Designed for evening use, it resurfaces flaky or rough patches, targets dark spots and dullness, and leaves skin feeling softer and looking more luminous with repeated use. It can be used across the face, neck, and chest and also doubles as a quick mask or a targeted spot treatment.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly will I see smoother, more radiant skin?\u003c\/h3\u003e\n\u003cp\u003eSome users notice immediate softening after the first application because the formula combines acids with moisturizing ingredients to avoid over‑drying.

Those with acne‑prone skin often find chemical exfoliation helpful for unclogging pores, but start slowly and combine with gentle, non‑irritating cleansers and moisturizers. Always use sunscreen daily while using acid exfoliants to protect renewed skin.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePatch test first on inner forearm or behind ear\u003c\/li\u003e\n  \u003cli\u003eIntroduce gradually to avoid irritation\u003c\/li\u003e\n  \u003cli\u003ePair with daily SPF to protect fresh skin cells\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: goop Beauty Sleep Milk Serum suits anyone looking to refine skin texture, smooth fine lines, reduce the appearance of dark spots, or minimize clogged pores without a heavy, oily feel.
