¿They are pigmented lesions of the skin or age spots


Part of the process of skin aging is manifested by the appearance of pigmented skin lesions called age spots ( LS ). The age spots are hyperpigmented macules with irregular shapes that can appear in any region of the cutaneous surface. Predominate in sun-exposed areas ( face, hands and forearms ). Affect both men and women, most frequently from 50 years.

¿, can be treated with laser pigmented lesions


The Q -switched lasers ( Q -switched, QS ) enable accurate, fast and effective treatment for pigmented lesions of the skin, with few side effects. There are different useful for the treatment of senile lentigines lasers, we have experience with the QS alexandrite laser. Compare to the conventional treatment with cryotherapy or trichloroacetic acid peels, QS alexandrite laser provides more efficacy and fewer side effects in the treatment of pigmented skin lesions.

The QS alexandrite laser produces 50-100 ns pulses at 755 nm ( red light). It is effective for the treatment of epidermal pigmented lesions, dermal shallow tattoos and blue, black, green, brown and violet. According to the theory of selective photothermolysis a specified destruction of subcellular organelles, such as melanosomes and tattoo particles by photoacoustic effect ( fragmentation ) and photothermal occurs.

¿treatment has side effects


Side effects of treatment of pigmented skin lesions are: itching immediately ( refer to the few minutes), transient edema (especially if it is the eyelid region ), appearance of brownish or purpuric macules disappear after a few 7- 10 days and residual erythema disappears in 4-6 weeks. Rarely can seem hyper or postinflammatory hypopigmentation, usually appear in people tanned and / or phototypes III and IV. The risk of post-inflammatory hypopigmentation is less with the QS alexandrite laser than with other types of lasers, such as ruby QS. It is more difficult to treat than hyperpigmentation and can be permanent. The development of secondary infection is outstanding, however, once treatment is completed using a topical antibiotic cream is recommended. Occasionally, when the LS is very dark, repeat the treatment after 1 month to get an optimal result.

Take extra care in tanned patients;whenever an initial test can be conducted and a depigmenting cream topical treatment were used before.
