rejuran s scar acne scar

We frequently see many patients who request help with acne scar treatments As Rejuran S was introduced to the market subsequently after Rejuran Healer, these patients are unsure what the differences are. 

One of our patients’ top priorities and concerns is whether they can heal their scars permanently and naturally. This is especially for deep and depressed scar indentations, such as ice pick scars. In this review, find out how Rejuran S can help and how it differs from Rejuran Healer.

What is Rejuran S and how is it different from Rejuran Healer?

Rejuran S (Scar) is an injection treatment that stimulates collagen repair, regeneration, and remodelling. It is a specialized version of Rejuran Healer. The key ingredient is Polynucleotide (PN) derived from salmon DNA, which repairs damaged skin cells and restores natural skin structure. Thus, it can plump up depressed acne scars that cannot be healed just by laser treatment alone. 

Both versions have the same percentage of Polynucleotide (PN). However, Rejuran S contains an improved version of PDRN, with higher viscosity and stronger regenerative properties. It is designed to repair deep and depressed acne scars, including ice pick scars. Rejuran Healer is of lower viscosity; hence it can treat wider affected areas. It is suitable for patients whose acne scars require broad coverage of body areas. Our doctors recommend Rejuran Healer as an initial treatment to repair the entire affected area, followed by Rejuran S to target individual deep and depressed scars.

Why Rejuran S works for scar removal

Reason #1: Long-lasting or permanent removal of acne scars

Using the PN technology of optimal viscosity, Rejuran S can target depressed, and ice pick scars of varying severity to stimulate healing from within. It enables scar repair and healing deep within the skin by working at the skin’s DNA level. Treatment progress is gradual, progressive, and natural, with generally long-lasting or permanent results. There is a significant reduction in acne scars, marked improvement in skin texture, smoothness, smaller pores, and less oily skin. Collagen production starts 28 days after the treatment, with gradual and progressive lifting. Each treatment builds on the previous one resulting in the amazingly natural restoration of facial contours and lift.

Reason #2: Natural healing of acne scars from within

In our doctors’ practice, they usually encounter patients who prefer natural methods for acne scars rather than “artificial” methods. Rejuran S may be ideal for such patients who prefer natural bio-compatible properties. Check out our article on how Rejuran Healer can heal acne scars naturally. 

Reason #3: Minimal downtime 

Rejuran S acne scar removal treatments have very minimal downtime, also known as the recovery period. Many patients can return to work and resume normal activities immediately after treatment. As a simple and minimally invasive procedure, Rejuran S is suitable for busy executives and working adults. Since Rejuran is compatible with human skin, it does not trigger any negative immune response. Therefore, it has minimal side effects. It is suitable for all skin types, even sensitive skin.

Reason #4: Capable of healing ice pick scars 

Ice pick scars, in particular, are difficult to treat. They usually appear as deep, narrow and depressed indentations on the patient’s skin. Some treatments may work well on other types of scars but have a limited effect on Rejuran S. Depressed scars form due to insufficient collagen production when the acne wound is healing, causing the skin to sink. Rejuran S can induce collagen production and restore the skin structure to fill sunken scars while repairing the skin’s dermis. 

Reason #5: Versatile treatment 

Rejuran S is a versatile treatment as it can target different acne scars, be it ice pick scars, rolling scars, or box scars. It can be used as a stand-alone product or combined with other treatment options to create a holistic scar treatment protocol. Rejuran S also provides skin rejuvenation and lifting properties for wrinkled and sagging skin, ageing skin, sensitive skin, and dry skin. Patients have noted a glow and radiance in skin, smoothness, reduced fine lines, and improved hydration. Overall, there are age-reversal and youth-regenerating effects.


Depending on the scars’ type, severity, and extent, Rejuran can be used either as a stand-alone product or one of the tools used as part of a customised acne scar treatment in Singapore protocol designed by our doctors. With a collective experience of more than 40 years in the medical and aesthetic field, along with personal experience in acne scars, our doctors are always on the lookout for innovative, creative protocols in acne scar removal.
