When most people think about summer skincare, they worry about oily skin or breakouts. Surprisingly, one of the biggest skin concerns we see during the warmer months is dehydration.
If your skin feels tight, looks dull, or your fine lines suddenly seem more noticeable, dehydration could be the cause.
At YBC London, we often see patients who assume they simply need a richer moisturiser. In reality, dehydrated skin is often caused by a combination of sun exposure, heat, air conditioning and a weakened skin barrier.
The good news is that with the right skincare and professional treatments, dehydrated skin can often be restored to a healthier, more radiant condition.
What Is Dehydrated Skin?
Dehydrated skin is skin that lacks water.
This is different from dry skin, which is a skin type that naturally produces less oil.
Anyone can experience dehydrated skin, including those with oily or combination skin.
When your skin loses too much water, it struggles to function properly, leaving it looking tired, rough and less radiant.
Signs Your Skin Is Dehydrated
You may have dehydrated skin if you notice:
-
Tightness after cleansing
-
Dull or lacklustre skin
-
Fine lines appearing more noticeable
-
Rough texture
-
Increased sensitivity
-
Makeup sitting unevenly
-
Skin that feels oily but still tight
-
Loss of natural glow
Many people mistake dehydration for dryness, leading them to use heavier products that don't address the underlying issue.
Why Does Skin Become Dehydrated During Summer?
Several factors contribute to dehydration during the warmer months.
Increased Sun Exposure
Ultraviolet (UV) rays can weaken the skin barrier, allowing more moisture to escape and making the skin feel tight and dehydrated.
Heat and Sweating
Warmer weather increases water loss through the skin, particularly if you're spending long periods outdoors or exercising.
Air Conditioning
Moving between hot outdoor temperatures and air-conditioned environments can strip moisture from the skin.
Swimming
Chlorine and salt water can disrupt the skin barrier, leaving your skin feeling dry and irritated.
Not Protecting Your Skin
Skipping daily SPF or using harsh skincare products can make dehydration worse by compromising the skin's natural protective barrier.
Drinking More Water Isn't Always Enough
Staying hydrated is important for your overall health, but drinking more water alone won't necessarily solve dehydrated skin.
Healthy skin also relies on:
-
A strong skin barrier
-
Effective moisturising ingredients
-
Daily SPF
-
Gentle skincare products
-
Professional treatments where appropriate
Hydration works best when it's supported both from within and on the surface of the skin.
How to Improve Dehydrated Skin
Simple daily habits can make a significant difference.
Use a Gentle Cleanser
Avoid cleansers that leave your skin feeling tight after washing.
Apply Hyaluronic Acid
Hyaluronic acid attracts water to the skin, helping improve hydration and giving the skin a smoother appearance.
Moisturise Daily
A quality moisturiser helps lock hydration into the skin and supports a healthy skin barrier.
Wear SPF Every Day
Sun protection reduces further damage to the skin barrier and helps prevent moisture loss.
Avoid Over-Exfoliating
Using strong acids or exfoliants too frequently can increase sensitivity and dehydration.
Professional Treatments for Dehydrated Skin
If your skin still feels dehydrated despite following a good skincare routine, professional treatments can help restore hydration more effectively.
Depending on your skin concerns, treatments may include:
Polynucleotide Skin Boosters
Polynucleotides help improve skin quality by stimulating collagen production while supporting hydration and tissue repair.
Skin Boosters
Skin boosters deliver deep hydration to improve skin texture, radiance and elasticity, making them particularly popular during the summer months.
Microneedling
Microneedling encourages natural collagen production while improving the absorption of medical-grade skincare products.
During your consultation, we'll recommend the most appropriate treatment plan based on your skin goals.
