What are moles?

Moles are small formations colored in various shades of brown present in the skin. Most often are benign but which are the signs that should alarm us in terms of their appearance to go to the doctor?

The rule is simple: ABCDE

Any asymmetric lesion (A – asimetry), with irregular borders (B – borders), with more than three shades of color on the surface (C – color), large (D – diameter), which increase in size (E – evolution), it must refer you to a doctor. This, with dermatoscopy – a special monitor for moles, will indicate you the steps. It can be monitored at 6 months to track injury or they may require surgical excision and sent the piece for histopathological examination.

How to prevent the appearance of moles?

The mole’s appearance is largely genetically programmed. The only factor on which we can intervene is the amount of UV reaching the skin. This does not mean you have to don’t sit in the sun, but only to follow certain rules:

- not exposed to the sun between 10.30-17.00
- during the summer use a photoprotection cream proper for your skin
- if you stay at the seaside repeat applying the cream every 2 hours or after entering the water
- use only quality products which are tested for their effectiveness.


The first time a sun screen was used in 1928 in the United States. Since then the cosmetic industry has experienced a continuous development.

What you should know when buying a photoprotection cream:

Solar filters can be divided into two categories depending on the wavelength of absorbed solar radiation: UVA filters and UVB filters. It is important that a cream contain both filters.

Solar screens prevent both immediate reactions (sunburn) and late effects – photoaging or carcinogenesis (skin cancers).

There are about 16 agents with the role of sunscreen use.

Solar screens act as a barrier to sunlight by a chemical mechanism or by a physical one. There are only two physical filters titanium dioxide and zinc oxide. Physical screens are well tolerated and do not give allergic reactions, they are not absorbed in the body. The mechanism is very simple: to reflect sunlight.

At present the majority of people apply an insufficient amount of cream. Photoprotection is effective in 2mg/cm2. The cream is applied 20 minutes before exposure and repeat every 2-3 hours. As for the children under 6 months clothes are the best protection, much better than photoprotection creams. Applying a photoprotection screen can affect the synthesis of vitamin D (some studies). Consumption of fruit and vegetables, through the antioxidant vitamins: vitamin C, E, beta carotene carrot 120-180 mg/day, decreases sensitivity.

Of foods and drinks effective in photoprotection list: green tea, red wine, cucumber, tomatoes, broccoli, grapes, citrus, blueberry, olive oil.
