Don't Make This Summer Skincare Mistake (It's Not What You Think)

Like many myths, this one began with a small amount of truth.

Many traditional retinoids and vitamin C formulations can cause irritation, particularly in people who are new to them or using stronger concentrations. If someone applies these products and then spends hours in direct sunlight without proper protection, redness and irritation can become more noticeable.

Over time, a reasonable warning about protecting your skin evolved into a much broader message: "Stop your active ingredients during summer."

The problem is that skin aging doesn't work that way.

• Collagen breakdown doesn't stop during summer.
• Pigmentation doesn't stop during summer.
• UV damage certainly doesn't stop during summer.

So why would the ingredients and treatments designed to help combat those changes suddenly become unnecessary?

One of the biggest mistakes I see people make is focusing on the wrong problem.

• They're worried about retinol.
• They're worried about vitamin C.
• They're worried about peels and lasers.

Meanwhile, they're overlooking the biggest contributor to skin aging: ultraviolet radiation.

The goal shouldn't be to stop your anti-aging routine.

The goal should be to improve your sun-protective habits.

These are the questions I hear from patients every summer, and they all come back to the same principle: your skin does not need less support during summer. It needs smarter protection.

Once we understand that the real concern is sun exposure, not the ingredients or treatments themselves, the conversation becomes much clearer.

Absolutely.

This is probably the most common summer skincare question I receive.

Retinol and other retinoids help stimulate cellular turnover and support long-term remodeling processes that improve fine lines, wrinkles, texture, pigmentation, and overall skin quality.

Those benefits accumulate gradually over time.

When people stop retinol every summer and restart every fall, they repeatedly interrupt that process. Many also find themselves re-entering the adjustment phase each year.

What matters isn't avoiding retinol. What matters is using retinol responsibly.

That means:

• Wearing broad-spectrum sunscreen daily
  
• Wearing hats and protective clothing outdoors
  
• Seeking shade whenever possible
  
• Choosing formulations that are well tolerated
  
• Avoiding excessive, unprotected sun exposure
  

If your retinol routinely causes significant irritation despite good sun-protective habits, it may be time to reconsider the formulation—not abandon active ingredients altogether.

Not only can you use vitamin C during summer, it's one of my favorite ingredients to use during periods of higher sun exposure.

Vitamin C is a powerful antioxidant that helps neutralize free radicals generated by UV exposure. Think of it as another layer of defense that works alongside sunscreen.

Sunscreen helps block UV radiation. Vitamin C helps address some of the oxidative stress that still occurs despite good sun protection.

The misconception likely comes from the fact that vitamin C itself can be unstable when exposed to light and air.

That doesn't mean it shouldn't be used during summer. It simply means formulation quality matters.

Morning vitamin C followed by sunscreen remains one of my favorite combinations for long-term skin health.

Yes.

I've heard this myth for decades.

If chemical peels couldn't be performed during summer, they would barely exist in Southern California.

The reality is that chemical peels can be safely performed throughout the year. The determining factor isn't the season. It's patient behavior.

If you are undergoing peels in the summer, you need to:

• Minimize unnecessary sun exposure
  
• Follow post-treatment instructions
  
• Allow the skin to heal properly
  
• Use diligent sun protection throughout recovery
  

The issue isn't the time of year. The issue is whether you're protecting the healing skin.

The same principle applies to laser treatments.

Many patients are surprised when I tell them that laser resurfacing can be performed year-round.

The concern has never been the season itself. The concern is excessive sun exposure before and after treatment.

Patients should avoid tanning, minimize unnecessary UV exposure, and allow their skin to heal appropriately after treatment.

Once healing has occurred, sunscreen, hats, sunglasses, shade, and protective clothing become critical.

The calendar doesn't determine success.

Patient behavior does.

Before switching to the KaramMD products, my wife spent roughly 15 years using full-strength retinoids and vitamin C. She also spends far more time outdoors than most people.

For years she regularly spent multiple hours each day walking, hiking, exercising outdoors, attending our sons' sporting events, and enjoying an active Southern California lifestyle.

One of the most important lessons I've learned throughout my career is that skin responds to consistency.

• The same principle applies to exercise.
• The same principle applies to nutrition.
• The same principle applies to healthy aging.

Results are rarely created by occasional bursts of effort. They're created by steady, daily habits repeated over years.

That's why I find the advice to stop active ingredients every summer so counterproductive.

You're interrupting the very process that creates long-term improvement.

Instead of stopping your active ingredients during summer, focus on the things that actually matter:

• Use broad-spectrum sunscreen every day
  
• Wear hats and sunglasses outdoors
  
• Seek shade whenever possible
  
• Consider sun-protective clothing
  
• Stay consistent with your active ingredients
  
• Adjust formulations if irritation becomes an issue
  
• Work with your physician if you have questions about specific products or treatments
  

Summer isn't the enemy. Unprotected sun exposure is.

The biggest summer skincare myth isn't that retinol, vitamin C, chemical peels, or lasers are unsafe during summer.

The biggest myth is believing that these treatments are the problem.

They're not.

The real issue has always been unprotected sun exposure.

After more than 30 years helping patients care for their skin in Southern California, my advice remains simple: protect your skin from the sun, stay consistent with the ingredients that work, and remember that aging doesn't take the summer off.

Why do people think retinol shouldn't be used during summer?
This myth likely developed because retinoids can cause irritation, especially when someone is new to them or using a stronger formulation. Over time, a reasonable warning about sun protection evolved into the much broader belief that retinol should be stopped altogether during summer.

Does retinol make your skin more sensitive to the sun?
Retinol can increase irritation if skin is exposed to excessive sunlight without protection. This is why sunscreen and sun-protective habits are important. Most people can continue using retinol year-round.

Will I lose progress if I stop retinol for the summer?
You won't suddenly lose all of your results, but you may interrupt the long-term remodeling process that retinoids help support. More importantly, many people find themselves restarting the adjustment period every fall.

Should I stop vitamin C during summer?
No. Vitamin C is an antioxidant that can help protect against oxidative stress caused by UV exposure and is often especially useful during summer months.

Does vitamin C make your skin more sensitive to the sun?
No. Vitamin C does not make your skin more vulnerable to UV damage. In fact, it helps support your skin's defenses against environmental stress.

Should I stop active ingredients before going on vacation?
No. Most people can continue using their active ingredients while traveling if they maintain good sun-protective habits.

Are chemical peels safe in summer?
Many chemical peels can be safely performed year-round when patients follow proper recovery and sun-protection instructions.

Can laser resurfacing be done during summer?
Yes. The key is minimizing excessive sun exposure before treatment and protecting healing skin afterward.

What is the biggest summer skincare mistake people make?
In my experience, it's focusing on the wrong problem. People worry about active ingredients while overlooking the cumulative effects of unprotected sun exposure.

Does aging slow down during summer?
Unfortunately, no. Collagen breakdown, pigmentation, oxidative stress, and other aging processes continue year-round.
