What factors contribute to hyperpigmentation after laser treatment?

Hyperpigmentation after laser treatment is predominantly influenced by skin type and post-treatment sun exposure. Different skin types possess varying levels of susceptibility to pigmented lesions and can react differently to laser therapies. For instance, individuals with darker skin tones have a higher propensity for experiencing hyperpigmentation due to the greater amount of melanin present in their skin.

Post-treatment sun exposure significantly contributes to hyperpigmentation as the skin may be more sensitive and vulnerable to ultraviolet (UV) rays after undergoing a laser procedure. It is essential for patients to diligently adhere to sun protection measures following treatment, as UV exposure can trigger melanin production, leading to unwanted pigmentation changes.

Other factors, such as age, diet, or adherence to post-treatment instructions, may play roles in overall skin health and recovery but are not as directly linked to the phenomenon of hyperpigmentation in the aftermath of laser procedures. Additionally, the type of laser used might influence outcomes, but the specific interactions of skin type and sun exposure are more pivotal in understanding hyperpigmentation.
