Thank you for your question. Rolling scars are a type of depressed acne scars and are commonly formed in response to inflammation caused by acne. They have gentle sloping edges that give overlying skin a wave-like appearance, and this is a result of fibres that tether to the bottom of the scar. Collagen-stimulating treatments such as rejuran are effective for rolling scars and they have semi-permanent effects. Collagen stimulated is as lasting as your own aging process.
Rejuran, Rejuran S, and acne scars
If Rejuran is to be used for acne scars, it should be done with subcision concurrently. There should be an immediate improvement (and plumping) in the scars to show Rejuran placement, otherwise, it might not have been done properly. The main ingredient in Rejuran is a biological molecule called polynucleotide which is designed to repair the skin through its wound healing and anti-inflammatory properties. Rejuran S (scar) is a specialised variant of Rejuran designed for treating depressed acne scarring, and it contains a higher viscosity while retaining the same PN concentration. By being more viscous, it is able to plump up depressed scars and create a scaffold for collagen formation. Whether you are suitable for Rejuran depends on your individual scar type and skin type, and it should only be used when recommended by an experienced physician.
Often, a combination of procedures will yield superior results compared to one procedure alone. Subcision is an excellent choice in the treatment of rolling acne scars, as it releases the upper skin from firm fibrous bands that anchor it to deeper structures. It can also be combined with dermal fillers or Rejuran S for better collagen regeneration. Other treatments for rolling scars are fractional lasers that resurface the skin and stimulate collagen growth, as well as radiofrequency microneedling. However, these procedures might not be completely targeted and break up fibrous tissue tethering the scars and will require multiple sessions for better effect. Hope this answers your question!
