Concepts of Natural cosmetics

Imagine that the structure of the skin is a set of bricks and cement. The cells of the stratum corneum would be bricks and intercellular material that holds cells together would be the cement. As aging, skin cells lose their shape and the intercellular material loses consistency, distance between cells increases, the skin loses tone and firmness and lines that appear show the dryness of the skin.

The A.H.A. works to restore the skin a youthful appearance. However, only perform the restoration work. The ceramides act as molecular cement, reinforcing the new, smaller layers of cells, to remain united.

Ceramides strengthen moisture barrier and enhance its status. This barrier allows the stronger A.H.A. work more effectively.

Natural component of skin, it has a great capacity to retain water, which gives moisturizing qualities, smooth and firming. It also is used in its composition many creams.

Its concentration decreases with age. It is the regulator of intercellular space.

Collagen is a protein found in the dermis, has the goal to be the layer supporting the skin. The space between collagen fibers contain a protein called elastin which helps the skin quickly returns to its original position after being stretched.

Also there is water between the collagen fibers which serves to lubricate the collagen network of support to keep it malleable.

Over time, collagen fibers become loose, elastin loses its elasticity and the water evaporates, and the wrinkles are accentuated. Any repeated facial movement contributes to this tension. The sun also affects the collagen, causing loss of moisture.

As we age our bones, muscles and adipose tissue gradually shrink, the skin is stretched, it loosens and with these changes are the bags and wrinkles. For these properties, collagen is used between the ingredients of creams, and injectable form to supplement the collagen of the skin.

These cosmetics are not usually recommended in the young.

When applying a moisture cream with collagen in the skin, it tends to stay there.

Some studies indicate that the incorporation of AA vitamins help prevent the formation of wrinkles, promotes healing of skin, and reduces scar formation, making these products, key components in plastic surgery and the care and preliminary post-surgery. These vitamins help to defend skin against free radicals using teamwork: fat-soluble vitamins such as vitamin A and E protect the cell membrane and its structure fotolípida, while water-soluble vitamins protect the interior of the cell and DNA.
