For how long should I apply sunscreen after microdermabrasion when going outside?

sunscreen should be used daily with oral heliocare, microderm does very little to irritate the skin. start with EMERAGESKIN fusion shield and then use ISDIN sunscreen when out by pool or in sun. I suggest
at home peels like cosmelan, enlighten and aerify along with dermarolling (MTS roller with anteage MD ampules weekly, see link) should be started now to prevent further aging.

For facial rejuvenation, I would suggest a combination approach of
1) skin care with products and PRP/microneedling
2) PDT light therapy few times a month with growth factors
3) laser treatments like clear and brilliant regularly and a few times a year Fraxel/halo Viva, Co2/Erbium
4) Sculptra injections a few times a year for collagen production with fillers like juvederm/restylane/belotero/radiesse/bellafill
5) thermage/ultherapy for yearly skin tightening with or without PDO or cone based instalift threads for lifting
6) botox every 2-3 months to stop movement lines and prevent lines at rest
7) deep microneedling RF like Fractora/morpheus8 for tightening of the skin
8) Vascular laser like vbeam/excel V or BBL forever young treatment every quarter (3-4 months)

Best, Dr. Emer.

Thank you for your question. It can be confusing to understand what is the best post procedure protocol for facial aesthetics. First, always listen to the recommendation of your physician or esthetician providing the service. The rule of thump, is to always apply a sunscreen daily. This should be part of your daily regimen. There are so many amazing SPFs on the market. Always look for an SPF of 30+. There are sunscreen that also provide protection of IR and blue light. It's not just a protection from UVA/UVB.

Hello, and thank you for your question! While you should apply sunscreen after a microdermabrasion treatment you should really be applying sunscreen to your face daily as well.
