First, let's set the record straight for the zillionth time. Yes! You should 100 percent absolutely be wearing sunscreen every single day without exception. We'll call it the golden rule of skin care and the number one must-do that just about every medical professional on the planet will stand behind. Get it, got it, good!

But sun protection is hardly our only worry in the world of skin care. To help clear the air on the billions of other skin concerns we are all stressing about, we spoke to top dermatologists to shed light on the most frequently asked skincare questions. Here are your top five skincare questions, answered!

QUESTION: DOES DIET REALLY IMPACT AGING?

"My rule is if it's bad for your waist, it's bad for your face," Marino said. "Inflammation is the skin's worst enemy, and diet can be directly linked to inflammation in the body, which creates flare-ups on the skin."

Dairy, saturated fats, and sugar are known irritants to the gut and directly impact the aging process, specifically refined sugars like those found in processed foods and sweets.

"Once sugar enters the bloodstream, it creates a byproduct called advanced glycation end products (AGEs), which break down proteins in the body, specifically collagen and elastin. Once collagen and elastin are depleted in the skin, you begin to see the breakdown of skin integrity resulting in skin laxity and deep wrinkles at rest," Marino explained. "I recommend my clients to subscribe to an anti-inflammatory diet to keep acne, rosacea, and wrinkles off the radar."

Opt for a colorful diet full of fruits and vegetables in order to power your body and skin with vitamins and antioxidants that will protect it.
