There’s a new skin care trend making waves through TikTok, but it’s not a product. It’s a technique called skin cycling.
This viral trend is credited to dermatologist Dr. Whitney Bowe, who suggests using a four-day cycle, changing the skin care products you use each night.
“This is new on social media and in the news, but many dermatologists have been advising this for years,” explained Dr. Loretta Pratt, a board-certified dermatologist with Advanced Dermatology, P.C. “I have been practicing skin cycling with my own skin care products and routine for over 20 years.”
Part of the appeal of skin cycling is that you use certain products on different days instead of layering them all at once, which could lead to irritation.
Bowe’s skin cycling routine can easily be followed at home. Keep your morning routine the same: cleansing, adding any extra serums you may want, and, of course, applying sunscreen.
“For the daytime routine, the final application should always be a sunscreen/SPF product for your specific skin type,” Pratt said.
Nighttime is when skin cycling really starts.
“The routine is based on a four-night schedule: exfoliation (acids) night, retinoid night, recovery night, and another recovery night,” explained Alexandra Ward, a licensed esthetician at Reform Aesthetics in Encino, California. “The idea is that the skin will receive both a retinoid and exfoliant while also preventing any irritation.”
Day 1: Exfoliation Night
“The first night of treatment should include a chemical exfoliant, such as a gentle at-home peel, to provide even exfoliation,” said Dr. Jaimie DeRosa, double board-certified facial plastic surgeon and founder of DeRosa Center Facial Plastic Surgery & Med Spa in Boston and Palm Beach. “An exfoliant should always be applied after gentle cleanser and always be followed by a moisturizer.”
There are multiple benefits to starting off the cycle with an exfoliation night. Not only will it clear away dead skin, making your skin smoother, but it preps your skin to absorb products better on the next day of the cycle.
For exfoliation night, Dr. Gary Motykie, a board-certified plastic surgeon in Beverly Hills, recommended using SkinCeuticals Glycolic Renewal Gel Cleanser. While it’s a gentle cleanser, the glycolic and phytic acids help exfoliate and dissolve dead skin.

Day 2: Retinol Or Retinoid Night
“Just like the first night, start night two with applying gentle cleanser to prep the skin for retinol,” DeRosa said. “Use only a small amount, as retinol is a skin irritant and, if you are just starting using it or have sensitive skin, be especially cautious not to overdo it.”
Why have a retinol night in the skin cycle? Retinol is essentially a miracle product. It increases skin cell production and helps stimulate collagen production, which in turn leads to fewer wrinkles, fading dark spots and improved skin texture.
There are numerous retinol products on the market. If you don’t currently have one in your medicine cabinet, Ward recommended Skinbetter Alpharet Overnight Cream.
If you’re a retinol newbie, consider starting with something gentle, like Fleur and Bee ‘A’ Game Serum, which has a lower percentage of retinol and naturally soothing ingredients like jojoba oil, aloe vera, and green tea.

Day 3 And Day 4: Recovery Nights
After the exfoliation and retinol nights, the next two days will focus on letting your skin rest. On these nights, all you have to do is cleanse and use moisturizer.
“I recommend using a simple moisturizer and making sure it doesn’t have any hidden active [ingredients], vitamin A, or retinol in it,” Ward said. “I love Epionce Medical Barrier Cream and Dieux Instant Angel Moisturizer as both contain fatty acids to focus on restoring the skin’s barrier.”
There is some wiggle room in these nights if you feel this isn’t enough moisture for your skin type.
“If there is need for extra hydration (if your skin feels dry) then consider adding a hyaluronic acid serum after cleansing and before adding the moisturizer,” DeRosa said. “If you want to go even further and keep the moisturizer locked in for better hydration, use skin oil on top of it to keep the moisture in.”
If you’re someone who wants extra moisturizer, DeRosa recommended, “Alphascience HA Booster Serum is fantastic.”
“The 0.5% pure hyaluronic acids include both low and high molecular weights, which means that some of the [hyaluronic acid] goes deeper into the skin’s epidermis, while the rest stays closer to the surface of the skin, making the skin more hydrated for the short and long term,” she said.
After your second recovery night, it’s time to restart the cycle.
Special Considerations When Skin Cycling
If you’re someone who doesn’t have much of a skin care routine, be careful not to jump in too quickly.
“If you’re going to skin cycle, start low and go slow. The technique allows you to gradually introduce stronger products,” Motykie said. This technique might not be for everyone and it’s helpful to first consult with an expert, he explained.
“If you have sensitive or reactive skin, you don’t want to introduce a super active product. A skin expert can help you select the products that will be right for you,” Motykie added. “Also, if you’re on Accutane or any other acne medication, you want to stick to super gentle products, skin cycling wouldn’t be the right routine for you.”
As beneficial as skin cycling can be (just look up the awesome results on TikTok), the most important part of any skin care routine happens in the morning: applying sunscreen. You can cycle with the best products, but if you’re not using sun protection, the damage will far outweigh the benefits of your new nightly routine.

