safe Your Skin from Summer Sun with the Right Supplements

Summer approaches...Plan Ahead

Ultraviolet (Uv) rays on unprotected skin can cause first and second degree burns to the skin, commonly referred to as sunburn. Long-term damage from overexposure can contain premature aging and even skin cancer. The use of commercially available sunscreens with an Spf of 15 or higher is effective protection. However, a variety of natural remedies may be even more helpful than chemical-laden oils.

Protective nutritional supplements

Research has identified the benefits of antioxidants to preclude or minimize injury caused by Uv radiation. Damage begins when Uv radiation stimulates the production of free radicals and lipid peroxidases within the skin. Antioxidants such as vitamin E and vitamin C neutralize these particles and curtail cellular damage. These base nutrients are also effective for sunburn prevention.

In a study at the University of Munich, 10 subjects were given Vitamin C (2000 mg) and Vitamin E (1000 Iu) daily or a placebo. The sunburn reaction before and after 8 days of supplement use was determined by measuring the minimal erythema (redness) dose, or Med. This is the whole of Uv radiation significant to create a uniform pink color on exposed skin.

The results showed that subjects taking the vitamins required 20% more Uv radiation to experience the same level of reaction as compared to those taking a placebo(1) . A similar corollary came from a isolate study at the University of Frankfurt, terminal that vitamin C and vitamin E act synergistically to suppress a sunburn reaction.(2)

Another supplement, beta-carotene, has been studied for effects as a sun protectant. Data published from study at the University of Arizona suggests that supplementation with natural carotenoids 90 mg daily for 24 weeks conveys modest protection from both Uva- and Uvb-induced erythema.(3)

Taking these three supplements daily for a week before a going on a beach vacation, or taking them throughout the summer, could be a wonderful, safe way to safe yourself from sunburn.

Healing Topical Therapies

Natural topical therapies have been shown to be helpful for sunburn. A study from the University of Western Ontario showed that application of 5% Vitamin E cream immediately after a sunburn significantly decreased necrosis of the skin's keratinocytes, commonly referred to as "peeling." This positive corollary was noted even when the application was delayed up to 8 hours after exposure.(4) This is very good news for those that observe in the evening that their over-exposure occurred earlier in the day.

A variety of herbs been reported to have soothing effects. Applying the oil from sea buckthorn (hippophae rhamnoides) 3 to 4 times per day has been useful as both a natural a sunscreen or as a sunburn therapy. Sea buckthorn oil is a natural product that contains vitamin C, malic acid, flavaniods, carotenoids, and significant fatty acids. These constituents safe cells from lipid peroxidation injury.(5) Interestingly, the oil combine has been used to treat radiation burns caused by radiation therapy and on bedsores. Sea buckthorn increased the rate of new skin formation and compel the formation of granulation tissue in wounds.(6) Other herbs useful for the topical rehabilitation of sunburn contain 5-10% jojoba extract,(7) jujube oil,(8) and a semi-solid preparation of 20-30% dried poplar buds.

Beware of Herbal Photosensitizers

Consumers need to be aware of inherent complications, such as photosensitivity, linked with both natural and pharmaceutical products from only moderate sun exposure. St. Johns Wort (hypericum perforatum) can cause photosensitization when taken orally at 1800 mg/day for 15 days (9) and can cause phototoxicity at a dose of 0.5 mg/kg per day, albeit that is a rather large dose.(10) Photosensitization has been observed from both topical and large consumption of herbs that create from plants that belong to the Apiaceae family.(11) The farranging list of base spices and vegetables from that plant family includes parsley, wild carrot, parsnip, anise, coriander, fennel, lovage, bishop's weed, angelica root, pimpinella root, guta kola and dong quai. Interestingly, eating base figs (Ficus carica) may also cause photodematitis in sun-sensitive persons.(12) Patients should be reminded that the use of positive medications are also known to cause photosensitivity, such as sulfa and tetracycline.

A Final Note

Lack of exposure to sun can cause significant condition problems too. Sunshine on the skin converts 7-dehydrocholesterol to pre-vitamin D, which is supplementary processed by the kidneys into 1,25-dihydroxyvitamin D, the active form of the vitamin. A New England Journal of rehabilitation description reports that almost one-third of men and half of women over the age of 60 are deficient in vitamin D, the nutrient significant to maintaining condition bones.(13) Spending 20 to 30 minutes in full sunlight, without sunscreen, three times a week, will allow the body to produce the much-needed vitamin D.

A very recent study published in the American Journal of Clinical cusine states that vitamin D is not toxic at intakes much higher than previously determined unsafe. "This risk estimation was needed to show that newer evidence supports the conclusion that vitamin D is much safer then previously thought, particularly because of all the emergence research that shows advantage for vitamin D at higher levels than consumers were traditionally taking," lead author John Hathcock told NutraIngredients.com. In fact, the Council for Responsible cusine scientists state that this could be raised to 10,000 Iu (250 micrograms per day). (14)

Using base sense in the sun moderate exposure and an awareness of potentially phototoxic herbal remedies will go along way to promote good condition for your skin and make summer fun a delightful experience instead of an eventful one.

safe Your Skin from Summer Sun with the Right Supplements

Summer approaches...Plan Ahead

Ultraviolet (Uv) rays on unprotected skin can cause first and second degree burns to the skin, generally referred to as sunburn. Long-term damage from overexposure can include premature aging and even skin cancer. The use of commercially ready sunscreens with an Spf of 15 or higher is productive protection. However, a range of natural remedies may be even more helpful than chemical-laden oils.

