“…The UVB protection offered by sunscreens is determined worldwide by the in vivo sun protection factor (SPF). For routine daily activities, SPF-30 sunscreen can prevent skin redness and photoaging [15,16]. Nonetheless, most patients usually apply up to 50% of the recommended layer of topical sunscreens on their skin, so products with higher SPF values (e.g., C 50) are recommended for patients with pigmentary disorders [17].…”

“…Protection against UVA is usually determined by the in vivo persistent pigment darkening (PPD) factor. However, different regulatory agencies use various nomenclatures for UVA protection [ 15 ]. As the accomplishment of high PPD values compromises the cosmetic nature of topical sunscreens, the PPD range of 20–30 is indicated in pigmentary disorders to guarantee patient adherence.…”

“…Although VL radiation (especially in the high-energy blue–violet range) can induce melanogenesis, there is still no validated method for assessing the efficacy of sunscreens to protect against this waveband [ 15 , 18 ]. Tinted sunscreens are indicated to protect against VL, while iron oxide salts seem to provide better performance in melasma.…”

Melasma is a prevalent chronic relapsing pigmentary disorder that affects photoexposed areas, especially in women of childbearing age. Although there is currently no curative treatment available for melasma, this manuscript critically reviews the knowledge regarding photoprotection, topical and oral therapies, and procedures such as peelings, laser, and microneedling that represent the main strategies for control and prevention of this disease. As the pathogenesis of melasma is not entirely understood, there are prospects for the development of new therapeutic strategies that might act on the pathways that promote sustained pigmentation rather than merely decreasing melanin synthesis and removing melanin from the epidermis.

“…The detrimental effects of UV rays are both acute (erythema, sunburn, photo‐immunosuppression and photo‐allergy), and chronic (including skin cancers, melasma, post‐inflammation hyperpigmentation and photoageing) 5 . More recently, visible light (400 nm [violet] to 700 nm [red]) and IR radiation (700 nm to 1 millimetre) were identified as contributing factors to photoageing of the skin and skin damage 5–9 . Visible light is involved in worsening pigmentary disorders, such as melasma 5,10 .…”

BackgroundBehavioural interventions can improve attitudes towards sun protection but the impact remains inconsistent worldwide.ObjectiveTo assess awareness of and attitudes towards the multiple facets of sun exposure and suggest ways to improve prevention from overexposure to the sun in all geographical zones and multiple skin types.MethodsOnline survey was conducted from 28 September to 18 October 2021. Study population was selected from the Ipsos online Panel (3,540,000 panellists), aged ≥18 years, from 17 countries around the five continents. Demographics, sun‐exposure habits and practices, understanding of risks and information on phototypes were documented and analysed using descriptive statistics.ResultsEighty‐eight per cent of participants knew that sunlight can cause skin health problems (90% phototypes I‐II, 82% phototypes V‐VI, >90% in American and European countries, 72% in Asia and 85% in Africa). Eighty‐five per cent used some form of protection against sunlight, predominantly: Seeking shade (77%), avoiding the midday sun (66%), facial application of sunscreen (60%) and wearing protective clothing (44%). The perception of sunlight itself is positive (‘it gives energy’ for 82%; ‘tanned skin looks attractive’ for 72%), although less in Asian countries and among individuals with dark skin phototypes. Eighty‐three per cent reported having experienced sunburn, mainly in Australia, Canada, USA, Germany, France and Russia, and among individuals with dark skin phototypes. Only 12% systematically/often used all types of protection during exposure to the sun and 23% believed it is safe to go out in the sun with no protection when their skin is already tanned. From 13% (skin phototype I) to 26% (phototype VI) reported not using any form of protection against the sun. Knowledge and habits were significantly superior among people who are accustomed to seeing a dermatologist for a complete skin exam.ConclusionsDermatologists could play a crucial role in relaying novel prevention messages, more finely tailored to specific risks, populations and areas of the world.
