The meaning of this word is derived from PRO meaning for or in favour of and BIOTIC meaning life.
Probiotics are generally associated with the good bacteria in the digestive tract, but what works internally does not necessarily work topically.
Probiotics are used in cosmetics as a bioactive ingredient to keep the skin healthy.
Skin is a barrier against the environment which harbors invading pathogens.
The skin's epidermal layer plays an enormous role in protecting the underlying layers. In addition good bacteria and the secretions of the sebaceous glands help to maintain the acid mantle of the skin, preventing micro-organism from breeding, which have a preference for an alkaline environment. Thus the pH [potential hydrogen] of the acid mantle is kept between 4.5 and 5.5 to 6.00 neutralizing any external contaminants.
The skin ages as a result of inhibited cell renewal. For example this occurs every 20 days in young adults, every 30 days in middle aged adults and declines in old age.
Therefore it is essential, from an early age, to care for the skin on a regular basis, relying not only on the application of cosmetics, but to live healthily and have good nutrition.
Exterior skin food can maximize the skin's vitality and Probiotic technology has been proven to reduce cellular damage up to 50% and activate cell renewal up to 70%.
This expertise is an enormous boost to the laboratories developing anti-ageing preparations.
Now the discussion arises as to what benefits the skin derives from the inclusions of probiotics. They are a good source of amino acid proteins, vitamins, trace minerals and anti-oxidants and supply nourishment, hydration and protection of the vital collagen fibres.
The ingredients put to use are variable, depending on the end result required and some of these include the following:
- Fats and oils derived from grains like wheat germ oil, high in vitamin E and a stable, reliable anti-oxidant
- Shea butter derived from nuts
- The soya bean which yields lecithin
- Jojoba, a humectant, which guards against skin's dehydration
- Glycerine, having a hydroscopic action, meaning that it can draw moisture from the atmosphere
- Beeswax with its thick texture, most useful in balms and pomades
- Honey an excellent anti-bacterial agent which has natural preservative qualities
- Lactic acid, extracted from grains, exfoliates dead surface epidermal cells, by naturally breaking down the substance that keeps cells intact
- Aroma oils, interestingly, a combination of four cold-pressed oils, namely sweet almond, apricot kernels high in vit A, macadamia and safflower
Unfortunately many skin formulations deliver a “smorgasbord” of chemical additives which can lead to allergies and skin irritations and offer little of what is promised.
One should train oneself to be a discriminating consumer and not accept anything which is inferior. Cheap may be good for the pocket, but choosing cosmetics which include probiotics, far outweighs the "more for less" mentality.
Ultimately, what is pure is best and will deliver the expected results!
