Sunscreen and Dietary Antioxidants Can Prevent Skin Aging

Are you getting tanned? Then, you are exposed to UV radiation and increase your risk of skin cancer. Skin cancer represents more cases than breast, prostate, uterus, colon pancreas, and ovarian cancers combined. Most of the 1 million non-melanoma skin cancers are sun-related, according to the American Cancer Society.

If skin cancer does not persuade you to use sunscreen, maybe vanity will. In the past, the only scientific evidence of anti-wrinkle benefits of sunscreen was in hairless mice. Today, Australian researchers found out that the sunscreen can do more than protect your skin from sun damage.  When used all year round, the research indicated that there is an increased reduction of wrinkles after 4.5 years than those who used less, according to a senior scientist at the Queensland Institute of Medical Research, Adele Green.

The study revealed that daily use of sunscreen shows less skin aging on different parts of the body, including the face. Everyone can benefit from this product regardless of skin color, age, sex, skin cancer history, among others. The study used SPF 15 sunscreen, and Green added that anything stronger may have beneficial effect. The SFP 15 can block the 94% of UVB rays, while SPF 40 about 97.5 percent. The important issue is to apply the product and reapplying it properly. Dr Thomas Ruenger, professor of dermatology at Boston University adds that using a broad-spectrum sunscreen is better because most products blocks only UVB rays. Both UVB and UVA rays can penetrate deep into the skin causing premature aging.

Why Slather on Sunscreen

Sunscreens reduce but do not completely protect your skin to damaging UV rays. If you wear SPF15 sunscreen in the sun for 15 minutes is equivalent to one-minute baking without any protection.  The titanium dioxide or zinc oxide in sunscreens may provide a barrier between your skin and the UV rays. Don’t think a cotton T-shirt is the way to go either because it will only provide SPF5 protection.

According to FDA, sunscreen is an important component of a daily protection plan. Many people choose to go out and wear protective clothing; the product is a good alternative to protect the skin from sun damage, skin cancer, and premature aging. Broad-spectrum sunscreen can protect the skin from both UVA and UVB. As most products indicate protection from UVB (type of UV that causes sunburn) alone, reading the label will help you make informed decisions about the better protection from both UV rays. Study shows that with routine use, it can prevent freckles.

How can Sunscreen Reverse Aging?

Before the study, there is a lack of scientific evidence that the use of sunscreen and dietary antioxidants can prevent skin aging. Recently Australian researchers conducted the study to prove that theory. The study enrolled randomly selected 913 adults 55 years old and below and were assigned to four groups.  The first group used a broad-spectrum sunscreen and 30 mg of beta carotene The other groups have daily use of the product and placebo, discretionary use of the BSS and beta carotene, and placebo, 30 mg of beta-carotene and optional use of sunscreen.

The result revealed that the group with daily sunscreen use showed no detectable increase in skin aging after 4.5 years. Skin aging baseline at the end of the study was 24% less in the everyday sunscreen group, and the beta carotene has no effect in skin aging, although slight improvements were seen in contrasting associations with severity of baseline and aging. Overall, regular and proper sunscreen use is effective in retarding skin aging in healthy middle-aged women and men. The study also indicated that with  daily use, it can even reverse skin aging of up to three years.
