Some listings use aluminum-based actives (for example, Aluminum Zirconium 20% and Aluminum Sesquichlorohydrate 20%), while other products are labeled explicitly aluminum-free.
Many products list 'Normal' skin as suitable; several also indicate compatibility with Sensitive, Dry, and Mature skin types.
Options include scented formulas (e.g., Fresh, Cucumber & Mint, Rose, Lime & Coconut, Sandalwood, Coconut, Peach/Vanilla/Orange) as well as unscented/ fragrance-free versions.
Several items advertise no white residue or no visible residue; some describe quick-drying, clear-going formats (for example, lotions or formulas that go on clear).
Descriptions generally instruct applying to clean, dry underarms or skin (swipe or glide on). One listing specifically notes applying a thin layer at night and again in the morning.
