Laser skin resurfacing has become a popular therapeutic modality for the correction of acne scars, but it is not always effective in all types of acne scars. Non-ablative dermal remodeling has gained acceptance in the treatment of atrophic scars and has a role especially in rolling and shallow boxcar scars. With respect to ice pick and deep boxcar scars, ablative lasers are the better treatment choice [72].
Blepharoplasty

A lower eyelid blepharoplasty is more frequently performed for cosmetic reasons alone and may also involve the removal of skin and muscle alone or this may be combined with the removal and/or repositioning of herniated orbital fat, the resuspension of a ptotic orbicularis oculi muscle, a lateral canthal suspension, an orbital decompression procedure for thyroid eye disease or a midface or suborbicularis oculi fat (SOOF) lift. It may also be combined with skin-rejuvenating procedures (e.g. laser skin resurfacing, a chemical peel or the post-operative injection of dermal fillers).
Laser skin resurfacing

Interest in skin rejuvenation has seen a marked increase over the past few decades. Whereas ptotic facial tissue may demand a rhytidectomy or blepharoplasty, signs of sun damage (photodamage), scarring and hyperpigmentation can be treated relatively effectively with skin resurfacing. Treatments available include topical retinoids and chemical peels, dermabrasion and laser resurfacing. Of these, laser skin resurfacing offers the patient the greatest, often dramatic, clinical improvement and new technology has increased its availability and acceptability.

Acne scarring is a very frequent dermatologic complaint in daily practice that causes cosmetic and psychological problems. Laser skin resurfacing has greatly improved the results of atrophic acne scars treatment. However, acne scarring still remains a therapeutic challenge for dermatologists and may need combination treatment in many affected patients (14). Ablative laser resurfacing via CO2 or Er:YAG lasers have an improvement rate of 25% to 90% for improving acne scars and is still regarded as the “gold” standard. The high rate of postoperative erythema, infection, scarring, and pigmentary squeal are the main obstacles for their extensive use (18). Postoperative hyperpigmentation is frequently encountered in patients with darker skin types even though it often disappears spontaneously (5). Alternatively, different nonablative lasers are now available and found to improve acne scar appearance. These results are attributed to their ability to enhance collagen synthesis and the accompanying dermal remodeling. The results of these types showed improvements of 40% to 50% in scar appearance. Short downtime and a low risk of side effects balance for the lower improvement results of these laser devices (19).

From March 2015 to June 2017, 25 patients (15 males, 10 females) with atrophic acne scars were selected for this study. The mean age was 23.7 years (range 18–35). The patients’ Fitzpatrick skin type classification ranged between III and IV. The exclusion criteria included the following: patients with diabetes, malignancy, connective tissue disease, immunodeficiency, active inflammation, ablative or nonablative laser skin resurfacing within the preceding 12 months, mental disorder, treatment area with metal implants, heart pacemakers or automatic defibrillator implantation, a history of keloid scar formation, coagulation defects and platelet count＜ 100 × 106／L, hemoglobin concentration ＜110 g／L, taking anticoagulants or antiplatelet agents within the preceding 6 months.
A randomized, single-blind, study evaluating a 755-nm picosecond pulsed Alexandrite laser vs. a non-ablative 1927-nm fractionated thulium laser for the treatment of facial photopigmentation and aging

Laser toning performed by non-ablative lasers is commonly employed to eliminate dyschromias, fine lines, sun spots and textural irregularities. Unlike traditional laser skin resurfacing treatments that have harsh side effects and require prolonged downtime and recovery, laser toning using new generation non-ablative lasers has dramatically increased in popularity due to their safety, efficacy and minimal downtime required after treatment (1–3). These devices treat skin photoaging through selective photothermolysis and rely on thermal-induced tissue response for any tissue change. With the development of nanosecond and picosecond pulse durations, quality switched (QS) lasers, including the QS Nd:YAG, QS alexandrite and QS ruby lasers, have been regularly used in the treatment of these epidermal/dermal pigmented lesions. Intense-pulsed light (IPL) devices and fractional photothermolysis devices also provide nonablative skin treatment options for cutaneous photodamage and have been studied for the treatment of photoaging (4–6).
