'Duschgel' (shower gel) is a compound word made up of 'die Dusche' (the shower) and 'das Gel' (the gel). So it literally describes a gel that you use while showering.
Das neue Duschgel riecht sehr gut nach Zitrone.

Common combinations are 'eine Flasche Duschgel' (a bottle of shower gel) or 'eine Tube Duschgel' (a tube of shower gel). People also often say 'Duschgel für…' (shower gel for…) followed by a skin type, e.g. 'für empfindliche Haut' (for sensitive skin).

'Seife' and 'Duschgel' are both products you can use to clean the body. 'Seife' is often a solid bar, but it can also be liquid. 'Duschgel' is liquid or gel-like and is used especially when showering. That is why the words are easy to confuse: both are found in the bathroom and are meant for the body. When talking generally about washing your hands or about a bar of soap, 'Seife' fits better. When showering, 'Duschgel' sounds more natural.
