Exposure to the sun for a long period of time can result in several skin problems. They occur on the basis of heat, humidity and the rays of the sun. Here are the most common skin problems caused due to sun exposure:

Sunburn: Sunburns occur as a result of overexposure of the skin to the harmful ultraviolet rays of the sun. Melanin in the skin protects it from the sun s rays, but in case of overexposure, melanin fails to work and sunburn is caused. The symptoms of sunburn include the skin turning red, burning in the affected areas, skin tightness and a sensation of itching. Severe symptoms are blisters, chills, fever and fatigue.
Age spots: Age spots are caused due to overexposure to the sun. They are brown marks, which appear on the surface of the skin, especially in the arms, hands and other body parts. Age spots get more prevalent with ageing. Symptoms of this condition include brown and gray pigmentation on the skin surface. The pigmentation occurs in a circular shape and is flat on the skin.
Photosensitivity: This condition is also known as sun allergy. People with photosensitivity are likely to get burned from sun exposure very easily, and symptoms of sunburn are observed. Symptoms include red and pink skin rashes accompanied by itching and burning. The area gets scaly and blistered.
Moles: Moles occur commonly due to sun exposure. They may appear on any part of the body. Moles may vary from being harmless to cancerous. Common symptoms include raised skin and the skin tone changing into reddish brown or black. Moles are round in shape, and some moles are painful.
Solar elastosis: This condition is commonly known wrinkles and occurs when the elastic tissues of the skin get deteriorated due to sun exposure. The skin turns limp on account of no strength of the tissues and collagen. Wrinkles appear, and the skin seems loose and sagging. Deep lines are formed on the skin.
Skin cancer: Skin cancer accounts for being the most severe and fatal result of prolonged exposure to the sun without any kind of protection. There are many forms of skin cancer. The most primary skin cancers include Melanoma, basal cell carcinoma and squamous cell carcinoma.
Polymorphous light eruption: This condition, known as PMLE in short, affects women between the age group of twenty to forty. It also occurs in light sensitive people who spend more time under the sun. Symptoms include a red or pink, bumpy rash and raised areas on the skin surface. Itchiness and dry patches are indicated.
A large number of skin problems occur due to long hours of sun exposure. Some of these are chronic problems, which require proper treatment.

Skin Problems Caused due to Sun Exposure

A common skin condition, which causes the discoloration of your skin in patches across the face, melasma is more of a social embarrassment and cause for distress rather than being a serious condition. Although it affects men as well, studies have shown that over 90 percent of patients are women. It is also known as the mask of pregnancy as many pregnant women develop this skin condition.

Causes of Melasma
Primary causes of melasma have been attributed to various hormonal changes within the body. Let's look at some of the factors that may cause this disorder:
1. Pregnancy: This is often attributed as the leading cause of melasma, the primary cause has often been attributed to hormonal changes that a woman may experience due to pregnancy.

2. Treatments that may change hormonal balance: Women on contraceptive pills or who have implants such as intrauterine devices may also develop this disorder. This is due to the balance of estrogen and progesterone being changed within the body.

3. Sun exposure: Continued sun exposure may also lead to melasma. This is due to the activation of melanocytes within the body which start producing more melanin.

4. Stress: Long periods of stress on the body can also trigger hormonal changes and cause melasma.

5. Thyroid problems: If someone suffers from Hypothyroidism or low levels of the thyroid hormone, it can trigger other hormonal changes and also cause this skin disorder. 
It has also been noticed that people with generally a darker skin tone tend to get melasma and it is less common in people with fairer skin.

Certain characteristics of Melasma
Melasma develops in certain patterns which can be easily diagnosed either as spots on the skin similar to freckles or brown patches of skin that grow bigger. Some of these patterns are:
a. Malar pattern: This grows on the nose and cheeks
b. Mandibular pattern: Starts growing around the jaw line
c. Brachial melasma: This grows on the upper arms and shoulders
d. Lateral cheek pattern: Grows on the cheek on both sides of the face
e. Centrofacial pattern: Nose, upper lips, forehead and cheeks

Treatment of Melasma
Most women who develop melasma during pregnancy report that it goes away after childbirth. However certain forms of melasma may appear in non-pregnant women due to hormonal changes. Treating the underlying hormonal changes usually resolves the problem. However certain other methods may be required to resolve the issues such as skin creams, chemical peels, dermabrasion and microdermabrasion.

