Your skin can reveal a great deal about your overall health. While occasional dryness, minor irritation or a temporary blemish may not be cause for concern, certain changes should never be dismissed. A new spot, changing mole, persistent rash or unexplained skin lesion may require professional assessment.
Understanding which skin changes deserve attention can help you seek appropriate care at the right time. Dr Shaun Segal, a highly regarded dermatologist based in Kingswood, New South Wales, has extensive experience diagnosing and managing a wide variety of dermatological conditions. His patient-centred approach highlights the importance of paying attention to changes in your skin and seeking professional advice when something does not seem right.
Here are five skin changes you should never ignore.
Moles are common, and most are harmless. However, changes in an existing mole should be taken seriously. Pay attention if a mole changes in size, shape, colour or texture.
One useful way to monitor suspicious changes is to consider the ABCDE characteristics:
Not every changing mole indicates a serious condition, but changes should be assessed by an appropriately qualified medical professional.
A new spot on the skin may have many possible causes. It could be a harmless pigmentation change, an age-related mark or another benign condition. However, a new or unusual lesion that looks different from the surrounding skin deserves attention.
This is particularly important if the spot continues to grow, changes colour, develops an irregular shape or does not appear to heal normally.
Australia has significant ultraviolet exposure, making awareness of skin changes particularly important. Regularly checking your skin can help you notice new or changing areas that may need professional assessment.
Dr. Shaun Segal’s extensive dermatological experience allows him to assess a wide range of skin concerns and determine when further evaluation may be appropriate.
A minor cut or skin irritation would generally be expected to improve with time. If a sore, scab, ulcer or lesion remains for an unusually long period, repeatedly heals and returns, or changes in appearance, it should not simply be ignored.
Persistent skin lesions can have different causes, ranging from inflammatory conditions to infections and other medical problems. Attempting to treat a persistent lesion repeatedly with over-the-counter products without understanding its cause may delay appropriate care.
A dermatologist can examine the affected area and determine whether additional investigation or treatment is required.
Occasional itching or redness may occur because of dryness, environmental exposure or irritation. However, persistent symptoms can sometimes indicate an underlying dermatological condition.
Eczema, dermatitis, psoriasis, infections and other skin conditions can cause ongoing itching, redness, scaling or discomfort. If symptoms continue despite basic skincare measures, worsen over time or interfere with everyday activities, professional advice can be valuable.
Rather than continually switching skincare products, consider having persistent symptoms properly assessed. Identifying the underlying cause can help guide a more suitable approach to management.
Changes in skin texture or pigmentation can happen for many reasons. Ageing, sun exposure, hormonal changes and previous inflammation can all influence the appearance of the skin.
However, sudden or unexplained changes should not automatically be assumed to be harmless. Areas that become unusually thickened, scaly, crusted, discoloured or different from the surrounding skin may require assessment.
Professional dermatological evaluation can help distinguish normal changes from conditions that need medical attention.
One of the most important aspects of skin health is knowing when to seek professional advice. It can be tempting to wait and see whether a concerning change disappears on its own. However, persistent or evolving skin changes deserve attention.
A dermatologist can assess your symptoms, consider your individual history and determine the most appropriate next step. Early professional assessment does not necessarily mean that a serious condition is present. Instead, it provides an opportunity to understand what is happening and receive appropriate guidance.

Your skin changes naturally throughout life, but not every change should be overlooked. Monitoring your skin regularly and being aware of new or evolving marks can help you recognise when professional advice may be needed.
If you notice a mole that changes, a new unusual spot, a lesion that does not heal, persistent itching or redness, or an unexplained change in skin texture or colour, consider seeking professional dermatological advice.
Healthy skin starts with awareness. By paying attention to changes and consulting an experienced dermatologist when necessary, you can take a proactive approach to your long-term skin health.
