Not totally sure about blackheads, but either one of the two will likely work. Sowilo is always the way to go for anything health related. As for smooth skin, this is a matter of yin and where Laguz works well. Gebo could probably work as well, given its relation to Venus, but Laguz seemed to have more health connotations, and should work well enough anyway.
Either Friday or Monday would be fine, but Friday and Venus is more related to reducing inflammation. Monday is more related to fluids and the moon. Both health problems aggravate the other: Too much heat dries up liquid. Too little liquid creates heat and friction.
In regards to solar energies, you should do a full working, like the Sun Square.
The runes represent the energies of the universe, which can be applied to the body, just as they can the soul. Some of them are less directly obvious and not as related to health itself, but all can have some relationship with the body. First you correlate the rune to a planet, then you check that planet's correlation to the body part or other diseases.

Are there any runes for acne spots? Can I vibrate the runes on my skin without a specific moon?
Spots as in scars? The same runes would most likely work, as they improve the body's ability to heal and repair.
I don't vibrate them directly on my skin, but rather just my aura, because the energy should work broadly across the body. For example, it might stimulate a specific organ to create more tissue that you may need.
When you are doing short term workings, you can get away with a poor moon sign, but if you want to create large or permanent changes, then you should choose the best astrological conditions. Even beyond moon signs, I would hold off on a permanent working, unless you have an emergency, because Venus will soon be retrograde.
Instead, use the Sun in Leo opportunity to improve your vitality, as the Sun's energies fuel all parts of the body, including our yin side (skin, hydration, luster, etc).
