Yes, salicylic acid can help in clearing hyperpigmentation, particularly post-acne hyperpigmentation.
How Salicylic Acid Addresses Hyperpigmentation
Salicylic acid is a beta-hydroxy acid (BHA) known for its exfoliating properties. It works by penetrating the pores and shedding dead skin cells from the surface. This process can help reduce the appearance of various forms of hyperpigmentation, such as dark spots and patches caused by acne, sun damage, or inflammation.
Targeting Post-Acne Marks
One common type of hyperpigmentation that salicylic acid is effective against is post-inflammatory hyperpigmentation (PIH), often seen after acne breakouts.
- According to the CHOSEN Store blog, "A regular usage of the potent Light Routine® Gentle salicylic acid peel, works to clear the persistent post acne hyperpigmentation." This highlights its utility in tackling marks left behind by acne.
By promoting skin cell turnover, salicylic acid helps to fade these darkened areas over time, revealing fresher, more evenly toned skin underneath.
How Exfoliation Helps
The mechanism through which salicylic acid aids in removing hyperpigmentation involves:
- Exfoliation: It loosens the bonds between skin cells, promoting shedding of the pigmented upper layers.
- Increased Cell Turnover: Encouraging faster replacement of old, discolored cells with new ones.
- Improved Penetration: Clearing the skin surface can potentially allow other treatments to work more effectively.
While salicylic acid can significantly reduce the appearance of hyperpigmentation, the extent of removal can vary depending on the severity and type of discoloration. Consistent and appropriate use is key.
