Does Melanin Work Being a Natural Sunscreen During Tanning?
Melanin is what many dark-skinned people want to have a smaller amount of, although white-skinned people want more.
Melanin may be the pigment that gives our hair, skin and eyes their color. It is produced, with the skin, but in addition in several internal organs.
The truth is, Melanin plays more roles in the body than coloring.
In many Asian countries, it comes with an abundance of cosmetic products with all the promise to really make the skin lighter along with countries using a most of fair-skinned population, cosmetics which gives a darker skin-color, are often very popular.
This post, however, is focused on how Melanin supports the procedure for tanning.
In a nutshell, tanning (if done efficiently) increases the production of Melanin for the protection of cells towards over-exposure from Ultra-Violet (UV) light.
This is one way the tanning process energizes the manufacture of Melanin and makes it darker:
1. The UVB-component in sunlight (or in the lamps in a tanning bed) stimulates the Melanocytes-cells inside the outer skin-layer (epidermis) to create more Melanin.
2. The UVA-component in Sunlight (or from your lamps in a tanning bed) oxidizes the newest and also the already established Melanin to some darker color.
3. The now darkened Melanin forms a barrier across the cells within the body and uses its black or dark brown color to diffuse additional UVB-rays that may be harmful.
The brown Melanin molecules also move towards the very outside of the skin in order to form one more barrier towards over-exposure from UV-light. And, voila, you've created your own body's natural sun-protection and also had a very healthy tan.
Now you understand the basic role of Melanin from the tanning process, let's look into what could hinder natural means of Melanin creation and protection.
The most common interference is caused by chemicals in sun-screen cosmetics. The goal of such chemicals is always to block the UV-rays from reaching the body. They do this by forming the diffusive or reflexive barrier onto the skin. It's a good plan to utilize sun-block chemicals in case you suddenly find yourself the need to spend long periods of time in strong sunlight.
The challenge generally sun-protection lotions is, however, that they often block just the UVB-component in sunlight. Thus they let from the UVA that may still oxidize your existing Melanin and give you a surface tan. The UVA will also enhance the photo-aging of your skin. However, because the UVB-rays are blocked, your body will not likely create any extra Melanin as well as your natural UV-protection will not likely increase.
Another reason because of not using sun-screen is really because by blocking the UVB, your system will probably be denied all of its opportunity to create Vitamin D.
Generally, I do not believe it is just a great idea to eliminate, by unnecessary use of sun-screen cosmetics, the fragile balance between UVB, UVA and Melanin which has evolved within your body for numerous years.
Another source of interference is always to try and enhance the body's natural production of Melanin.
The two most common chemicals just for this are Psoralen and Tyrosine. Both are meant to raise the coming of Melanin nevertheless they get it done in quite other ways.
Psoralen boosts the photosensitivity of the skin by making it more receptive to UV-light. It sometimes can be handy in medically supervised treatments of skin-conditions for example psoriasis, it's not recommended as a method to build more Melanin to get a darker tan.
Tyrosine, conversely, could be the main amino-acid that this melanosomes inside melanocytes uses to generate Melanin. The decision remains to be on if topically applied tyrosine (the industry common ingredient in tanning lotions) does indeed improve the output of Melanin inside the skin. Whatever the case, tyrosine seems to be the best bet if you need to assist the job of the melanosomes to make more Melanin.
Lately, another substance has emerged claiming to add to your bodys Melanin storage.
The unapproved and untested Melatonan is attributed both to provide a chemical tan that could help to prevent skin-cancer, in addition to prevent impotence problems. My view on Melatonan is niagra is simply another attempt through the pharmaceutical industry to profit from the sun-scare hysteria created by themselves as well as their peers within the chemical sunscreen industry. Additionally, using the added attractiveness instead of Viagra, it'll probably be a big-seller.
Our preferred sun-protection method is to help you my body's natural production of Melanin by regular and moderate tanning. If the natural sun is not enought above for UVB to achieve planet earth (or once the temperature is bad), I personally use tanning beds with tubes emitting an affordable amount of UVB.
My experience is not that only does this method keep my degree of Vitamin D with a consistent healthy level, it generates for me a natural sun-protection, corresponding to no less than SPF 15, once i travel for the vacation to a sunny place.
I actually do use tanning lotions according to Natural aloe-vera or coconut-milk with plenty of added natural antioxidants as well as other skin-caring ingredients. Tyrosine is frequently a part of those tanning lotions.
These lotions definitely help me to help keep my skin moisturized, young and smooth and capable to absorb sunlight from the most effective way.
A final thought, you may be believing that I have forgotten DHA (Dihydroxcyacetone) from the report on Melanin-stimulators? Then you should know that the one purpose of DHA (and its particular cousin, Erythrulose) in tanning-lotions is to oxidize the already existing and dead Melanin for the outer skin-layer in a darker color. Thus DHA won't influence a mans manufacture of Melanin.
