So if you read Part One of our talk with certified dermatologist Dr. Doris Day, you know that too much exercise can start to have premature aging effects on your skin.

"Exercising is hard enough without the added stress of aging.  It requires motivation, inspiration and commitment. You shouldn't have to choose between being fit and looking good," Dr. Day said. We agree!

Here are some things the expert says you can do to look your best starting now:

The Best for Runner's Face. "Depending on where you are losing the most volume, hyaluronic acid fillers such as JUVÉDERM XC and JUVÉDERM VOLUMA XC can effectively restore lost volume and support the areas that have fallen due to impact," the physician said.

The Best for Tired Looking Face. An at-home spa experience with the Environ Intensive Revival Masque is just want the doctor ordered! "This luxurious, rich moisturizing masque is specially formulated to target signs of aging, including uneven, dry and photo-damaged skin,"Dr. Day explained.

"It will also provide skin with the hydration it needs to achieve a smoother, younger and more refined appearance." Price? $81.

The Best for Skin Revitalization. Dr. Day says that in-office treatments like peels and the PicoSure® Laser, the first FDA-approved picosecond laser, can help treat any hyperpigmentation and revitalize skin for a more youthful complexion. Try it for $300 - $1000.

The Best for Preventing Sun Damage. "Love working out outdoors, but forget to put on sunscreen? "A preventative measure like wearing Innovative Skincare Extreme SPF30 sunscreen is important to prevent further sun damage," Dr. Day recommended. Get this formula for $68.

The Best for Hair Protection. Take down that tight sporty ponytail and give strands some TLC. Dr. Day suggests with Keranique Follicle Boosting Serum. "This utilizes peptides, stem cell technology and Keratin Amino Complex to strengthen and fortify thinning hair, help thicken each hair shaft, and repair the outer protective layer and repair split ends." Try it for $30.
