Conventional wisdom holds that youth and beauty are priceless, and yet some people are paying a very hefty cost for skin care treatments that promise to reverse aging and renew youthful-looking skin. Anti-aging products shouldn't belong entirely to the domain of the wealthy; everyone should have access to affordable anti-wrinkle serums.\nThe price that people are paying for anti-aging skin treatments isn't only measured in money, however. Some are resorting to medical treatments or harsh chemicals that are not only expensive but may have unpleasant side effects as well. It's not worth the risk of using an unsafe product and risk permanent damage just to look younger.\nFortunately, there are a number of anti-aging serums available that are derived from natural ingredients, contain no harsh chemicals, are safe to use, and cost less than $25. Some are even less than $10. This means that you can now obtain healthier and more youthful-looking skin even if you're on a budget.\nWhat follows is a list of some of the common factors that can age your skin, as well as the best face skin serum or serums under $25 to address each issue.\n1. Dehydration\nPart of the reason that your skin can become dehydrated is because you're not drinking enough water. When your body doesn't receive enough hydration, it is programmed to send what moisture it does have to the vital organs to keep them in operation. When it comes to this internal water rationing, your skin is a fairly low priority.\nHowever, drinking more water alone isn't enough to correct or prevent the effects of skin dehydration, which can include dullness and wrinkles. Your body actually produces a substance called hyaluronic acid that works to hydrate your skin by preventing your skin cells from losing water. Unfortunately, the body's natural production of hyaluronic acid decreases as you get older, meaning that your skin cells can lose more water and your skin becomes less supple and plump as a result. \nA skin serum made from hyaluronic acid helps to make up for the deficit caused by the decreased production in your body. The serum works the same way that the natural hyaluronic acid in your body does to attract moisture to the skin cells and hold it there to increase skin's suppleness and decrease the appearance of wrinkles.\nSqualane is a skin serum that works often works hand in hand with hyaluronic acid to retain skin's hydration. While hyaluronic acid attracts moisture, squalane provides a protective barrier that holds it in place. In addition, squalane lubricates the skin to keep it soft and smooth. \nSqualane is not technically produced by the human body, but it is closely related to a substance that is produced by the body, and performs much the same function, called squalene. Squalene is produced not only by the human body but by certain plants, such as olives, as well as the livers of some shark species. However, it is not suitable for use as an ingredient in face serums because it breaks down when exposed to air. As the human body ages, it produces less squalene.\nSqualane derives from squalene but goes through a chemical process called hydrogenation to make it more stable. When purchasing face serums containing squalane oil, it is important to choose one sourced responsibly from olives or another plant source, as killing sharks to obtain oil from their livers is not environmentally friendly.\n2. Free Radicals \nFree radicals occur when oxygen molecules in the body break down into single atoms. When this happens, electrons in the outer shell become unpaired, and the atom becomes unstable as a result. These unstable atoms look for new atoms to bond with and form a new molecule. The oxidative stress this causes can damage your cells over time and not only contribute to wrinkles and other forms of aging but diseases such as skin cancer as well. The body produces free radicals naturally, but exposure to certain chemicals, such as cigarette smoke, alcohol, air pollution, and pesticides, can accelerate the process.\nAntioxidants are naturally occurring substances that can neutralize the effect of free radicals on the body by donating an extra electron and stabilizing the atoms. You can derive antioxidants by eating certain foods, but you can also counteract the effect that free radicals have on your skin by using serums that contain antioxidants. Vitamin C serum is a completely natural antioxidant that helps to maintain the balance of free radicals in your skin and prevent the damage they can cause.\n3. Hyperpigmentation \nIt is not only wrinkles that make your skin look older. It is also the hyperpigmentation more commonly known as age spots. Exposure to ultraviolet radiation can cause your body to produce more melanin, a skin-darkening agent, to protect vulnerable areas. Sometimes the concentration of melanin is uneven, which is why age spots develop. Vitamin C serum can prevent excess melanin production and lighten dark spots by inhibiting the tyrosinase enzyme in the skin.\n4. Collagen Breakdown\nHowever, vitamin C isn't only valuable to your skin in these respects. It can also help to build up collagen in your skin. Collagen is a protein that provides structure to soft tissues of your body. Collagen in your skin helps give it elasticity. However, as with squalene and hyaluronic acid, the body starts producing less collagen as you age, and your skin can lose elasticity as a result.\nVitamin C serum is one product you can use to boost production of collagen in the skin of your face. Another helpful product is Matrixyl 3000 serum. It contains an alternative ingredient to Retin A, found in many anti-wrinkle formulations, called Matrikines which works to increase collagen synthesis. Matrixyl 3000 also contains hyaluronic acid as an ingredient so that you can hydrate your skin at the same time. \nOur natural skincare line includes these products and more to help your skin not only become more youthful but healthier as well due to increased hydration and other benefits that you can derive from skin serums.
