lasers, ipl and asian skin

This study is investigating the best methods to reduce the hyperpigmentation that can effect asian skin when treated with Lasers or IPL. The paper suggests the use of sun block and bleaching agents pre- and post-operatively can help mitigate against post-inflammatory hyperpigmentation.

Effective and safe use of lasers, light sources, and radiofrequency devices in the clinical management of Asian patients with selected dermatoses, Henry H.L. Chan, University of Hong Kong and Chinese University of Hong Kong, Clinical Insight, Lasers in Surgery and Medicine Volume 37, Issue 3 , Pages 179 – 185, September 2005.

Background and Objectives : The cutaneous application of lasers, light sources, and radiofrequency devices in Asian patients differs in several respects from their use in Caucasians. Asians tend to have more congenital and acquired pigmentary disorders. For example, conditions such as nevus of Ota or Hori’s macules are much more commonly seen in Asian patients. In terms of photoaging, Asian patients commonly present with lentigines and seborrheic keratoses, as opposed to the wrinkling observed in Caucasians. In addition to differences in the disease spectrum, the darker Asian skin type is another important issue. Due to its higher epidermal melanin content, the use of cutaneous lasers, light sources, and radiofrequency devices has often been considered more technically challenging in Asian patients than in Caucasians. This article aims to discuss the effective and safe use of lasers, light sources, and radiofrequency devices in the clinical management of Asian patients.

Study Design/Materials and Methods : The disease spectrum is very different with pigmentary disorders being more commonly encountered in Asian populations. Asian skin, with its higher epidermal melanin content, is more likely to develop adverse reactions, especially post-inflammatory hyperpigmentation (PIH), following treatment.

Results and Conclusions : Recent advances in skin cooling have allowed the development of devices that can achieve skin-type independent deep dermal heating. This development, together with new technologies, such as photomodulation, fractional resurfacing, and intra-dermal focusing, have revolutionized our use of lasers, light sources, and radiofrequency devices in Asian patients. Nonetheless, PIH can occur.

However, by taking the necessary measures, such as the use of sun block and bleaching agents pre- and post-operatively and the appropriate treatment parameters, the risk of PIH can be reduced, allowing the effective and safe use of lasers, light sources, and radiofrequency devices in Asian patients. Future studies that examine the interaction between light sources and the cell cycle will be important in improving therapeutic outcome and reducing adverse effects.

For example, rather than using lasers to induce the thermal destruction of dermal melanocytes, it may be more cost effective with less morbidity to use light sources to heat up the melanocyte to induce premature apoptosis.

Photomodulation is another example of how lasers or light sources could be used to affect cellular function. The development of optical diagnostic equipment is also important to better classify ethnic skin types so that therapeutic outcomes of skin rejuvenation in Asian patients can be improved.

    Any CPT ICD-9 codes for treating rosacea with IPL?

  2. C. says:

    I have acne rosacea and debating with myself to have IPL treatment in a derm office (in US). Considering about the difference between Asian skin and Caucasian skin, what parameters that the derm shall adjust to have a optimal outcome(provided not a damage to the skin)? BTW, I am a Chinese, female. Thanks!
