    Fake tanning products are the perfect solution for people who like to have a bronzed skin all year round, yet want to reduce the negative effects of solar radiation and prevent skin cancer. Here we consider the advantages and disadvantages.

     

    Current sunless tanning products have come a long way since the first such products were launched on the market in the 1960s. Such products were not entirely successful, however, due to the uneven and orangeish tan they produced. Current tanning products not only give a more natural, long-lasting colour, they cater for all tastes and skin types. They come in different forms (cream, gel, spray, wipe, etc) and often offer additional benefits (as moisturizers, sunscreens, anti-wrinkle products, etc). Read More

    Fascinating alum crystal

    Alum crystal, used by ancient civilizations, has come back into fashion with the rise of natural cosmetics. It has many properties, including as a body deodorant. How does it benefit the skin? Is the aluminium it contains hazardous?

     

    Alum crystal is a naturally occurring sweet-tasting mineral that looks like translucent glass. It is usually composed of an aluminium sulfate and a sulfate from another metal. The most commercially exploited alum is the hydrated form of potassium aluminium sulfate (potassium alum), which comes from a volcanic igneous rock called aluminiferous trachyte; it can also be manufactured industrially, however.

    Retinol (vitamin A) is one of the most common ingredients in anti-ageing cosmetic creams, lotions and oils. Although the most effective results are achieved by applying retinol to the skin, it is also supplied in the form of vitamin supplements. Is it as effective as they say? What don’t we know about this component?

     

    In theory, it’s all benefits: retinol helps against wrinkles and premature signs of ageing, sun or age spots (photoageing), acne and pigmentation problems, and also improves the texture of the skin. Its antioxidant capability fights free radicals in our body and protects against cell damage. It also stimulates the production of collagen and elastin, which give the skin strength and flexibility.

    Botox is the treatment of choice for removing wrinkles and giving the skin a youthful appearance. Its use was known to Hollywood stars, but since approval in 2002, Botox use has reached addictive levels among the general public. It is “inexpensive”, effective and painless and requires minimal aftercare. Is it the perfect treatment?

     

    Last July the case of an illegal clinic came to light in Barcelona. The owner, who had no licence, was giving botox injections without any health guarantees and in unhygienic conditions. There was a similar case in Florida (USA) in 2004; four people showed symptoms of poisoning after they were treated with a substitute botox product that was cheaper but not authorized for human use.
