What are the risks and side effects of photorejuvenation?

In general, photorejuvenation is a non-invasive skin beautification technique that primarily improves skin texture and tone through the application of intense pulsed light (IPL) at specific wavelengths. It can stimulate collagen regeneration, reduce fine lines, acne marks, pigmentation, and minimize pore size, thereby achieving skin rejuvenation. However, there are potential risks, mainly including skin dryness, pigmentation, skin burns, vascular damage, and increased skin sensitivity.

Photorejuvenation may cause skin dryness. During treatment, the light energy may irritate the stratum corneum and affect the skin's ability to retain moisture, resulting in dryness. Photorejuvenation may also lead to skin pigmentation or hypopigmentation. Individuals with darker skin tones may experience temporary darkening of pigmentation, while others may develop lightened pigmentation. These changes are mostly temporary, although in rare cases they may persist for longer periods.

If the treatment energy is too high or the procedure is improperly performed, it may cause skin burns, scar formation, or even thermal injury. The occurrence of such complications is closely related to the skill level of the physician, the quality of the equipment, and postoperative care. Photorejuvenation can effectively improve visible vascular conditions such as telangiectasia (redness and broken capillaries). However, improper operation may cause vascular damage, leading to local bruising or more severe complications. After treatment, the skin may become more sensitive and prone to UV damage.

Prior to undergoing photorejuvenation treatment, it is important to consult a qualified physician to understand the risks and potential complications. Additionally, choosing an experienced practitioner and a reputable medical facility for treatment, as well as following the physician's post-treatment care instructions, can help minimize the occurrence of adverse effects.