But those with dry or curly hair needing moisture — yes yes yes! Keep the box for directions because you can’t read the ones on the bottle if you don’t understand the language.” — Kandyce D.
Cerave hdrating cleanser, a must-have for anyone who deals with acne, dry, or sensitive skin
Promising review: “I got this after seeing a recommendation on TikTok. It’s been a lifesaver for me. I have dry, red, sensitive, acne-prone skin. Most cleansers strip my skin, but not this one. It’s been helping keep my skin clear while not drying it for a few months now. If you have dry skin this is a must!” — L Ashburne

Promising review: “OK. This 👏 thing 👏 is 👏 amazing 👏. I have two sisters that are professional cosmetologists and well that talent surpassed me COMPLETELY. I have straight, stubborn hair. I’ve never been able to get it to do anything. I’ve never been good at using a curling iron, wand, leave-in curlers or had any luck with the “wavy hair hacks.” So I did my research when I saw this thing on TikTok, of all places, and WOW, I’m super impressed. I’ve used it twice so far and truly LOVE IT! It’s very easy to use.” — LinLo09

An exfoliating scrub mitt you can use a couple of times a month to remove all the excess dead skin and particles on your skin
Promising review: “I have very thin and light body hair, so any form of removal (shaving, waxing, etc) usually leaves me with a lot of ingrown hairs. I’ve tried body scrubs and washcloths and neither really do a great job. I saw this product recommended by a dermatologist on TikTok and thought I’d try it — it’s amazing! I also have very sensitive skin, and this mitt doesn’t leave my skin irritated at all. However, absolutely do not use this mitt on your face, neck, or other sensitive areas, it would be way too harsh. I like to use this mitt first when I get in the shower, then use a body wash (a gentle chemical exfoliant) and follow up with body lotion for dry and sensitive skin. This whole routine is fragrance-free and leaves my skin feeling very soft and moisturized.” — Kat

It’s available in 18 shades.
Promising review: “I personally like this product. Throughout high school (I recently graduated in June), I never knew how to do makeup. But then I heard this product was the absolute best on TikTok. And trust me, they were not lying. It has really good coverage and hides my ‘raccoon eyes.’ And the beat part is that a little bit goes a long way. So if you’re starting out or want to try something new I definitely recommend to try this out .Liela Lee

Maybelline’s Lash Sensational Sky High mascara because the sky’s the limit when it comes to your lashes
Promising review: “I bought this mascara after seeing it go viral on TikTok. This stuff is incredible. I’ve been using this mascara for two months, and it’s still performing very well. I admit that I am not a fan of the packaging (it feels clunky, cheap, and plasticy), but it’s the inside that counts, right? The formula builds well. The brush is the perfect length to grip and coat all of my lashes. It lengthens my short eyelashes after just one coat! I tested this against my more expensive mascaras, and it performed better than most!” — Gizelle Cade

