How to Remove Post-Acne Hyperpigmentation
The so-called “acne marks” refer to post-inflammatory hyperpigmentation (PIH) that may remain after acne lesions have resolved—either through treatment or spontaneous resolution of inflammation. This type of hyperpigmentation commonly appears as black, brown, or red discoloration. So, how can one effectively remove melanin deposits associated with acne marks? Below are some practical solutions.

How to Remove Melanin Deposits in Acne Marks
1. Brightening Skincare
When melanin deposits appear as acne marks, topical brightening skincare products can be used to accelerate skin cell turnover and melanin metabolism, while simultaneously inhibiting new melanin synthesis—thereby helping prevent and reduce hyperpigmentation.
2. Preventing Skin Dryness
During dry weather, the skin tends to become dehydrated. Excessive dryness and insufficient moisture can exacerbate the appearance of acne marks. Therefore, maintaining adequate skin hydration is essential for improving melanin deposition. Hydration should not be overlooked; it is generally recommended to use hydrating masks two to three times per week.

3. Sun Protection
Sun exposure significantly contributes to the development and worsening of post-acne hyperpigmentation. Thus, effective sun protection is crucial for achieving brighter, more even-toned skin. In addition to daily application of broad-spectrum sunscreen and primer, physical sun protection measures—such as wearing wide-brimmed hats or carrying an umbrella when outdoors—are highly recommended. It is also advisable to avoid outdoor activities during peak UV hours (typically between 10 a.m. and 4 p.m.).
4. Professional Brightening Treatments
For severe cases of melanin deposition in acne marks, professional clinical treatments—including chemical peels, laser therapy, or microdermabrasion—may be considered under the guidance of a dermatologist.

The above outlines effective strategies for reducing melanin deposits associated with acne marks. We hope this information proves helpful.
