    Personalized cosmetics?

    30 Nov Personalized cosmetics?

    Itai??i??s a good marketing idea that also appears to be successful. Products labelled with our name and designed to suit the personal features of our skin, after one or several laboratory tests ai??i?? photonics technology used to determine what our skin needs at all times. The cosmetics of the future will likely be personalized, but for now they are difficult to produce and expensive.


    A recent market research study in the UK cosmetics market found that, before buying a typical branded product, 47% of adults would be willing to go to a laboratory to obtain a cosmetic product that was specifically designed for their skin. This kind of personalized cosmetic would take into account genetics, allergies, nutrition, climate and sun exposure habits, among other factors. Read More

    Preservatives in cosmetics: the good, the bad and the ugly?

    26 Nov Preservatives in cosmetics: the good, the bad and the ugly?

    Our skin comes into daily contact with some kind of cosmetic preservative. Soaps, gels, creams, foams, lotions, perfumes ai??i??virtually all cosmetic products require at least one preservative agent to make sure they get to consumers in perfect condition. Some preservatives may be harmful, however, and health authorities legislate continuously for the good of our skin and our overall health.


    The perfect preservative is one whose antimicrobial action inhibits all contaminating microorganisms (bacteria, moulds and yeasts) from cosmetic products. It must also be stable and inert towards other ingredients in the formula and, above all, it must have a profile that allows for safe use in the intended product at the intended concentration. It is often difficult for a single biocidal ingredient to satisfy all these requirements. Often people focus on the most natural ingredients, assuming them to be least toxic. Read More

It may increase the risk of skin cancer, even though we may have been burned ai??i?? as children ai??i?? before we were aware of the consequences. We have been warned time and again, but we still see skins red as tomatoes from the sun.


    Thatai??i??s why some organizations continue to emphasize informing the consumer. This Cancer Research (UK) video explains what happens to cells when the sun damages them and the difference with other burns caused by hot objects. The other burns heal, but burns from the sun can have dramatic consequences many years later. Contact burns merely destroy some skin cells, nothing more. Sunburn also destroys cells, but it also alters the DNA of surviving cells and this can lead to the development of cancer. A simple but enlightening reason not to forget to protect yourself from the sun. Read More

    Flying: it wreaks havoc on the skin

    16 Nov Flying: it wreaks havoc on the skin

    When you fly, pressurized air in the cabin sucks out the moisture in your skin, leaving it feeling dry and looking dull and lacklustre. The haggard complexion on landing is directly proportional to the length of the flight. What can we do to protect our skin so that we donai??i??t look drained when we land?


    Cabins are pressurized using low-humidity conditioned air to create a safe and comfortable environment for passengers and crew flying at high altitudes and protect them from the risk of physiological problems caused by low outside air pressure. But flying does affect the skin. The main repercussions for the skin on the face and the body arise from dehydration: dry skin, cracked lips and dry throat, nose, eyes and hands. The body also responds to jet lag and fatigue by releasing the stress hormone cortisol, which impairs the skin's barrier function and causes redness, blotchiness and breakouts. Read More
