Next, we will explain in detail what distinguishes these two dermatological conditions.
What is purple?
La purple is a medical term used to describe red or purple spots on the skin that do not go away when you press on them. These spots occur due to a Bleeding under the skin, caused by the rupture of small blood vessels called capillaries. Purpura can appear as small spots (petechiae) or larger spots (ecchymoses).

- Drug reactions
- Vitamin deficiencies (especially vitamin C and K)
What is ecchymosis?
La ecchymosis, commonly known as a bruise or bruise, is a blue, purple, or yellowish spot that appears on the skin due to a Trauma or blow. Unlike purpura, ecchymosis is caused by the rupture of larger blood vessels, causing more extensive bleeding under the skin.

- Bumps or bruises
- Trauma