Protective nutritional supplements

Research has identified the benefits of antioxidants to forestall or minimize injury caused by Uv radiation. Damage begins when Uv radiation stimulates the yield of free radicals and lipid peroxidases within the skin. Antioxidants such as vitamin E and vitamin C neutralize these particles and curtail cellular damage. These common nutrients are also productive for sunburn prevention.

In a study at the University of Munich, 10 subjects were given Vitamin C (2000 mg) and Vitamin E (1000 Iu) daily or a placebo. The sunburn reaction before and after 8 days of supplement use was determined by measuring the minimal erythema (redness) dose, or Med. This is the whole of Uv radiation primary to create a uniform pink color on exposed skin.

The results showed that subjects taking the vitamins required 20% more Uv radiation to palpate the same level of reaction as compared to those taking a placebo(1) . A similar effect came from a cut off study at the University of Frankfurt, final that vitamin C and vitamin E act synergistically to suppress a sunburn reaction.(2)

Another supplement, beta-carotene, has been studied for effects as a sun protectant. Data published from study at the University of Arizona suggests that supplementation with natural carotenoids 90 mg daily for 24 weeks conveys modest protection from both Uva- and Uvb-induced erythema.(3)

Taking these three supplements daily for a week before a going on a beach vacation, or taking them throughout the summer, could be a wonderful, safe way to protect yourself from sunburn.

Healing Topical Therapies

Natural topical therapies have been shown to be helpful for sunburn. A study from the University of Western Ontario showed that application of 5% Vitamin E cream immediately after a sunburn significantly decreased necrosis of the skin's keratinocytes, generally referred to as "peeling." This safe bet effect was noted even when the application was delayed up to 8 hours after exposure.(4) This is very good news for those that peruse in the evening that their over-exposure occurred earlier in the day.

A range of herbs been reported to have soothing effects. Applying the oil from sea buckthorn (hippophae rhamnoides) 3 to 4 times per day has been beneficial as both a natural a sunscreen or as a sunburn therapy. Sea buckthorn oil is a natural product that contains vitamin C, malic acid, flavaniods, carotenoids, and primary fatty acids. These constituents protect cells from lipid peroxidation injury.(5) Interestingly, the oil merge has been used to treat radiation burns caused by radiation therapy and on bedsores. Sea buckthorn increased the rate of new skin formation and hasten the formation of granulation tissue in wounds.(6) Other herbs beneficial for the topical medicine of sunburn include 5-10% jojoba extract,(7) jujube oil,(8) and a semi-solid preparation of 20-30% dried poplar buds.

Beware of Herbal Photosensitizers

Consumers need to be aware of potential complications, such as photosensitivity, connected with both natural and pharmaceutical products from only moderate sun exposure. St. Johns Wort (hypericum perforatum) can cause photosensitization when taken orally at 1800 mg/day for 15 days (9) and can cause phototoxicity at a dose of 0.5 mg/kg per day, albeit that is a rather large dose.(10) Photosensitization has been observed from both topical and large consumption of herbs that create from plants that belong to the Apiaceae family.(11) The allembracing list of common spices and vegetables from that plant family includes parsley, wild carrot, parsnip, anise, coriander, fennel, lovage, bishop's weed, angelica root, pimpinella root, guta kola and dong quai. Interestingly, eating common figs (Ficus carica) may also cause photodematitis in sun-sensitive persons.(12) Patients should be reminded that the use of safe bet medications are also known to cause photosensitivity, such as sulfa and tetracycline.

A Final Note

Lack of exposure to sun can cause primary condition problems too. Sunshine on the skin converts 7-dehydrocholesterol to pre-vitamin D, which is supplementary processed by the kidneys into 1,25-dihydroxyvitamin D, the active form of the vitamin. A New England Journal of medicine article reports that almost one-third of men and half of women over the age of 60 are deficient in vitamin D, the nutrient primary to maintaining condition bones.(13) Spending 20 to 30 minutes in full sunlight, without sunscreen, three times a week, will allow the body to furnish the much-needed vitamin D.

A very new study published in the American Journal of Clinical nourishment states that vitamin D is not toxic at intakes much higher than previously determined unsafe. "This risk assessment was needed to show that newer evidence supports the windup that vitamin D is much safer then previously thought, particularly because of all the emergence study that shows benefit for vitamin D at higher levels than consumers were traditionally taking," lead author John Hathcock told NutraIngredients.com. In fact, the Council for Responsible nourishment scientists state that this could be raised to 10,000 Iu (250 micrograms per day). (14)

Using common sense in the sun moderate exposure and an awareness of potentially phototoxic herbal remedies will go along way to promote good condition for your skin and make summer fun a delightful palpate instead of an eventful one.
