Potenza vs. Secret RF: Scars or Pores?

Potenza and Secret RF are both RF microneedling devices built on the same core mechanism, but they aren't interchangeable for every concern. Here's how their tip range and depth control differ, and which one tends to fit scars better versus pores.

Rejuran or Rejuran HB: How Do You Choose?

When to Pause Retinol Before a Laser or Peel

Retinol thins and sensitizes the skin's surface, so most providers recommend pausing it for several days before a laser or peel and watching skin signals, not just a calendar date, before restarting.

Red, Bumpy Skin After a Skin Booster: Normal?

If your skin looks red and a little bumpy right after a skin booster, that's usually just how the injections settle in, not a sign anything went wrong. Here's what's typical, how long it lasts, and which signs are worth a second look.

Secret RF Sessions: How Many & How Far Apart?

Secret RF isn't a one-and-done treatment — most providers plan it as a series of three to four sessions, spaced about a month apart, so your skin has time to rebuild collagen between visits.
