Can I clean my face with the lait and lotion and put creams on my face just after having Botox and fillers injections?

You can definitely apply creams or lotions after Botox or facial fillers.  I tell my patients not to massage the treated area for 72 hours so that you do not affect the results.  Sunscreen should be applied daily.  

I ask my patients to leave their faces alone for 4 hours after injecting Botox or fillers.  After that time, they may continue with their normal cleansing and moisturizing after Botox treatment, but should avoid anti-aging products, massaging or exfoliating for 1 to 2 days after fillers to prevent any irritation.
