Polyhydroxy Acid (PHA)
Overview
Polyhydroxy acids are a class of gentle exfoliants that help improve skin texture and hydration without causing irritation. They are particularly beneficial for sensitive skin types.
Clinical Evidence
Integrated Skincare Active Ingredients
The use of polyhydroxy acids in integrated skincare has been highlighted in the study titled International Expert Consensus on Integrated Skincare Active Ingredients for Pretreatment and Posttreatment Use With Medical Aesthetic Procedures to Enhance Skin Benefits. This study emphasizes the importance of selecting appropriate active ingredients for various aesthetic procedures, noting that PHAs can be safely used during the healing phase due to their low irritation potential.
Scalp Treatment Regimen
In another study, polyhydroxy acids were assessed for their efficacy in treating scalp conditions. The research titled An Assessment of the Safety, Efficacy, and Tolerability of a Novel Scalp Treatment Regimen Combining a Hydroxy Acid-Based Scrub and Copper Tripeptide Serum in the Management of Seborrheic Dermatitis in Adults demonstrated significant improvements in scalp health and hydration, showcasing the benefits of hydroxy acid derivatives in dermatological treatments.
Acne Management
Furthermore, polyhydroxy acids play a role in acne management, as discussed in the article Role of Trifarotene in the Management of Acne in Indian Patients: Insights From an Indian Dermatology Experts' Meeting. Their gentle exfoliating properties can help reduce acne lesions while minimizing irritation, making them suitable for various skin types.
Conclusion
Polyhydroxy acids are versatile ingredients that enhance skin texture and hydration while being gentle enough for sensitive skin. Their inclusion in skincare regimens can lead to improved outcomes in both aesthetic procedures and dermatological conditions.
