Sunscreen: Use It or Lose It!

By Peachy

Most people are well-aware that sunscreen is an incredibly important tool in the fight to prevent skin cancer. Even if SPF had no other benefits, that would be reason enough to use it religiously. That said, it also provides wrinkle prevention benefits. By protecting your delicate facial skin from the sun’s rays, daily-use sunscreen helps combat photo-aging, or aging due to sun damage. In fact, sun exposure is responsible for 80% of facial aging! Once you’ve acknowledged that SPF should be a part of your daily skincare regime, the next step is to choose the sunscreen that works best for you. We can help with that, too!

Beyond Just Prevention

As mentioned above, the majority of facial aging is caused by sun exposure and the resulting photodamage. Ultraviolet (UV) exposure upregulates the proteins in the body that degrade collagen. This means your time in the sun leads to decreased skin elasticity and contributes to the overall aging of your skin. Sun exposure can also lead to patchy hyperpigmentation, sunspots, and rough skin texture. Sunscreen acts as a protective barrier, shielding your skin from both the short-term and long-term effects of UV exposure and in doing so can help prevent photoaging of your skin. Recent studies have even shown that the benefits of daily-use sunscreen extend beyond that of prevention. In a trial, researchers found that by using SPF 30 every day, participants saw significant reversal in existing photodamage after as little as 12 weeks. By the end of the study, 100% of subjects saw improvement in skin clarity and texture.

Sunscreen, the Safe Way

Ultimately, we firmly believe that the best sunscreen is the one you wear. If there is an SPF product you already love and are committed to using daily, keep it up! If you’re still searching for the perfect product, we recommend that you reach for a sunscreen that uses physical filters, such as zinc oxide or titanium dioxide. A recent study published in the Journal of the American Medical Association tested the systemic absorption levels of six chemical actives commonly found in sunscreens. The end result was that all six chemical filters were found in plasma at concentrations exceeding FDA recommendations. The clinical effect of these concentrations is still unknown and requires additional research. By using physical filters, rather than chemical filters, you’ll know you’re relying on ingredients that have been proven safe by the FDA.
