Unlock the Power of Skin Cycling: A Dermatologist’s Guide

As a board-certified dermatologist, one of my all-time favorite skincare practices is skin cycling. It's an efficient, savvy way to maximize the benefits of active ingredients like exfoliants and retinoids while giving your skin time to recover. Whether you’re dealing with aging skin, acne, or sensitivity, skin cycling helps you achieve healthy, glowing skin without the irritation that often comes with the overuse of powerful products.

What is Skin Cycling?

Skin cycling is a 4-day skincare regimen that strategically rotates active ingredients like exfoliants and retinoids, followed by a few recovery days. The goal is to optimize the effectiveness of these treatments while reducing irritation and giving your skin time to repair.

Here’s the typical skin cycling routine:

1. Night 1: Exfoliation. Use a chemical exfoliant like glycolic acid to remove dead skin cells and brighten your complexion.

2. Night 2: Retinoid. Apply a retinoid to boost collagen production, smooth skin texture, and combat signs of aging.

3. Nights 3 & 4: Rest & Repair. Focus on gentle hydration and barrier repair to nourish and protect the skin after active nights.

Why I Love Skin Cycling

Many patients are nervous about starting products like retinoids, and I don’t blame them! They can be irritating, especially in the beginning. This is where skin cycling comes in; it’s a simple, effective way to enjoy powerful ingredients without overwhelming your skin. Skin cycling creates a structure that allows your skin to thrive.

My Favorite Products for Skin Cycling

Here are the products I recommend for each phase of the skin cycling routine:

Night 1: Exfoliation. I recommend products with glycolic or salicylic acids for exfoliation. These ingredients help speed up cell turnover and smooth the skin.

- My pick: Paula's Choice Skin Perfecting 2% BHA Liquid Exfoliant** – A cult favorite that uses salicylic acid to exfoliate and reduce the appearance of pores.

- Alternative: SkinCeuticals Glycolic Renewal Cleanser**– This glycolic acid cleanser gives a deep yet gentle exfoliation.

Night 2: Retinoid. Retinoids are an essential part of skin cycling, as they encourage cell turnover and increase collagen production.

- My pick: Altreno Retinoid Lotion – A gentle prescription-strength retinoid that I often recommend for sensitive skin. This must be prescribed by your dermatologist. Do not start this prescription without speaking to a physician. See more.

- Alternative: Differin Gel** – An over-the-counter retinoid that is effective for both acne and anti-aging.

Nights 3 & 4: Rest & Repair. This is where the magic of skin cycling comes in. After two nights of active treatments, it's important to focus on nourishing your skin with hydrating, barrier-repairing products.

- My pick: Avene Tolerance Cream** – A soothing and hydrating cream that calms sensitive skin and repairs the skin barrier.

- Alternatives: Kiehl's Ultra Facial Cream** – A rich, hydrating moisturizer that provides long-lasting hydration.

Other Ways to Skin Cycle

While the classic skin cycling routine focuses on exfoliants and retinoids, you can adapt it based on your skincare needs. Consider adding products like:

- Vitamin C serums during the day for added brightening.

- Peptides on your rest nights to enhance skin repair.

Skincare Ingredients to Avoid if You Have Sensitive Skin

If your skin tends to be sensitive, it’s essential to avoid certain ingredients during skin cycling:

- Alcohol-based toners– They can strip the skin and cause dryness.

- Fragrance – Common in many skincare products, but can trigger irritation or allergic reactions.

- Harsh physical scrubs – Opt for chemical exfoliants like AHAs or BHAs for a gentler experience.

Skin cycling is an amazing tool to reset and refresh your skin without compromising its barrier. Whether you’re a beginner or experienced with skincare, this method is perfect for achieving radiant skin while reducing irritation. Give it a try, and shop my recommended products to get started!
