Pink vs Clear. This (the original) has a pink guide colour built in — you see exactly where you've applied, which is why first-time tanners love it. The Clear version skips the guide colour entirely — built for repeat tanners who already know their pattern and don't want the visual cue. Same hourly develop time, same depth options. Pick by experience level.

Yes — wear the sock during develop and you get a clean tan line at the cuff for the Sock Test reveal. Heads up: because this is the pink (guide-colour) version, a little colour will tint the sock cuff while it develops. It washes out in one cold cycle. If you want pristine cream cuffs, use the Clear Mousse instead.

Yes — Medium develops in 60 minutes. Two hours = Dark, four hours = Ultra Dark. The longer it sits, the deeper it goes. Pick the depth by the clock, not the bottle. Colour keeps developing after rinsing, so don't judge it the second you step out of the shower.

Wash them thoroughly with soap straight after applying — especially between the fingers and around the nail beds. Use the mitt on the backs of your hands at the very end with whatever product is left on it, blending out from the wrist. Same rule for knees, elbows and feet: go sparingly, blend it out.
