Periocular Rejuvenation by Topical Hyaluronic Acid Nano Particles

Clinical Evaluation of the Efficacy and Safety of Novel Drug-free Hyaluronic Acid Topical Nano-carrier in Periocular Rejuvenation

In this study, The investigators aims to evaluate the efficacy and safety of topical hyaluronic acid nanoparticles as a novel nanodermatological tool in periocular rejuvenation as a replacement approach of invasive dermal filler injections.

Tear trough deformity is a main concern of many people (males or females) with age range of 21 to 65 years old or older. Such condition is characterized by a sunken appearance of the eye that results in an aged and dissipated appearance to the eye.Treatment modalities range from camouflage make up, laser resurfacing, platelet-rich plasma therapy, carboxy therapy, mesotherapy, volume augmentation with injectable hyaluronic acid fillers and fat, as well as surgical procedures such as blepharoplasty. Consequently, safe, effective and less invasive treatment options of the tear trough have remained a challenge. The study will include 30 adult patients (male or female) suffering tear trough deformity. They will be selected from Dermatology Outpatient Clinic of Alexandria Main University Hospital.

patients with tear trough will receive hyaluronic acid nano-gel (2%) 2 applications / day (morning and evening) on tear troughs for 1 month

patients with tear trough will receive placebo conventional gel having the same color, form and packaging for 1 month

To evaluate the efficacy of topical hyaluronic acid nanoparticles in in treatment of tear trough using Sadick et al scale at baseline and after one month treatment. the score will range from 1-14, in which the higher the score, the worse the outcome

Physician assessment will be done at the one-month follow up visit through blinded evaluator-assessed Global Aesthetic Improvement Score. the score will range from 1-5, in which score 1 is associated with best results and score 5 with worst results.

Patient satisfaction will be assessed using a visual analogue scale which is ranged from 0-3, 0 is associated with least satisfaction and 3 with the best satisfaction.

Incidence of side effects will be evaluated at all visits by reporting any adverse events such as erythema, dryness, itching, edema or hyperpigmentation.

To evaluate the efficacy of topical hyaluronic acid nanoparticles in treatment of of dark circles according to the intenisty of pigmentaion (mild, moderate or intense)

To evaluate the efficacy of topical hyaluronic acid nanoparticles in treatment of wrinkles according to Glogau wrinkles scale at baseline and after one month treatment. it ranges from 1-4. one mean youngest and 4 means oldest
