How Often Should You Apply Sunscreen?

We all know by now that SPF is an essential for any summer holiday. It protects your skin from UV rays, health risks as well as premature skin ageing. But how often do you need to apply sunscreen, to ensure that it is at its utmost effective?

Before Sun Exposure

A common mistake many make is waiting till they are lying out on their sunbed before they begin to apply sunscreen. Yet, in fact, you need to apply sunscreen about 20-30 minutes before you expose your skin to the sun. This will ensure that the ingredients in the SPF can really begin to work the moment you step outside.

During Sun Exposure

SPF should be reapplied every 2 hours. If you go swimming, play a sport or simply sweat from the summer heat, sunscreen should be immediately reapplied.

When it isn’t Sunny

Even when it is cold or cloudy, you must still wear SPF. It is a misconception that UV rays are non-existent or cannot penetrate the skin when it isn’t hot or sunny. You must always apply sunscreen because up to 40 percent of the sun’s ultraviolet radiation reaches the earth on a completely cloudy day.

The Dangers of Sun Exposure

So you’ve got a holiday coming up and you can’t wait to get a healthy tan. We hate to be the bearer of bad news, but you might want to re-think getting that sun-kissed skin. Find out everything you need to know about the dangers of sun exposure and the skin problems that can arise because of it. dangers of sun exposure

What makes sun exposure so problematic?

Sun exposure induces chronic inflammation. This type of inflammation is a destructive process that leads to abnormal cellular function and weakens skin’s immunity, specifically the immunity that helps skin repair itself. Very simple, sun exposure weakens your skin’s ability to repair damaged DNA and with repeated exposure, more damaged DNA-mutated cells appear. These are initially pre-cancerous cells that will eventually mutate into skin cancer. So, in the short term, you may think that holiday glow makes you look healthy, but in the long-run, it’s actually extremely dangerous for your skin.

Sun exposure also disturbs many cellular functions and normal skin texture, resulting in:

  • Discoloration.
  • Dryness and roughness.
  • Sensitivity and redness.
  • Damaged skin collagen and elastin, which will lead to a leathery skin texture and accelerated skin ageing (earlier and deeper wrinkles and folds), later in life.

Sun Exposure Before Age 20

Think you’re safe from sun damage before the age 20? Think again.

The skin is rich with vitality due to proper and active cellular function and repair, but this doesn’t mean your skin is damage-proof. The earliest sun-damaging effect seen in this age group is the appearance of freckles in light-skinned individuals. This freckling is an indicator of early photosensitivity and susceptibility to severe sun damage later in life. This can affect skin texture and lead to a high possibility of skin cancer. So, unfortunately, you may think your freckles look ‘cute’, but they’re actually an indicator of sun damage.

Those who tan well may have less chance of skin cancer in the future as tanning represents the presence of strong natural resistance (due to stable, real melanin, also known as eumelanin). However, they will suffer from severe textural damage, resulting in skin with a leathery feel and solar elastosis. So, no one escapes sun damage if the skin is not protected at an early age. Even in individuals who tan well, as tanned skin is essentially the skin screaming “help.”

Sun Exposure After Age 20

After age 20, sun damage is manifested by skin dullness, discoloration and roughness. In your 30s and 40s, it is characterised by the appearance of actinic keratosis and lentigines. During your 50s, full-blown textural damage and precancerous lesions are evident, as is the appearance of skin cancer in some.

Those with fair skin will experience more damage than darker skin. Similarly, for those with thin skin, you will find that you show earlier sun damage signs compared to thick skin.

What’s more, if you suffer from other skin problems such as acne or rosacea, these skin diseases can increase susceptibility to sun damage. Equally, certain diseases and genetic disorders (i.e. lupus, xeroderma pigmentosum) can increase photosensitivity, accelerate the appearance of sun damage and result in skin cancer.

Keep note that sun-damaging effects are stronger near water, snow or at high altitudes.

Product Spotlight: SPF

Photoageing is one of the biggest causes of premature ageing leading to an increase in fine lines, wrinkles, loss of elasticity and pigmentation. Sun damage is cumulative, the damage over the years from daily exposure to UV rays is not always externally visible. Early pigmentation damage occurs within the deeper layers of the skin and becomes more apparent on the surface as we age. The skin loses its ability to repair itself, prohibiting the breakdown and production of collagen, as well as the elasticity of the skin weakening, resulting in leathery and wrinkled skin.

With options for every skin type and lifestyle, ZO Skin Health’s sunscreens provide protection from the harmful effects of the sun while also improving the health of your skin.

How To Get Vitamin D Safely From The Sun

vitamin d

Why is vitamin D important?

Vitamin D is vital for healthy bones, teeth, and muscles, as it helps the body to absorb calcium and phosphate from your diet. Suffering from a vitamin D deficiency could lead to some really bad health problems like soft and weak bones. The sun is one of the best sources for this vitamin but is also one of the biggest causes of skin cancer. Consequently, you just need to find the right balance between a healthy dose of sunlight and excessive sun exposure.

How long can you be under the sun?

Most people can make enough vitamin D from being out in the sun daily for short periods. What’s more, you only need to have your forearms, hands or lowers legs uncovered to get an effective amount of vitamin D production. So we are sorry to say that for those who love to sunbathe, it is both detrimental to your health as well as being an entirely unnecessary risk.

What factors are at play with vitamin production?

It is important to remember that there are several factors that can impact how much vitamin D is made from sunlight, such as your skin colour. People with dark skin will need to spend longer in the sun to produce the same amount of vitamin D as someone with lighter skin.

However, regardless of skin colour, you should still be vigilant about protecting your skin from burning. According to Cancer Research UK, though people with naturally brown or black skin are less likely to develop skin cancer, it does not make them invincible to it. Often, the most common parts of the body that are not exposed such as the soles of the feet can be affected by skin cancer.

How to protect your skin from sun damage. INFOGRAPHIC

In our society, tanned skin is often synonymous with healthy, young and beautiful skin. Unfortunately,  repeated exposure to the sun leaves indelible marks, even on the most perfect of skin.

Regardless of whether you skin has burnt, reddened or tanned from the sun, they are all symptoms of your immune systems response to ultraviolet radiation, which is a consequence of RNA damage to skin cells.

Ultraviolet rays are divided into three categories, according to their wavelength: UVA, UVB and UVC.  UVC rays are not a problem, thanks to the atmosphere that filters them. However, UVA rays can still penetrate the dermis, while UVB rays reach the surface layer of the skin and discharge all their energy (higher than UVA) into epidermal cells and especially DNA. The sunburn you experience is caused by UVB rays. Nevertheless, though UVA rays do not cause sunburn, in the long run, they can lead to a degeneration of elastic fibres and collagen in the dermis, which results in a loss of elasticity in the skin.

The target of solar radiation is cellular DNA and can cause a considerable amount of damage to the double helix. In response, your body begins the production of free radicals, releasing destructive enzymes called hydrolases. This phenomenon is called photo-ageing, the biological process by which the sun’s rays causes premature ageing at the deepest point of the skin.

It is important to protect your skin from UVA and UVB rays with a good sunscreen. If the skin is sensitive it will require a cream with a sun protection factor (SPF) of at least 30.

ZO Skin Health and Medical offer effective daily solutions to minimise UV damage, prevent DNA damage and protect the skin from environmental aggressors to improve overall skin health.
