When should i stop using the creams that are used before laser-resurfacing?

I recommend following up with your Doctor's about their skin care recommendations prior to and after treatment. Laser results take 6-12 weeks to settle. Photodynamic therapy can help healing. Lasers like Co2 work best in combination with other treatments in order to improve the skin's texture and collagen. After Co2, I recommend adding fraxel lasers, microneedling/prp and radiofrequency treatments. See an expert. Best, Dr. Emer.

Thank you for your question soso25_. Fractional CO2 laser resurfacing is an
outstanding treatment that can address multiple aspects of aging in a single
treatment. I recommend that my patients discontinue hydroquinone-containing products and retinoids one week before and after a treatment. Please consult with a doctor for specific
recommendations. Good luck!

You should stop things like retin A or hydroquinone and any other acids used at least 4 days beforebest,Dr. Malouf
