Answer

Treatment of Discoloration From Acne

Discoloration from acne (red, purple, brown, black, and white) is less permanent and easier to treat than acne scarring. However, it is also much more common. Both topical medications and surgical methods are employed.

Post inflammatory hyperpigmentation and acne
A post inflammatory hyperpigmentation macule often is the remnant of an inflamed acne lesion. PIH macules can follow relatively minor pimples and papules, in addition to more serious lesions. However, the more inflamed a breakout, the larger and darker the PIH macule tends to be. Picking or popping a pimple increases the chance of developing post inflammatory hyperpigmentation.

You can identify post inflammatory hyperpigmentation by carefully examining the skin. PIH macules can be a range of colors, however, the skin will not be pitted or depressed. It may look like a discolored freckle on the skin, or it may present as a larger, dark discoloration of the skin. PIH macules may look shiny, or like "new skin."

Treating PIH
Most acne sufferers are relieved to learn that post inflammatory hyperpigmentation is not scarring. PIH will fade away over time, even without treatment. It can take three to 24 months for PIH to fully fade, although in some cases it may take longer. The length of time it takes for PIH to fade depends on how dark the PIH macule is compared to your skin tone. The bigger the contrast between the macule and your natural skin tone, the longer it will take to fade.

There are treatment options available to help fade post inflammatory hyperpigmentation more quickly. However, your acne should be under control before beginning any treatment for PIH. Otherwise, each new pimple could cause another PIH macule, reducing the effectiveness of treatment.

Whatever treatment option you choose, understand that improvement will take time. Think in terms of months rather than weeks. Also, many dermatologist recommend using a broad-spectrum sunscreen daily. The sun may darken the discolorations and increase fading time.

Over-the-Counter Treatments
Mild cases of post inflammatory hyperpigmentation may respond well to over-the-counter products. A variety of topical treatments have been used to treat epidermal PIH, with varying degrees of success. These agents include hydroquinone, tretinoin cream, corticosteroids, glycolic acid (GA), and azelaic acid. Lightening of hyperpigmented areas may be achieved with one of the previously named topical agents; however, a combination of topical creams and gels, chemical peels, and sunscreens may be necessary for significant improvement.

Pigmented makeup creams have also been successfully used to camouflage hyperpigmented skin to a hue similar to that of the surrounding unaffected skin.

Hydroquinone
Hydroquinone is a widely used treatment for post inflammatory hyperpigmentation. It is available over-the-counter at 1% to 2% strength, and in 3% to 4% prescription creams. Hydroquinone works by blocking the enzyme responsible for melanin production, thereby lightening the skin.

Hydroquinone creams often contain additional lightening ingredients, such as kojic acid, glycolic acid, tretinoin and other retinoids, or vitamin C. These combination creams can give you better results than using hydroquinone alone.

Hydroquinone creams should be carefully applied to darkened areas only, to prevent the unwanted lightening of your natural skin color. Hydroquinone may cause irritation in sensitive individuals. It's worth talking to your doctor before beginning hydroquinone treatment.

Topical Retinoids
Retinoids, such as tretinoin and tazarotene, are often prescribed to acne patients. Retinoids help clear acne by speeding up cell turnover rates. It is this rapid exfoliation that can also help clear PIH. Retinoid creams include Retin-A, Tazorac, and Differin. The fact that they lessen post inflammatory hyperpigmentation as they treat acne breakouts is an added benefit for many people.

Obvious results may not be apparent for several weeks to several months after beginning treatment. Topical retinoids may cause excessive dryness, redness, and/or irritation, which may in turn increase hyperpigmentation. Let your doctor know right if you experience any of these side effects.

Glycolic Acid
Glycolic acid is an alpha hydroxy acid found in many skin care products. It effectively exfoliates the skin, helping to lighten post inflammatory hyperpigmentation. Available in cleansers, creams, and gels, glycolic acid not only helps improve postinflammatory hyperpigmentation, but also leaves your skin smooth and soft.

Cleansers, gels, pads, and lotions containing glycolic acid are available over-the-counter. Higher concentrations are available with a prescription only. As with all products, improvement may not be seen for several months. Monitor your skin for irritation, and inform your doctor if it occurs.

People with PIH should use sunscreen on a daily basis to prevent any further darkening of lesions.

Special Concerns

Patients should never be treated with monobenzyl ether of hydroquinone because of the risk of developing disfiguring depigmented patches of skin either at the application site or at distal cutaneous sites.
Prognosis

PIH tends to fade with time and therapy, as previously discussed.
Remnants of epidermal hyperpigmentation may persist for indefinite periods, typically 6-12 months, after the initial inflammatory process resolves.
Dermal PIH may even persist for years.
Natural solution

However, there is a natural alternative if you dont like the idea of using artificial treatments.

BIOSKINREJUVENATION cream is a natural peeling option because it's not a chemical man made drug or a pharmaceutical product. It is a natural cosmetic product made with the natural serum secreted by a land snail from the species knoiwn as Helix Aspersa Müller. This creature produces it to quickly repair its own skin and shell whenever it is damaged. It is a viscose liquid that is made into an odorless white cream.
