Dealing with acne is challenging enough, but the marks they leave behind can be equally frustrating. These marks, resulting from post-inflammatory hyperpigmentation (PIH), manifest as discolored spots that linger long after the acne has cleared. Fortunately, with the right treatments, these marks can be significantly reduced.

Marks vs scars

It’s important to distinguish between acne marks and scars. Acne marks are color changes in the skin, while scars involve changes in skin texture, such as depressions or raised areas. PIH appears as flat, discolored spots that can be pink, red, brown, or black, caused by an overproduction of melanin during the healing process. Post-inflammatory erythema (PIE) appears as red or purple marks caused by dilated blood vessels near the skin’s surface during the inflammatory response to acne.

Top treatments for fading acne marks

Azelaic acid: Azelaic acid is effective in treating hyperpigmentation by targeting overactive melanocytes, reducing melanin production. Its anti-inflammatory and antibacterial properties also help treat active acne and rosacea. Products like the Ordinary Azelaic Acid Suspension can be beneficial in reducing discoloration.

Niacinamide: Niacinamide, also known as vitamin B3, gently reduces skin hyperpigmentation by inhibiting pigment transfer within the skin. It also improves skin elasticity and has anti-inflammatory properties, making it suitable for treating both PIE and PIH. Niacinamide is a great option for those with sensitive skin.

Vitamin C: A well-known antioxidant, vitamin C helps inhibit melanin production and boosts collagen production, aiding in skin repair and the reduction of pigmentation. Incorporating products like the Body Shop Vitamin C Glow Revealing Serum into your skincare routine can effectively target acne marks.

Retinoids: Retinoids, including tretinoin, adapalene, and tazarotene, are highly effective in treating both acne and post-acne marks. They promote cell turnover, which helps fade discoloration and improve skin texture over time. Retinoids are best used under the guidance of a dermatologist due to their potency.

Hydroquinone: Considered the gold standard for treating hyperpigmentation, hydroquinone works by inhibiting the enzyme tyrosinase, essential for melanin production. This reduces pigment formation in the skin, helping to lighten acne marks. Hydroquinone should be used with caution and typically under medical supervision to avoid potential side effects.
