Why does the sun cause premature aging? Answering that question requires a basic understanding of ultra violet rays. There are a few different UV rays that reach the skin: UVA and UVB. UVA rays are what cause your skin to tan, however, this can also lead to wrinkles and other signs of ageing. Additionally, UVB rays cause sunburn, due to the melanin in the skin being unable to fully absorb this specific UV ray. UVB rays that also cause skin cancer.
Repeat overexposure to UV radiation leads to a variety of skin issues, including: fine lines, wrinkles, sun spots, freckles, melisma, actinic keratosis, and many more. Fortunately, there are preventive steps that can help to protect skin from the UV rays. Applying high quality sunscreen such as Elta MD is Dr. Vallecillos’s number one recommended solution.
The Benefits of Elta MD
Normally, I have a list of “cons” to give patients about a product, but when it comes to Elta MD sunscreen, I don’t have any. It’s all benefit.
Many people fail to wear sunscreen on their face because they claim to not like the way it feels (greasy, oily, heavy, take your pick). Others feel that they can’t wear makeup over their sunscreen, typically for the same reasons (greasy, oily, etc.). Of course, if you grab a tube of sunscreen off the drugstore shelf, these complaints are probably valid. Those products, while valuable, are meant to withstand extended time in the water or sweating outside. For that reason, they tend to be thick and heavy.
Elta MD Clear, though, is just that – clear. It’s oil-free, with a lightweight, silky feel. You can wear it with or without makeup, or buy a tinted version to use in place of foundation. With SPF 46, it helps prevent sunburn and decreases your risk for skin cancer as well as signs of premature aging. Further benefits include:

Health Benefits of Sunscreen
Over time, patients experience increasing amounts of UV damage as they age, which may lead to other potential health risks. As the skin is the largest organ in the human body, continuous exposure to sun rays often lead to issues later in life. Sunscreen is the key towards protecting from future signs of aging, including:
- Immune changes
- Impaired ability to heal wounds
- Damage to the DNA itself, leading to cellular senescense (when healthy cells cease dividing) and carcinogenesis (the formation of cancer cells)
