Incorporating retinol into your skincare routine can be intimidating, especially with its reputation for causing irritation. Despite its benefits, such as reducing fine lines, treating acne, and promoting firm, plump skin, retinol can be harsh, particularly for those with sensitive skin. 

Thankfully, a trend on TikTok, known as the "retinol sandwich method," is gaining popularity for its promise to mitigate these issues.

What is retinol?

Retinol is a derivative of vitamin A, celebrated for its ability to accelerate cell turnover and boost collagen production, according to Cleveland Clinic. This powerhouse ingredient is often used to address signs of aging, improve skin texture, and treat acne. 

However, its potency can lead to side effects like dryness, redness, and flakiness, particularly when not introduced to the skin properly.

The retinol sandwich method

The retinol sandwich method involves layering retinol between two applications of moisturizer, hence the name. This technique is designed to buffer the skin from the potential harshness of retinol, reducing the likelihood of irritation. 

Here's a step-by-step guide on how to do it:

Step 1: Cleanse your skin

Begin with a gentle cleanser that effectively removes impurities without stripping your skin of its natural oils. This step ensures your skin is clean and ready to absorb the subsequent products.

Step 2: Apply moisturizer

While your skin is still slightly damp from cleansing, apply a thin layer of moisturizer. This initial layer of hydration helps prepare your skin and creates a barrier that can reduce the intensity of retinol absorption.

Step 3: Apply retinol

Once the first layer of moisturizer is fully absorbed, apply your retinol product. Be sure to follow the instructions specific to your retinol, avoiding sensitive areas like around the eyes and corners of the mouth. Allow the retinol to absorb completely before proceeding.

Step 4: Finish with another layer of moisturizer

After the retinol has been absorbed, apply a second, more generous layer of moisturizer. This final layer helps lock in hydration and further buffer your skin against potential irritation from the retinol.

Why do the retinol sandwich method?

The primary benefit of this method is its ability to minimize irritation associated with retinol use. By sandwiching the retinol between two layers of moisturizer, the skin is better hydrated, which can help mitigate dryness, redness, and flakiness. 

The initial layer of moisturizer allows the skin to absorb moisture first, leaving less room for retinol molecules and reducing adverse side effects, dermatological nurse Natalie Aguilar said, as reported by Pop Sugar.

Frequency and precautions

Begin by using the retinol sandwich method once or twice a week, preferably at night, and gradually increase the frequency as your skin adjusts, Origins recommended. 

Remember to consult your dermatologist for more personalized advice, and always follow the specific directions on your retinol product.
