The truth is that Sunblock does not prevent tanning completely, it only reduces the extent to which skin gets tanned.

In this blog we delve into understanding how tanning occurs, what are the short-term and long-term signs of tanning, and why it is still necessary to apply sunblock.

Understanding Tanning

How does it occur?

Tanning is a natural biological response of the skin to exposure to ultraviolet (UV) radiation from the sun. The process is initiated by the body's attempt to protect itself from the potentially harmful effects of UV rays. When the skin is exposed to sunlight, specialized cells called melanocytes, located in the epidermis (the outer layer of the skin), produce a pigment known as melanin. Melanin is responsible for the colour of the skin, hair, and eyes.

UV Radiation & Tanning

UV radiation comes in two primary forms: UVA and UVB. UVA rays penetrate the skin more deeply and are associated with premature ageing, while UVB rays are responsible for sunburns. When the skin is exposed to UV radiation, it triggers the activation of melanin production. This melanin absorbs the UV rays, serving as a natural defence mechanism to prevent cellular damage.

Signs Of Tanning

Short-term signs

Melanin Production: UV radiation stimulates the production of melanin, the pigment responsible for skin colour. This darkening of the skin is the visible aspect of a tan.

Sunburn: Excessive exposure to UV radiation can cause sunburn, characterised by redness, pain, and inflammation of the skin.

Dryness and Peeling: Sun-exposed skin may become dry and start to peel as a response to UV damage.

Long-term signs

Premature ageing: Chronic exposure to UV radiation accelerates the ageing process of the skin. This can lead to wrinkles, fine lines, and other signs of premature ageing.

Skin damage: UV rays can damage the DNA in skin cells, increasing the risk of skin cancers such as melanoma, basal cell carcinoma, and squamous cell carcinoma.

Uneven pigmentation: Prolonged sun exposure can result in uneven pigmentation, causing dark spots, freckles, and sunspots.

Loss of elasticity: UV radiation breaks down collagen and elastin fibres in the skin, leading to a loss of skin elasticity and firmness. 

What is Sunblock?

Sunblock, commonly referred to as sun cream or sunscreen, is a protective substance for your skin against the sun's harmful rays. These lotions or creams contain a photoprotective topical substance that reflects the sun's ultraviolet radiation, serving as a defence mechanism to shield your skin from sunburn and tanning. Dermatologists and skincare experts universally recommend incorporating sunblock into your daily skincare routine to ensure comprehensive protection.

Why is Sunblock Important?

Prevents Sunburn: Sunblock helps to prevent sunburn by blocking the harmful effects of UVB rays.

Minimizes Premature Ageing: Exposure to UV rays accelerates the ageing process, leading to wrinkles and fine lines. Sunblock aids in preventing premature ageing caused by sun damage.

Reduces Risk of Skin Cancer: Prolonged exposure to UV radiation is a major risk factor for skin cancer. Sunblock acts as a barrier, minimizing this risk.

Maintains Skin Health: Consistent use of sunblock contributes to overall skin health by protecting against sun-induced damage.

Tips On How To Reduce the Effects of Tanning

Proper Sunblock Application: Ensure thorough and even application of sunblock to all exposed areas of the skin.

Reapplication of Sunblock: Sunblock’s effectiveness diminishes over time, especially after swimming or sweating. Reapply every two hours or more frequently if engaged in water activities.

Seek Shade: Limit direct sun exposure during peak hours (10 a.m. to 4 p.m.) when UV radiation is most intense.

Protective Clothing: Wear hats, sunglasses, and clothing with UPF (Ultraviolet Protection Factor) for added defence.

In essence, sunblock is your shield against potential sun-related risks. Understanding the nuances of tanning and embracing daily sunblock use is key to a healthy balance between enjoying the sun and safeguarding your skin. So, stay radiant responsibly and let your sunblock be your daily armour. Read our blogs on how dark skin tans and the need for sunscreen for dark skin tones to know more.