All About Melasma

Depending on the way you look at it, a mole can be a beauty spot or a blemish. For most people, facial moles are undesired. Moles can be described as clusters of pigmented skin cells. They appear in the form of dark spots on the skin that vary in size, color and texture. Apart from the face, moles appear commonly on the arms and legs but can affect any part of the body. In most cases, moles are harmless but in some cases, they may turn precancerous and need to be removed. However, most moles are removed for only cosmetic reasons. Moles can be removed through home remedies, surgery or laser treatment.

Mole removal depends on the type, size and location of the mole. When treated with lasers, layers of the mole are removed one by one by evaporating the affected cells. This does not cause any sort of bleeding and does not disturb healthy tissues adjacent to the mole. It is also considered to be a largely pain-free procedure but you may feel a slight tingling sensation. After the laser procedure, a scab forms over the affected area which later falls off. You may also notice slight swelling and redness in the area for a few days after the procedure.

Laser treatment for mole removal has a number of advantages.

As it is a non-invasive procedure, there are minimal chances of infection
Multiple moles can be treated in a single session
Laser beams can reach parts of the face, nose and ears that may be difficult to reach through other procedures.
There are minimal disturbance and injury to the adjacent healthy tissues
Healing is much faster than with other procedures
There is a very low chance of scarring
However, one of the biggest disadvantages of laser therapy is that it can only be used to treat surface moles as the laser beam cannot penetrate deep into the skin. Also, laser treatment, if not recommended in cases where the mole may be considered precancerous as the laser beam will destroy the mole leaving nothing that can be used for a biopsy. Lasers are also seldom used to treat large moles or birthmarks. The cost of removing a mole with laser treatment depends on the size, location and number of moles. In some cases, more than one session may be required and this too could influence the cost of the procedure.

Moles - How Laser Treatment Can Help You Get Rid Of Them?

Lymphedema is a condition that typically affects the arms and legs. The most common cause of this condition is damage to the lymph nodes or their removal as part of a cancer treatment program. There is no known cure for this condition. However, surgeries such as Vascularized lymph node transfer surgery may help deal with it better.

Vascularized lymph node transfer surgery involves replacing the affected lymph nodes with healthy lymph nodes from other parts of the body. This allows blood to flow more easily and restores or augments the lymphatic drainage system. In most cases, the healthy lymph nodes are harvested from the patient s groin. This procedure is relatively new, and its limits are still being explored by doctors. In cases of breast cancer that causes lymphedema in the upper limbs, this procedure may be performed along with breast reconstruction.

To be a viable candidate for this procedure the patient must have maximized control over lymphedema through other forms of lymphedema therapy. This therapy will need to be restarted after the surgery to ensure good results. The lymphedema diagnosis should also be less than 5 years old such that the patient s lymphedema is in its early stages.

As with any other surgical procedure, there are certain risks associated with this procedure. These can include

Reaction to anesthesia
Bleeding
Infection
Scarring at the site and poor healing
Damage to adjacent blood vessels
Nerve damage that can cause a temporary loss of sensation
Muscle weakness
Numbness ta the sites from where healthy lymph nodes were harvested
Risk of Lymphedema in the area where the lymph nodes were harvested from
After the surgery, the patient will need to keep pressure off the site where the lymph nodes have been transferred. The surgery site may be bandaged but compression garments will not need to be worn. On being discharged the patient may resume normal activities such as driving and work. High-intensity exercises that involve the use of the operated limb should be avoided for at least a month after the surgery. Compression garments should not be used until recommended by the doctor or a minimum of 2 weeks post-surgery. They will also need to schedule review consultations with the doctor. The schedule followed usually involves check-ups after 2 weeks, 1 month, 3 months, 6 months, 9 months and 1 year.

Everyone wants to have a bright and radiating skin. But blemishes and skin abnormalities are common and can occur due to lifestyle, diet or hormonal imbalances. Moles and warts are typical skin issues. But how do you tell them apart?

Moles   What are they?

