As you experienced, microdermabrasion and peels are advanced forms of exfoliation that help shed dead skin cells and encourage the new ones to healthily glow. Because of the advanced nature of the treatment, there are some important things to expect and do's and dont's to keep your skin happy over the next few days.
THINGS TO EXPECT
Rosy skin afterwards is perfectly normal right. Your treatment gave your skin healthy stimulation, and any flushness or light heat should calm by the next day.
Pore detoxing. Your treatment helped purge debris that’s been trapped below a buildup of dead skin cells. If you follow proper post-care, any small breakouts you may experience shouldn’t linger (and you may see few to none at all!).
Slightly drier skin. Minor flaking can occur. Moisturizer is your single most important tool for the next few days. Be consistent and be generous – it will help your skin recover quickly and will actually help keep you from breaking out unnecessarily.
THINGS TO DO
Generous sunscreen (and direct sun avoidance) is an absolute must. You should do this everyday, but it’s extra important now that some very youthful skin cells are at the surface.
Treat your skin gently over the next several days. Use a gentle cleanser, avoid scrubbing motions, and gently pat your face dry after washing and/or showering (or with your workout towel).
Moisturize like a maniac. Twice or more daily, and even in areas where you’ve been concerned about excess oil or buildup of blackheads. As long as the moisturizer is suited to your skin type, you’ll actually see a clearer result.
Drink water! It's a myth that water directly hydrates skin, but hydration is important for whole-body health and to keep those fresh skin cells hydrated from the inside out.
For extra credit, use a gentle hydrating mask or balm at night.
THINGS TO AVOID
Avoid lengthy, direct sun exposure for 3 days, like major pool or beach time.
Don’t exfoliate for another 3-5 days. No scrubs, at-home peels, no matter how gentle. Also, don’t wax or receive any laser treatments for 5 days. For gents, don’t shave for 24 hours.
Avoid heavy sweating workouts until the next day (bikram yoga, major cardio, etc.). Your sweat may cause stinging and irritation. Avoid saunas and steam rooms for the same reason. If you do have to workout, just be aware of your face's sensitivity and pat your sweat very gently or wear a headband, hat, or bandana to absorb sweat before it hits your face.
Avoid products with retinol, Vitamin C, AHA/BHA acids, benzoyl peroxide. You just had a facial – go easy!
