Intradermal Delivery of Calcium Hydroxylapatite With Fractionated Ablation.

This observational pilot study demonstrates that CaHA, a collagen stimulator used as a dermal filler, can not only be inserted into the dermis after fractional laser treatment but remains in the healing skin for at least 6 weeks posttreatment. The noninvasive imaging techniques RCM and MPM successfully captured the presence of CaHA microspheres mid-dermis during the healing phase. They also demonstrated new collagen production around the microspheres, highlighting the effectiveness of these imaging approaches in monitoring such treatment over time.
