    Acne is probably the most common skin problem, affecting 75% of people at some point in their lives. For many young people it is an aesthetic and self-esteem issue of the first order. A new patent based on natural substances could prove to be a very effective treatment.

     

    Acne is treated using various kinds of active ingredients, ranging from chemicals to antibiotics and including isotretinoin, the most effective treatment, although it must be taken under medical supervision. Scientists at the University of Granada have created a formula that is applied topically, does not meet with bacterial resistance and has no side effects. Its main ingredient is a cyclic protein of 70 amino acids called AS-48. The formula is active against various pathogenic bacteria of the skin, including the Propionibacterium acnes bacterium responsible for acne. The scientists hope that their formula, which contains only natural substances with antibacterial activity, will soon become a basic cosmetic and pharmaceutical ingredient for the treatment and prevention of acne.

    Laser tattoo removal

    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.

    Winning the battle against skin dehydration

    30 Sep Winning the battle against skin dehydration

    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
