Acne scar correction using calcium hydroxylapatite in a carrier-based gel

Area of Science:

• Dermatology
• Aesthetic Medicine
• Regenerative Medicine

Background:

• Acne scars represent a significant challenge in dermatological treatment.
• Existing treatments for acne scars have varying efficacy and potential side effects.
• Calcium hydroxylapatite (CaHA) is a biocompatible filler with potential for scar treatment.

Purpose of the Study:

• To evaluate the efficacy and safety of calcium hydroxylapatite filler for acne scar treatment.
• To assess the longevity of results from calcium hydroxylapatite filler in acne scars.

Main Methods:

• A cohort of ten subjects with diverse acne scar types received calcium hydroxylapatite filler injections.
• Treatment outcomes were assessed over a 12-month period post-injection.

Main Results:

• Calcium hydroxylapatite filler demonstrated efficacy in improving saucerized acne scars.
• Ice-pick acne scars did not show significant improvement with calcium hydroxylapatite filler.
• Treatment benefits persisted for at least 12 months in responsive scar types.
• No major adverse events or treatment complications were reported.

Conclusions:

• Calcium hydroxylapatite filler is a safe and effective option for long-term correction of saucerized acne scars.
• The study highlights the differential response of acne scar types to calcium hydroxylapatite filler.
• Calcium hydroxylapatite filler offers a durable solution for specific types of atrophic acne scarring.