Hardly ever causing pain, they appear in many different colours and can be bumpy or flat. Most often of red, brown or black colour, they occur as a result of skin pigmentation called melanocytes. They can be caused due to direct exposure to sunlight or due to genetic factors as well. They can appear in any part of the body and form slowly, taking a long time to grow.

Warts   What are they?

Small bumps or rough growth on the skin that appear in hands, legs, fingers, soles of the feet, face or in the genital area manifest as warts. They are white or pale. They occur as a result of harmful virus infection of Human Papilloma Virus (HPV) and hence, can be contagious. As opposed to moles, warts need to be removed quickly since a virus causes them.

How do you differentiate a mole from a wart?
Below are some common characteristics of each that can help you identify the skin problem:

Moles

Either flat or elevated from the skin, they are commonly referred to as beauty marks or birth marks.
At times, they have hair growing from them.
Usually, they have one colour   mostly on the darker side.
It cannot be transmitted between people.
They are generated by a collection of pigment cells in the body and darken during hormonal changes.
They tend to become cancerous and lead to melanoma.
Warts

They are harmless, yet contagious.
They have small black or dark dots in the centre that are tiny blood vessels, which provide them with nutrients.
They grow outwards on the skin with a scaly or bumpy deposit.
They can grow anywhere on the body, but are commonly found in feet, hands or fingers.
How to treat warts and moles?

The good news is that both warts and moles do not pose a grave risk to your health, but they are annoying and can turn dangerous in the long run. Especially with warts, you can give it to someone or acquire from someone, since it is a type of virus infection. So, seek medical assistance if you want them to be removed from your skin.

Be aware of the difference between warts and moles to know what you are dealing with. Consult a dermatologist to decide the right steps to remove it or not.

Warts vs. Moles - All You Need To Know!

Stretch marks don t only happen after childbirth, they can happen to anyone due to sudden changes in body size and weight. These are like ugly brown scars usually present on the stomach, thighs and hips. Truth be told, 90% of pregnant women will get stretch marks around these parts of their bodies.

These are some very easy things one can do to get reduce the appearance of stretch marks both old and new:

Moisturizing- Lotioning  up regularly can lighten stretch marks. Moisturizing helps to hydrate skin and this makes it easier for it to stretch. Moisturizing is very effective in lightening new stretch marks and can prevent new stretch marks from forming. Older stretch marks are more difficult to get rid of, though.

Retin A- Retin-A based creams are very effective against stretch marks. Retin-A works by boosting collagen production which helps the skin to stretch out and avoid tears which cause stretch marks. Pregnant and nursing women should not use Retinoic acid containing products, however. It also doesn t work on old stretch marks.

Glycolic Acid- This too can increase collagen production when used on skin. It is even more effective as alpha-hydroxy acid (AHA) which is used in chemical skin peels. You can use glycolic acid on skin even during pregnancy. Save your skin from sunlight when using glycolic acid.

Vitamin E Oil- This is touted as the miracle cure for stretch marks and it delivers especially when used on new stretch marks. Use it with an unscented moisturiser for better coverage.

Essential Oils- These are common home remedies for tackling stretch marks. One can use them directly on skin or mix with the carrier oil before use. These are the ones to go for:

Lavender

Rose

Frankincense

Vitamin C- You can take Vitamin C as a supplement to lighten stretch marks. You can also mix topical glycolic acid with Vitamin C and apply on the skin directly.

Lasers- These are the magic wands of cosmetic surgery and rightly so. Fresh stretch marks can be tackled using a pulsed dye laser also called vascular laser. The downsides of this laser treatment are that it works on early stretch marks and not on mature ones. It is also very expensive. This laser also doesn t work on darker skins.

Fractional Laser Treatment- These are very effective against older stretch marks. Your doctor will use this laser to resurface the older marks smoothing the surface of the skin. The treatment is very expensive and can cause hyper-pigmentation and scarring.

Abdominoplasty or Tummy Tuck- This is the only certain way to obliterate stretch marks. What the surgeon does is cut out swathes of skin from your abdomen with stretch marks. Downsides are that it s a risky procedure. There could be life-threatening complications and recovery takes long, sometimes as long as 3 to 6 months.
