Rejuran Intervals: How Many Weeks Apart Are the First Few Sessions?

The basic approach to Rejuran intervals is to receive about three sessions in a row at 3- to 4-week intervals at first, and then widen the interval for maintenance based on skin condition. Even within Rejuran, the recommended intervals differ slightly for Healer, HB+, and the scar formulation, and there are individual differences depending on skin thickness and recovery speed.

Why are Rejuran intervals set at 3 to 4 weeks?

PN (polynucleotide), the main ingredient of Rejuran, enters the dermis and works by supporting an environment in which the skin recovers on its own. This change doesn't end right after the injection but continues over several weeks, so the next session should be given around the time the changes from the previous session settle in, allowing changes to build up step by step.

If the interval is too short, you end up being injected in the same spot again before the bumps and swelling from the previous session have fully subsided, and if it is too long, the changes between sessions don't carry over, which can make it hard to notice any difference.

Rejuran Intervals That Vary by Formulation and Stage

• Rejuran HB+, which also contains hyaluronic acid, is based on at least 3 sessions at 2- to 3-week intervals.
• Rejuran S, a highly viscous formulation for scars, is usually given for 3 to 4 sessions at intervals of about 2 to 4 weeks.
• The maintenance interval after completing the initial sessions is set in units of months, based not on a fixed number but on when skin texture and firmness start to decline again.

If you are also having laser or lifting treatments, the order and intervals need to be decided as well. Some combinations can be done back to back on the same day, while others prolong recovery because swelling and heat overlap, so the order is divided according to your schedule during examination and consultation. At our Suwon clinic, we advise receiving Rejuran Healer for 3 sessions, usually at 3- to 4-week intervals, and then continuing with maintenance treatments depending on skin condition.

FAQ

Q. If I get Rejuran every 2 weeks, will the changes come faster?

A. Shortening the interval doesn't make changes come proportionally faster. Time is needed for the injection marks and swelling from the previous session to subside and for the regenerative response to progress, so the baseline is 3 to 4 weeks for Healer and 2 to 3 weeks for HB+, adjusted according to how your skin responds.

Q. After completing all 3 Rejuran sessions, when should I get it again?

A. It is decided by skin condition rather than a fixed date. The changes built up in the initial sessions gradually fade with lifestyle habits and aging, so when you feel that your skin texture and firmness have declined again, get an examination and set the maintenance interval.

Q. If I miss my Rejuran interval, do I have to start over from the beginning?

A. Being a week or two late doesn't mean you need to start over from the beginning. However, if the interval stretches to several months, the changes from earlier sessions may not carry over, so your current skin condition is reassessed and the remaining sessions and intervals are adjusted.
