THE MBR SUN PROTECTION CARE

SUNLIGHT

MBR® fényvédelem

Sunlight is made up of heat rays, light rays and UV rays.

Heat rays (infrared) penetrate the deepest into an organism and are perceived as heat. This promotes circulation.

Light rays (visible rays which we perceive as “sunlight”) enable us to see.

UV rays (short wave light with the highest level of energy) are invisible and are responsible for change processes, e.g. tanning and burning of the skin.

Long wave UVA rays (320 – 400nm)
– immediate tanning of the skin
These are responsible for long-term damage to the skin, making it inelastic, reducing its ability to bind moisture and also causing premature aging of the skin with the formation of wrinkles. They penetrate into the connective tissues where they weaken the elastic and collagen fibers. Excessive exposure to sunlight is the most common cause of skin cancer.

Short wave UVB rays (285 – 320nm)
– long lasting pigmentation
Excessive exposure to these rays can cause immediate damage to the skin, the first sign of damage being excessive sunburn. They also damage the structure of skin cells.

UVC rays (200 – 285nm)
are of no significance as far as sunbathing is concerned. Because they are absorbed outside the atmosphere, they do not affect people through natural sunlight.

UV INDEX

MBR® Sun Protection

Der UV-Index gibt die sonnenbrandwirksame solare Bestrahlungsstärke an und variiert durch Faktoren wie:
– Cloudiness
– Sunshine (with geographical latitude, day and season)
– The geographical altitude
– The thickness of the ozone layer

In predictions, the maximum expected value for the day is indicated. In the German region UV indices between five and eight are usual in the months from May to August. Around 10 and 16 o’clock, the values are typically about half as large.

Maximum values for the respective days of the year, can be predicted worldwide and should be taken into account, for example, during holiday planning. Here you can find information on the UV indices that are predicted worldwide.

SKIN TYPES

MBR Sun Guide System

is a term used to indicate the period of time throughout the day in which your skin can be exposed to the sun without sustaining sunburns.

To determine this period of time, it is crucial to know your skin type. The Fitzpatrick system is the most common classification system for skin types.

–

Type I – Celtic type

self-protection time: < 10 min

• very light skin colour
• ginger or light blond hair
• blue, green, or light grey eyes
• freckled
• does not tan, develops freckles, very frequent sunburns

Recommended light protection factor: 15 for UV indexes of 3–4; 25–35for UV indexes of 9 and above.

Type II – Nordic type
Self-protection time: 10 – 20 min

• Light skin colour
• Blond or light brown hair
• Blue, grey, or green eyes
• Frequently freckled
• Tans slowly, minimal tan
• Frequent sunburns

Recommended light protection factor: 10–15 for UV indexes of 3–4; 20–25 for UV indexes of 9 and above.

Type III – Mixed type
Self-protection time: 20 – 30 min

• Medium skin colour
• Dark or light brown, sometimes blond or black hair
• Brown (blue, green, or grey) eyes
• Barely freckled
• Tans slowly but progressively, up to a light brown tone
• Occasional sunburns

Recommended light protection factor: 10–15 for UV indexes of 3–4; 15-20 for UV indexes of 9 and above.

Type IV – Mediterranean type
Self-protection time: < 30 min

• Light brown or olive skin when untanned
• Brown eyes
• Brown or black hair
• Not freckled
• Tans quickly to a medium brown tone
• Infrequent sunburns

Recommended light protection factor: 10 for UV indexes of 3–4; 15 for UV indexes of 9 and above.

Type V – Dark skin types
Self-protection time: < 60 min

• Dark skin when untanned, frequently with a grey hue
• Dark eyes
• black hair
• not freckled
• tans quickly to a dark brown tone
• hardly any sunburns

Recommended light protection factor: 4 for UV indexes of 3–4; 8 for UV indexes of 9 and above.

Type VI – Black skin types
Self-protection time: < 90 min

• Dark brown to black skin when untanned
• Black eyes
• Black hair
• Not freckled
• Virtually no sunburns

Recommended light protection factor: 2 for UV indexes of 3–4; 4 for UV indexes of 9 and above.

What is my skin type?

Skin type can be determined by factors such as your skin and hair colour, absence or presence of freckles, and the colour of your nipples. Generally, light skin/hair/nipples and increased numbers of freckles indicate that your skin has a short self-protection period.

But these indicators alone do not provide a detailed skin-type analysis, which ultimately depends on the eumelanin content of your skin (measured in per cent). This eumelanin content can and should be determined by your dermatologist in order to reach a definite conclusion about your skin type.

HOW DOES THE SKIN TAN?

An individual’s skin color is a result of a combination of factors: skin circulation, the color of the corneal layer and the amount of pigment in the skin. The most important of these is the pigment melanin, which can range in color from buff to black. The pigment melanin is formed by special pigment cells called melanocytes. These cells are found in the lowest basal layer alongside the epidermis cells.
The pigment cells produce melanin, some of which is delivered to other cells in the form of tiny grains. It is only through the process of cell regeneration in the basal layer that the grains of melanin are carried by neighboring cells and move up in the skin. Through the normal process of regeneration of the epidermis, the grains of melanin reach the surface corneal layer, where they are shed with other horny skin cells.

How is melanin formed in cells?

The colorless precursor of melanin is the amino acid tyrosine. Following a series of changes, catalyzed by the cupreous skin enzyme tyrosinase and oxygen, this amino acid becomes melanin. However, this change is only activated and carried out by exposure to sunlight. Although pigment production does not depend on the number of pigment cells, it does however depend on the rate at which the pigment cells metabolize. Individuals with fair and dark skin do not differ in the number of pigment-forming cells they have; there is however a large difference in the rate of metabolism and activity of pigment cells.

THE RIGHT SUNBATHING

In order to enjoy the sun undisturbed, you should always remember that …

… a child’s skin is ten times thinner than an adult’s skin.
Babies and small children may not be exposed directly to the sun’s radiation. They must be dressed in suitable clothing and protected with a high sun protection factor (min. SPF 25).

… the sun’s rays are up to 60% stronger near the equator.

UV rays increase by 20% for every 1000m above sea level. water, ice, snow, light sand and rocks reflect rays and increase the effect of UV rays by up to 80%. high fog, which is typical in mountains, intensifies UV rays by up to 60%.

… the sun’s rays are at their strongest during the middle.
even if it is overcast, up to 40% of UV rays still get through. Avoid intense afternoon sun. Do not sit out too long in the sun and always choose a sunscreen appropriate for your skin type and for the region where you will be vacationing. Always apply cream before sun exposure. Generously apply sunscreen and wait at least 20 minutes before sunbathing. Repeat application regularly, especially after swimming, perspiring, and drying off. Give your skin time to get used to the sun, use a higher sun protection factor during the first days of your vacation.

… men have to protect themselves just as much as women. Even though men naturally have thicker, more resistant skin.

Sunscreens do not offer 100% protection from the risks of excessive sun exposure. Dermatologists require sun exposure to be sensibly addressed.
