A wonderful sunny day could really change our mood, it allows us to better face daily routine and enjoy the outdoor benefits! A sunny day brings us back to positive thinking, energy, beauty and health. However, we should not forget all the implications of sun-exposure, in order to benefit from sunlight avoiding the related risks, caused by solar over-exposure. Let’s better understand what sun exposure really implicates, knowing that uneven solar exposure can cause not only tiny sunburns, but also it could increase incidence of certain forms of skin cancer.
Sunlight is composed by different bands characterized by their wavelength (λ) and energy: a portion of such radiation is represented by ultraviolet (UV) rays
- UVC rays (λ = 40 ÷ 286 nm) are filtered off by atmosphere ozone and they don’t reach Earth surface in considerable amount.
- UVB rays (λ = 286 ÷ 320 nm) stimulate melanin formation even though they penetrate only partially through skin, and are the main responsible for suntanning. They act superficially on epidermis and can damage skin cells, determining inflammation and sunburns, due to their high energy.
- UVA rays (λ = 320 ÷ 400 nm) represent the majority of UV radiation, they deeply penetrate through skin and cause damage to underlying tissues, they provoke skin ageing and contribute to pathologic phenomena. They also give rapid suntan using the already-formed melanin.
Sunscreens: an important protection for our skin
Cosmetic sunscreens play a major role in skin safety, they represent a strong defence for our skin and contribute to effectively protect it from sunlight.
Since September 2006 European Commission has set directives for a perfect solar protection formulation: it must screen efficaciously from both UVA and UVB rays. EU directives compel cosmetic manufacturers to display clear labels in terms of efficacy and claims of sun-care products. BeC, as a cosmetic manufacturer, has been working seriously to assure the best performance of sun-care products, with the added value of the essential oils, the emollient, soothing and antioxidant actives that play a key role for comprehensive sun protection. They sooth erythema, while blocking skin photo-aging, beside cutting off UV rays.
BeC sun-care products are based on a careful combination of the best photostable sunscreen (physical and chemical) in order to assure complete coverage of the UV spectrum.
The special formulation and the efficacy testing on human volunteers assure a totally safe and perfect suntan. To this aim, the sunscreen of Creme solari (SPF 6, 15 , 30 e 50+) covers the full protection range so to perfectly match your specific photo-type. Special attention is devoted to deliver super-fine and even dispersion of the UV-filter in the formula, so to assure a uniform protection and suntan. Ingredients’ quality, mostly from natural origin
(100% natural in case of SPF6) makes these products fully skin-compatible, suitable also for the most delicate skin-types.
As we anticipated, BeC sun care products are not only made of sunscreens! Along with natural components which stimulate melanogenesis (ATP, tyrosine and riboflavine – vit. B2), making suntan more rapid and intense, i.e. aiding skin self-protect, BeC sun care products are rich of hydrating and soothing actives, which nourish our skin and contribute to re-equilibrate physiologic skin moisture and elasticity.
Daily use of BeC suncare products avoid damages caused by sun over-exposure but also effectively increase hydration and elasticity!
Natural Vitamin E contained in every BeC sun care product helps prevent wrinkle formation and premature skin ageing along with defending skin from the action of free radicals involved in radiation mediated inflammatory processes.
BeC sun care line acts by preventing sun damages: this is especially the case for the oil Huile SolÈ® that is particularly rich in vitamin E. Efficacy tests have shown that daily use reduces already formed wrinkles by 12% in only one week of treatment! This is an outstanding result!
BeC sun care products are designed to let us enjoy full benefits from sunlight, while reducing risks and side effects such as allergies, photo-sensitization and skin ageing. In order to protect skin from harmful radiation, our careful sun care formulation stimulates natural skin defence and guarantees a perfect and uniform suntan leaving hydrated, elastic and silky skin.
The soothing action on irritation and the prevention of risks associated to free radicals – that causes premature ageing – complete the special properties of our sun care line.
Let’s benefit from a good suntan without turning down an excellent solar protection!
Let’s better know which sunscreen are allowed in EU in cosmetics, according the Regulation (EC) No 1223/2009 of the European Parliament and of the Council of Europe:
- para-aminobenzoic (PABA) acid derivatives screen UVB rays with absorbance maximum peaks between 285 and 310 nm.
- Cinnamates (e. ethylhexyl methoxycinnamate) are able to protect from UVB rays behaving also as quencher of excited species produced by solar radiation. They absorb radiation at maximum wavelength around 310 nm.
- Benzylidencamphor derivatives screen UVB rays and are quencher as well.
- Dibenzoylmethane derivatives protect from UVA rays.
- Benzophenones absorb both UVA and UVB rays.
- Salicilates boast a moderate absorbing efficacy in UVB region, with absorbance maximum at around 305 nm.
- Triazines, i.e. Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine, are excellent photo-stable sunscreen covering the wide range of UVA and UVB.
- Diphenylcyanoacrilates, i.e. Octocrylene represent a good wide range UVA-UVB sunscreen.
- Titanium bioxide and Zinc oxide represent physical sunscreen characterized by full UV-range coverage and reflecting action with sunlight scattering properties.
