop Beauty collection as much as we do.
