Lichen planus can leave behind discoloration on the skin even after the active lesions have healed. These areas of altered pigmentation are not a sign of ongoing disease, but rather a cosmetic concern for many individuals. This article explores various home remedies that may help in fading these marks.
What Lichen Planus Marks Are
The discolored areas that remain after lichen planus lesions resolve are a form of post-inflammatory hyperpigmentation (PIH). These marks often appear as flat, discolored patches, ranging in hue from brown to grey or purplish. Their formation involves an overproduction and deposition of melanin in the skin due to inflammation. Although benign, these marks can persist for several months or even years.
Home Remedies for Fading Marks
Several natural ingredients possess properties that can aid in fading hyperpigmentation. Consistency and patience are important when using these remedies, as visible improvements may take time.
Aloe vera
Aloe vera contains compounds like aloin and aloesin, which have skin-lightening properties by inhibiting melanin production. Apply fresh aloe vera gel directly to the affected areas once or twice daily. It is also recognized for its soothing and hydrating benefits to the skin.
Apple cider vinegar (ACV)
Apple cider vinegar (ACV) contains acetic acid and alpha hydroxy acids (AHAs), which can gently exfoliate the skin by removing dead skin cells. Acetic acid also inhibits melanin production, contributing to lighter spots. Dilute ACV significantly before applying it to the skin with a cotton pad.
Lemon juice
Lemon juice, rich in citric acid and vitamin C, acts as a natural bleaching agent and helps exfoliate the skin. Vitamin C aids in reducing melanin production. Due to its high acidity, lemon juice must be extremely diluted and used with caution to avoid irritation.
Turmeric
Turmeric contains curcumin, a compound with anti-inflammatory and skin-lightening properties. Curcumin helps regulate melanin production by inhibiting tyrosinase. A paste can be made with turmeric powder and water or milk, applied to the marks, and rinsed off after 15-20 minutes, though it may temporarily stain the skin.
Oatmeal
Oatmeal, particularly colloidal oatmeal, has soothing and anti-inflammatory effects. It also acts as a gentle exfoliant, removing dead skin cells. A paste made from finely ground oatmeal and water can be applied to the skin to calm irritation and support skin health.
Rosehip oil
Rosehip oil is rich in vitamin A, including retinoids that promote skin cell turnover, and vitamin C, an antioxidant that helps brighten the skin and reduce hyperpigmentation. Its essential fatty acids and antioxidants also contribute to tissue and cell regeneration. Apply a few drops of rosehip oil directly to the marks and gently massage into the skin.
Key Considerations for Home Treatment
Before applying any home remedy to a larger area, perform a patch test on a small, inconspicuous part of the skin. This helps check for any allergic reactions or irritation, and should be monitored for at least 24 to 48 hours. Discontinue use if any redness, itching, or irritation occurs.
Achieving noticeable results from home remedies requires patience and consistent application. Marks may take several months to lighten, and complete removal is not always possible. Sun protection is also important, as sun exposure can darken existing marks and hinder the fading process. Daily use of a broad-spectrum sunscreen with an SPF of 30 or higher on affected areas is recommended.
Some natural ingredients, especially acidic ones like lemon juice or undiluted apple cider vinegar, can cause dryness, redness, or even burns if not used correctly. Always adhere to recommended dilutions and discontinue use if any adverse reaction develops. Realistic expectations are also important, as home remedies may only lighten marks rather than fully erase them, and individual results can vary.
When to Consult a Healthcare Professional
Consult a healthcare professional, such as a dermatologist, if lichen planus marks do not show signs of fading after several months of consistent home remedy use. Professional guidance is also important if new lichen planus lesions appear, or if existing ones become active, itchy, or painful.
Seek medical advice immediately if any home remedies cause significant skin irritation, allergic reactions, or worsen the appearance of the marks. A dermatologist can also provide a precise diagnosis if there is any uncertainty, and discuss stronger, prescription-strength treatments. These may include topical corticosteroids, retinoids, or procedures like laser therapy.
