Sun effects upon Rosacea
Vitamin D can come from sunlight with about fifteen minutes twice per week without sunscreen. And even better if every day for three or four minutes per day. Of course, do not pick the heat of the day but early mornings or late evenings. The 'sunshine vitamin' comes from ultraviolet rays without sunscreen. And it can be very very therapeutic and stress releasing to go for a walk, shopping and of course spending most of the time inside the shops. The two to three hours shopping can be enough sunshine gained in the fifteen minutes or so per day that is incidental can be enough. And of course the best the best way to gain the maximum benefit is to work in your yard with shorts and a very light shirt or blouse allowing sun rays to come through when the sun is at a 45 degree at 7:30 AM to 10:00 AM as it is also cooler than 4:00 to 7:00 PM. And the ultimate is still sun bathing with the sun rays can hit all of the body and again in the early morning for less heat. However, a friend sun bathing with you can add much dimension to the sun bather. Yet sometimes sun bathing alone can be very beneficial to release stress.

Avoid over exposure to the sun whenever possible. Though sunlight is important for production of Vitamin D, most of us receive a healthy amount of sunlight in our daily chores. There are many harmful effects of sun over exposure. Be aware that some drugs will increase sun sensitivity. Particularly, sunlight can be a factor in Ocular Rosacea.
Sunscreens
Effective rosacea treatment and skin care involves preventing skin damage. The use of sunscreens is just one of these skin care measures when in the sun for more than 20 to 30 minutes during the heat of the day.
Sunscreens are designed to protect against sunburn (UVB rays) and generally provide little protection against UVA rays. UVA rays have a depressing effect on the immune system, and are therefore a "setup" for other dermatological problems such as rosacea. Sunscreens work by reacting chemically with the skin cells to protect them from the UVB rays of the sun. Unfortunately for those who suffer with rosacea, the ingredients in protective sunscreens can actually cause a sunburn-like photosensitive reaction. This reaction includes a rash or itchy rash that can persist for days giving an appearance similar to rosacea. Studies by the Australian Journal of Dermatology indicate that 81% of the reactions caused by photosensitive persons were caused by two primary ingredients- oxybenzone and butyl methoxydibenzoyl methane.
Sunscreens come in two forms
Chemical sunscreens contain chemicals such as benzophenone or oxybenzone (benzophenone-3) as the active ingredient. They prevent sunburn by absorbing the ultraviolet (UVB) rays. Most chemical sunscreens contain from 2 to 5% of benzophenone or its derivatives (oxybenzone, benzophenone-3) as their active ingredient. Benzophenone is one of the most powerful free radical general known to science. It is used in industrial processes to initiate chemical reactions and promote cross-linking. Benzophenone is activated by ultraviolet light. The absorbed energy breaks benzophenone's double bond to produce two free radical sites. Most chemical sunscreens cause various degrees of redness and sensitivity to rosacea sufferers. Staying out of the sun is the best answer. Please do not worry about the incidental 10 to 50 minutes in the sun, especially early in the morning and late afternoon, but if you have to be out in the sun during the heat of the day or for long periods, wear a hat, if possible, and a sun block or sunscreen. CityBlock by Clinique (SPF 40) provide the most blockage and the least irritation and sensitivity. CityBlock can be purchased online and in the skin care department in stores worldwide.
Physical sunblocks contain ingredients such as zinc oxide, sodium chloride, magnesium stearate, polyethylene glycol, iron oxide, and sulfur. Please Note: You may possibly consider comparing these physical sunscreen ingredients with the ingredients of Rosacea-Ltd IV. The ingredients function by reflecting the ultraviolet (UVA and UVB) rays away from the skin. These physical natural minerals as a sunscreen are preferable for rosacea patients. Also, you can gain further sun protection by applying the chemical sunscreen over the 'physical sunscreen' which helps to keep the skin from being irritated by the chemical sunscreen.
Sun Rays - Ultraviolet Radiation
UVA rays constitute 90-95% of the ultraviolet light reaching the earth. They have a relatively long wavelength (320-400 nm) and are not absorbed by the ozone layer. UVA light penetrates the furthest into the skin and is involved in the initial stages of suntanning. UVA tends to suppress the immune function and is implicated in premature aging of the skin.
UVB rays are partially absorbed by the ozone layer and have a medium wavelength (290-320 nm). They do not penetrate the skin as far as the UVA rays do and are the primary cause of sunburn. They are also responsible for most of the tissue damage which results in wrinkles and aging of the skin and are implicated in cataract formation.
UVC rays have the shortest wavelength (below 290 nm) and are almost totally absorbed by the ozone layer. As the ozone layer thins UVC rays may begin to contribute to sunburn and premature aging of the skin.
All forms of ultraviolet radiation are believed to contribute to the development of skin cancer, and likewise cause havoc for the rosacea patient.
Skin Cancer - There are three major forms of skin cancer caused by sun rays
Basal Cell Carcinoma is the most common form of skin cancer. It occurs most frequently in men who have "high sun exposure" and primarily produces lesions on the head and neck. Basal cell carcinoma rarely spreads throughout the body but can invade neighboring bone and nerves.
Squamous cell carcinoma is the second most common skin cancer. It primarily affects people who "sunburn easily, tan poorly, and have blue eyes and red or blonde hair". Squamous cell carcinoma most commonly develops from actinic keratoses and can metastasize if left untreated. Squamous cell carcinoma of the lip is 12 times more common among men than among women.
Malignant Melanoma is the rarest form of skin cancer but is the most deadly. This YouTube Video may be scary for you, while improving your knowledge and being helpful for your future and of some one you care about. It affects the cells which produce melanin and seems to be more prevalent among city-dwellers. So City dwellers will please consider using "CityBlock by Clinique (SPF 50" as mentioned above and a good 'physical sunblock'. It does not necessarily occur on sun-exposed areas of the body and is thought to be linked "to brief, intense periods of sun exposure, and a history of severe sunburn in childhood or adolescence." Malignant melanoma metastasizes easily and is often fatal if not found early.
