UV radiation and its effects on the skin

Some of the chronic alterations that UV rays cause on the skin are skin cancer, benign abnormalities of melanocytes, and various chronic damages caused by UV radiation in keratinocytes, blood vessels and fibrous tissue, also known as "photoaging" (degeneration of elastic connective tissue of the skin).

The sun and the melanin

Melanin is the most important filter, since it reflects and absorbs some radiation and becomes a sponge of free radicals. What makes every person's defense against the Sun different is the amount of melanin. Types of skin, according to melanin, are called skin types, ranging from I to VI.

Measures of protection

UV radiation from the Sun can be fought through the use of appropriate garments and correctly applying protective sunscreens on the skin. To protect eyesight it is necessary to wear glasses that absorb UV radiation.

It is advisable to use broad-spectrum sunscreens (UVA and UVB rays), and reduce, rather than extend, the exposure to the Sun. If you use sun protection cream, you should choose an SPF according to your individual skin phototype, being aware that it is used to protect yourself from the sun, not to get a tan.

Substances used in sunscreens

BIOLOGICAL FILTERS

Titanium dioxide.
Zinc oxide.
Calcium carbonate.
Magnesium carbonate.
Magnesium oxide.
Iron chloride.

They are antioxidants that prevent the development of radical free and, therefore, enhance the cutaneous immune subsystem. They are being used more and more, particularly in the case of vitamins A, C and E.

CHEMICALS FILTERS

UVB and UVA filters.
PABA.
Salicylates.
Cinnamic acid.
Camphor.
Benzimidazoles.
Benzophenones.
Anthranilate.
Dibenzoylmethanes.

They act by absorbing solar ultraviolet radiation. They capture incidental energy and transform it into another form of energy with a different wavelength, harmless for the skin. Absorbed energy is re-emitted as heat radiation.

PHYSICAL FILTERS

Physical filters or particulate agents (screen substances): they reflect or distort all of the radiation and prevent its absorption into the skin. They protect from UVB and UVA. They act as a mask or opaque makeup to all solar radiation.

UV radiation that strikes the surface is reflected or scattered and does not penetrate into the skin. It is usually composed of mineral pigments.

Active ingredients

-Feverfew extract: decongestant and soothing action. With antiseptic, emollient and anti-inflammatory qualities.

-Oats: Emollient, anti-inflammatory, and energizing. Skin protector. Rich in nutrients, protective, soothing, moisturizing and cleaning factors. It exerts a soothing and decongestant action.

-Glycerin: Maintains hydration. It replaces the moisturizing agents that have been lost by the skin and removes water from the epidermis.

-Vitamin E: contributes to combat aging through its action against free radicals. Antioxidant. Protector of oxidative attacks on skin tissue, protects from the aggressions of UV radiation in exposed skin areas. Prevents premature aging induced by the environment.

-Panthenol: Disinfectant. Calms irritated skin and helps to soften it. Improves and increases the ability of skin to retain moisture. It relieves skin redness and promotes pigmentation.
