From an initial 2,218 records, 64 articles comprising 42 clinical trials and 22 experimental studies were selected for inclusion based on their focus on the efficacy, safety, and molecular mechanisms of light-emitting diodes (LED), intense pulsed light (IPL), laser systems, and photodynamic therapy (PDT).<i>Results:</i> Analysis revealed that photo-based modalities target acne through three primary pathways: 1. Sebum Modulation: Aminolevulinic acid (ALA)-PDT demonstrates superior, durable efficacy in moderate-to-severe acne by inducing sebocyte apoptosis and downregulating lipogenesis via the PI3K/Akt/mTOR and OLR1-Wnt/β-catenin pathways. 2. Inflammation Control: Blue and red light (LED) and IPL provide gradual anti-inflammatory effects suitable for mild-to-moderate acne by reducing C. acnes colonization and modulating cytokines such as TGF-β1, IL-10, and TNF-α. 3. Tissue Remodeling: For acne sequelae, fractional CO2 and picosecond lasers promote collagen remodeling to improve atrophic scars, while vascular-targeted lasers (PDL, Nd:YAG) and IPL effectively reduce post-inflammatory erythema (PAE) and hyperpigmentation (PIH).<i>Conclusions:</i> Photo-based therapies are phenotype-specific rather than interchangeable.

However, we have not found studies on photoprotection (topical and/or oral) prescribed in clinical practice.

Of these, 67.8% (61/90) were women, and 83.3% (75/90) worked in public hospitals; 98.9% (89/90) reported always or almost always prescribing sunscreens in cases of photodermatoses. The most important characteristics of sunscreens were: protection against ultraviolet A (UVA) (95.6%) (86/90), against visible light (76.7%) (69/90), and the cosmetic acceptability of the product (67.8%) (61/90); 90% (81/90) reported regularly prescribing a BSSE for photodermatosis, and 60.7% (54/90) claimed that this product was effective or highly effective in reducing symptoms.
