Can I get a skinPen and then a IPL/BBL 6 days later?

Hello,
I would suggest waiting at least two weeks after the SkinPen treatment to do any other treatments to your skin. The 2 weeks will allow your skin the repair from the SkinPen.

After a microneedling treatment, it's generally recommended that you wait at least two weeks before undergoing an IPL or BBL treatment. This allows your skin to fully heal from the microneedling procedure and reduces the risk of any adverse reactions when undergoing the next treatment.
Since both treatments involve stimulating the skin's natural healing and renewal processes, it's important to space them out to allow for appropriate healing time. Your skincare professional can provide specific guidance on the appropriate timing for your individual case based on your skin type, the extent of your skin concerns, and other factors.

you can do bbl or ipl on the same day as microneedling, no reason to wait. if you do want to wait I would do peel prep and then bbl/ipl with microneedling 5-10 days later. Best, Dr. Emer.
