Treatment

Post-inflammatory hyperpigmentation (PIH) is an acquired pigmentation disorder that develops in response to skin damage and inflammation, particularly in skin folds such as the armpits. Factors like friction, hair removal, and the use of topical irritants generate this type of reaction, which is more evident in skin phototypes III-VI.

Clinically, it manifests as symmetrically distributed hyperpigmented plaques with a significant aesthetic impact. One of the most widely used strategies is the application of depigmenting agents that reduce melanin production, control local inflammation, and promote cell renewal. Furthermore, nanosecond Q-switched laser treatment plays a relevant role in the treatment of hyperpigmentation, especially when there is deeper pigmentation or when a safe approach is desired for all skin phototypes.

The ACROMA-QS® Q-Switched laser handpiece is compatible with the ETHEREA-MX® and ZYE® platforms. When used at low fluence, at a wavelength of 1,064 nm Nd:YAG in "laser toning" mode, it provides progressive lightening, improved texture, and virtually no downtime, allowing the patient to immediately return to their activities.

The treatment consisted of four sessions with ACROMA-QS® laser technology, without the need for a home treatment regimen. After the treatment cycle, progressive lightening was observed, with significant clinical improvement and homogenization of skin tone. This case highlights the effectiveness of laser technology for the treatment of post-inflammatory hyperpigmentation located in sensitive areas.
