idea:
this unique icon is actually a mash up between d and s.
the icon is unique and not common on 'dude themed' logo so it will definitely stand out. and as a bonus, you can also see water element, which is essential for skin care... (see the negative space)
also this logo looks good in any color, even just one color (black and white) and it's easy to put this logo in any medium like bottles, t shirts, caps, etc. and it's not too thin so it will look great at the distance, e.g. signage, billboards, etc
