How often should I use Ren Aha body serum?
Good day, I'm curious about the recommended usage frequency for Ren Aha body serum. I understand that it's a potent product, but I'm unsure if I should be using it daily or a few times a week. Could you please clarify the ideal usage pattern for this product to ensure optimal results while avoiding any potential skin irritation? Thank you for your time and expertise.
