The most popular technique currently being used to remove skin tattoos is laser, whose therapeutic and aesthetic results surpass those of the chemical and surgical solutions of before. But tattoo removal is no trivial matter, as it requires both patience and money. Today I interview Dr. José Manuel Miralles, a dermatologist and expert in laser medicine.
How does laser remove tattoos? Nowadays we use Q-switched technology, which is laser that emits high-energy but extremely short-duration pulses. It photoacoustically or mechanically breaks up the pigment particles, and any pigment that remains is then removed by immune system cells. Previous lasers destroyed the pigment thermally and were not as effective. Read more
Artificial tanning beds pose an additional risk for the health of our skin and lead to the development of melanoma. However, millions of people throughout the world continue to use them, despite the warnings of doctors and health authorities. A new scientific study confirms the seriousness of the problem.
This blog has frequently highlighted the health risks posed by artificial ultraviolet (UV) light tanning, mainly because they represent a high risk factor for developing melanoma, the most aggressive of the skin cancers. We are not alone: medical associations – pointing to irrefutable scientific studies – have been warning that this practice is the direct cause of the dramatic increase in skin cancers witnessed in recent decades, especially in white women.

Our skin contains natural ingredients that protect it and keep it hydrated. These substances form the outermost layer of the skin (the stratum corneum). When the functioning of this outer shell is disrupted, our skin loses water. Dry skin is a common problem that is tricky to resolve. But why does our skin become dry?
We wash too often, use highly alkaline soaps and expose ourselves to excessively dry air from heating and cooling devices. Often we lead a lifestyle that does not allow the skin to follow its natural regeneration cycles. We know that hydrated skin is essential for the epidermis, most especially its outer protective layer, to retain its structure and function properly. When its barrier function is altered, the skin loses water and shrivels like a leaf, which is when we notice discomfort and even itchiness. In short, the skin dries out. Read more
Too much sun is the main cause of skin ageing. It also leads to the development of melanoma, the most malignant form of skin cancer. A recent study links aspirin use to a lower incidence of melanoma in women.
For decades, aspirin (acetylsalicylic acid) has been used to lower the risk of heart disease and of bowel cancer, with millions of people around the world taking a small dose daily. The findings of a recent study published in Cancer would seem to attribute new benefits to the modest and traditional aspirin. The research was conducted in the USA over a period of 12 years on almost 60 000 postmenopausal women aged between 50 and 79 years. The results show that taking aspirin reduces the likelihood of melanoma – the most serious of the skin cancers – by 21%. No doubt this is good news, but further research is needed to confirm that these results are generally applicable. Meanwhile, just remember that the most important thing is to protect our skin from the sun’s ultraviolet rays. With or without aspirin
