Everything You Need to Know

Aging is a natural process that causes unavoidable changes to your lips. Why do lips thin with age? Let’s find out the science behind the loss of lip volume and how you can handle the problem with the help of dermal fillers in Los Angeles.


Lips get smaller with age because the muscles in the area perioral (the area around the lips) experience thinning and stretching. This happens because your body’s collagen production slows, causing the lips to lose their plumpness. In addition, the fat cells in your lips also experience a gradual decline.
The result?
Smaller, thinner lips that have seen better days.
Aside from volume loss, aging can cause the lip borders—also known as the vermillion borders—and the Cupid’s bow (the upper middle part) to become less defined, flattened, or deformed. Thankfully, even age-induced volume loss in the lips does not mean the end of the road for you. You can both define and restore volume in your thin lips with fillers.

Granted, you have no control over lips getting smaller with age, but you can decide to get them enhanced with fillers. In addition to the natural process of aging, genetics, lifestyle habits like smoking, and even prolonged exposure to the sun can contribute to volume loss in your lips.
You can choose to undergo lip augmentation in Los Angeles to reverse the signs of aging. While it’s nearly impossible to stall the body’s natural process, aesthetic procedures are designed to improve age-induced signs on your face.
In fact, when administered by an experienced medical professional, lip fillers can make you more confident about your appearance and restore youthful plumpness to your face. Even those born with naturally thin lips can greatly benefit from lip fillers.
As long as you undergo treatment at a reliable medical spa in Los Angeles, you can look and feel great. Lip fillers for thin lips are very effective.
If you are keen on learning more about lip injections on thin lips, irrespective of age, find out what really happens when you undergo treatment.
A lip filler is a type of dermal filler made from lab-made versions of naturally occurring substances. It comes in many variations but shares the same working principle. Before the procedure, a topical numbing cream will be applied on your lips to reduce the sensation in the treatment area. Then, your medical professional will inject a hyaluronic-based dermal filler into your lips.

Fillers can be injected in any or some of the following areas:
01 Cupid’s Bow or the prominent curve in the center of your upper lip
02 The borders / edges of your lips
03 The corners of your mouth
04 Into the lips
In most cases, about 1 ml of filler is injected into the lips at one time. You may feel a gentle prickling sensation but, for the most part, the procedure is painless. This is an outpatient procedure and usually lasts for approximately 30 minutes.
You may be given ice packs to dull any sensation of discomfort and your provider may even massage your lips to facilitate faster absorption of the filler.
Temporary swelling and bruising is a common aftereffect of lip fillers but any discomfort should subside in the subsequent 24-48-hour period. In rare cases, it may take up to one week for all side effects to disappear.
When enhancing thin lips with filler, you can choose between hyaluronic acid-containing dermal fillers from various brands, such as Juvederm, Kysse, Refyne, RHA2, Versa etc. The results are similar and can last anywhere from 8 to 12 months.
Hyaluronic acid-based fillers are the safest because they are the least likely to cause any adverse reactions in your body, and are reversible. They come in many variations, available under their more commonly known brand name. We will discuss them below to give you clarity over which filler and treatment you should choose for your lips:
Juvederm is a hyaluronic acid-based lip filler. It comes in multiple varieties and can be used to add volume to age-induced thinning in lips. Besides, Juvederm fillers are also effective in adding definition and reducing signs of aging from the lips.
The Juvederm range comprises:
01 Juvederm Ultra XC: Ideal for enhancing super thin lips with filler. Adds plumpness, corrects any asymmetry, contours, and reduces wrinkles. So, if you’ve ever wondered, “Does lip filler help with lip wrinkles?”, check out Juvederm Ultra XC.
02 Juvederm Ultra Plus XC: Works the same as the Ultra XC but gives more long lasting results.
Consult an experienced medical professional before undergoing Juvederm filler treatment to ensure it’s the perfect match for your requirements.
Restylane also uses hyaluronic acid as the star ingredient of lip filler on thin lips. However, it does have a grainier texture compared to Juvederm, which gets easily absorbed into the body. It has the following variations:
01 Restylane Kysse: Ideal for a significant increase in lip volume. Gives a natural-looking outcome.
02 Restylane Refyne: Ideal for adding definition and volume to lips that get smaller with age. Gives a flawless finish.
