Immediately after treatment:
- Pain or a burning sensation is often present during and immediately after skin needling. After treatment, the skin will be red and swollen and may bleed. The redness and swelling are normally mild and disappear in 1-3 days at most.
- There is no need to apply a special dressing after skin needling. Sometimes, gentle pressure with a gauze is applied to stop the pinpoint bleeding. Your doctor may recommend using a moisturizer in the day or two following treatment.
- After treatment, it is important to avoid sun exposure and apply sunscreen until the skin is healed.
Days and weeks after treatment:
- Skin redness and swelling may persist up to 3 days at most. When the skin heals, crusts may form.
- During this time, patients should continue to avoid sun exposure and apply sunscreen.
Long-term side effects are rare, but may include hyperpigmentation (skin darkening), which is more common in dark-skinned individuals.
