Rejuran not working simply means that Rejuran does not always look visibly effective straight away. Results are usually subtle and build gradually, because Rejuran with polynucleotides is used to support skin quality and the skin’s natural repair processes.
Improvements in skin texture, hydration and elasticity may only become more noticeable after several sessions. On this page, you can read why results may feel disappointing, which factors can influence the outcome and when to contact your clinic or practitioner for advice.

Rejuran can take longer to show visible change than some people expect. This is because it is not designed to add instant volume. It is mainly used to support gradual improvement in skin quality.
Possible reasons include:
Too few sessions
Most people need more than one session. Expecting a major change after a single treatment may lead to disappointment.
Judging the result too early
The skin needs time to respond. Subtle improvement may become clearer after a few weeks.
Expectations that do not match the treatment
Rejuran is not a filler. It does not give immediate volume, but focuses more on skin texture, hydration and fine lines.
Skin condition and treatment indication
For deep lines, marked skin laxity, hollows under the eyes or clear volume loss, Rejuran may give a less noticeable result.
Results vary from person to person. Skin type, age, skin condition, lifestyle and the number of sessions can all affect the outcome.
Moment | What you may notice |
|---|---|
Immediately after treatment | Mild redness, swelling or small bumps |
After a few days | The skin usually settles |
After 2 to 4 weeks | Subtle improvement in skin texture and hydration |
After several sessions | A clearer effect on fine lines and skin quality |
For realistic expectations, also view the page about Rejuran before and after results.
For most people, one Rejuran treatment is not enough to see a clear result. The effect usually builds after a course of several sessions.
The number of treatments needed depends on your skin, the area treated and the goal of the treatment. Discuss this during a consultation with a doctor, nurse prescriber or experienced aesthetic practitioner.
Rejuran is mainly used to improve skin quality. It may help with hydration, fine lines and uneven skin texture, but it does not give immediate volume in the way fillers can.
If your main concern is deep folds, hollow areas or volume loss, a filler or combination treatment may be more suitable. Not sure whether you need skin improvement or volume restoration? Read the comparison between Rejuran and fillers.
Rejuran is not always the best option for every skin concern. Results may be less obvious for:
Deep wrinkles or significant skin laxity
Hollows under the eyes
Clear volume loss
Active acne
Some scars, depending on the scar type and product variant used
A careful assessment is especially important around the eye area. Read more about Rejuran under the eyes for fine lines, dark circles and thin skin.

Contact your clinic, doctor or practitioner if you are unsure about healing, the result or possible side effects.
You should ask for advice if you notice:
Unusual redness, pain or swelling
Little or no visible change after a full course
Questions about follow-up sessions
Doubts about whether Rejuran is the right treatment for your concern
If you are not happy with the result, book a follow-up consultation first. A practitioner can assess whether your skin has had enough time to respond and whether further sessions may be useful.
It may help to:
Compare before and after photos
Discuss whether your expectations were realistic
Ask whether another treatment may be more suitable
Have your skin reassessed by an experienced clinic or practitioner

The result may be subtle or may only become visible after several sessions. Skin type, age, skin condition, lifestyle and treatment technique can all affect the outcome.
Yes, this can be normal. Rejuran works gradually, and most people need several sessions before the effect becomes clearer.
Many people notice subtle improvement after 2 to 4 weeks. The full effect is usually clearer after a course of treatments.
Technique is important. Choose an experienced doctor, nurse prescriber or aesthetic practitioner, and contact the clinic if you are unsure about the result or recovery.
If you have clear volume loss, deep folds or significant skin laxity, fillers, skin boosters or a combination treatment may sometimes be more suitable.
Discuss this with your practitioner first. Another session may help in some cases, but another treatment may better match your skin concern.
Rejuran S may be considered for some types of scarring, but results depend on the scar type, skin condition and treatment plan.
