The use of sunscreens should also be recommended in order to work against all kind of ultarviolet (UV)-induced skin damage such as photoallergies, skin wrinkles, sunburn or even skin cancer. Sunscreens contain chemical filters (organic absorb regularly UVB radiation) and physical filters (e.g., TiO2 and ZnO). The second group has been said to reflect and scatter UVB and UVA radiation. TiO2 is ...
Sunscreen products are among the most important ways for skin protection against sunburn, early skin aging and skin cancer. Due to existing wide variation of sunscreens, it is necessary to assure their protection ability against the sun damage. Performance assessment of sunscreen products against UVA is expressed by sun UVA protection factor (UVA-PF). Because currently these factors are determi...
Background and aim: Saffron possesses a lot of medical applications in traditional medicine. One of its properties is ultraviolet (UV) light absorption. The aim of this study was preparation, determination of properties and investigating sun protevtive effects of nanoliposomes containing saffron extract and safranal, a substance existing in saffron.Methods: Nanoliposomal hydroalcoholic extract ...
Skin cancer is increasing, and prevention programs are essential. This study evaluated the impact of a skin cancer prevention program on sun-protection habits and swimming pool environments. The intervention included staff training; sun-safety lessons; interactive activities; providing sunscreen, shade, and signage; and promoting sun-safe environments. A randomized trial at 28 swimming pools in...
The usage of sunscreens has grown dramatically worldwide over the past decade. Current data suggest that a regimen of sun protection that includes protective clothing, avoiding midday sun, and regular use of broad-spectrum high SPF sunscreen (such as practiced in Australia [19]) seems to be reducing melanoma incidence rates. This is the current recommendation of the American Academy of Dermatol...
Tanning is the increase in skin pigmentmelanin; it causes the change in color of our skin. Excessive tanning causes skin damage. It is overexposure to the UV rays from the sun. The supreme cause of skin cancer is believed to be the over exposure to the solar radiation which is the medley of ultra-violet radiation (UVA, UVB, and UVC), and visible light. UVB is the stronger component amongst the ...
Tabir surya (Sunscreen) merupakan suatu zat atau material yang dapat melindungi kulit dari radiasi sinar ultraviolet (UV). World Health Organization (WHO) merekomendasikan pemakaian tabir sebagai salah satu upaya untuk paparan langsung matahari. Pemilihan harus sesuai dengan jenis kulit. Ketika konsumen dihadapkan banyak pilihan merk, kebanyakan mereka kebinggungan memilih sesuai. Dari masalah ...
Did you know the reason behind wearing sunscreen is more than just preventing a sunburn? Sun damage to skin over lifetime can lead most dangerous type of cancer, called melanoma. Melanoma abnormal growth pigment-producing cells skin, same types that make up moles. Though rare in young people, risk for melanoma increases with age. kids looks and acts differently it does adults, often making diag...
Skin cancer is an increasingly common disease, particularly among young adult women. Sunburn early in life is a risk factor for skin cancer. Few studies have reported on psychosocial correlates of sunburn. The current study consisted of an online survey of undergraduate women from a university in the northeastern part of the USA. A logistic regression demonstrated that young women who reported ...
Titanium oxide (TiO2) nanoparticles are added to sunscreens as they have broad absorbance across the whole UV spectrum. Although photostable, TiO2 nanoparticles can de-excite via surface states giving rise to reactive oxygen species (ROS) formation within the sunscreen formulation. An increased ROS load can degrade organic components within the sunscreen, such as UV absorbers or anti-oxidants, ...
