If you feel strong burning, swelling, rash, or persistent discomfort, stop use and keep the routine simple. For severe or worsening symptoms, contact a medical professional.
Need Help?What not to mix.
Most avoidable problems come from using too many strong products at the same time.
Night active care
When using Tone Correction Night Treatment, avoid layering with strong exfoliating acids, retinoids, or harsh peeling products in the same routine unless your skin is already tolerant.
Sensitive skin
Start slowly, moisturize well, and patch test when trying a new formula. If irritation appears, pause use instead of adding more products.
Still not sure?
If you need help with use, discomfort, no visible result after consistent use, or an Amazon order issue, start a support request.
