Skin Changes in Summer: When to Get Them Checked

Summer often brings a welcome change in routine — more time outdoors, more sun exposure, and more attention to skin that's been covered up for much of the year. But it's also the season when people are most likely to notice new or changing marks on their skin.

At Chelmsford Private GPs, we often see patients who are unsure whether a mole, freckle, or patch of skin is something to be concerned about. In many cases, changes are harmless — but sometimes they can be an important early warning sign that shouldn't be ignored.

Why skin changes are more noticeable in summer

Increased sun exposure can make existing moles darker or more prominent, and tanning can highlight areas of pigmentation that weren't previously obvious. People are also more likely to see their skin in different lighting and angles during warmer months, especially on areas like the back, shoulders, and legs.

This makes summer a key time to stay aware of any changes — both new and existing.

What to look out for

Most skin spots are benign, but it's important to be aware of changes using the ABCDE guide:

• A – Asymmetry: one half doesn't match the other
• B – Border: irregular, blurred, or ragged edges
• C – Colour: uneven colour or multiple shades
• D – Diameter: larger than 6mm or increasing in size
• E – Evolving: any change in size, shape, colour, or symptoms over time

Other signs to watch for include itching, bleeding, crusting, or a sore that doesn't heal.

Not all changes are serious — but they should be checked

It's important to remember that many skin changes are completely harmless, including sun-induced pigmentation, seborrhoeic keratoses, or simple changes in existing moles over time.

However, the key factor is change. Any spot that is new, evolving, or unusual for you is worth assessing properly rather than monitoring indefinitely at home.

When to seek medical advice

You should consider booking an appointment if you notice:

• A new mole appearing in adulthood
• An existing mole changing in appearance
• A lesion that bleeds, crusts, or doesn't heal
• Any spot that looks different from your others ("ugly duckling" sign)

Early assessment is always preferable, as it allows for reassurance or timely referral if needed.
