I've recently been researching skincare ingredients and came across salicylic acid serum. It seems to be gaining popularity for its purported benefits in treating acne and improving skin texture.

I'm curious to hear from those who have tried salicylic acid serum:

1. What specific skin concerns were you hoping to address by incorporating salicylic acid serum into your skincare routine?
2. How long have you been using it, and what changes have you noticed in your skin?
3. Have you experienced any side effects or challenges while using salicylic acid serum?
4. Do you have any tips or recommendations for using salicylic acid serum effectively?
