Why do I have chubby cheeks even if I’m slim?
Can facial fat actually be reduced?
A fuller or rounder face isn’t always caused by weight gain. Chubby cheeks can result from facial fat, enlarged masseter muscles, facial structure or skin laxity — and identifying the cause is important before considering treatment.
At Ai Beauty Clinic in London, we assess your facial anatomy and the reason for the fullness before recommending a treatment.

What causes chubby cheeks?
If your face looks round, wide or heavier around the cheeks and jawline, there are several possible causes.
Facial fat
Some people naturally store more subcutaneous fat in their cheeks and lower face. This can create a rounder or fuller appearance even when the rest of the body is relatively slim.
Enlarged masseter muscles
The masseter muscles sit at the sides of the jaw and are used for chewing. If they are particularly developed, they can make the lower face appear wider or more square.
Facial structure
Your cheekbones and jawbone have a major influence on the natural width and shape of your face. What appears to be excess facial fat may therefore partly be your underlying facial anatomy.
Ageing and skin laxity
As facial tissues change with age, the cheeks and lower face can begin to sag. This may make the lower face look heavier and reduce definition around the jawline.
Which treatment is right for me?
There is no single best treatment for every perioral mound.
During a consultation, the clinician will assess:
- whether the fullness is predominantly fat or loose tissue
- your skin quality and degree of laxity
- changes in the cheeks and lower face
- your facial anatomy
- whether treatment is appropriate and what result can realistically be achieved
You will then be advised on suitable options, expected results, potential risks and alternatives.

Enlarged Masseter (chewing muscle) type of chubby cheeks
Enlarged Masseter muscle can lead to a fat cheeks look. Frequently chewing gums or hard foods (e.g. betel nut) will enlarge the Masseter muscle. Playing musical instruments that require the constant contraction of Masseter muscle also has the same effect.


Symptoms
Chubby cheek – enlarged Masseter
Masseter muscle is located underneath the subcutaneous fat layer. You can check whether you have muscular Masseter muscles by gritting your teeth. If you see masseter muscles bulge out to the side of the face, you have enlarged Masseters muscles.
Sagging cheeks type
The loss of fat or collagen on the face leads to the reduction of facial support, appearance of wrinkles around the nose and mouth, sagging skin and the accumulation of saggy skin at the jawline.
