How to protect your skin from sunlight

Although the sun is excellent for promoting vitamin D production in your body, it also carries a huge risk. The effects of ultraviolet (UV) rays, a component of solar radiation that is particularly rich in energy, is that it can damage the skin and eyes. However, it is not just invisible UV rays which are harmful to the skin. There are some portions of visible light that cause harmful effects on the skin, called HEV light.

However, it is not just invisible UV rays which are harmful to the skin. There are some portions of visible light that cause harmful effects on the skin, called HEV light. HEV (High Energy Visible) light is a high-frequency light with a wavelength between 400 and 500 nm in the visible spectrum (blue / violet). At the epidermal tissue and dermal level, it causes the formation of reactive oxygen species (ROS), responsible for DNA damage and activation of enzymes metalloproteases matrix (MMPs) that degrade the dermal fibres and can cause premature ageing. High-Energy Visible (HEV) Light is a form of light believed to cause long-term skin damage as significant as UVA and UVB combined. HEV damage is insidious and long-term. While there may be no immediate signs such as redness or swelling, repeated exposure over time can lead to premature ageing and even skin cancer.

While it is well known that sunlight can age and damage skin, not everyone is aware that sunscreens cannot provide complete protection against harmful UVA, UVB and HEV rays.

The new Oclipse Sun Spray SPF50 and Oclipse Smart Tone Broad-Spectrum Sunscreen SPF50 protect against harmful UVA and UVB rays and HEV light and help guard skin against photo-damage and future signs of ageing.

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.

Rosacea: What causes it? (Infographic)

Acne rosacea, or simply rosacea, is a chronic inflammatory disease of the skin (dermatitis) that mainly affects the central part of the face (cheeks, nose and forehead).

The skin of the face manifests red papules, pustules and telangiectasia and, often, there is a thickening (hypertrophy) of the tissues, which sometimes becomes particularly evident in the nose, giving it a swollen and bulbous appearance (rhinophyma). In addition to skin problems, rosacea can cause, although rarely, ocular manifestations (eg. Blepharoconjunctivitis) and keratitis.

Even though it can look similar to acne, the rosacea condition differs primarily with the age of onset and the absence of comedones.

This dermatosis occurs mainly in middle-aged people and those with pale skin and light hair. Women are affected more than men and sometimes several members of the same family are affected.

It is important to mention that rosacea is not a contagious disease, nor is its onset connected with poor hygiene.

Since this is a progressive inflammatory dermatoses, the treatment should be started as early as possible. If the problem is underestimated or untreated, the disease progresses and can disfigure the face.

ZO Skin Health and Medical products are formulated for treating the symptoms of rosacea skin condition, such as flushing, redness, prominent blood vessels, papules and pustules associated with acne.

What is acne? (INFOGRAPHIC)

Acne vulgaris (acne) is an inflammatory dermatosis of the skin that affects the hair follicle and its attached sebaceous gland and is characterized by the presence of pimples on the face (99%), the back (60%) and the chest (15%). The symptoms of acne include: seborrhea, comedones, pustules, papules, nodules and cysts.

Teenagers are particularly prone to acne (with a peak around 17 years of age) as well as young Caucasian adults, while it results less common in African people and even less in Asiatic people.
Acne vulgaris is different from rosacea acne and erythematosa acne. In acne, the clinical element is the blackhead that, inflamed, leads the appearance of papules and pustules, commonly called pimples.
In rosacea acne the characteristic condition is the dilatation of blood vessels on facial skin (telangiectasia), linked to skin conditions (acne vulgaris, seborrhea) and/or can affect eyes (blepharitis, keratitis).

Unlike acne vulgaris that appears mainly in teenagers and young adults between 12 and 30 years, rosacea acne occurs in adults between 30 and 50 years old, especially in women.
In severe forms of acne, the skin damage can be permanent and leads to hyperpigmentation and presence of scars.

ZO Skin Health and Medical offers a wide range of products designed to remove oil, normalize pore size, help smooth skin’s surface, and reduce inflammation and irritation.
ZO Medical products are exclusively available through a physician.
