Do you know what is
the most commonly discussed skin condition in my Jeddah based dermatology
practice? — Skin Pigmentation. Doctor why is my
skin marred with dark patches and spots? Why my skin tone is not clear? Am I
suffering from melasma? Do I have pigmented skin type? What is pigmented skin
type? And this list of complexion concerns doesn’t end with the face only they creep downwards involving different areas of body too. Pigmentation related
skin concerns like: melasma, uneven skin tone, dark elbows and knees are hot
concerns among Middle Eastern and Asian skin. Horror tales speaking about misuse
and abuse of legit and non-legit bleaching and skin whitening agents are too
familiar across these regions, yet more chapters are continuously added to this
book of cautionary tales.
I thought it’s be
nice to get you acquainted with some of the newer and relatively safer ingredients,
including some derived from plants, which are now being used in topical
treatments for hyperpigmentation. Next time you are out shopping for a new skin
blending and bleaching product look for these names in the ingredients list:
Soy
- Derived from the soybean plant, it is one of the most commonly used skin-lightening ingredients in moisturizers and a combination of products and cosmeceuticals.
- It works by inhibiting the transfer of melanosomes (small “packages” of melanin) into the top layer of the skin, which causes skin darkening.
- Studies have shown its effectiveness as a skin lightening ingredient in cosmeceuticals and its ability to suppress additional pigment from coming to the surface of the skin.
Niacinamide
- It is a form of vitamin B3 that acts like soy by inhibiting the transfer of melanosomes into the skin’s upper layer.
- It is used in many cosmeceuticals for its skin lightening effects and its potential to prevent additional pigment from coming to the surface of the skin.
Ellagic Acid
- It is a natural substance derived from strawberries, cherries, and pomegranates.
- It works as an antioxidant and also inhibits an enzyme needed for melanin production.
- Studies show it is more effective at skin lightening than kojic acid or arbutin, which are both discussed below.
Lignin Peroxide
- It is an enzyme derived from a fungus that can break down melanin in the skin.
- Lignin is found in wood pulp and when it breaks down, it can lighten the wood pulp. This is how wood pulp is whitened for use in paper and how lignin was discovered as a skin-lightening agent.
- Currently it is available in an over-the-counter product range called Elure.
- Studies have not been completed, but anecdotal reports have highlighted its skin-lightening properties.
In addition,
studies have shown that these four ingredients pose little or no allergy risk,
so they might be more tolerable to consumers who are allergic to other natural
lightening agents. If an allergic reaction occurs, you should discontinue use
and see a certified dermatologist for treatment.
The following three
ingredients have also shown promise as skin lighteners, but they can cause an
allergic reaction in some individuals:
Arbutin
- A natural derivative of hydroquinone derived from plants, including bearberry, blueberry, and cranberry.
- It is usually available in combination with other skin-lightening agents in over-the-counter cosmeceuticals.
- Some cosmetic products available at high-end department stores contain 3% concentrations, which studies show can significantly lighten the skin.
Kojic Acid
- It is an antioxidant derived from a fungus rather than a plant. It works by breaking down melanin in the skin and preventing its production in the skin.
- Found in cosmecuticals in 1% to 4% concentrations either combined with other skin-lightening agents or by itself.
- Clinical studies show improvement in skin lightening.
Licorice
- There are a number of different licorice extracts derived from licorice root.
- Liquirtin is available over the counter and has been shown to lighten skin.
DERMATOLOGIST RECOMMENDED EXPERT ADVICE:
Those affected by
hyperpigmentation who would like to use a topical treatment to lighten their
skin should consult a certified dermatologist who can help, separate fact from
fiction in terms of product claims. It’s important to remember that even
topical treatments backed by science do not work overnight because it takes
time and consistent use to produce a noticeable improvement. You should also be
cautious about ordering skin-lightening products via the Internet, because the
country of origin for the active ingredients might be unknown, raising
questions as to the purity or effectiveness of these ingredients, as well as
the product’s overall quality.
