You can get a minor sunburn-like burning sensation after the treatment, but this should pass in a few hours. A few days of skin redness are possible and usual. A little degree of swelling could exist. It is rare and not dangerous to develop blisters or crusting. After a few days, pigmented patches could start to peel but it’s extremely important to not touch these areas and let them fall on their own.

• Use cold compresses during the first 24 hours for comfort.

• Skin may feel delicate for 1-2 days, do not touch the skin at this period.

• Use mild cleaners and refrain from using loofah or Clarisonic that may cause irritation for 1 week.

• Avoid using retinoids, tretinoins, alpha- or beta-hydroxy products, vitamin C products, exfoliating the treated region for 1 week.

• Use sunblock daily and re-apply every 2h while avoiding excess sun exposure. SPF 50 is highly recommended.

• Don't subject the treated area to extreme heat or friction such as heavy exercise, saunas.

• Sun spots and age spots will darken sometimes before they start to react and disappear. Once they've dried up, don't pluck those areas. They will rise and fall by themselves.
