Photoaging is a process in which ultraviolet radiation damages the normal skin architecture. Topical chemical peeling is used to treat this condition. The authors aimed to understand the mechanism and level of evidence of the different depths of chemical peeling used to treat photoaging. Various topical chemical peelings have been used in cosmetic medicine for many years to treat photodamaged skin. This review compares the efficacy and the level of evidence. This systematic review evaluates the efficacy of different chemical peeling methods. Keywords included “Photoaging,” “Alpha-hydroxy acid,” “Lipo-hydroxy acid,” “Trichloroacetic acid,” “Jessner’s solution,” and “Phenol” were typed on Ovid, PubMed, MEDLINE for relevant studies published on photoaging treatment. There is a wealth of Level I evidence supporting the use of topical retinoic acid, vitamin B, and vitamin C. The evidence behind the use of topical vitamin E exists but is mainly drawn from studies from the Level IV of the evidence hierarchy. Topical vitamins can effectively treat photodamaged skin. Level of Evidence: I

Cheuk Hung Lee(Cheuk Hung Lee),Kar Wai Alvin Lee(Kar Wai Alvin Lee),Kwin Wah Chan(Kwin Wah Chan),Kar Wai Phoebe Lam(Kar Wai Phoebe Lam ) 대한미용의학회 2022 대한미용의학회지 Vol.6 No.2

Acne fulminans is a severe form of acne that has a considerable psychosocial impact. Acne scarring is a potential complication of this condition. The treatment of acne fulminans includes conventional topical antibiotics, systemic antibiotics, hormonal therapy, isotretinoin, and light therapy. Intense pulsed light can have marked effects on acne fulminans. We aimed to describe the treatment of acne fulminans with intense pulsed light. This article is a case report together with a literature review to demonstrate how intense pulsed light can be used to treat acne fulminans. Pre-treatment and post-treatment clinical photographs are provided to show the effects of intense pulsed light therapy on acne fulminans. No comparisons were made with the other treatment modalities; nevertheless, this study provides an alternative treatment option for acne fulminans. Our case report revealed that intense pulse light using multiple filters at certain energy levels can effectively treat acne fulminans. Current evidence suggests that ablative CO2 and Er:YAG lasers provide the best curative effect on acne scars on all skin types. Potential complications with intense pulsed light include pain, burns, and post-inflammatory hyperpigmentation. Intense pulsed light is an effective treatment modality for acne fulminans. However, more cases of acne fulminans treated with intense pulsed light need to be documented in order to affirm intense pulsed light as one of the best options for treating this severe form of acne.

Cheuk Hung Lee(Cheuk Hung Lee),Kar Wai Alvin Lee(Kar Wai Alvin Lee ),Kwin Wah Chan(Kwin Wah Chan ) 대한미용의학회 2023 대한미용의학회지 Vol.7 No.1

Erythematotelangiectatic rosacea is a common, long-standing inflammatory skin disorder of unclear origin. It is characterized by facial erythema involving mainly the central face (malar areas, chin, nasal area, and forehead region), with a range of clinical manifestations varying from blood vessels hyperactivity to sebaceous glands hyperplasia. These can have a considerable psychosocial impact on the patients. Intense pulsed light treatment can have significant effects on severe erythematotelangiectatic rosacea. We aimed to describe the treatment of severe erythematotelangiectatic rosacea with intense pulsed light. This article is a case report together with a literature review to explore the views of researchers on the treatment of erythematotelangiectatic rosacea with intense pulsed light. Pre-treatment and post-treatment clinical photographs are provided to show the effects of intense pulsed light therapy on severe erythematotelangiectatic rosacea. No comparisons were made with the other treatment modalities; nevertheless, this study provides an alternative treatment option for patients with severe erythematotelangiectatic rosacea. Our case report revealed that intense pulsed light using multiple filters at certain energy levels can effectively treat severe erythematotelangiectatic rosacea. We believe that, with more treatment sessions, patients can enjoy longer and more persistent results. Intense pulsed light is an effective treatment for erythematotelangiectatic rosacea. However, more erythematotelangiectatic rosacea cases treated with intense pulsed light will be required to consolidate intense pulsed light as one of the best treatment options for erythematotelangiectatic rosacea. Potential complications with intense pulsed light include post-inflammatory hyperpigmentation, burns, and pain.

Erythematotelangiectatic rosacea is a common, longstanding inflammatory skin disorder with unclear origin. It is characterized by facial erythema involving mainly the central face (malar areas, the chin, nasal area and forehead region) with a range of clinical presentations varying from hyperactivity of the blood vessels to sebaceous gland hyperplasia. It can lead to considerable psychosocial impact. Intense pulsed light (IPL) treatment can potentially have dramatic results on severe erythematotelangiectatic Rosacea. This is a case report of treating severe erythematotelangiectatic rosacea with IPL treatment. Pre-treatment and post-treatment clinical photos were provided to show the effect of IPL therapy on severe erythematotelangiectatic rosacea. This article is a case report together with literature review to explore the view of researchers on erythematotelangiectatic rosacea with IPL. No comparison is made with other treatment modalities. Nevertheless, it provides an alternative treatment option for patients with severe erythematotelangiectatic rosacea.

Laser resurfacing in acne scarring: a review

Lee Cheuk Hung,Lee Kar Wai Alvin,Chan Kwin Wah,Lam Kar Wai Phoebe,Wong Tin Hau 대한미용의학회 2022 대한미용의학회지 Vol.6 No.1

Scarring can complicate acne vulgaris and lead to considerable psychosocial implications. Resurfacing and collagen regeneration treatments for acne scars include cryotherapy, chemical peeling, lasers and lights, and radiofrequency. Lasers have become popular among these options. A range of lasers with varying designs, wavelengths, and fractional technologies have become available as treatment choices for acne scars. This review compares the efficacy and adverse effects of these treatments. This is a literature review to determine whether the use of a combination of laser treatments yields superior outcomes compared to a single-device method in the management of acne scars. Our literature review revealed that patient factors, including Fitzpatrick skin phenotype and acne scar subtype, are essential determinants of outcome success in acne treatment with laser. Evidence suggests that ablative CO2 and Er:YAG lasers provide the best curative effects on acne scars in all skin types. Both non-fractional and fractional techniques can effectively treat atrophic acne scars. However, when using a pulse-dye laser to treat hypertrophic scars, the outcomes are variable. Potential complications of ablative lasers include acne flares, infections, and scarring.
