I bought an SBC TSV a while ago that included the Collagen Gel and Serum. I think the Serum is mainly for the face, but the gel can be applied to the face and body. I believe you are supposed to apply the serum to the face first, followed by the gel, but you can use either independently.
As a fairly hairy man, I find the gel absorbs easily into my skin, even if I apply it over my trimmed beard. I have used a few different SBC gels and find they all absorb easily with no greasy feeling and are especially nice to apply after a shower or bath when your skin is damp.
If you can afford it, get the gel and serum and use both together. The collagen shower cream is nice too and doesn't smell too feminine so can be used by both sexes. You can get a lot of foam if you use a shower puff and turn the shower to a dribble while applying it. I only use two or three pumps and find it's enough for a full body wash.
Hope this helps, but I'm sure there are many SBC users out there that can offer more advice.
