Hi,
There are much more effective and proven treatments for acne scars such as subcision, fractional lasers and micro-needling that you should consider first.
Rejuran Healer may be the current craze for anti-ageing treatment but it is more targeted at maintaining skin health by stimulating natural collagen synthesis in the upper dermis. In my opinion, understanding that acne scars are caused by rather deep disorganized collagen tissue following previous intense acne inflammation, Rejuran Healer is not likely to offer significant long-lasting benefits for acne scars except for very mild superficial ones.
Perhaps, when the experience with the use of Rejuran Healer increases with time, an update will clarify which situations it works well in and which it doesn’t.
Hope this helps!
