5 Reasons Seniors On Blood Thinners Are Covered In Purple Bruises (And The 60-Second Cream Dermatologists Wish They'd Recommended Sooner)
Bruise from the slightest touch? Arms covered in purple patches you don't remember getting? Told it's "just aging"? Here's what's really happening under your skin.

If you're over 60 and your arms look like you've been in a fight…
And you can't even remember bumping into anything…
I need you to read this before you pull on another long-sleeve shirt.
Because those bruises are not "just aging." They have a cause. And once you fix the cause, the purple stops taking over your arms.
Here are the 5 things 30 years of treating aging skin have taught me.
#1: Your Skin Has Lost Its "Cushion"
We call it dermatoporosis. Osteoporosis… but of the skin.
After 60, the skin on your forearms and hands loses up to half its thickness.
The cushion that protected your tiny blood vessels? Gone.
Now a seatbelt, a handbag strap or a grandchild's hug is enough to snap them.
Blood floods under the skin. A flat, dark purple stain appears. And it sits there for 2 to 3 weeks.
The bump isn't the problem. Your skin is.
#2: Your Blood Thinner Turns Every Bump Into A Big Purple Stain
Eliquis. Xarelto. Warfarin. Plavix. Even a daily baby aspirin.
They protect your heart by slowing your clotting.
But when one of those exposed vessels breaks, it doesn't seal. It keeps leaking.
Bigger bruise. Darker bruise. Longer bruise.
And you can't stop your medication. So the only place left to fix this… is your skin.

#3: Everything You've Tried Was Never Made For Your Skin
You've probably tried at least three of these:
Arnica gelThin, watery, made for one sports bump. Does nothing for paper-thin skin.
Long sleevesHides it. Doesn't fix it. And the bruises keep coming.
Vitamin C pillsSwallowed, digested, barely reaches the skin on your arms.
MoisturizerSoftens the surface. Zero effect on the trapped purple blood.
"Just wait"Each bruise takes 2–3 weeks. A new one shows up before it's gone.
Stopping your medsDangerous. Never do this. Your heart needs it.
Here's the dirty secret: drugstore bruise products were made for a 25-year-old who bumped their knee playing tennis.
Not for thin, 70-year-old skin on a blood thinner that bruises every single day.
The bruise-product industry makes millions selling you the same thin gels over and over. Because if they actually fixed your skin… you'd stop buying.
#5: You'll See The Purple Fading In The First Week
Forearms, backs of hands, shins. Morning and night. 60 seconds.
Days 1–7: dark purple patches start breaking up and lightening.
Days 8–14: bruises fade dramatically faster than you're used to.
Weeks 3–5: skin feels thicker. New "mystery bruises" show up far less often.
After that: short sleeves are back.

What Happens If You Do Nothing
Today's purple patch becomes next month's three new ones.
This summer's long sleeves become every summer's long sleeves.
This year's family photos become the ones you hide your arms in.
⚠️ WARNING: thin skin doesn't just bruise. It tears. Seniors on blood thinners end up with painful skin tears from brushing against a door frame, and they take weeks to heal. The longer you wait, the thinner your skin gets.
Right now Onuva is running its biggest sale of the year. But it sells out every year before the holidays, when everyone wants their arms clear for the family photos.

Frequently Asked Questions
Is it safe if I'm on a blood thinner?
Yes. Onuva works on the skin, not your blood. You don't change anything about your Eliquis, Xarelto, warfarin, Plavix or aspirin. That's exactly who it was made for.
How fast will I see a difference?
Most people see existing purple spots start lightening in the first 7 days. By week 2 they're fading dramatically faster than usual, and by week 3–5 skin feels thicker and new bruises show up far less often.
How is this different from the arnica gel at the drugstore?
Drugstore gels are thin and made for one sports bruise on healthy skin. Onuva is a rich cream made for thin, aging skin, combining Vitamin K, Arnica and Calendula to clear the bruise AND strengthen the skin so new ones stop forming.
Will it stain my clothes or sheets?
No. It's non-greasy and soaks in within a minute, so you can get dressed right away.
How long does one jar last?
One 100 g jar lasts about 30 days using it morning and night on arms, hands and shins. That's why most people take the 2- or 3-jar plan.
What if it doesn't work for me?
