Strategies for eliminating dark marks resulting from pimples: Solutions

Post-inflammatory hyperpigmentation (PIH) is a common condition in people of color, characterised by dark spots or discoloration following inflammation or injury to the skin. This article explores various treatment options, ranging from over-the-counter (OTC) products to prescription medications and procedures.

Topical Treatments

Topical treatments are a popular choice for treating PIH. Here are some effective options:

1. Hydroquinone: A common ingredient in both OTC and prescription products, hydroquinone helps lighten areas of darkened skin by inhibiting the production of melanin. However, it should be used under supervision due to potential side effects like skin irritation.
2. Kojic Acid: Available in OTC products, kojic acid inhibits melanin production and is often used in conjunction with other treatments.
3. Vitamin C: Known for its antioxidant properties, vitamin C can help brighten the skin and reduce hyperpigmentation. It is available in many OTC products.
4. Azelaic Acid: This naturally occurring acid is effective in treating hyperpigmentation and can be found in both OTC and prescription products.
5. Tretinoin and Mild Corticosteroids: Prescription-strength retinoids like tretinoin help exfoliate the skin, while mild corticosteroids can reduce inflammation.

Prescription Medications

In severe cases, prescription medications may be necessary. Here are some options:

1. Topical Retinoids: Besides tretinoin, other retinoids like adapalene and retinoic acid are effective for exfoliating the skin and reducing hyperpigmentation.
2. Oral Agents: In some cases, oral medications like doxycycline or isotretinoin may be prescribed to manage underlying conditions contributing to PIH.

Procedural Treatments

For more intensive treatment, procedural options are available:

1. Laser Therapy: Laser treatments, particularly those with a 1064 nm Nd:YAG laser, can target excess melanin but need to be used cautiously in darker skin tones due to the risk of further hyperpigmentation.
2. Radiofrequency (RF) Microneedling: This is a safer option for darker skin tones as it minimises the risk of PIH while promoting collagen production and skin rejuvenation.

Preventive Measures

Prevention is key in managing PIH. Here are some measures to consider:

1. Sun Protection: Essential for preventing further hyperpigmentation. Use sunscreens with at least 3% iron oxide and 20% zinc oxide.
2. Avoid Irritants: Decrease activities that cause skin irritation, such as close shaving or harsh skincare products.

Additional Considerations

• Consultation: It's crucial to consult a dermatologist to determine the best treatment plan based on individual skin type and condition.
• Combination Therapy: Often, a combination of topical treatments, prescription medications, and procedural treatments yields the best results for PIH.
• Appropriate Products: People of color should find and use appropriate products for their skin.
• Professional Help: People may choose to see a dermatologist if dark spots interfere with their personal, social, or professional lives.
• Studies: Studies have found promising results for the use of niacinamide, whole soy extract combined with retinol and salicylic acid, vitamin C, licorice root, and mulberry in treating PIH.
• Skin Lighteners: The AAD recommends avoiding skin lighteners that contain mercury due to the risk of kidney damage, nerve damage, and mercury poisoning.
• Improvement: Although most people with dark spots see improvement without medical treatment, sometimes additional support is necessary.
