For Platinum 13, leave it on for about 5 minutes , then rinse it off. Platinum Skin Care says there’s no added benefit to leaving the TCA on longer, even if it still stings.

What to expect

  • Face: peeling usually starts on day 2–3 and is often finished by day 6–7.
  • Body: peeling may not start until day 10–14.
  • Some people using 13% TCA report visible peeling in about 5–10 days overall.

Safety note

If this is your first time using it, follow the product’s peel directions closely and stop if you have severe burning, blistering, or unusual pain. Platinum’s guidance also says timing can vary by skin type, strength, and number of layers.
