Spot Treatment Gel for Exfoliation and Dark Spots

Subject: Spot treatment formula for skin exfoliation

Regarding your question about a spot treatment gel formula to accelerate skin exfoliation for dark spots from scars and acne, and the appropriate concentration for Salicylic Acid (BHA):

Based on the staff's recommendation, Salicylic Acid is generally more suitable for dissolving clogged pores. For accelerating skin exfoliation and targeting dark spots, Glycolic Acid (AHA) or Capryloyl Salicylic Acid (LHA) are suggested instead.

• If using Glycolic Acid (AHA), for spot treatment, a concentration of 20-40% can be used.
• If using Capryloyl Salicylic Acid (LHA), for spot treatment, a concentration of 5-20% or higher can be used.

These ingredients are considered more effective for the specific issue of dark spots and accelerating skin cell turnover compared to Salicylic Acid.
