Can You Use Retinol in the Summer?
The Short Answer: Yes, You Can.
One of the most common skin care questions I hear every summer is:
"Should I stop using retinol when it's sunny outside?"
The answer is simple: No.
This is one of the biggest skin care myths I encounter, and unfortunately, it causes many people to pause one of the most effective ingredients in their routine just when consistency matters most.
Retinol remains one of my favorite ingredients for improving the appearance of fine lines, uneven skin tone, and rough skin texture. Summer doesn't change that.
What does change is how you should use it.
Why People Think Retinol Isn't Safe in the Summer
This misconception comes from the fact that retinol can make your skin more sensitive to the sun, particularly when you're first introducing it into your routine.
That doesn't mean retinol is unsafe during the summer—it simply means your skin needs a little extra protection.
Think of it this way: retinol and sunscreen aren't opposites. They actually work best as a team, and the good news is that you don't need to stop using retinol during the summer. You simply need to pair it with daily broad-spectrum sunscreen and smart sun protection.
My Three Rules for Using Retinol During the Summer
If you want healthier-looking skin year-round, these are the three recommendations I give my patients.
1. Apply Retinol at Night
Retinol is designed to be part of your evening skin care routine.
While you sleep, your skin naturally shifts into repair mode, making nighttime the ideal time to apply products that support skin renewal.
Applying retinol before bed also avoids unnecessary sun exposure immediately after application.
2. Start Slowly If You're New to Retinol
If you've never used retinol before, don't feel like you need to jump into nightly use.
I typically recommend starting with two or three evenings per week, then gradually increasing the frequency as your skin becomes more comfortable with the ingredient.
Introducing retinol slowly can help minimize temporary dryness or irritation while allowing your skin to build tolerance over time - for example, within a moisturizer or eye cream.
Remember: skin care is a marathon, not a sprint.
3. Wear Sunscreen Every Morning
If there's one habit I never skip, it's sunscreen.
Daily broad-spectrum SPF is important throughout the year, but it becomes especially important when you're using retinol.
Sunscreen not only helps protect your skin from UV damage, but it also helps preserve the progress you're making with your skin care routine.
No skin care product can outwork unprotected sun exposure.
Choosing the Right Retinol Product
One of the biggest mistakes I see isn't using retinol in the summer, it's using a product that's simply too strong.
Many people assume stronger is better, but that's not always the case.
A gentle, well-formulated retinol moisturizer can be an excellent place to start, especially if you're new to retinol or have sensitive skin.
My YOUN Beauty Retinol Moisturizer was formulated to help improve the appearance of fine lines, uneven texture, and dull-looking skin while remaining gentle enough for regular use.
And skin care doesn't have to stop at your jawline.
If you'd like to extend your routine beyond your face, YOUN Beauty Retinol Body Crème is designed to help improve the appearance of skin on the neck, chest, arms, and other areas that often show visible signs of aging.
Should You Use Retinol in the Summer? The Bottom Line
You don't need to stop using retinol just because summer arrives.
Instead, focus on using it consistently and correctly:
-
Apply it in the evening.
-
Introduce it gradually if you're new.
-
Wear a broad-spectrum sunscreen every day.
In my experience, consistency is far more important than intensity. Healthy-looking skin isn't built overnight—it's the result of small, smart habits practiced over time.
Frequently Asked Questions
Can I use retinol every night during the summer?
Yes. You can safely use retinol during the summer as long as you apply it at night and wear broad-spectrum sunscreen every morning. There's no need to stop using retinol simply because it's sunny outside.
Does retinol make your skin thinner?
No. This is another common myth. While retinol can temporarily cause dryness or peeling as your skin adjusts, it does not thin the skin. In fact, it helps support normal skin renewal over time.
Can I use retinol if I spend a lot of time outdoors?
Yes—but daily sunscreen becomes even more important. Wearing protective clothing, seeking shade when possible, and reapplying SPF throughout the day can help protect your skin while using retinol.
Should I stop retinol before going on vacation?
Not necessarily. If you're planning extended sun exposure or your skin tends to become irritated while traveling, you may choose to simplify your routine temporarily. Otherwise, many people can continue using retinol as long as they're diligent about sun protection.
What should I apply after retinol?
A gentle moisturizer can help support your skin barrier and minimize dryness. Many retinol moisturizers combine these steps into one product, making your nighttime routine simple and effective.
Can beginners use retinol?
Absolutely. I simply recommend starting slowly. Using retinol two or three nights per week allows your skin to adapt while reducing the likelihood of irritation.
What's the biggest mistake people make with retinol?
The biggest mistake isn't using retinol during the summer, it's using it inconsistently or forgetting daily sunscreen. Consistency, patience, and sun protection are what lead to the best long-term results.
If you're looking for healthier, smoother, more youthful-looking skin, there's no reason to put your retinol away for the summer. Simply use it at night, protect your skin with sunscreen every morning, and stay consistent. Your future skin will thank you.
