Liposome delivery is a way of transporting a substance, such as a drug or a natural medicine, to a targeted area inside the body--usually the subcutaneous skin layer--without using needles or surgery, but rather through absorption into the skin. The reasons for the value of this are obvious. Needles are painful and require expertise to use. They also only deliver materials to a very specific site. Surgery is dangerous and invasive, not to mention expensive and very impractical.

In the case of skin care, in which substances beneficial to the skin need to be delivered to subcutaneous skin layers, liposome delivery is the perfect method. Liposomes are fatty acids that can encapsulate other ingredients and release them in a controlled way. Liposomes can be contained in liquids, creams, or gel; they can be rubbed directly into the skin, covering large areas of the body with no problem. Unlike needles, liposome delivery requires no skill in application and causes no pain to the recipient.

Are Liposomes Safe?

Liposomes are composed of lecithin and cholesterol, which are organic materials that naturally occur in the human body. For this reason, liposomes are an excellent delivery device because they can be safely absorbed into the human system. In other words, they're "biodegradable" to the human body, and may be taken without having to worry about any adverse effects, either immediately or in the long run.

Liposomes are being increasingly used in personal care and health products. For example, liposomes are contained in bodybuilding tinctures and lotions to deliver growth hormones to the muscles, joints and bones. In addition, advanced skin care products, such as anti-aging treatments and cellulite creams, deliver active ingredients to the subcutaneous layer of the skin to build up collagen, dehydrate fat cells, and smooth out uneven skin surfaces.
