All of us want healthy, smooth, and blemish-free skin that glows. Most of us spend hours in search of good solutions to our skin problems. Some of us are fortunate with better skin and thus don’t have to worry too much, but some of us are not so lucky. Many women go through a lot of trouble just to figure out a suitable skin care routine using the products that are easily available to them. What most of us don’t realize is that it is not all about using many products, rather I say the less products we use, the better off we are. We should emphasize on bettering our health and body and thus improving our skin. This way, we’ll use a few products to assist the well-being of our skin, not using products to ‘fix’ our skin. I have written about the negative effects of Sodium Lauryl Sulfate on skin and the reasons behind avoiding it. I have also written about my skin care routine that has successfully worked for me. Today, I will be writing about vitamins C and E – I have done some research on what has been found scientifically and I will present my finding to you. Hopefully this will show you why may choose (or not) to improve your diet for better health and skin.
A research group based out of Universität Witten-Herdecke, Germany found that carotenoids ( b caretonoids) and carotenoids ( b caretonoids) along with vitamin E can protect against UV-light induced erythmia in human skin. The scientists gave b caretonoids and b caretonoids with vitamin E supplements to groups of healthy volunteers (6 men and 14 women) to be consumed orally for 12 weeks. These volunteers were divided into two groups and the scientists defined two skin types. Skin type I were fair, white skin; red or blond hair; green or blue eyes; extremely sensitive to sun exposure, and had an absence of tanning. Skin type I were white skin; blond or light brown hair; blue eyes; sensitive to sun exposure, and had nominal tanning. The scientists performed their research from blood analysis and skin color measurements that they collected from the volunteers. After the analysis, they conclude that volunteers who consumed caretonoids ( b caretonoids to be exact) plus vitamin E exhibited less erthyema formation. The antioxidant properties of vitamin E along with b caretonoids protect the skin. Lastly, the scientists pointed out that it takes at least 10 weeks for one to notice any positive change from consuming b caretonoids and vitamin E; a shorter consumption period might not show positive results.

The second research was conducted by a group of scientists at the University of Liverpool, UK. The difference between the above-mentioned research and this research is that the first research gave the volunteers b caretonoids and b caretonoids plus vitamin E; on the other hand, this research gave sixteen research subjects either a -tocopherol (a form of vitamin E) OR b -carotene, not both vitamins. The sixteen research subjects were healthy; 8 of them were men and 8 were women; between the ages of 18-27 years, and with skin type II (fair skin; light brown/chestnut hair; green/hazel eyes; sometimes tans/usually burns) or skin type III (light olive skin, chestnut hair, hazel eyes, usually tans/sometimes burns). With the subjects’ consent, “A fixed UVR dose of 120mJ/cm2 was given to a 1-cm diameter site on buttock skin. The irradiation source was a fluorescent broadband lamp (TL12; Philips Lighting, Guildford, United Kingdom) that emitted UVR between 270 and 400 nm (peak emission: 310 nm). Irradiance was measured with an IL1400A radiometer (International Light, Newburyport, MA), and doses were expressed as erythemally weighted UVR. Two 4-mm skin punch biopsy samples were taken from the UVR- exposed site at 6 h after exposure, together with 2 control biopsy samples from adjacent nonexposed buttock skin.”
The subjects were randomly divided into two groups; they took either a -tocopherol OR b -carotene for 8 weeks. After that, their skin samples were analyzed biochemically and a skin erythema assessment was completed as well. After analyzing all the tests and the statistical results, the research group concluded that a -tocopherol or b -carotene has no effect on skin sensitivity to UVR.