Or an edge control gel reviewers swear stays in place all day and doesn’t flake
Promising review: “So, I first found out about this product in my Cosmo school I attend and fell in love. It stays on just right for a long time, just as advertised! I had bought a different edge tamer and was disappointed, but this one exceeds my expectations, which is why I also purchased the largest tub size! Maria
L’Oréal Paris Infallible Fresh Wear powder foundation because it’s bound to be your new favorite foundation as soon as you try it
Promising review: “I have purchased this three times in the color Sienna, and it is perfect! It’s totally worth all the hype on TikTok. This is a very emollient powder that sticks to the skin. I prep with sunscreen then use this. The fragrance dissipates quickly. I noticed the actual powder is bouncy to the touch. I have not used the pelican or sponge it comes with. I like to use a powder brush. It gives me full coverage, and I look flawless all day. I also don’t need to blot. And I am very oily. I will certainly continue to repurchase. This is the best powder I have tried since Mac Studio Fix.” — Maria Webba

A heatless curling rod headband perfect for anyone who wants to cut down on the amount of heat they use on their hair
Promising review: “Before purchasing, I’d seen a lot of reviews and tutorials on TikTok showing the results. My hair is thick, coarse, and naturally wavy, so I figured this might be a good alternative to rollers that are time-consuming to put in, difficult to sleep in, and ultimately not worth it. And MAN was I right to be hopeful. Wrap pieces of damp hair around it before bed, the tighter the wrap, the tighter the curl. Easy to sleep in since there’s nothing on the back of your head, and my curls are BOUNCY the next morning. My only complaint is that it doesn’t help give any top-volume, but nothing some teasing can’t fix. 10/10. I’ll never go back to a curling iron.” — Mariah
L’Oreal Paris Elvive 8 Second Wonder Water to help reverse damage to your hair in eight seconds
Promising Reviews: “Yes, I actually saw this product reviewed on TikTok and had to try it. It is amazing stuff, OMGOSH!!! I have already purchased my second bottle. I have a lot of hair, and it gets tangled easily this stuff made it soft and manageable after the first use. PLEASE be careful not to get it on your scalp it does start to feel warm almost like when you have had your hair color on too long, I just use it more towards the ends. Overall great stuff.” — Jennifer Borchers
A bottle of NYX setting spray you can spritz on after doing your makeup in the morning and not have to worry about applying again
Promising review: “I had seen this on TikTok and thought it was a waste of money, until I tried it, and it works. It locks in your makeup. You just have to make sure your makeup is perfect and then spray your face.” — Mary
A Marshmallow Whip Maker so you can whip up your favorite face cleanser and turn it into a cup of frothy foam
Promising review: “I bought this product after doing a bunch of reviews after seeing it all over my TikTok feed. This device takes your cleanser and turns it into a foamy product. Why would you want your cleanser to be foam? First, you will make your cleanser last WAY longer. You add a little bit of cleanser and water, then pump it a few times. Instantly it’s foam. You will be using less product, which means you will save money. Another reason is that the product became concentrated and when you put on your face you get the whole product all over your entire face. Foam cleansers are preferred when cleansing because it’s more thorough when washing. It gets the whole surface area. Third, it’s fun! You pump and you instantly have foam. I made a video on TikTok and it went viral! This product is so cute and fun plus it will help stretch your cleanser.” — Aimee Rouseau
A Revlon One-Stop Hair Dryer & Volumizer that’s going viral for a reason: It cuts drying time in half *and* helps you easily create a salon-worthy blowout at home.
Promising review: “THIS. IS. EVERYTHING. TikTok made me buy it. I actually have 3b wavy hair that’s very thick. I gave up blow drying a long time ago… never worked for me with all this hair. Now, I have myself a near salon quality blow out with nothing but this tool and CLEAN HAIR! I didn’t even towel dry, just air dried for 15 minutes. Life changing. Even if it breaks, I will buy again. It’s so nice to have that blown out look for style and convenience, but it’s perfectly primed for straightening (I’m sure I can get BONE STRAIGHT). I just can’t say enough good things about this god send for THICK HAIR! And it’s easy to maneuver and manage while using it. And again, I put zero product to achieve this look! So smooth!!” — Dominique Morrow
