KOJIC ACID: TREATMENT FOR DARK SPOTS, PIGMENTATION, ACNE.
KOJIC ACID - TREATMENT FOR DARK SPOTS,
PIGMENTATION,ACNE
·
- If you ever get curious about the active ingredients in skin lightening creams, you will find that Kojic acid is commonly used as a skin whitening or depigmentating agent in concentrations of 1%
- It is commonly used in leave-on creams, anti-aging creams and lotions, around-eye creams, facial cleansers, which are generally applied to the face.
- Can also be used in body moisturizers and sunscreens.
- Because so many people are suffering from melasma, I figured I would offer you more information on an ingredient that’s known to treat it more effectively than hydroquinone.
- We’ll also understand the Kojic Acid structure, as well as the relation between Kojic Acid and melasma.
KOJIC ACID STRUCTURE
·
Kojic acid is a
by-product in the fermentation process of malting rice,
·
Inhibits the
conversion of tyrosine to melanin.
KOJIC ACID IN SKIN CARE PRODUCTS
·
Kojic acid in skin care products has the main
purpose to treat hyperpigmentation, which occurs when areas of the skin develop too much melanin.
·
The
body naturally produces a pigment known as melanin through specialized cells known as melanocytes.
·
In people with fair skin, only small amounts of melanin are processed
by melanocytes, while larger amount of the pigment are made by the cells of
those with dark complexions.
·
The
production of melanin is increased in response to environmental or internal
conditions such as: sun exposure (causing the skin to tan), inflammations (common among acne sufferers) and pregnancy.
·
Repeated exposure to the sun can result in a permanent increase in
melanin production in spots on the skin, causing small freckles and larger sun
or age spots to form. And here is where the Kojic acid comes in handy.
KOJIC
ACID AND MELASMA
·
When
kojic acid is applied to the skin in concentrated amounts, the chemicals in the
ingredient work on the melanocytes, interfering with the production of melanin.
·
In
addition to its skin-lightening abilities, kojic acid is classified as an antioxidant. This class of nutrients has the ability
to counteract the effects of particles in the air called free
radicals, which have
the potential to cause oxidative damage to the skin cells.
·
By
limiting the effects of free radicals, kojic acid helps to prevent
the formation of signs of aging that occur when the cells that produce the skin’s vital
structural proteins become damaged.
