Bruises happen to all of us — from a fall, a sports injury, or after plastic surgery.
But have you ever wondered why they turn that distinctive shade of blue or purple?
Why Bruises Form: It Starts with Bleeding
Red blood cells are the most abundant cells in the human body. They circulate continuously through arteries, capillaries, and veins — and under normal conditions, they stay within the blood vessels.
But when blood vessels are damaged — by physical impact or surgery — red blood cells can escape into the surrounding tissue. The more blood that leaks out, the darker and more pronounced the bruise becomes.
Once bleeding occurs, the immune system gets to work — clearing out the pooled red blood cells and other byproducts. But this cleanup takes time, which is why bruises tend to linger.
How to Make Bruises Fade Faster
The first priority is stopping the bruise from spreading. For the first 24 to 48 hours, apply a cold compress to the affected area — this helps constrict blood vessels and limit further bleeding.
Once the initial bleeding has stopped, switch to a warm compress to promote circulation and help the body clear the bruise more quickly.
Even with these measures, waiting for a bruise to fade naturally can take longer than expected — and when it's somewhere visible, like the face, it can affect your confidence and daily routine.
A Korean Medicine Approach: Treating Blood Stasis
In East Asian traditional medicine, there is a concept called "eohyeol" (어혈) — meaning stagnant or pooled blood. It maps closely to what we understand as bruising.
Korean medicine has long used specific herbal combinations to treat them — and recent research has confirmed their effectiveness.
- Safflower (Honghua): Contains safflor yellow, which promotes blood circulation and helps break down blood clots and stasis.
- Moutan Bark (Mudanpi): Derived from the peony tree, it contains paeoniflorin — a compound with well-documented anti-inflammatory, antioxidant, and anti-cancer properties.
This herbal combination — formulated specifically to reduce bruising and swelling — has been named ReEnSta (Remove Edema & Stasis), and has been granted patents in both Korea and the United States.
Reduced Swelling, Pain, Inflammation and Bruising
Research results show that ReEnSta produces significant improvements in post-surgical swelling.
In a foot surgery study, the control group (no treatment) saw foot volume increase to approximately 200% of baseline — and this remained elevated for 14 days. In the ReEnSta group, swelling was reduced by up to 69.1% by day 14.
For pain, inflammation, and bruising, the results were equally striking. Pigmentation in the control group increased to 37.8 times the normal level — while in the ReEnSta group, it reached only 1.8 to 2.3 times normal. This indicates that ReEnSta effectively prevented blood from pooling in tissue after surgery.

In short: when taking ReEnSta, bruising-related swelling, pigmentation, pain, and inflammation markers decreased more than twice as fast compared to no treatment.
The research has been published in the Journal of Surgical Research — an SCI-level international academic journal in the field of surgery. (Read the paper)
Whether your bruise is from an accident, sport, or cosmetic surgery, adding a Korean medicine approach to your recovery may be worth considering.
It's a gentle, low-burden way to support healing — and get back to your daily life a little sooner.
