Review
INTRODUCTION
Skin disorders associated with photodamage from ultraviolet light include wrinkles, hyperpigmentation, tactile roughness, and telangiectasia, and are more common in people with white compared with other skin types. Wrinkles are also associated with aging, hormonal status, smoking, and intercurrent disease.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of interventions to prevent and treat skin wrinkles? We searched: Medline, Embase, The Cochrane Library, and other important databases up to April 2008 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 20 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: carbon dioxide laser, chemical peel, dermabrasion, facelifts, glycolic acid, isotretinoin, lactic acid, natural cartilage polysaccharides (oral or topical), retinyl esters, sunscreens, tazarotene, tretinoin, variable pulse erbium:YAG laser, and vitamin C or E (topical).

Review
INTRODUCTION
Acne is a common condition that can result in permanent scarring. Acne scars can be broken down into three categories: atrophic; hypertrophic; and keloidal. Atrophic scars can be further sub-classified into: ice pick; rolling; and boxcar.
OBJECTIVES AND METHODS
We have performed a comprehensive literature search of the last ten years in order to determine the efficacy and adverse reactions of commonly used treatments against post-acne scarring.
RESULTS
A total of 36 relevant articles were identified on the following interventions: subcision (n = 10), dermabrasion (n = 1), microneedling (n = 8), dermal fillers (n = 5), and chemical peeling (n = 12).
DISCUSSION
Improvement in the appearance of post-acne scarring following subcision is in the range of 10-100%. Microdermabrasion achieved the least significant results. A total of 27.3% patients did not achieve any benefit despite eight treatment sessions, and only 9.1% achieved good results. All patients treated with microneedling achieved some improvement in scar appearance in the range of 31-62%. Dermal fillers also led to favourable outcomes. In particular, treatment with PPMA led to improvement in 84% of patients. Utilising chemical peels, trichloroacetic acid (TCA) CROSS achieved >70% improvement in 73.3% of patients, whereas 20% glycolic acid did not lead to any improvement in 25%.
CONCLUSION
Post-acne scarring is a common and challenging condition with no easy and definitive solution. The above interventions have been used with varying degrees of efficacy, each having both pros and cons. All have been deemed to be safe with few and transient adverse reactions. However, further trials with a larger number of patients are necessary in order to reach more concrete conclusions regarding their efficacy.
