What Is Photoaging?
Photoaging refers to skin ageing caused by repeated exposure to UV rays from the sun or artificial sources like tanning beds. Unlike natural ageing, which is influenced by genetic factors, photoaging occurs due to external environmental factors, primarily UV radiation. Even a few minutes of sun exposure daily can accumulate over time, leading to long-term skin damage.
How UV Radiation Damages the Skin
Early Signs of Sun Damage
Sun damage can show as early as your twenties, especially with excessive sun exposure. By the time you reach your 30s and 40s, the effects become more apparent, including:
The Impact of UV Exposure on Skin Structure
UV exposure accelerates the thinning of the epidermis, leading to increased water loss and decreased production of natural oils. This results in dry, rough, and leathery skin. Collagen, the protein responsible for skin's firmness, is also broken down, and new collagen production is impaired. This causes the skin to lose strength and turgor, making it more prone to wrinkling and sagging.
Sun Damage by Skin Type
Fair-skinned individuals show more pronounced signs of sun damage, including deeper wrinkles, uneven skin tone, and sagging.
People of colour are generally less susceptible to severe sun damage but may still experience fine lines, mottled complexions, and mid-face sagging, leading to under-eye bags.
Glogau Classification of Sun Damage
The Glogau Scale is a system used to classify the severity of photoaging:
Mild (28-35 years): Few wrinkles, minimal sunspots, no actinic keratosis, and little or no need for makeup.
Moderate (35-50 years): Early wrinkling, sallow complexion, some actinic keratosis (tender, dry red spots), and light makeup use.
Advanced (50-60 years): Persistent wrinkling, discolouration, telangiectasia, multiple actinic keratoses, and regular makeup use.
Severe (65+ years): Severe wrinkling, prominent sun damage, gravitational forces affecting skin, actinic keratosis, with or without skin cancer.

Preventing Sun Damage
Prevention is the best approach to avoiding sun damage. Consistent use of broad-spectrum sunscreen (SPF 30 or higher) is crucial, as is wearing protective clothing and seeking shade during peak sunlight hours. Incorporating antioxidant-rich skincare products can help mitigate some UV exposure damage.
Sun-damaged skin can lead to a range of cosmetic and health concerns. From pigmentation problems to skin cancer, the effects of UV exposure are cumulative and long-lasting. By understanding the signs of photoaging and seeking early treatment, you can maintain healthier, more youthful-looking skin.
