Hyperpigmentation is arguably the biggest concern and most troublesome skin issue you will treat in multicultural skin types as an esthetician. Hyperpigmentation can take several months to years to see improvements without proper use of lightening agents and corrective skin care treatments. When treating skin of color, daily use of lightening agents or products will have to be incorporated into the treatment program to compliment the treatment modality to effectively eliminate hyperpigmentation. Many of these lightening agents are available in professional skin care products as well as prescription formulas. They are usually applied once or twice a day to help lighten the skin over time. When treating skin of color, lightening agents and treatments can be performed individually or in combination therapy methods to achieve rapid results.
