Salaries will vary depending on the specific position and the set up at the individual salon or spa. Salaried aestheticians can expect to earn from $20,000 to $60,000 depending on the location of the salon and personal experience. An experienced aesthetician working at a high-end salon in a major city would expect to earn a salary at the higher end of the scale. Once established with a customer base, it may be possible to earn more if a commission-based system is used. In this case, commission would start at about 40% of the service costs and increase with experience. In addition, selling recommended skin care products may create further earnings through sales commission.
