Florence by Mills combines hydrocolloid with salicylic acid, peppermint oil and tea tree oil in one patch, while Starface separates plain hydrocolloid stars from medicated versions. That difference decides whether you get botanicals and acid together or choose plain coverage versus stronger action. Acne patches are small stickers placed over a pimple to cover it and absorb fluid. Hydrocolloid is the wound-dressing gel base that seals the spot and soaks up oil and pus.

What is inside each patch?
Florence by Mills Spot a Spot Patches list four key ingredients — hydrocolloid, salicylic acid, peppermint oil and tea tree oil — in a 36-sticker pack, according to the Florence by Mills product page. Ulta Beauty states the salicylic acid is a BHA that exfoliates and keeps pores clear. Ulta Beauty also states tea tree oil calms inflamed skin while hydrocolloid seals spots and absorbs oil and impurities. Starface takes a split approach.
Its classic Hydro-Stars are made from 100% hydrocolloid with no added drug actives, according to the Starface World product listing. Starface describes that version as vegan, cruelty-free and dermatologist-tested. Starface sells a separate Hydro-Star + Salicylic Acid version with 1% salicylic acid, according to the Starface World salicylic-acid listing. Starface lists the salicylic-star base as cellulose gum, polyisobutene, petroleum resins, styrene/butadiene copolymer, paraffinum liquidum, polyurethane and salicylic acid, according to the Starface World BFF Bundle page.
How does hydrocolloid work?
Hydrocolloid absorbs surface fluid such as oil and pus while covering the lesion to discourage picking, according to Cleveland Clinic dermatologist guidance. That covering action helps surface whiteheads and pustules. It works best after a spot has opened or come to a head.
Plain hydrocolloid has little to draw out from deep, unopened or cystic lesions, according to Cleveland Clinic guidance reported in a pimple-patch explainer. That limit explains why plain stars suit visible surface fluid. Deep, painful bumps under intact skin need a different approach.
When does salicylic acid add value?
Salicylic acid is a beta hydroxy acid that unclogs pores, according to Starface World and Target listings. With hydrocolloid, it is positioned to visibly shrink spots that need stronger action. That combination targets plugs and oil inside the pore, not just surface fluid.
Florence builds salicylic acid into its standard patch alongside botanical oils. Starface reserves 1% salicylic acid for its separate medicated star. Choose the medicated option when surface coverage alone leaves clogged or recurring spots unchanged.
Which choice fits oil-sensitive skin?
Florence bundles peppermint oil and tea tree oil into every standard patch. Tea tree oil calms inflamed skin, according to Ulta Beauty.
Peppermint oil adds fragrance and cooling that some sensitive users may want to avoid. Starface splits plain hydrocolloid from salicylic-acid and tea-tree variants, according to Target and Starface World listings. That separation affects choice for oil-sensitive or acne-prone users who react to botanicals.
- Pick Florence standard if you want acid plus botanicals in one step for surface spots.
- Pick Starface Hydro-Stars if you want plain hydrocolloid with no added drug actives.
- Pick Starface salicylic-acid stars if you want 1% salicylic acid without bundled oils, and limit use to 1-3 times per week as Starface advises.
