Does the sun affect how your face looks 3 days post needling with PRP?

This is tough to answer without pictures, but sun protection is essential after microneedling. I find that prp after microneedling helps improve redness. I recommend following up with your Doctor about after care after your microneedling treatment. I always combine microneedling lasers for best outcomes. See an expert. Best, Dr. Emer

After microneedling, you would want to follow a gentle skin care regimen and be diligent with sun protection for at least 2 weeks so that the new skin is smoother and more even in color.  If you are experiencing persistent or worsening redness, I would recommend following-up with your provider to ensure that your are healing properly.

Sun exposure is not recommended after microneedling, especially when your face is still red. Use a good quality sun block  even if you are not in the sun. Exposing your face to the sun is never a good idea since it will increase your wrinkles, damage your DNA, make the skin dull and incourage hyperpigmentation.

Hello and thank you for your question.
You do want to avoid sun until the redness is gone. The skin has been traumatized and you need to allow for healing. Heat will also effect the healing process. Try to stay cool the first few days and follow your post procedure instructions. Using a calming cream will help the healing process, ZO Revitatrol is excellent for aiding in post procedure healing. Then you are out wear your sunscreen and sun protection to avoid direct exposure. The skin will begin to heal
Best to you,

Realistically if you have receive a small amount of UV it will not affect your microneedling PRP procedure 3 days after. However because your skin pigment cells maybe 'active' after trauma, prolonged exposure is not recommended, especially if energy based microneedling was used. Follow the guidelines as specified by your specialist, and your skin will heal up just fine. Dr Davin Lim.
