Introduction: Acne scars are largely preventable complications of acne. 95% of the scars occur over the face thus impacting the quality of life. Correction of scars is the priority for acne patients. There is no single treatment modality that has been shown to be universally effective. Microneedling is a relatively new minimally invasive procedure used as a collagen induction therapy for skin rejuvenation and facial scars. Aim of the work: Evaluation of efficacy of microneedling with topical vitamin C in treatment of acne scars. Patients and Methods: Ten patients with post acne atrophic facial scars attending the outpatient clinic of Dermatology in Sohag University Hospitals between June 2014 to September 2017 were offered six microneedling sessions plus topical vit. C (during the session of microneedling and daily topical application in between sessions) microneedling sessions were four weeks apart. They were evaluated monthly and one month after completion of sessions for both efficacy and safety of the procedure. Results: The mean ± SD of the patients' age in the study population were 28.900 ±5.384yers old nine females and one males with mean acne scars duration ± SD 11.900±5.506 years, 90%% of patients had psychological distress from their acne scars. At the end of study duration Out of the ten patients 6(60%) achieved one grade reduction in their Goodman and Baron qualitative grading score and 2 (20%) achieved two grade reduction. According to the quantitative ECCA " Echella d'e valuation Clinique des cicatrices d'acne" score 80% 0f patients achieved reduction in their score with 27.5% improvement in the ECCA score. The mean ECCA score value of V scar started to decrease earlier than both U scar, and M scar. 40% of patients had excellent satisfaction and 60% had very good satisfaction. All treated patients, had adverse events of temporary erythema, edema, bleeding, or a serous ooze resolving with crusting or scabbing following each session of microneedling, bacterial infection not occurred in any of our patients. Conclusion: Multiple minimally invasive sessions of skin microneedling with topical vitamin C during sessions and daily application is an effective treatment for post-acne atrophic scars with the advantage of being a relatively risk-free, in-office procedure with minimal patient recovery time.

Introduction: Acne scars are largely preventable complications of acne. 95% of the scars occur over the face thus impacting the quality of life. Correction of scars is the priority for acne patients. there is no single treatment modality that has been shown to be universally effective. Microdermabrasion (MDA) with infusion; A recent advances in MDA technology combine exfoliation with dermal infusion. During this process, topical products are delivered into the skin at the time of or immediately after exfoliation. Aim of the work: Evaluation of efficacy of diamond microdermabrasion with topical vitamin C in treatment of acne scars. Patients and Methods: Ten patients with post acne atrophic facial scars attending the outpatient clinic of Dermatology in Sohag University Hospitals between April 2018 to September 2018 were offered six diamond microdermabrasion sessions plus topical vit. C (during the session of diamond microdermabrasion and daily topical application in between sessions) diamond microdermabrasion sessions were two weeks apart. They were evaluated at each session and one month after completion of sessions for both efficacy and safety of the procedure. Results: The mean ± SD of the patients' age in the study population were26.00 ±5.81years old nine females and one males with mean acne scars duration ± SD7.45±4.73 years , 80%% of patients had psychological distress from their acne scars. At the end of study duration none of the patients achieved grade reduction in their Goodman and Baron qualitative grading score and 100% of patients had poor (<25%) satisfaction. Conclusion: Multiple diamond microdermabrasion sessions with topical vitamin C during sessions and daily application is an ineffective treatment for post-acne atrophic scars

Introduction: Microneedling is a relatively new minimally invasive procedure involving superficial and controlled puncturing of the skin by rolling with miniature fine needles. Traditionally used as a collagen induction therapy for skin rejuvenation and facial scars specially acne scars. Aim of the work: Evaluation of efficacy of microneedling in treatment of acne scars. Patients and Methods: Ten patients with post acne atrophic facial scars attending the outpatient clinic of Dermatology in Sohag University Hospitals between June2014 to September 2017 were offered six sessions of microneedling at an interval of 1 month. They were evaluated monthly and one month after completion of sessions for both efficacy and safety of the procedure. Results: The mean ± SD of the patients' age in the study population were26.900±5.952years old.eight females and two males with mean acne scars duration ± SD 8.500±6.311 years, 60% of patients had psychological distress from their acne scars. At the end of study duration Out of the ten patients 7(70%) achieved one grade reduction in their Goodman and Baron qualitative grading score while 4 patients (40%) achieved reduction in their quantitative ECCA " Echella d'e valuation Clinique des cicatrices d'acne" score with 8.55% improvement in the ECCA score. The mean ECCA score value of V scar started to decrease earlier than U scar , but M scar was fixed up to end of sessions. 50% of patients had good satisfaction, 30% of them had very good satisfaction and only 10% had excellent satisfaction. All treated patients , had adverse events of temporary erythema, edema, bleeding, or a serous ooze resolving with crusting or scabbing following each session of microneedling but in 1 patient (10%) aggravation of acne occurred, bacterial infection not occurred in any of our patients. Conclusion: Multiple minimally invasive sessions of skin microneedling is an effective treatment for post-acne atrophic scars with the advantage of being a relatively risk-free, inoffice procedure with minimal patient recovery time.
