Does photorejuvenation have a rebound effect?

In general, photorejuvenation does not typically cause rebound effects, but its results may gradually diminish over time. Photorejuvenation is a non-invasive skin treatment that uses light of specific wavelengths to illuminate the skin, stimulating collagen regeneration in the deeper layers of the skin and improving skin texture and appearance. It is commonly used to address skin concerns such as pigmentation spots, redness, fine lines, and enlarged pores.

The effects of photorejuvenation are not permanent. After treatment, skin condition will show noticeable improvement, but over time, natural aging and environmental factors—such as ultraviolet radiation and unhealthy lifestyle habits—can cause the effects to gradually fade. Usually, the results of photorejuvenation can last between 6 to 24 months, with the exact duration varying from person to person depending on individual skin condition, the number of treatments received, and post-treatment care.

If proper daily sun protection is neglected after treatment, or if the skin continues to be exposed to strong ultraviolet radiation, pigmentation or other skin problems may reappear, which can be considered as "rebound" to some extent. Therefore, it is important to strictly follow the doctor's advice after treatment, enhance sun protection measures, use sunscreen with a high SPF value, and avoid prolonged exposure to strong sunlight.
