What beauty procedure makes the most money?

Offering semi-permanent eyebrows would earn you more money on average. Dermabrasion is also intended to remove dead skin cells, but relies more on physical exfoliation techniques. Dermabrasion is a skin rejuvenation procedure in which a rotating dermabrasion device removes the first layer of skin. The difference between dermabrasion and microdermabrasion is that microdermabrasion is usually a lighter version of the exfoliating procedure, while dermabrasion is more suitable for deep scars or advanced hyperpigmentation.

Dermabrasion requires more downtime for the skin and has the potential to cause more side effects.
