Can I apply it right after a run or gym session, and do I need to shower first?

The gel is formulated for exactly this scenario: legs that feel hot and heavy after exertion. Its light, fast-absorbing base means you can apply it and get dressed within a minute or two without an oily film transferring to clothes. For best results, apply to clean, dry skin — so showering first is optimal because it removes sweat, salt, and any residue that could interfere with absorption or irritate freshly sensitized skin. If you can't shower immediately, wipe the area with a damp cloth and pat dry before applying. A short upward massage (ankle toward knee) helps the gel spread evenly and the manual movement itself contributes to the lighter sensation. Avoid applying to broken skin, fresh blisters, or areas with chafing.
