Refill packs commonly come in 16-count and 32-count options. Some clear refill packs include two sizes: 16 classic stars (14 mm) and 16 big stars (18 mm).
Apply to clean, dry skin and press firmly. Leave on overnight or for at least 6 hours; remove in the morning and replace with a fresh patch if needed.
Instructions advise leaving salicylic-acid patches on overnight or for at least 6+ hours and limiting use to about 1–3 times per week.
Product notes and reviewers report improved stickiness and long-lasting wear; many users say the patches stay on through sleep and normal morning routines.
Most patches are made from hydrocolloid (often described as 100% hydrocolloid). Some versions also include salicylic acid as an active ingredient to help unclog pores.
Some refill packs come inside a refillable mirrored compact that holds about 32 patches. A reusable mirrored compact is also noted as available separately for travel and storage.
A clinical study reported a noticeable difference in about six hours. Reviewers commonly report rapid improvement—often overnight—with some noting clearer results within roughly 48 hours.
Product details label them for acne-prone skin, and several descriptions also note they are suitable for sensitive skin.
