简要总结
The aim of the study is to evaluate the efficacy and safety of microneedling combined with topical timolol 0.5% in the treatment of atrophic acne scars.
详细描述
Acne vulgaris (AV) is a common chronic inflammatory disease of skin that develops from sebaceous glands associated with hair follicles. Typically AV begins at puberty and may continue through adulthood affecting the comedogenic areas of face, back and chest (Mazzetti et al., 2019).
One of the undesirable outcomes of acne is acne scars that are divided into two main types based on a loss (atrophic) or gain (hypertrophic) of collagen. Atrophic type is the most common type, further subdivided into three subtypes: icepick, boxcar and rolling scar (Bahl et al., 2020).
Post acne scars occur in nearly 75% of patients with acne affecting both male and female equally (Khunger and Kumar, 2012). Acne scars impair quality of life and may be a risk factor for depression, suicide, low academic performance and unemployment (Sood et al., 2020).
There are different therapeutic modalities for atrophic acne scars including microneedling, chemical peeling, laser, filler, surgical procedures (punch excision, punch grafts) and fat transfer (Pavlidis and Katsambus, 2017).
Microneedling is considered safe for all skin types. It is performed by dermapen or dermaroller to induce new collagen formation that remains for a few months after the procedure (Cohen and Elbuluk, 2016).

结局指标
主要结局
Quartile grading system
时间窗: through study completion, an average of 9 months
The improvement of patients is evaluated as follow: Poor (improvement \< 25%) Mild (improvement 26%-50%) Good (improvement 51%-75%) Excellent (improvement \>75%) (Saadawi et al., 2018)
Goodman and Baron's acne scar grading system
时间窗: through study completion, an average of 9 months
Grade 1 Erythematous hypo or hyperpigmented flat marks Grade 2 Mild atrophy not obvious at social distance of \>/=50 cm or easily covered by makeup or beard hair in male Grade 3 Moderate atrophy obvious at social distance of \>/=50 cm, not easily covered by makeup or beard hair but able to be flattened by manual stretching of the skin Grade 4 Sever atrophy obvious at social distance \>50 cm, not easily covered by makeup and not able to be flattened by manual stretching of skin
5 point scale for evaluating patient's satisfaction
时间窗: through study completion, an average of 9 months
None (no satisfaction) Mild (1%-25% satisfaction) Moderate (26%-50% satisfaction) Good (51%-75% satisfaction) Very good (76%-100% satisfaction) (El Domyati et al., 2015)
Pain assessment
时间窗: through study completion, an average of 9 months
Pain during the session will be assessed and graded as mild, moderat and sever (Saadawi et al., 2018).
