Understanding the Aging Mouth: 4 Core Changes
While lip fillers often promise quick fixes, they rarely address the deeper structural and anatomical changes that occur with age. To understand how to truly restore a natural-looking mouth, it helps to first look at the specific ways the area evolves over time.
01. Lip Elongation
One of the earliest and most significant changes is the elongation of the upper lip. In youth, the upper lip typically measures 13-15 mm, but after our late 40s to early 50s, this can lengthen to 18-22 mm. This elongation causes:
- A flatter smile
- Inversion of the red lip
- Loss of dental show (the visibility of your top teeth when smiling)
- Formation of a horizontal crease across the upper lip
02. Volume Loss in the Lower Face
Aging isn't just about losing lip volume. The entire perioral area (under the nose, around the lips, chin, and pre-jowl areas) undergoes fat loss and bone resorption in the jaw. This results in:
- Deflated lips
- Hollowing around the mouth and chin
- Loss of definition and support
03. Skin Creasing Around the Lips
The skin around the mouth thins and loses resilience. As the muscle around your mouth repeatedly contracts, it pulls this fragile skin inward, gradually etching deeper lines into the surface. This process contributes to:
- Vertical lip lines, often called "smoker's lines" (regardless of smoking history)
- Fine creases and deep wrinkles
- Crepey texture and skin laxity
04. Adjacent Structural Changes
Aging cheeks descend and crowd the mouth area, contributing to:
- Nasolabial folds (smile lines)
- Marionette lines (creases from corners of mouth to chin)
- Downturned mouth corners (due to muscle imbalances)
By rejuvenating this area, we restore not only youthful balance to your features but also the harmony between your appearance and your identity.

Dr. Karam,
I recently read your article on why lip lines are so difficult to treat, and it brought up a question regarding fat transfer longevity.
When I consulted with you before my vertical facelift in August 2023 my understanding was that the fat transfer to my face and hands would provide long-lasting, potentially lifetime, volume. I was very pleased with the facelift.
However, I have been disappointed with the loss of volume. Within about a year and a half, it seems that much of the transferred fat in my face and hands was gone. Since then, I have been trying to restore volume conservatively with PRF treatments rather than fillers. My temples have become hollow again, my lips have lost volume, and I am now seeing more vertical lip lines and volume loss around my mouth.
One thing I have not done is take any GLP-1 medications such as Ozempic or similar weight-loss drugs, so I do not believe medication-related weight loss contributed to the fat loss.
I also wanted to share some feedback regarding follow-up care. After surgery, I only had one virtual follow-up appointment. Given the investment I made in the procedure, I would have appreciated a six-month in-person evaluation or additional follow-up to assess the longevity of the fat transfer and discuss any concerns. The surgical result itself was excellent, but the follow-up experience left me feeling somewhat overlooked.
I am not writing to complain, but rather to better understand why the fat transfer may not have lasted as expected and whether this degree of volume loss is typical in your experience.
Thank you for your time, and I look forward to hearing your thoughts.

Hi Dr. Karam,
I’ve been watching your videos for a long time. I love how you break things down for us! I’m 63 years old and recently had a Halo Laser on my face. Oh dear God, it was so painful I wanted to jump off the chair and head for the door! My face swelled up like a monster! I was unrecognizable, literally, my iphone could not open. I wish someone told me the truth about it because I would have went a different route:(
I was hiding in the house for 2 weeks and would wear a baseball cap and sunglasses because of the bruising. Is this normal? Am I just super sensitive? I took Arnica pills, followed instructions to the T.

Hi MaryAnne—Thank you so much for watching the videos and sharing your experience. While swelling, redness, and downtime can absolutely happen after Halo — especially depending on settings, skin sensitivity, and individual healing response — it’s important that patients fully understand the potential recovery process beforehand. Some people do experience more significant swelling and downtime than others. We’re sorry it was such a difficult experience for you, but are glad you followed your aftercare instructions carefully and hope you’re healing well now.

I always had a very thin top lift and my bottom lip showed some red. I am now 71 and for the last few years have a completely inverted top and bottom lips. No red showing at all. I watched your video on how to improve a top lip but what can be done for a lower lip? I recently found an article on a technique referred to as a Brazilian Hug lip which, with fillers, would improve both top and bottom lips. Your thoughts please.

Hi Cathy—Thanks for your comment! Results can vary depending on individual anatomy. The best approach is a personalized consultation with a skilled injector who can evaluate your lips and recommend a treatment plan that balances natural results with your goals.

Hi DC Karma I am 52yr and 3 years ago I had a lower facelift and lip lift in Thailand. The lip lift was a disaster as he didn’t perform the bull lift he went around the top lip which has left me with horrible pucker lines from the stitches being pulled too tight and scaring and unevenness. it messes with my head everyday and I wonder if there is any treatment to help fix the issues. I have had fillers which do soften the lines and a little botox to prevent the “pulling” also RF and some laser treatment but I wonder if this may have made it worse as my skin is thin and not a lot of fat, so I am still unhappy with the results as the lines are so obvious. I just resign myself to the fact that I just have to live with it.
Bottom line is always do your research first and your channel certainly helps. :)
Is there any advice you can pass on to me?

Hi Robyn—Thanks for your comment! Because your concerns involve prior surgery, scarring, and thin skin, the safest next step is a consultation with a board-certified facial plastic surgeon who specializes in revisions. They can assess your skin and previous treatments and recommend the best way to soften the lines and improve symmetry. Wishing you the best in finding a solution that gives you more confidence, and we’re so glad to hear the channel has been helpful in guiding you along the way!
