When you apply salicylic acid to a pimple, it can turn white due to a few reasons:
- Salicylic acid is drying: Salicylic acid is a powerful keratolytic agent, meaning it breaks down the keratin that forms the walls of clogged pores. This can lead to the pimple drying out and appearing whiter.
- Inflammation reduction: Salicylic acid can help reduce inflammation, which can make the pimple less red and more prominent.
- Pus coming to the surface: In some cases, salicylic acid might help bring the pus closer to the surface of the pimple, making it more visible and white.
- Skin purging: This is a common reaction to using a new skincare product, including salicylic acid. It occurs when the product speeds up skin cell turnover, causing deeper-lying pimples to rise to the surface. This can lead to a temporary increase in acne before it clears up.
While a white pimple might look concerning, it generally indicates that the salicylic acid is working. If you have concerns, consult a dermatologist.
