Photoaging highly impacts your anti aging skin care regimen as well as the effects of the beauty creams you use to even out your skin tone and prevent wrinkles. Photoaging is a premature aging accelerated and caused by repeated exposure to the ultraviolet radiation coming from the sun and also, from artificial UV sources. The early signs of photoaging are the appearance of spider veins on the nose, cheeks, and neck. A general loss of skin tone in the sun exposed areas may develop along with the freckles and liver spots. Continued sun exposure can make your skin look leathery with visible broken blood vessels on the nose and cheeks. The skin begins to sag too.
About 90% of the skin aging problems are due to the effects of the sun’s UV. Photoaging can be avoided unlike the natural aging process. With a good sun protection, you can repair the mutations caused by the sun’s UV, if not, the affected cells may die.
The lips oftentimes show excessive damage. The rays of the sun can damage the collagen and elastin as well as the epidermal cells. Photoaging is very visible on the sun exposed parts of the body, such as the arms, legs, and shoulders.
Anti aging skin care photoaging protection
You can protect yourself against photoaging and cancer by using an SPF sunscreen of at least 15 SPF. Natural sunscreens should be applied frequently, especially during swimming and when sweating.
A study about the human epidermis interaction between the skin and the sunscreen SPF found the natural sunscreen products can effectively absorb the UVR of the sunrays. An application of the best natural sunscreen product can best help reduce the level and intensity of the skin exposure from the UV carcinogens.
The study investigated the effects contributed by the UVR to the skin, which includes a range of cellular as well as molecular changes. The WHO recognized UVR as a form of carcinogen that directly causes cancer.
The damage caused by the severe sunburn can lead to skin cancer due to the excessive exposure from the UVR. In the United States alone, there were over a million cases of skin cancer diagnosed every year. The Skin Cancer Foundation reported the melanoma as one of the deadliest forms of disease.
Studies determined that the UVR exposure may lead to developing the melanoma. About 8,000 people in the US die of melanoma. You can stop and prevent photoaging by using sun protection measures, such as limiting sun exposure and avoid getting sunburned.
Do you know the regular use of the sunscreen during your first 18 years of life may help reduce incidence of cancer by as much as 78%? Even one serious childhood sunburn incident can increase your risk of developing the malignant melanoma and further, into skin cancer. The rays of the sun are considered as complete carcinogen that produces skin carcinogen.
During the early stages of skin carcinogenesis, the skin usually undergoes DNA damage that involves cell cycle arrest, apoptosis, and mutation or neoplastic transformation.
A DNA lesion removal and cellular repair may be required to avoid the formation of a cyst or tumor. The UVR triggers a DNA damage that may lead to photocarcinogenesis.
The use of natural sunscreen inhibits the skin from the UVR DNA damage. It also protects you from developing other diseases associated with the skin cancer.
Natural sunscreen products are designed to absorb the ultraviolet light of the B wavelength. This process prevents the B wavelength from penetrating the skin. However, if possible, maintaining a minimal exposure to the sun can be most helpful in preventing the onset of the disease.
Enjoying your tan under the direct heat of the sun is not healthy anymore and should be reconsidered for primary health reasons. Bed tanning using an artificial UV light is not recommended as an alternative.
The SPF-15 sunscreen with 7.5% ethylhexyl methoxycinnamate and 4.5% benzophenone-3 can reduce the solar simulated human skin pyrimidine dimers. The best prevention for photoaging is to put some sunscreen when you expect a heavier sun exposure. The SPF-10 natural sunscreen protects you from the pyrimidine dimers that often results from a UVB exposure.
There are 3 main categories of skin cancer
- Basal cell carcinoma
- Squamous cell carcinoma
- Malignant melanoma
Among the three categories, the malignant melanoma has been considered as the most dangerous. Melanoma starts developing on the epidermal surfaces constantly exposed to the sun. This condition spreads quickly to other portions of the body.
When you detect skin lesions looking like pigmented moles on your skin, you should immediately consult a doctor. These pigmented moles can change in shape, size, and color over time. You may feel some itchiness or notice little bleeding.
Stay out of the sun during the period when it is most intense. If it is unavoidable due to occupational requirement, you can use sunscreen, umbrella, wide brimmed hat, and wear sun protective clothing. Too much damage and delayed treatment can make photoaging irreversible. Unlike sunburn and suntan that disappears after a few days, the photoaging develops over time or through years without being noticed. It undergoes both internal and external changes.
Prolonged UV exposure can impair the skin’s immune system resulting in a lessened ability to heal wounds. The skin immune cells decrease significantly and weakens its ability to resist skin cancer. Wearing sunglasses protects the skin around the eye and also decreases the risk of eye damage.
