The main reasons to avoid sun exposure after using retinol are that retinol is broken down by sunlight, and it also increases your skin's sensitivity to the sun.
The Sun and Retinol: A Bad Mix
Here's why you should limit sun exposure when using retinol products:
- Retinol degrades in sunlight: Ultraviolet (UV) light from the sun breaks down retinol, making it less effective. 5 This means the product won't work as well if you apply it and then go out in the sun.
- Increased sun sensitivity: Retinol can make your skin more sensitive to the sun's harmful rays. 5 This increased sensitivity significantly raises your risk of sunburn, sun damage, and long-term issues like premature aging and skin cancer.
How to Protect Your Skin While Using Retinol
To safely incorporate retinol into your skincare routine, follow these precautions:
-
Nighttime application: Apply retinol products at night. This minimizes exposure to sunlight and allows the product to work while you sleep.
-
Sunscreen is a must: Use a broad-spectrum sunscreen with an SPF of 30 or higher every morning, even on cloudy days. Sunscreen is crucial for protecting your retinol-sensitized skin.
-
Protective clothing: Wear protective clothing, such as hats and long sleeves, when exposed to the sun, especially during peak hours (10 AM to 4 PM).
-
Start slow: Introduce retinol gradually into your routine (e.g., once or twice a week) to allow your skin to adjust and minimize irritation.
-
Avoid sunlamps and tanning beds: These artificial sources of UV radiation are just as harmful as the sun and should be avoided altogether while using retinol.
By understanding the relationship between retinol and sun exposure, you can take the necessary precautions to safeguard your skin.
