The harmful effects of the ultraviolet rays of the Sun are known globally.

While on the one hand, Sun exposure becomes necessary for humans, its overdose might cause severe to mild health issues.

These health problems are associated majorly with skin ranging from early aging signs to even skin cancer.

This article shall discuss how harmful the Sun can be towards your skin and how it induces or aggravates acne breakouts.

It shall further elaborate ways of protecting your skin from damage.

How Sun Over Exposure Harm your Skin?

Sun is responsible for major changes in the texture and structure of the skin.

The harmful ultraviolet rays that it emits tends to damage the elastin fiber making the skin saggy and lose and giving it a major characteristic of the aging effect on skin, that of wrinkles.

The Sun also causes bruises and scarring on your skin which becomes visible only after a lapse in time and also tends to tear easily.

Furthermore, exposure to the harmful rays of the Sun decreases the functional ability of the skin’s immune system which therefore is not able to fight properly and may even give rise to lesions which may also be pre-cancerous.

It may also result in the development of tumors that can be either benign or cancerous depending on how much exposed the sun has been.

Excessive exposure also causes discoloration or pigmentation which often gives your skin and uneven and patchy tone and texture.

It may also give rise to a condition known as telangiectasias which is nothing but the growth of small blood vessels under the surface of the outer layer of your skin.

It may also inhibit collagen formation which will then severely damage the skin and slow down its healing process.

Can Sun Exposure Promote Acne?

There have been various studies that have tried to establish some link between exposure to the Sun and acne breakouts.

The results of such studies have however been contradictory in nature.

While some argue that exposure to the Sun actually heals acne, other argues for its opposite saying that it aggravates acne.

There have been established many direct and indirect links between the two and some of them are discussed in this section.

It has been suggested that the ultraviolet rays of the Sun are known to destroy the skin cells which function towards providing immunity to the skin and preventing any damage to it.

The weakening of the skin’s immunity makes it difficult for the body to fight the acne-causing bacteria which thereby multiply and spread.

Excessive exposure also tends to make the sebaceous glands bigger in size, thereby enlarging the pores and ensuring more sebum accumulation.

The excessive sebum accumulation in the blocked pores of the skin provides the required environment for the growth and multiplication of acne bacteria and microbes.

It has been noticed that continuous, strong and regular exposure to the Sun’s rays tends to enlarge the skin pores which therefore becomes more capable a larger amount of sebum accumulation.

It also affects an increased production of whiteheads and blackheads which are forms of non-inflammatory acne and often contribute towards the breakout of inflammatory acne.

Exposure to the harmful ultraviolet rays of the Sun tends to affect a narrowing down of the size of blood vessels under the surface of the skin.

This decreased size of the passage of blood vessel tends to reduce if not completely inhibit, oxygen supply along with the supply of vitamins, minerals and other nutrients to the skin.

This, in turn, affects the health of the skin which is left not strong enough to fight the acne-causing bacteria or microbes.

The decreased blood flow also induces dullness in the skin which loses its entire glow as a result, making it more vulnerable.

One of the major factors that contribute towards acne breakout due to the exposure to Sun is the effect its rays have on collagen formation.

The Sun tends to break down the formation of collagen fibre which as a result causes the formation of elastin.

This elastin induces the production of metalloproteinase.

This substance, at times, tends to stimulate the breakdown of collagen fibre causing an abnormal accumulation of collagen which often results in the development of wrinkles and disorganized fibers.

Additionally, exposure to ultraviolet rays stimulates the production of free radical which in the absence of an antioxidant, inhibits cell function and thereby collagen formation thereby slowing down the process of healing of the damaged skin.

The breakdown of collagen fibre is induced due to the production of metalloproteinase, whose action has been discussed in the last paragraph.

Exposure to sunlight gives rise to certain chemicals that are known to inhibit immune factors.

This specifically includes creating an obstacle in the functioning of white blood cells, T lymphocytes and Langerhams cells which are good defenders of the skin.

Lastly, though not the least significant is the role Sun’s rays play in obstructing cell death also otherwise known as the process of apoptosis.

As per this process, the extremely damaged cells, very simply, kill themselves so that new cells are formed in its place that can work and protect better.

The ultraviolet rays of the Sun do not let the cells commit suicide while on the other hand, promoting the growth of these damaged cells which can, later on, become even cancerous.

Thus in a way, it obstructs the healing process and aggravates the severe condition of the damaged skin due to acne.

How to protect your skin from the Sun?

The increasing danger that the ultraviolet rays emitted by the Sun have made it necessary for people to be conscious and protect themselves from these harmful rays.

Enumerated below are certain ways in which you can protect yourself and more importantly your skin from getting damaged by the Sun:

  • It is of utmost importance that you must always wear a sunscreen lotion before going out in the Sun. It has usually been suggested that you use a sunscreen with an SPF (Sun Protection Factor) of more than or equal to 30. If you have long been suffering from acne,
  • it is better to use a non-comedogenic lotion as it possibly will not clog your skin pores further. It is also usually advised that you use a sunscreen that provides protection against both UV A and UV B rays of the Sun.
  • If it is not possible to completely avoid the Sun, you must make sure to wear protective clothing while going out in the sun. This is particularly important when you are undergoing some acne medication as it tends to make your skin sensitive to the Sun.
  • The Sun shines most mightily between 10 a.m to 4 p.m. it is therefore advised that you seek a shady place at such a time, if out in the open.
  • It is foolish to assume that when around water or snow, Sun damage can be avoided or your skin protected even if you do not maintain any protection. The water or snow tends to reflect the rays of the sun which can cause sunburn without you realizing. Sand also has the same effect.
  • If your skin is sensitive to the Sun, use other supplementary sources of vitamin D rather than going out to manufacture it in the Sun
  • Try avoiding tanning beds as much as possible as it tends to have the same effect as the ultraviolet rays of the Sun.
  • Wear clothes that tend to block out the sunlight rather than absorbing it. Such clothes are mostly tightly woven. Darker colors tend to block out the sunlight while lighter colours do not really minimize exposure to your body. It is also always better to cover your sleeves and legs completely before going out in the sun.
  • A wide-brimmed hat while going out in the sun is a good option than most others because it covers up major portions of your face and head and also provides a kind of shade.
  • Get used to wearing sunglasses that usually block out both UV A and UV B rays from the Sun

It is very important to keep your skin hydrated throughout.

When ignored, it might cause severe dryness of the skin. Dry skin gets worse in the Sun.

It is therefore important that you keep your skin hydrated by moisturizing it at regular intervals while at the same time doing so internally by drinking water, especially in summers.

Summary

Though the Sun might seem helpful initially by affecting a reduction in scarring and pitted pigmentation, such effects are temporary.

It begins to damage your skin without you realizing it and can really speed up the aging process.

The harmful ultraviolet rays of the Sun are particularly efficient in causing a deterioration of the health of the skin in various ways mentioned above.

It not only aggravates the frequency and severity of acne breakouts but also worsens it by affecting further scarring and skin damage.

It is therefore advisable for the benefit of your skin and its health that you restrict sun exposure to the minimal required dose and adopt ways of protecting yourself against its harmful effects.
