PROBLEM
Controlling bleeding during microneedling and subcision of acne scars is difficult. To reduce bleeding during or after the procedure, we usually use a large cotton ball or gauze piece, depending on what is available. The cotton fiber is hydrophilic in nature and is helpful in controlling bleeding. However, because cotton is a hydrophilic fiber, it absorbs a greater amount of blood, resulting in increased blood loss.[1,2] Furthermore, after removing these cotton fibers, there is a risk of re-bleeding due to better adhesion with blood clots, which requires more time and staff to control bleeding [Figure 1a and b]. On the other hand, hemostatic gauze containing polydimethylsiloxane and cellulose nanocrystals is a highly effective, anti-adhesive (160°) in nature, and hydrophobic approach to this problem that is not widely accessible.[3]

SOLUTION
We recommend a customized cotton fiber for easy control of post-microneedling and subcision bleeding. The cotton ball (hydrophilic) is made of cotton fiber, which is split by tugging apart with a finger to produce fluffy cotton fiber [Figure 2 and Video 1]. Following microneedling and/or acne scar subcision, these tiny fluffy fibers are applied to bleeding points for 1–2 min [Video 2]. These thin cotton fibers help to manage bleeding without interfering with subsequent procedures. Thus, these hydrophilic small cotton fibers aid in reasonably clean microneedling and subcision of acne scars by minimizing post-procedure bleeding.
