What it is: A silky, pillowy-soft 10% multi acid milk serum that targets dark spots, uneven tone, dullness, and clogged pores to exfoliate and resurface overnight. Contains gluconolactone and glycolic acid that could help reduce blemishes and clogged pores in theory, but there is not enough evidence that they actually work.

What it does: 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.
