Poly-L-lactic acid (PLLA) is a biostimulatory filler approved for use in HIV lipoatrophy as well as cosmetic improvement in facial folds and wrinkles in immunocompetent patients. Similar to the face and hands, the décolletage is commonly subject to photodamage and the resulting appearance of rhytids and crepiness, which could benefit from PLLA treatment.


The objective of the study was to assess the safety and efficacy of injected PLLA for the improvement in rhytids and crepiness of the décolletage.


In this open-label, prospective, interventional study, 25 healthy female volunteers aged 40-to-70 years with moderate-to-severe crepiness and wrinkling of the décolletage were injected with 1 vial of PLLA at each of three treatments. The Fabi-Bolton 5-point chest wrinkling scale was used by both investigators and subjects to assign pretreatment and post-treatment follow-up scores at 1 month, 3 months, and 6 months. Adverse events were reported at each visit.


All post-treatment mean scores had statistically significant improvement compared to the pretreatment baseline means as rated by both investigators and subjects. At 1 month following the last treatment, compared to baseline, investigators rated 83% of subjects had improved by at least one point on the scale. Subjects rated 74% of subjects improved by at least one point. At 6 months, 90% of subjects, as rated by the investigators, and 57% of subjects, as rated by the subjects, had improvement from baseline.


PLLA is safe and effective for improvement in the rhytids and skin quality of the photodamaged décolletage.
