That's just the shaving gel (to shave with/on).
You squeze out a tiny amount and turn it into lather between your palms, then apply it to your face. I feel like it has the best uh, "gliding properties" and doesn't really dry out my skin.
However a rich lather from a good soap & good brush (+ a drop of olive oil for hard bearded ppl.) was still the best in terms of gliding and caused the least irritations. But I can't use the brush anymore :/
Some cheap gels (or shaving creams) can be fine too, just don't buy "out of the can lather" with aerosol. It's bad for your skin.
Since I get acne (whiteheads) sometimes, I never resuse a blade and always aplly acidic treatment after shaving (to even out the skin's ph level).
In case my skin is clear and has been clear before the shave: "DERMASENCE AHA Effects plus C" (probably no avail. outside Germany. The main ingredient is "Glycolic Acid" though.)
Otherwise I mix lemon juice (either concentrate or I squeeze out a lemon) into a cup of water and rinse my skin with that after the post-shave cold water treatment.
The 34c is fine btw. - I'm not quite sure if it's the best choice for noobs, but it was my first (and to this day only) safety razor and I like it a lot.
