 In this episode of Derms and Conditions, Dr James Q. Del Rosso welcomes esteemed dermatologist Dr Henry Lim from Michigan. Together, they explore the evolving science behind photoprotection, the importance of advances in sunscreen formulations and ingredients, and the clinical relevance of sunscreen formulations that both protect against and repair photodamage. Dr Lim provides an update on comprehensive photoprotection that includes ultraviolet radiation coverage, recognizes the growing role of visible light protection, and incorporates ingredients with antioxidant activity. He also explains where mineral sunscreens can be particularly helpful in clinical practice. A major part of the discussion highlights the progression of science supporting DNA repair through the use of liposomes containing photolyases. These enzymes have been shown to repair cyclobutane pyrimidine dimers—mutagenic DNA lesions induced by UVA and UVB exposure. Incorporating photolyases into sunscreen formulations has been associated with reduced actinic keratosis formation and enhanced skin protection. Dr Del Rosso shares his insights on ISDIN's Eryfotona Actinica and Eryfotona Ageless, two mineral sunscreens that include photolyase-containing liposomes, also known as DNA Repairsomes®, to enhance natural DNA repair processes. Each product contains additional active ingredients offering distinct benefits for specific patient needs. Dr Del Rosso and Dr Lim discuss how these formulations fit into both preventive and reparative strategies, particularly for patients with a history of actinic damage or elevated risk for nonmelanoma skin cancers. The conversation then covers the value of broad-spectrum protection, lightweight formulations, and patient education to encourage consistent use. Dr Lim offers practical pearls on counseling patients, improving sunscreen adherence, and integrating these strategies into everyday dermatologic care. They also touch on the importance of photoprotection in skin of color, emphasizing the need for inclusive clinical research and personalized recommendations. Dr Lim reinforces the importance of year-round sun protection, even for individuals who perceive themselves to be at lower risk. The episode wraps up with forward-looking insights into the future of photoprotection, including emerging technologies and formulation innovations that may reshape dermatologic sun care. From thoughtful commentary to evidence-based guidance, tune in for the latest in photoprotection—just in time for summer.
