I think it was a few years ago when I started hearing the advice to always use your ring finger when applying eye cream or concealer, as it is the weakest finger, and therefore would not drag at the delicate skin around the eyes. Almost everyone follows that advice now, but what’s the science behind it?
There are 2 questions that we can ask here:
1-Is the ring finger really the weakest finger?
No, but it depends on what task you are referring to. Are you gripping or pinching or pushing with your various fingers? Each finger contributes differently to a task depending on how it is used, and each finger is the strongest at certain tasks. Generally the thumb, index and middle fingers are more efficient in tasks that require precision, while the ring and small fingers are important supplements to a grip.
The ring finger might be considered weak because of this popular test: put your hand palm down on a table, then tuck all your fingers in to make a fist. If you try extending only your index finger you will find you can do it easily. Same thing with the little finger and somewhat with the middle finger. But if you tuck all these fingers back in and try extending your ring finger alone, you will have a lot of difficulty. This is not due to weakness per se, the ring finger is bound to the fingers around it with tendons that limit its movement. It is the most dependent finger. But in terms of strength, it has been found to be comparable to the index finger. In general, it is the small finger that is the weakest.
2-Is the ring finger weak enough to not harm the skin around the eyes?
It’s not about using the weakest finger, it’s about how you use that finger. Even our weakest finger is still strong enough to do damage if its not used carefully. Go to a mirror and pretend to apply a cream around your eyes using your small finger; if you use more than even a feathery touch and drag, your skin moves with your finger. Big no no!
So what should you do?
This is one of these posts that is simply meant to satisfy an inquisitive mind. When I hear “the ring finger is the weakest, so use it for eye cream application,” I want to investigate. So this is purely for anyone who ever wondered. In summary, the ring finger is not the weakest finger, and no finger is weak enough that it can’t harm the skin around the eyes if it wasn’t applied delicately enough.
Personally, I like using my ring finger for applying eye cream, simply because it feels more comfortable. All that matters is that you are always gentle with the skin around your eyes, and your entire face for that matter. No tugging. Pat pat pat away that cream!
