You’ve probably heard leather bike—the skincare routine that took social media by storm. But while it started as a viral trend, this dermatologist-approved method has become an enduring staple.
In fact, if you alternate your nightly routine between regenerating and moisturizing, you might already be an expert at skin cycling. We sat down with Dr. Rina Weimann (@drrinaderm) to revisit this tried and true technique and discover why it’s here to stay.
Meet the expert
Rina Weimann (Allawh), MD, FAAD, is a board-certified dermatologist at Schweiger Dermatology Group.

What exactly? it is leather bike?
Let’s start from the beginning. Invented by a dermatologist Dr. Whitney Bowe, leather bike is a skin care routine for four nights which balances exfoliation, retinoid use and repair. It goes like this:
- Night one: peeling
- Night Two: retinoids
- Nights three and four: rest and hydration
The cycle then repeats itself.
This structured rhythm allows the skin barrier to recover between nights with active ingredients. Dr. Weimann explains, “I often recommend alternating retinoids with gentle hydrating moisturizers to minimize skin irritation or redness while maintaining consistency.”
But is it really that innovative? According to Dr. Weimann, it’s just a smart, simplified way to organize your skin care routine: “As a dermatologist, skin recycling isn’t exactly new.” It is, however, a great reminder that sometimes, less is more.

From skincare trend to essential
If you like the idea of glowing results from exfoliants and retinoids, you’re in good company. However, overshooting can they leave the skin barrier vulnerable.
“Embrace product iteration,” says Dr. Weimann. “With all the options out there, it can be easy to take on too much, adding new skincare products every month or even weekly.” But results take time, patience and habit.
By creation built-in recovery nightsa skin rotation routine helps limit irritation and ensures your products work effectively. “While age-defying ingredients like glycolic acid and retinol are great for promoting healthy skin renewal, it can be important to take days to stick to gentle, hydrating ingredients,” adds Dr. Weimann.
A skin rotation routine for beginners
Night one: exfoliator
On the first night, choose a product with exfoliating properties like glycolic acid—a favorite alpha-hydroxy acid (AHA) known for renewal, smoothing and shine benefits.
Apply your exfoliator to clean, dry skin. You can follow with a moisturizer, but skip the retinoids tonight to avoid excessive peeling.

Night two: retinoid
The next night focuses on retinoids. Retinol, retina, tretinoin—these age-defying ingredients work to boost skin renewal, blur fine lines, and improve texture.
After cleansing and smoothing in eye cream, apply your retinoid product to dry skin. Follow with a night moisturizer to soften and balance the skin.
If you are new to retinoids, take it easy on it—your skin may need time to adjust during the retinolation process.

Nights three and four: recovery and hydration
Now it’s time to rest. These two nights are for hydration and barrier recovery—necessary parts of a skin cycling routine.
Dr. Weimann recommends, “Look for ingredients like hyaluronic acid, ceramides, glycerin, vitamin E and niacinamide for an extra boost in skin hydration, improving elasticity and skin barrier strength.”
After cleansing, apply an eye cream, moisturizer and night repair cream to help skin repair overnight. The end result? Irresistibly firm, hydrated and renewed skin.

Give your routine a personal touch
No two routines are exactly alike. “Adjust your skin turnover routine based on your skin type,” advises Dr. Weimann.
“For those who have oilier skinyou may find adding an exfoliator up to three times a week beneficial,” she shares.Sensitive skin can only tolerate a topical scrub once a week.”
But skin type is not the only factor to remember. “Seasonal changes can also affect the skin’s cycling routine,” notes Dr. Weimann. “During his late fall and winterour skin is getting drier and thirstier for that extra boost of hydration.”
If your skin is very sensitive in the colder months, she suggests applying retinoids for a shorter contact period: “Apply your retinoid at dinner time and wash it off before bed.”
Above all, it’s about knowing your skin. Consistency is important, but so is listening to the signals and giving him time to recover.
Can you combine other ingredients with skin cycling?
You can, but keep it simple. Along with retinoids and exfoliants, ingredients like vitamin C, niacinamide, and vitamin E can complement your skin routine. Just remember not to overload – focus on one or two additions at most and apply them on rest nights or as part of you morning routine.

Skin care with staying power
Skin cycling may have started as a trend, but it’s here to stay because it works—giving your skin results and recovery. By alternating between active and rest, you help your skin barrier thrive, not just survive.
As Dr. Weimann reminds us, “When it comes to creating your skin recycling program, talk to a board-certified dermatologist about your skin concerns and find out which ingredients will benefit you the most.”
So whether you’re new to skin cycling or just perfecting your routine, think of it as a mindful moment of care. A little consistency, a little rest, and lots of love for your skin.
