Summer is one of our favourite times of year. Longer days, holidays abroad, evenings spent outdoors and plenty of sunshine can all do wonders for our wellbeing.

Unfortunately, summer can also be one of the toughest seasons for your skin.

At London Professional Aesthetics, we often see an increase in patients booking appointments because their skin suddenly feels dry, looks dull or has become more sensitive. Others notice new pigmentation, fine lines or breakouts that weren’t there just a few weeks earlier.

The surprising part? In many cases, these changes aren’t caused by summer itself—they’re caused by simple skincare mistakes that are easy to avoid.

Here are the seven biggest summer skincare mistakes we see in clinic every year, along with our advice on how to keep your skin healthy, hydrated and protected throughout the season.

1. Thinking SPF Is All You Need

One of the biggest misconceptions we hear is:

“I wear SPF every day, so my skin is protected.”

Sunscreen is incredibly important, but it’s only one part of protecting your skin.

UV exposure still contributes to collagen breakdown, pigmentation and premature ageing, especially if you’re spending extended periods outdoors.

The best protection comes from combining several healthy habits:

✔ Wear a broad-spectrum SPF every day.

✔ Reapply regularly, especially after swimming or sweating.

✔ Wear sunglasses and a wide-brimmed hat.

✔ Seek shade during the hottest part of the day.

✔ Support your skin with antioxidant-rich skincare.

Think of SPF as your first line of defence—not your only one.

2. Only Applying Sunscreen Once

Even people who wear SPF often don’t apply enough or reapply it frequently enough.

If you’re spending the day outdoors, sunscreen should be reapplied approximately every two hours, and again after swimming or heavy perspiration.

It’s also worth remembering that many people forget to protect:

• The ears
• The back of the neck
• The chest
• The backs of the hands
• The tops of the feet

These are often the areas that reveal sun damage first.

3. Over-Exfoliating Because Your Skin Feels Oily

Hot weather and increased perspiration can make skin feel greasy.

Many people respond by using stronger scrubs or exfoliating acids more frequently.

Unfortunately, this can weaken your skin barrier.

When the skin barrier becomes compromised, you may notice:

• Tightness
• Redness
• Increased sensitivity
• Stinging when applying skincare
• Dryness despite using moisturiser

Instead, choose a gentle cleanser and avoid the temptation to “scrub your skin clean.”

Healthy skin is balanced—not stripped.

4. Assuming Drinking More Water Will Hydrate Your Skin

We hear this one all the time.

“I’ve been drinking loads of water—why does my skin still feel dry?”

Hydration isn’t simply about how much water you drink.

Healthy skin also needs a strong skin barrier to retain moisture.

If the barrier is damaged, water escapes more easily from the skin, leaving it feeling dehydrated regardless of how much you drink.

A combination of appropriate skincare, barrier support and, for some patients, professional skin treatments can make a noticeable difference.

5. Waiting Until After Your Holiday to Think About Your Skin

Many patients don’t seek advice until they’re back from holiday and wondering why their skin suddenly looks tired, dehydrated or uneven.

In reality, preparing your skin before summer often produces better results than trying to repair damage afterwards.

Supporting hydration, strengthening the skin barrier and establishing a good skincare routine before increased sun exposure helps your skin cope with the challenges of summer.

This is exactly why we launched our Summer Skin MOT campaign—to encourage prevention rather than correction.

6. Forgetting That Your Neck, Chest and Hands Age Too

When we ask patients where they apply sunscreen, most immediately point to their face.

But the neck, décolletage and hands receive significant sun exposure too.

These areas often develop:

• Fine lines
• Pigmentation
• Loss of elasticity

Making SPF a habit for your face, neck, chest and hands every morning is one of the simplest ways to protect your skin in the long term.

7. Thinking Healthy Skin Means Perfect Skin

Perhaps the biggest misconception of all.

Social media often gives the impression that healthy skin is flawless skin.

It isn’t.

Healthy skin has texture.

It has pores.

It changes with the seasons.

At London Professional Aesthetics, we don’t aim to create skin that looks artificial or over-treated.

Instead, we focus on improving skin quality—helping your skin become healthier, stronger, better hydrated and naturally radiant.

The beautiful patient photographs accompanying this article are a wonderful example of this philosophy. They don’t show dramatic transformation; they show what consistently healthy skin can look like when it’s cared for with the right advice, appropriate treatments and a personalised skincare routine.

So, What Should You Do Instead?

Rather than chasing quick fixes, focus on building healthy habits:

✓ Wear SPF every day.

✓ Reapply it regularly.

✓ Support your skin barrier.

✓ Stay consistent with your skincare routine.

✓ Don’t over-exfoliate.

✓ Protect your collagen.

✓ Seek professional advice if you’re unsure what your skin needs.

Healthy skin isn’t created overnight.

It’s the result of small, consistent decisions that add up over time.

Frequently Asked Questions

Is it safe to have skin treatments during summer?

Many treatments, including LED phototherapy and hydration-focused treatments, can be safely performed during summer when appropriate aftercare advice is followed. Your practitioner will recommend the most suitable options for your skin.

Can I use retinol during summer?

Retinol can often be continued during summer, but it should be used carefully alongside diligent sun protection. Always follow professional advice and avoid excessive sun exposure.

Why does my skin become oilier in hot weather?

Heat increases sebum production and perspiration. This doesn’t necessarily mean your skin needs stronger cleansing or more exfoliation—gentle skincare is usually the better approach.

How often should I reapply sunscreen?

If you’re outdoors, sunscreen should generally be reapplied every two hours and after swimming or excessive sweating. Always follow the manufacturer’s instructions.
