How to transition your skin-care routine from summer to fall, according to experts

Dry air can really dehydrate your skin. To keep it at bay, use a really hydrating moisturizer — and use it often.

"I use Cetaphil Lotion ALL over my body after showering," Procter & Gamble Section Head Angelica Brown said. The non-greasy formula is super-hydrating, but still lightweight enough to use on your face as well as your body.

Moisturizing is great for dry skin, but exfoliating every so often can help your moisturizer work even better. Skin feels immediately softer after sloughing off dead skin cells and adding lotion or oil to the skin after exfoliating will retain moisture for a supersoft feel.

Tori Moore, scientist at Procter & Gamble, knows the power of this combination. "I really like to focus on hydration and exfoliation because ash is nothing to play with as the season changes!" she said.

Halima Moncrieffe, PhD, assistant professor of pediatrics at Procter & Gamble, also prioritizes exfoliation in the fall, though her product of choice is a facial brush. With exfoliants, she cautions to watch "for any changes that may be caused through overuse like excess oils or outbreaks."

We recommend the Fresh Brown Sugar Scrub because it uses a combination of natural ingredients that exfoliate and moisturize all in one.

Coconut oil can do it all. While many use it in the kitchen, its hydrating, antibacterial, and antifungal properties make it safe and healthy for use on skin too. When the weather cools down, Shameika Wilmington, senior scientist at Procter & Gamble, turns to heavy oils to keep her face moisturized. There are many different coconut oils to choose from, but this one has over 5,500 5-star reviews on Amazon for its high quality and affordable price.

Whether your skin-care concern is acne or wrinkles, retinol promises a fix. The (almost magical) ingredient can help mitigate the signs of aging, acne, hyperpigmentation, and more. Tori Moore, scientist at Procter & Gamble, calls the ingredient "the secret sauce to smooth, younger-looking, even-toned skin."

At the end of the day, what we put inside our bodies is just as important as what we put on the outside. That's why Halima Moncrieffe, PhD, assistant professor of Pediatrics at Procter & Gamble, makes sure to drink lots of water to keep skin feeling fresh.

"Healthy skin comes from the inside out," she said. "I like to keep hydrated with filtered water that I carry around in a metal bottle to reduce chemicals from plastic." We recommend S'well water bottles to anyone looking for a practical stainless steel option in fun colors and designs.

Astral cream has been around for more than 60 years, and its formula has stayed the same the whole time. So it's clear that people find it effective. Halima Moncrieffe, PhD, assistant professor of pediatrics at Procter & Gamble, includes this popular British product in her cold-weather body-care routine to keep skin "glowing and protected against the elements."

Antioxidant vitamin E is said to combat free radicals and help repair skin damage. "I like to return to a heavier vitamin E cream as my main moisturizer and then layer a thin sunscreen product on top of that," Procter & Gamble Research Specialist Nicole Russel said. This soothing cream from Bluemercury's in-house brand, M-61, has a rich texture that'll nourish dry skin.

Depending on how dry your skin gets in the cold weather, it could benefit you to double up on moisturizing agents, like lotions and creams. Lola Kelly Smalls, beauty clinical section head at Procter & Gamble, lives by this method. "I will layer up a petrolatum based product and/or shea butter with lotion to ensure that my skin stays protected and moist," she said. Over 1,500 Amazon shoppers give this product 5 stars. One shopper even said this shea butter "saved [their] dry winter skin in a matter of one day."

Some body washes can strip skin of natural oils, so in the fall opt for one that includes hydrating ingredients to keep moisture in. Tina Allen, beauty clinical trial manager at Procter & Gamble, has been on the Personal Cleansing Clinical Team for most of her 11 years at the company. After being involved in many Olay Body Wash clinical studies over the years, she still goes back to this moisturizing option from the brand. She likes to follow up with Olay Quench Lotion to lock the hydration in.

But Procter & Gamble scientists aren't the only ones who champion the Ultra Moisture Body Wash — more than 1,000 reviewers on Amazon give the product 5 stars.
