As a teenage girl grows taller and heavier, she also experiences growth in the bones of the face. These changes are less dramatic than they are in boys, but they do change appearance as the face becomes longer and more angular. The first extension is from the ridge of the nose down to the mouth.
Studies have shown that by the age of 35, the natural aging process causes us to lose about 10% of the fat in our faces, and we lose an additional 5-10% of your facial volume every 5-10 years thereafter.
Researchers have found that the number of fat cells in your body is set during adolescence and remains constant through adulthood, regardless of whether you gain or lose weight. The findings may help to explain why it can be so hard for some people to drop pounds and keep them off.
Rather than focus on losing excess fat from your face specifically, it's best to focus on overall fat loss and weight loss. When you lose weight overall, you'll lose it from your face too.
Just like some people carry extra weight in their hips, some people carry it in their face. In general, facial fat tends to be more noticeable in people with rounded, less-pronounced facial features. Additionally, your diet can also contribute to weight gain in the face.
If you're eating fewer calories than you're burning, you'll experience fat loss in all parts of your body, including your face. Your face may appear more gaunt on days when you're more dehydrated. Research has also linked high sugar diets to premature facial aging due to its negative effects on collagen and elastin.
Body shape – Another sign of puberty in girls is changing body shape, particularly extra fat in the belly area (some call it “baby fat”). Weight gain can cause anxiety for girls. This is part of normal development, and her body will redistribute the fat from the stomach and waist to the breast and hips.
Noticeable weight gain may occur prior to a growth spurt as excess fat helps promote growth. As a child goes through puberty, their stores of body fat may change. For example, girls tend to gain more fatty tissue in the hips, thighs and buttocks, while boys may have an increase in fat on their stomachs.
Puberty. Hormones released during this time often cause boys to gain muscle and girls to experience an increase in body fat. These changes are normal, but they may make you feel like you're overweight, even if you're not.
If extra fat "is present in early adolescence (taken here as age 11), it is highly likely to persist," the researchers write. In other words, preteens' "baby fat" (which the British researchers call "puppy fat") tended to last into the teen years.
After the age of 13 years, the facial growth slowed down, and after 16 years of age it practically ceased. Bulygina et al.  also reported a significant decline in the rate of growth at approximately 13 years of age and a cessation of growth at about 15 years of age.
If you have a rounder face due to being overweight, the easiest way to slim down your face is to lose fat from your entire body. You can do this by being in a calorie deficit – eating fewer kcals than you need, or burning more kcals than you use through exercise (or a combination of both).
Another thing that comes with puberty is acne, or pimples. Acne is triggered by puberty hormones. Pimples usually start around the beginning of puberty and can stick around during adolescence (the teen years). You may notice pimples on your face, your upper back, or your upper chest.
Generally, the jaw will grow in proportion with the rest of the face, with the greatest growth during puberty. If you have a tendency towards a small jaw this proportion usually does not change.
Skin becomes loose and sagging, bones lose their mass, and muscles lose their strength as a result of time spent living life. Most people begin to notice a shift in the appearance of their face around their 40's and 50's, with some also noticing a change in their 30's.
Hi, it's not unusual for the face to have "baby fat" through the teens into the early twenties. Faces can have more or less fat just like other areas of the body. At 19 years of age, it's reasonable for you to wait and see how much baby fat will be lost as you age.
If a 13-year-old girl weighs under the fifth percentile, a doctor may classify this as being underweight. If a 13-year-old girl weighs above the 95th percentile, the doctor may diagnose obesity.
You'll probably gain weight in puberty -- most girls do. You may notice more body fat along the upper arms, thighs, and upper back. Your hips will grow rounder and wider; your waist will become narrower.
The reason behind excess face fat is poor diet, lack of exercise, aging, or genetic conditions. Fat is usually more visible in the cheeks, jowls, under the chin, and neck. Facial fat tends to be more noticeable in people with rounded, less-pronounced facial features.
What is runner's face? If you haven't heard the term, you've likely seen it. It is the face of a lifelong runner with leathery, saggy skin and a gaunt appearance. It is the result of lots of sun exposure and little body fat.
Chewing gum does not reduce face fat.
It is a popularised myth that chewing gum reduces face fat. The simple fact is that you cannot reduce fat from one spot. Chewing gum can give your facial muscles a good workout but isn't effective in reducing face fat.
Overall Weight Loss:
Face fat is often the result of excessive accumulation of body fat giving you a fuller puffier appearance. Regular workouts and adding cardio to the routine can promote overall weight loss, improve body metabolism and show effective results in slimming down both the face and body.
Foods you should avoid
Often processed foods are packed with ingredients that "could cause weight gain, water retention, and inflammation—such as added sodium, refined carbohydrates and sugars, and trans fats," says Poon. So if you're looking to reduce puffiness, best to steer clear of highly processed foods.
