There’s nothing that can stop the steady march of time and aging eventually happens to everyone. Have you ever wondered why is it that others age gracefully while others seem to show every year they’ve lived? One reason lies in our genetics – the DNA and other hereditary factors we inherit from our parents and ancestors play a big part. Scientists have been doing genomic testing to explore how differences in genes lead to either younger or older looking skin.
In terms of aging, there are three essential proteins that your skin needs to retain its youth – collagen, elastin, and hyaluronic acid. Collagen binds together vessels and cartilage and in your skin, it’s the matrix that keeps skin strong, plump and firm. Elastin meanwhile helps your skin keep its elasticity and resilience. Finally, hyaluronic acid keeps moisture locked into your skin adding to your skin’s plumpness. When you’re young, your body can produce these proteins as much as you need them. But as you age, your ability to produce these proteins lessen. As you lose these proteins, signs of aging crop up. Lack of moisture dries out skin and makes it look papery and fragile and highlights fine line and wrinkles. Loss of elastin and collagen contribute to sagging.
How can science help? Well, their research in genomics help doctors and dermatologists figure out what ingredients and compounds can positively affect the skin and help curb signs of aging. For example, scientists have found that antioxidants help prevent DNA damage while glycerin helps to add moisture to the skin which is why these two compounds are often found as key ingredients in skin care products. Carotenoids are another type of helpful compound which help reverse sun damage by inhibiting the growth of melanocytes and melanoma cells thus fighting against pigmentation disorders. A cluster of amino acids known as peptides meanwhile have the very important function of creating collagen.
Topically applied give your skin a healthful and youthful glow as well as act as anti-aging defense mechanisms due to their ability to inhibit protein-destroying enzymes. Vitamin C is a nutrient that has
long been associated with anti-aging. It is an anti-oxidant with collagen synthesizing properties that make it a gem for fighting signs of aging. So the next time you’re out shopping for your creams and lotions, take a few minutes to read the ingredients on the package and look for these compounds so you can be sure that your skin benefits from the careful research done by scientists and doctors.
