Six-Month Safety Results of Calcium Hydroxylapatite for Treatment of Nasolabial Folds in Fitzpatrick Skin Types IV to VI

Abstract

People with dark skin injected subdermally with CaHA do not show signs of keloid formation, hypertrophic scarring, or hyper- or hypopigmentation. Because of this safety feature, as well as other characteristics of the product already shown in clinical literature, CaHA is an attractive dermal filler in this population.
