[C371]Cerave Skin Moisturizing Cream

Most people think about caring for their skin more in the summer when the sun is hot than in the colder winter months, but cold can also dry out your skin since you tend to sweat less. However, the summer brings with it the harmful ultraviolet rays of the sun to a greater or lesser degree depending on your climate. Tough leathery skin is generally associated with skin neglect by white skinned people in the hotter areas of the world such as Australia and the southern parts of Florida and California.

You should look after your skin since it is important to you. It not only keeps everything inside that should be kept inside, but also generates vitamin D and contains the temperature control system that your body relies upon. Elephants flap their ears, dogs pant and humans sweat! Without your skin you would be in a bad way, so you should look after it. If you don't keep it supple it gets dry and hard, wrinkled, itchy and can crack, into which the bugs and viruses needed to make you ill can enter.

All of this occurs when your skin loses its moisture. In order to keep it in tip top condition, and keep yourself looking young and attractive, you should keep it moist through the use of artificial moisturizers if necessary. So why does your skin dry out and how do moisturizers work to help overcome the effects of drying?

In fact the major problems that occur with your skin due to exposure to sun in the summer have nothing to do with drying out. Your skin actually does, as suggested above, become more affected by dryness in the winter when the relative humidity is low. It is in winter that you have to use lip moisturizer because of dry and cracked lips, not summer. However, summer has its dangers, even more than winter.

It is the UV radiation from the sun that damages your skin and can ultimately lead to skin cancer. The UVA and UVB radiation are at different wavelengths and have different effects. The combination, however, causes wrinkles, skin disorders when aging, premature aging, and dry leathery skin. Part of this is believed to be due to the breakdown of the collagen in the skin that maintains its elasticity, free radical damage and inhibition of the immune system.

When UV radiation breaks down collagen it causes the accumulation of abnormal tissue. When this builds up, enzymes are produced that are intended to repair the collagen, but sometimes it does not work properly and produces a disorganized and random accumulation of collagen fibers that eventually result in wrinkles.

Free radicals are chemicals that have a free electron available, rather than having all electrons in pairs as in stable compounds. It is therefore unstable and will steal an electron from healthy tissue and so damage the cell that it takes it from. Eventually, the cells die and genetic material within the cells can be altered. This can cause wrinkling of the skin and underlying tissues or even cancer by changing the DNA and RNA contained within the cell.

The final defense of the body against cell damage is paradoxically apoptosis, which is suicide by the damaged cells to prevent them becoming cancerous. This is what you see when your skin peels after sunburn ? it is deliberate action on behalf of the cells of your skin sacrificing themselves to save the body as a whole. UV exposure can prevent this from occurring which is why it can lead to some forms of skin cancer.

However, it is the action of oxidants on the skin that cause most damage. The so-called drying out of skin is largely due to oxidant damage more so than to loss of moisture. The sweat glands in your skin can produce lots of moisture, but nothing can be done about free radicals other than provide the help of antioxidants to kill them off. Antioxidants destroy free radicals with glee, and hunt them down wherever they are. The common antioxidants in your body are vitamins A, C and especially the powerful vitamin E. That is why so many skin creams contain vitamin E, and sometimes also vitamin A.

However, there are many more antioxidants than these. Astaxanthin is one. ?Asta what?? I can hear you say, and I am not surprised. It is not very common in health stores, but has been approved by the FDA and in Europe as a food colorant. It is a terpene carotenoid, though does not break down to vitamin A in the human metabolism as other carotenes do. It is claimed to be fifty times more powerful as an antioxidant than vitamin E and acts as an internal sunscreen in the skin by blocking the harmful effects of UV radiation at cellular level.

It is available naturally in krill, salmon, trout, crustaceans and some bird feathers, and is extracted from microalgae. Not all sources are palatable and it is best taken as a supplement, or to protect the skin, in a cream. Another super-antioxidant is pycnogenol. However, be aware of purchasing it under this trade name in the USA, since the term has been hijacked by others who are selling a different product under that name. The true chemical pycnogenol as named by Frenchman Dr. Masquelier is a very strong antioxidant: any others are mere imitations that are not the same product.

Chemically, pycnogenol is a proanthocyanidin, a flavanol extractable from grape seed or pine bark. Any product that comes from a different source cannot be pycnogenol. That said, the product is able to strengthen the skin and prevent wrinkles through its effect in scavenging free radicals. It stops the free radicals from destroying the cells of the skin and causing premature aging. Whether the chemical is extracted from pine bark or grape seed appears to make no difference. The chemicals are virtually identical, or should be if they are from the right form of pine bark.

The polyphenols in green tea also eradicate free radicals. They too are very strong antioxidants, just one of the remarkable properties of this plant. However, none of these will be of much help unless specifically applied to the skin. If taken internally, they will do a great job of mopping up free radicals in the blood, but very little will actually reach the skin.

In order to build healthier skin, you will have to use antioxidant rich skin moisturizing lotions that apply moisture to your skin, but more importantly also apply these powerful antioxidants. If you really want to maintain good looking wrinkle-free supple skin in sunny climates, then look for one or more of the above substances as an ingredient in your moisturizing lotion.
