In recent years, benign skin lesions occur at younger people more and more often.


These changes of skin colour (spots) are a result of modern way of leaving (excessive sun exposure) and occur in areas of the body, such as the face, hands, and the upper part of the body.

Prevention can limit their appearance in younger people, as in older people spots are usually the result of actual aging of the cells, especially in predisposed individuals.

Age or Sun Spots

These are parts of the skin with increased melanin production. They should not be confused with macules (melasma), and despite their name -age spots or sun spots- they can also occur at a young age.

They are due to hereditary predisposition and due to the cumulative chronic unprotected sun exposure.

They gradually increase both in number and size, and they are aggravated by the sun.

Age spots or sun spots usually appear on the face, arms, chest and back.

Correct diagnosis

Although spots are usually benign skin lesions, the correct diagnosis by a dermatologist is necessary, based on which the appropriate treatment method can be selected depending on the type of lesion.

Always according to the philosophy of providing a full treatment strategy, initially the correct diagnosis is established so that to ensure that Laser use is indicated to achieve the best possible result.


Nowadays, the use of Dermatological Q-Switched Lasers, offers excellent results safely.

Contrary to the “classical” methods of cryosurgery, electrocoagulation, abrasion and old fashioned lasers which cannot eliminate selectively the target lesion, the sophisticated technology of Q-Switched Lasers allows selective action and elimination of the spots, leaving intact the surrounding healthy skin.

Three different types of advanced Lasers are used in combination (Q-Switched Alexandrite 755nm, Q-Switched KTP 2nd Harmonics 532nm, and Q-Switched Nd:YAG 1064nm), so that by choosing different wavelengths, according to the type and the depth of the disorder, the best outcome is ensured, regardless of the size, type and location of the spots

Possible side effects

The emission of the harmless beam of light of Q-Switched Lasers is only emitted for a really small period of time (billionths of a second) and it is exclusively absorbed by the melanocytes, leaving intact the surrounding healthy skin and tissue.
This ensures effective and safe treatment without any scars or other side effects.

The same method is also used for the treatment of congenital spots (Cafe au lait) and freckles.



Freckles are more common during childhood and puberty and less common in early adulthood.
They mainly appear on the face.
During the summer they are more intense and their number increases, whereas in winter they fade.
They are more common in children with red hair.
Q Switched Laser, 755nm and 532nm, is the preferred treatment method.


Cafe-au-lait spots

They occur at birth or shortly after that.

Their number increases up to the age of 20

They are present in certain syndromes, such as von Recklinghausen, Albright, Marfan.
They may relapse
Q Switched Laser, 755nm and 532nm, is the preferred treatment method.
