I. What is Alpha-Lipoic Acid (ALA)?
Also
known as Thioctic Acid, it occurs naturally in plants and animals. It
functions as fat soluble as well as water soluble antioxidant that is
why it is called "the universal antioxidant". Being both water
and oil soluble, ALA can access all parts of a living cell. Alpha Lipoic
Acid has the ability to regenerate itself and other antioxidants like
vitamin C and E so that they would be able to remove more free radicals
from our bodies. ALA also increases the production of glutathione which
is the most abundant natural antioxidant in the body.
II.
How does topical Alpha-Lipoic Acid (ALA) work on acne?
The
primary use of alpha-lipoic acid in acne is the reduction and healing
of acne scars. Alpha-Lipoic acid activates a certain activator protein
which stimulates the production of enzyme that removes the damaged collagen
in acne scars. Alpha lipoic acid also has a moderate anti-inflammatory
effect which soothes skin irritation caused by acne. It is also reported
to decrease the appearance of enlarged pores, decrease fine lines/wrinkles
and the improvement of skin tone/skin texture.
"Alpha
lipoic acid also helps aging cells increase their energy production.
This enhances their ability to repair cellular damage and expel cellular
waste products. Because of this action, alpha lipoic acid, as a 1% lotion,
has been used as a skin treatment for aged skin".

Advantages
- Natural
and have very few side effects.
Disadvantages
- Few
peer reviewed studies. Most of the studies and patents involving the
use and efficacy of topical alpha-lipoic acid has been published by
Nicholas Perricone. Dr. Perricone's work have been criticized as having
questionable, unverifiable, and erroneous statements at www.quackwatch.org

Efficacy
- A
method for reducing and preventing acneiform scars and reducing pore
size comprising topically applying to affected skin areas a composition
containing lipoic acid or a lipoic acid derivative in a dermatologically
acceptable carrier.

- Scar
tissue is reduced or inhibited by application of a composition containing
lipoic acid and/or a lipoic acid derivative such as dihydrolipoic acid,
a lipoic or dihydrolipoic acid ester, a lipoic or dihydrolipoic acid
amide, a lipoic or dihydrolipoic acid salt, and mixtures of any of these

using lipoic acid ,Nicholas V. Perricone)
- Alpha-lipoic
acid (LA) or the reduced form dihydrolipoate (DHLA) is a potent scavenger
with anti-inflammatory properties. Previous uncontrolled studies with
topical treatment with 5% LA-containing creams indicate a beneficial
effect on photoageing skin.It is indicated that 12 weeks of treatment
with a cream containing 5% LA improves clinical characteristics related
to photoageing of facial skin.
