The Role of Antioxidants
In Dermtological &
Free radical oxidation is the basis of the aging
process because it causes permanent deterioration
of the skin cells and supports structure by decreasing elasticity and resiliency.
ANTIOXIDANTS play an important lifeline role in superior face and skin aging products. Antioxidants are natural substances made up of vitamins and minerals. They can
counter “free radicals” that damage DNA, lipids and proteins.
Damaged skin cells can speed up aging with wrinkles, dry skin,
dark circles under the eyes, dull skin, decrease elasticity and
Antioxidants most shown to combat skin problems are:
1. Açai oil
2. Alpha lipoic acid
3. Green and white tea
5. Vitamin C
6. Coenzyme Q10 (Co Q- 10)
Dermatological and cosmetic formulations contain fragrance,
fats and oils, which are all subject to auto-
oxidation by exposure to air, causing off
odor and chemical degradation.
Addition of antioxidants can be used
to preserve the formulations and increase the shelf life. Antioxidants can
be lipid-soluble, water-soluble or both.
Antioxidants neutralize free radi-
cals, which are produced by sunlight,
street air, auto pollution and other en-
vironmental factors, especially industrial
sources. Antioxidant based products are just as important as
sunscreen-containing products in battling aging and skin cancer.
They create a barrier on the skin to protect from the environmen-
tal and ultraviolet infrared rays.
Free radicals are the normal byproduct when cells are burning
glucose to create the energy, adenosine triphosphate (ATP), for
the body. Free radicals cause damage because they are missing
an electron. The loss of the electron makes the atom or molecule
electrically unstable. To regain stability, free radicals tend to steal
electrons from the surrounding substances in a chain reaction
that continues until stopped by an antioxidant. This process is
called free-radical oxidation chain reaction.
The Basis of Aging
Free radical oxidation is the basis of the aging process because it
causes permanent deterioration of the skin cells’ support structure by decreasing elasticity and resiliency.
The human body has its own natural mechanism of protection
from free radical induced damage. This protective capacity dimin-ishes with age and time of exposure where the magnitude of free
radicals formed overtakes the body’s natural ability to neutralize
Antioxidants in skin care products are capable of penetrating
into the deepest layer of the skin. Antioxidants enable living cells to
repair and renew. The end result is skin that looks and feels younger.
When formulating dermatological and cosmetic products it is
very important to consider several factors regulating
the impact of the product including, the ability
to penetrate the upper layer of
the skin, the concentration of
the ingredients required to
be effective and the time it
takes to show the signs of
improvement. Inclusion of
effective antioxidants is ex-
