The Hidden Price of a Summer Tan: Dubai Dermatologist Warns of 7 Skin Health Risks, Including Premature Ageing and Cancer
Dr Sara Khalil, Dermatology and Aesthetic Medicine Physician, warns that repeated tanning and excessive ultraviolet exposure can cause lasting skin damage, from pigmentation and premature wrinkles to precancerous lesions and skin cancer.
Dubai: For many beachgoers, achieving a golden summer tan is considered a beauty goal. But dermatologists warn that the bronzed appearance often associated with healthy, glowing skin may actually be a visible sign of damage caused by ultraviolet (UV) radiation.
Dr Sara Khalil, Dermatology and Aesthetic Medicine Physician, said repeated exposure to the sun without adequate protection can have consequences extending far beyond temporary sunburn.
While some effects, such as redness and irritation, may appear within hours, others develop gradually over years, potentially resulting in premature ageing, persistent pigmentation, precancerous skin changes and an increased risk of skin cancer.
“The concern is that people often associate tanned skin with beauty and good health, without recognising that tanning caused by ultraviolet exposure is actually a protective response to skin damage. The effects can accumulate silently over time, even when there is no obvious sunburn,” she explained.
Is a tan really a sign of healthy skin?
According to Dr Khalil, one of the most widespread misconceptions is that gradual tanning is harmless, particularly if the skin does not become red or painful.
In reality, tanning occurs when the skin increases melanin production in response to ultraviolet radiation.
Although melanin provides some natural protection, the tanning process itself indicates that the skin has been exposed to potentially damaging UV radiation.
“A tan should not be mistaken for evidence of healthy skin. Even without visible sunburn, repeated ultraviolet exposure can contribute to cellular damage that may become apparent much later,” Dr Khalil said.
She explained that cumulative ultraviolet exposure can damage DNA within skin cells, contributing to the development of certain skin cancers.
Seven health risks associated with excessive tanning
Dr Khalil identified several important skin problems linked to repeated and excessive UV exposure.
- Skin pigmentation: Uneven skin tone and dark patches caused or aggravated by repeated sun exposure.
- Melasma and freckles: Increased visibility or worsening of existing pigmentation, particularly among susceptible individuals.
- Premature skin ageing: Early development of visible ageing changes associated with long-term sun damage.
- Wrinkles, sagging and loss of elasticity: Damage to collagen and elastin fibres that help maintain skin firmness.
- Worsening of photosensitive skin conditions: Increased symptoms among people with skin disorders aggravated by sunlight.
- Precancerous skin lesions: Development of abnormalities such as actinic keratoses, which require medical evaluation.
- Skin cancer: Increased risk of several forms of skin cancer, including basal cell carcinoma, squamous cell carcinoma and melanoma.
She stressed that many of these conditions develop gradually, meaning people may not immediately recognise the long-term consequences of repeated tanning.
How sunlight can make skin age faster
Dr Khalil explained that ultraviolet radiation contributes to a process known as photoageing, which can accelerate visible skin ageing independently of the body’s natural ageing process.
Long-term UV exposure damages collagen and elastin, two essential structural proteins responsible for skin strength, firmness and elasticity.
“Chronic sun exposure can break down collagen and elastin, leading to premature wrinkles, sagging and loss of skin elasticity. These changes may appear years earlier than expected in people who repeatedly expose their skin to ultraviolet radiation without adequate protection,” she said.
She added that persistent dark spots, uneven skin texture and reduced skin firmness may all be signs of accumulated sun damage.
Does darker skin provide complete protection?
Another misconception, according to Dr Khalil, is that people with naturally darker skin do not need sunscreen.
Although higher melanin levels provide some natural protection against ultraviolet radiation, they do not eliminate the risk of skin damage.
“Every skin type can experience ultraviolet damage. The level of risk may differ, but no skin colour offers complete protection from the harmful effects of excessive sun exposure,” she explained.
People with fair skin generally face a higher risk of several UV-related skin cancers, but individuals with darker skin can also develop skin cancer and other forms of sun damage.
Six groups who should avoid intentional tanning
Dr Khalil highlighted six groups for whom deliberate tanning is particularly concerning: children and teenagers; people with fair skin; individuals with a personal or family history of skin cancer; those with melasma or pigmentation disorders; people with photosensitive skin conditions; and individuals taking medications that increase sensitivity to ultraviolet radiation.
She stressed that deliberate tanning should not be considered a safe cosmetic practice, even when sun exposure is spread across several shorter sessions.
How social media is fuelling the tanning trend
Dr Khalil also expressed concern about the influence of social media in promoting bronzed skin as an ideal beauty standard.
Images of sun-kissed skin, beach holidays and tanning routines can encourage young people to spend extended periods outdoors without fully understanding the potential consequences.
“The popularity of tanning on social media can create the impression that darker, sun-tanned skin is a symbol of beauty or vitality. However, people need to understand that achieving this appearance through repeated ultraviolet exposure can come at a long-term cost to their skin health,” she said.
How to protect your skin during the UAE summer
Dr Khalil recommended using broad-spectrum sunscreen with an SPF of at least 30, reapplying it approximately every two hours during sun exposure and after swimming or sweating, according to product instructions.
She also advised avoiding prolonged direct sunlight during peak UV hours, seeking shade and wearing protective clothing, wide-brimmed hats and appropriate sunglasses.
People should seek dermatological assessment if they notice a new or changing mole, an unusual skin growth or a lesion that repeatedly bleeds or fails to heal.
Healthy skin matters more than a temporary tan
Dr Khalil emphasised that enjoying outdoor activities does not have to mean exposing the skin to unnecessary ultraviolet damage.
“Bronzed skin may be a temporary beauty trend, but the damage caused by excessive ultraviolet exposure can last for years. Protecting the skin from the sun is one of the most important steps people can take to maintain healthy, youthful-looking skin and reduce their long-term risk of skin cancer,” she concluded.
