Welcome @dmswinnea, I moved your question about senile purpura and lessening the effects of bruising on thin skin to this existing discussion:
- Senile purpura bruises and treatment options: https://connect.mayoclinic.org/discussion/hiding-old-lady-bruises/

I did this so you can see what members are suggesting and connect with others like @ellerbracke @jilliemo12345 @contentandwell @jnb @liene @alohamelanie @notmoff @bimshire and more.

Hi, @dmswinnea As you can see in this topic, there are many ideas. I did have some success with tretinoin. It wasn't 100% but it was better than nothing. Now, since I am no longer on prednisone, I have fewer purpura.

Ask your dermatologist for a prescription. By the way, since it is considered to be a cosmetic problem, Medicare does not pay for it. If you use the app GoodRx you can find it for a good price though.
