Ingredients - nanoparticles
So small and subtle - nanoparticles from solid to liquid
The ingredients of nanodispersions can partly replace pharmaceutical active agents - often with the same efficiency.1 Hence they are ideal base substances for cosmeceuticals.2
Phospholipids - the all-rounders
What does an element like phosphorus that rather is associated with the match industry have to do with skin and cosmetics? As a matter of fact, most of the processes in which the substance is involved take place without becoming aware of them. It is not exaggerating to say that phosphorus and phospholipids are absolutely vital for life.
Biodegradable lamellar systems in skin care, skin protection and dermatology
ABSTRACT: The following review comprises background, literature and applications of biodegradable lamellar systems, their characteristics and limitations. The article is focussed on phosphatidylcholine containing preparations like liposomes, nanodispersions and derma membrane structure.
Piggyback - an overview on transport systems
Speaking of transport systems for cosmetic active agents, we automatically think of tiny filled spherical bodies that wriggle their way through the gaps between the corneocytes and then empty their load in the deeper layer of the epidermis. That is a good story though, but unfortunately not a true one. The following article will deal with the actual facts.
Without carriers only modest effects - Functions and effects of carriers in cosmetic products
When we talk about carriers in cosmetic products we need to distinguish between particular chemically defined substances and physical carrier bodies. In conclusion, both alternatives have the same effects: combined with active agents they increase the bioavailability. An enhanced bioavailability requires in-depth knowledge on the physiological processes in the skin and strictly contrasts with the idea of "a lot helps a lot!"
Nanoparticles - sizing up skin care
I recently read an interesting article, passed to me by my Australian colleagues. It's a long way from Germany to Australia but the issues raised in the article "I'm as Mad as Hell....." by Danné, published in the Nov/Dec 2010 issue of Professional Beauty, resonated with me so strongly I felt obliged to put pen to paper.
Nanoparticles in cosmetic products - good or bad?
New developments create anxieties and raise questions. First and foremost because it lacks information and experience. Frequently hearsay is the only source of information available. Nanoparticles are not the same kind of quantum leap as the first steam locomotives were, though. The following article will bring some light into the darkness around the small particles.
Precious load - transport of active agents
Within the field of skin care and dermatology active agents play the most important role. Appropriate transport systems ensure that active agents are transported to the areas where they are really needed.
Active agents: liposomes, nanoparticles & co
Life can only exist in an atmosphere which provides protection against outside influences. Thus, monocellular living organisms are protected by cell membranes whereas multicellular organisms are provided with an exterior skin whose outermost layer, the epidermis also has a membrane-like structure which together with its specific composition serves as a model for cosmetic and dermatic products.
Strong effects - phospholipids in cosmetics
Phospholipids are indispensable for the live organism and play an essential role for both health and nutrition due to a great variety of different functions. They also prove to be perfect base substances for cosmetic products.
Encapsulated substances - the capacity of carrier systems
Liposomes and nanoparticles have a high affinity to the horny layer of the skin due to their composition. With the help of these carrier systems water and oil soluble substances can easier penetrate the skin.
