Industrial uses for this product include rust
removal and degreasing, so pure glycolic acid — generally sold in
concentrations of 70% or more — is extremely dangerous to exposed skin.
In fact, the government considers any product with a concentration of over 10% to be a hazardous material.
Most consumers know
glycolic acid not from its industrial uses, but from its cosmetic ones.
It is generally used as a natural skin exfoliant
and moisturizer, although there is much debate over its safety and
effectiveness. Some proponents suggest that products with a glycolic
acid concentrations of less than 10% are practically useless. The
problem is that many large-scale cosmetic producers will not increase
the acid levels for fear of liability and class action lawsuits. Some
smaller cosmetics companies with high-end clients do offer products with
at least a 10% acid concentration.
Glycolic acid
works as an exfoliating agent because of its high acidity but easy
solubility. When placed on the skin as part of an exfoliating cream
or gel, it goes under the damaged upper layers of skin and destroys the
'glue' which holds dead skin to the surface. As this dead skin is
chemically burned off, the other ingredients carry the individual flakes
away and a water rinse neutralizes the remaining acid. The result is a
much-smoother skin surface and a more youthful appearance. A secondary
benefit is the product's ability to draw moisturizers into the
newly-exfoliated skin surface. This is why cosmetic counters often sell
a complete system of skin care; the rest of the alpha-hydroxy line
contains moisturizers and neutralizers to counteract the corrosive
actions of glycolic acid.
Cosmetic exfoliants and
moisturizers containing glycolic acid may leave the user's skin
especially sensitive to the sun, so many skin care experts recommend
using a sunscreen after exfoliating with such products. Some customers seeking a more complete exfoliation
may opt for a chemical peel. In general, a chemical peel involves a
careful scrubbing of the skin followed by an application of a powerful AHA such as glycolic acid. Acid concentration levels in chemical peels can be as high as 50% or more. Even industrial suppliers of glycolic acid limit their concentration to 70%, so this is indeed a very powerful chemical process.
Quite often after a chemical peel, a patient's skin will look as if it were extremely
sunburned. Several days of recovery are often necessary for a complete
recovery from a chemical peel. Proponents of the process say that the
process may appear dangerous or unsightly, but the results are worth the
temporary discomfort.
Whether or not this
product is the miracle ingredient in a cosmetic Fountain of Youth, there
can be no doubt that it is effective when used correctly and in the
proper concentration level for an individual's exfoliating and
moisturizing needs. As with any other acid, proper attention must be
given to storage and access. Young children could experience severe
skin rashes or internal problems if the products are improperly applied
or ingested.In UK you can buy glycolic acid here www.kashtanpharma.co.uk
