Goop Beauty Sleep Milk Serum | Overnight Glycolic + Hyaluronic Exfoliating Serum | 1 fl oz

Overview: overnight exfoliation that smooths and brightens

Goop Beauty Sleep Milk Serum blends a 10% multi-acid complex with hydrating hyaluronic acid to work while you rest. The silky, milk-like texture glides onto skin, delivering gentle exfoliation that aims to refine texture and promote a luminous, baby-soft feel by morning.

What it targets

• Even skin tone and smoother texture through gentle resurfacing
• Refinement of dullness and the look of pores for a more even surface
• Wrinkle appearance and fine lines with consistent nightly use
• Hydration support to keep skin comfortable and supple

Key ingredients and feel

• 10% glycolic + lactic acids (AHAs) paired with hydrating hyaluronic acid
• Silky, milky texture designed for overnight use without heaviness

How to use

• In the evenings, smooth 1–3 pumps over cleansed face, neck, and chest. Start 4x/week, then work up to nightly use as tolerated.

• Editors’ Tip: it doubles as a five-minute treatment mask or a targeted spot treatment for blemishes.

What customers notice
