What Are Liposomes In Skin Care?
If you have heard about liposomes in skin care and you are wondering whether they are the next big thing in anti-aging skin care, in this article you will find all about what liposomes are used for in skin care products including what they are made of and their function.
First, let me ask you a question. Have you ever thought of how those active ingredients make your skin cream work and how these ingredients travel from the upper layer of the skin to the deeper layers?
Actually, they don’t do it on their own but they need some type of a ´vehicle´ which is no other than liposomes.
What Are Liposomes Used For?
The effectiveness of the skin products we are using does not depend solely on the number of active ingredients they contain.
In order for those ingredients to be truly effective, they need to reach the skin layer which they are meant to reach and offer maximum results.
In the world of cosmetics, this is called ‘bioavailability of the active ingredients.’
Knowing where these components need to go is not enough, they also need the right ´vehicle´ to transfer them there.
In order to reach those skin cells, the cosmetic industry is using liposomes, the most well-known system of transferring active ingredients to those key areas.
History Of Liposomes
The first person who saw liposomes in a microscope and described them was Dr. Bangham, a British hematologist.
His research opened the way for the development of a new innovative system of transferring active substances in the human body with the aim of curing serious diseases.
20 years after this discovery, liposomes were used in cosmetic formulations to transfer moisturizing, nourishing and anti-aging ingredients to those areas of the skin where they are more needed.
Especially during the latest years, the cosmetic industry with the help of nanotechnology has developed nanoliposomes.
Nanoliposomes are 20 times smaller in size than normal liposomes. They penetrate deeper into the skin and release active ingredients gradually and for a longer time.
Thus, the formulation of cosmetic creams is reinforced without altering its texture and becoming thickish and greasy.
What Is The Function Of Liposomes In Skin Care Products?
As we have already mentioned, liposomes are not ingredients but they are active lipid carriers.
Due to their unique molecular structure, these microscopic sphere shaped vesicles can hold and transfer nourishing cosmetic ingredients as well as pharmaceutical substances.
Vitamins that have a high molecular weight such as vitamin E as well as natural oils, moisturizing and anti-aging ingredients are integrated into the liposomes.
Due to the similarity of liposomes to lipids, which make up the membrane of the cells, liposomes trick the barrier of the stratum corneum (upper layer of the skin) and facilitate their penetration, absorption and release into those areas where our skin mostly needs these ingredients.
What Are Liposomes Made Of?
Liposomes are made of lipids and water which improve the texture of the skin, making it smoother and softer.
By penetrating into the deeper layers of the skin, they become one with the cell membranes. They transfer the ingredients they are carrying and boost moisture in the skin, delaying the appearance of skin aging signs.
To conclude, what makes liposomes in skin care even more interesting is the fact that although they are not considered to be ingredients, in the strict sense of the word, they offer important benefits to our skin.
