Even though I’m a hardcore skeptic when it comes to gimmicky skincare trends, I still recognize that it can be difficult to stay focused on a simple, no-nonsense routine. New ingredients, new products, and new trends are constantly emerging, and it can be challenging not to get distracted. After all, even the most tried-and-true routine can get a bit dull. But while many skincare trends are easy to ignore, skin cycling may be one trend that’s worth a second look.
Skin cycling initially gained favor on social media in 2022, and has maintained its popularity as one of the more approachable skincare trends in recent years. This is largely because its benefits are twofold: skin cycling strategically maximizes active skincare ingredients while allowing the skin’s moisture barrier essential protection.
But what exactly is skin cycling, and how do you know if it will work for you? Here’s what you need to know.
What Is Skin Cycling?
Skin cycling is a four-night rotational skincare routine that alternates exfoliants, retinoids, and hydrating creams. Popularized by dermatologist Dr. Whitney Bowe, this method is designed to protect the skin barrier, maximize product efficacy, and prevent irritation from layering too many harsh actives. The goal of skin cycling is to maximize the effect of regenerative ingredients while giving skin time to recover in between.
Potential Benefits of Skin Cycling
Although skin cycling has not been clinically studied, the theoretical benefits include:
Reduced Sensitivity and Irritation: Spacing out the use of active ingredients can help reduce redness, peeling, and burning. Limiting exfoliants and retinoids to once every four days prevents overuse and potential damage to the skin barrier.
More Focus on Rest and Repair: Allocating two out of every four nights for skin rest and recovery can repair damage to the skin barrier and enhance its resilience.
Better Retinoid Absorption: Cleansing and exfoliation on night one helps remove dead skin cells, allowing better penetration by retinoids on night two.
Minimizes Product Use and Encourages Consistency: Having a well-defined routine with a limited selection of products results in more consistent usage.
Products You’ll Need
If you want to try skin cycling, you’ll need four essential skincare products. Whenever possible, opt for fragrance-free, hypoallergenic, and noncomedogenic options. If you have sensitive, acne-prone, or melanin-rich skin, it’s advisable to consult a dermatologist before trying skin cycling. They can provide personalized recommendations tailored to your specific needs and skin type.
Gentle Facial Cleanser: Look for a non-abrasive, alcohol-free cleanser.
AHA or BHA Chemical Exfoliant: Alpha hydroxy acids (AHAs) are mild exfoliants that can help smooth and soften the skin, as well as reduce the appearance of fine lines and wrinkles. Beta hydroxy acids (BHAs) offer gentle exfoliating benefits that can be useful for acne-prone skin or rough skin that needs smoothing.
OTC Retinol or Retinoid: Retinols typically refer to over-the-counter products that are less concentrated, while retinoids are usually more powerful, prescription formulas.
Hydrating Moisturizer: Moisturizers draw moisture into the top layers of the skin and help repair breaks in the skin barrier.
Broad-Spectrum Sunscreen: Apply sunscreen every morning to protect your skin throughout the day.
A Typical 4-Night Schedule
To illustrate how skin cycling works in practice, here’s an example of a typical nighttime routine:
Night 1 - Exfoliation: Wash your face with a gentle cleanser and pat dry. Apply a leave-on chemical exfoliant containing alpha-hydroxy acids (AHAs), such as glycolic acid, or beta-hydroxy acids (BHAs), such as salicylic acid. Finish with a basic, non-active moisturizer.
Night 2 - Retinoid: To minimize irritation, cleanse and thoroughly dry your skin. Then, apply a pea-sized amount of retinol or a prescription-strength retinoid. Follow up with a moisturizer immediately to create a soothing barrier.
Nights 3 and 4 - Recovery: Gently cleanse your skin. Avoid all active serums, acids, and retinoids. Instead, apply a hydrating moisturizer with barrier-repairing ingredients like hyaluronic acid, ceramides, or squalane. On night 5, begin the cycle again.
While not an official part of the skin cycling routine, dermatologists generally advise cleansing your face in the mornings and applying a broad-spectrum sunscreen to shield your skin from the sun’s harmful rays. This is particularly crucial because the active ingredients in chemical exfoliants, retinols, and retinoids increase your skin’s sensitivity to sun damage.
Potential Drawbacks of Skin Cycling
The primary drawback of skin cycling is that it reduces the frequency of active ingredients like retinoids, which can hinder or diminish your overall results. While the structured four-night rotation helps prevent irritation, it’s not a one-size-fits-all solution and may not be effective enough to address specific skin concerns. For instance, retinoids work best when used consistently. Using retinol only once every four nights delays your skin’s ability to build up a tolerance. For mature or more resilient skin, a single night of retinol per cycle may not be frequent enough to effectively stimulate collagen or noticeably reduce deep wrinkles.
Similarly, acne-prone skin often requires daily or near-daily applications of salicylic acid or prescription retinoids to keep pores clear. The standard two recovery nights can lead to breakouts. Likewise, stubborn dark spots and sun damage generally require consistent, daily interventions with brightening actives rather than intermittent treatment.
In essence, skin cycling overlooks the fact that individual skincare needs vary. The rigid four-night cycle lacks the flexibility required to address specific skin conditions. While skin cycling may be suitable for beginners, it might hinder the progress of individuals with more skincare experience, those with specific skin conditions, and those with mature and resilient skin.
Final Thoughts
While skin cycling is a practical and approachable skincare trend, it may not be suitable for everyone. The numerous variables involved make it challenging to assert that a single skincare routine can cater to the diverse needs of different skin types. While it may be a good starting point for those new to skincare, others may find it not effective enough to achieve their skincare goals. Similarly, those with sensitive skin and certain skin conditions may find that certain ingredients (such as retinoids and chemical exfoliants) are too harsh. In the end, it’s always best to exercise caution and consult with a dermatologist or esthetician to develop the most suitable plan for your needs.
