A common debate rages in the beauty world: Do toners play a critical role in a skin care regimen or are they an unnecessary step in the cleanse-tone-moisturize process?

Let me set the scene: I'd just bumped into designer Jason Wu backstage at his New York Fashion Week show and was on my way to the bathroom. Feeling rather encumbered by my oversized camera bag — not to mention tired after a day of marching around NYC to hit as many shows as possible — I was very much looking forward to finding a moment of quiet refuge behind the fancy toilet stall door at The St. Regis Hotel.

Applying sunscreen and reapplying throughout the day is essential, but it shouldn't be your only line of defense against the sun's harmful, aging rays. UPF clothing is a great way to stay protected, especially in times of prolonged sun exposure.

With temps expected to surge this weekend, you're probably looking for ways to stay cool. Sure, you can break out the cutoffs and your favorite strappy tank or a flirty summer dress, but the best way to avoid overheating is with a chill hairstyle.

Selecting the right beauty products in the summer can be somewhat tricky, as the heat and humidity can definitely make choosing your go-to moisturizer, skin care and even fragrance a real challenge. We consulted top beauty experts (think celebrity makeup artists, waxing pros and dermatologists) to share the products they'd actually use themselves when the week-long heatwaves become practically unbearable. Here are some of the beauty products they recommend adding to your arsenal asap.
