if your stars aren’t sticking: plz make sure you’re applying patches to clean, dry skin! in order to stick, hydro-stars need a surface free of moisturizer, makeup, and other skincare products.
if your stars aren’t working: everyone’s skin and spots are different, so finding your perf patch can take time :) all hydro-stars are made with hydrocolloid, which helps absorb fluid, reduce redness, and visibly shrink spots. if you feel like you need something a lil more powerful, try patches with added ingredients like hydro-star + salicylic acid (for deep spots), hydro-star + tea tree (for oily spots), or micro-cloud (for early stage spots).
