Assuming it’s not illegal money and no coercion was involved, then by definition the customers must have believed that the cosmetic operations were worth it, at least at the point of purchase. Since cosmetic surgery is much less burdened by regulation, externalities, and so on, I would say the prices charged are reasonably close to the market clearing price.
The surgeons in Africa may or may not be subject to greater distortions depending on the local market.
Though I imagine cosmetic surgeons specifically in Africa are paid about the same relative to their skill level, staffing level, and facilities?
