    Diamonds for the skin

    16 Jun Diamonds for the skin



    Cosmetics Design

    For several years diamond-dust creams have been sold as an outrageously expensive treatment used by celebrities to ensure they walk the red carpet with a fabulous complexion. Now, Asian scientists say they have managed to produce diamonds inexpensively in their laboratory — making this luxury skin care fad potentially more affordable.


    The labels of creams containing diamond dust promise a smoother, younger skin from the first application, claiming that this gem has exfoliating properties that stimulate collagen production and help conceal wrinkles and blemishes. Marketing makes these texts not very different from those for other creams based on less exclusive ingredients. What is different, however, is the price of these exclusive creams, clearly aimed at the pockets of those who can afford the luxury. Read More

    Daily care of oily skin

    11 Feb Daily care of oily skin

    Our choice of cosmetics should be based on knowledge of our skin and its needs. Products exist that are specifically formulated for the care and protection of each skin type and each life stage. The daily care information and tips below are aimed at people who have very oily skin.


    We usually develop oily skin in adolescence due to age-related hormonal changes (with androgens playing a very important role), which lead to increased sebum secretion and, frequently, acne. Over time the excess oil production will slow down and the skin's appearance will improve. Sometimes the problem arises from the use of very comedogenic (favouring acne) cosmetics or products that are not suitable for oily skin. The prevalence of acne in adolescence is very high; some 70%-80% of teenagers affected, with little difference between boys and girls. Read More

    You have probably heard of the wonders of laser skin treatments and so may be asking if laser could help overcome some of the effects of ageing that start to become increasingly visible as you grow older. Be guided by a reputable dermatologist who will advise you regarding the treatment best suited for your skin type and condition — and also for your pocket.


    Laser advances are most especially being made at the cosmetic end of the spectrum, which means they are less invasive than traditional treatments like chemicals peels and dermabrasion. However, if you are considering some kind of laser or light-based treatment for your skin, it is extremely important that you consult a dermatologist or specialist centre. Be sure to ask about side effects, recovery times, number and frequency of treatments, any pre- and post-treatment skincare requirements. Read More

    Daily care of dry skin

    24 Dec Daily care of dry skin

    Understanding our skin and its needs should be the basis for our choice of cosmetics, so if you have very dry skin, you need to use products that are specifically formulated to treat dry skin and that also take into account your life stage. Below we provided some basic guidance for people with very dry skin.


    Dry skin has various causes, among them, genetics, aggressive drugs, overexposure to cold or sun, natural ageing, etc. But dryness is always the result of two factors: lack or excess loss of water (dehydration) and deficient sebum secretion by the sebaceous glands. A healthy, elastic, comfortable-feeling skin requires an optimal level of water in the stratum corneum. Certain components in dry skin are altered, but can be restored by suitable cosmetics. Hydration is the best way to maintain youthful skin and delay the onset of signs of ageing. Read More
