After using a medicinal solution to remove a spot, the red mark turned into a dark mark once the scab fell off. Can it still improve?

After the scab falls off following spot treatment with chemical solution, the red mark turning into a dark mark is generally reversible, but if the pigmentation is deep, it may not resolve completely. The details are as follows:

1. Can improve

The darkening of marks after scabbing from chemical spot treatment is usually due to post-inflammatory hyperpigmentation caused by skin inflammation or injury. Over time, the dark mark will gradually fade and eventually disappear. This process may take some time, but recovery can occur naturally through the skin's metabolic turnover.

2. May not improve

However, some dark marks may result from deeper pigmentation, inadequate skincare during the inflammatory phase, or other underlying pathological factors. In such cases, the dark marks might not fully disappear. For fundamental removal of persistent pigmentation, laser treatment under medical supervision may be considered.

In summary, there is a chance of recovery when red marks turn dark after chemical spot treatment and scab detachment, but this requires time and appropriate treatment methods. Individuals with scar-prone skin types may find improvement more difficult. If the dark marks significantly affect appearance, it is recommended to consult a dermatologist for accurate diagnosis and personalized treatment advice.
