The fullness of the mons pubis and labia majora comes from a natural fat pad that sits just beneath the skin. Some people want more volume in this area for aesthetic reasons or because they’ve lost fullness due to aging, weight loss, or hormonal changes. There are several ways to increase volume, ranging from targeted lifestyle changes to cosmetic procedures.
What Determines Fullness in This Area
The mons pubis is a subcutaneous fat pad located directly over the pubic bone, and the labia majora are the two outer skin folds that extend from it. Both structures get their shape and cushioning primarily from fat tissue. How much fat naturally accumulates here varies widely from person to person, influenced by genetics, overall body fat percentage, hormone levels, and age.
Estrogen plays a major role in maintaining tissue volume throughout the vulvar area. As estrogen levels decline, particularly during and after menopause, tissues become thinner, drier, and less elastic. This is why many people notice a loss of fullness in the mons and labia as they age, even if their overall body weight stays the same. Smoking accelerates this process by reducing blood flow and blunting the effects of whatever estrogen the body does produce.
Weight Gain and Body Fat Distribution
The simplest way to add volume to the mons pubis and labia majora is to increase your overall body fat. Because these structures are fat pads, they respond to changes in body composition just like fat deposits elsewhere. Gaining weight through a caloric surplus will, over time, add some fullness to this area.
The catch is that you can’t choose where your body stores fat. Genetics determine whether extra calories end up primarily in your hips, abdomen, thighs, or pubic area. Some people notice the mons fills out relatively quickly with weight gain, while others store fat elsewhere first. There’s no specific food, exercise, or supplement that directs fat exclusively to the vulvar area, despite what some online sources claim.
Strength training for the lower body (squats, hip thrusts, lunges) won’t add fat to the mons, but it can change the overall proportions of the pelvic region in a way that makes the area appear fuller relative to the surrounding muscles. This is a subtle effect, but some people find it makes a noticeable difference.
Fat Transfer (Lipofilling)
Fat grafting is the most common surgical option for adding lasting volume. A surgeon removes fat from another part of your body, typically the abdomen or thighs, through liposuction, then processes and injects it into the mons pubis or labia majora. Because the injected material is your own tissue, there’s no risk of an allergic reaction, and the results look and feel natural.
The main limitation is that the body reabsorbs a portion of the transferred fat over the following months. Reabsorption is the most common complication of fat grafting procedures overall, occurring in roughly 62% of cases in one hospital analysis. Bruising follows at about 38%, with swelling in around 19% of patients. Infection is rare, and asymmetry occurs in about 5% of cases. Because some fat is reabsorbed, surgeons typically overfill slightly, and a second session is sometimes needed to reach the desired result.
In the United States, fat transfer to the labia majora and mons pubis typically costs between $1,500 and $6,000 depending on the provider, geographic location, and how much volume you’re adding.
Hyaluronic Acid Fillers
For a non-surgical option, injectable fillers can add volume to the labia majora and mons pubis in a single office visit. The most commonly used fillers for this area are based on hyaluronic acid, the same substance used in lip and cheek fillers. A typical session uses 3 to 5 cc of product, and the procedure takes under an hour.
The results are temporary. Hyaluronic acid fillers in the genital area are gradually absorbed by the body over roughly 9 to 12 months, at which point you’d need a repeat session to maintain the fullness. The cost for filler-based augmentation runs around $4,500 per session at specialized clinics, though prices vary. The advantage over fat transfer is a shorter procedure with less downtime, but the ongoing cost of repeat treatments adds up quickly.
Recovery After Cosmetic Procedures
Whether you choose fat grafting or fillers, expect some swelling, tenderness, and bruising in the days following treatment. Fillers generally involve less downtime, with most people returning to normal activities within a few days.
Fat transfer requires a longer recovery. Plan to avoid strenuous exercise, cycling, running, swimming, and sexual activity for four to six weeks. Returning to these activities too soon can put pressure on the treated area, disrupt healing, and compromise your results. Most swelling resolves within the first two weeks, but the final shape won’t be apparent until three to six months later, once the body has finished reabsorbing the portion of transferred fat it won’t keep.
Maintaining Tissue Health
Regardless of whether you pursue a procedure, a few habits help preserve the fullness and health of vulvar tissues over time. Regular sexual activity or masturbation promotes blood flow to the area, which helps keep the tissues healthy and elastic. Avoiding smoking is one of the most impactful things you can do, since reduced blood flow from cigarette use directly contributes to tissue thinning.
If you’re experiencing volume loss related to menopause or hormonal changes, a conversation with a gynecologist about topical estrogen may be worthwhile. While topical estrogen primarily addresses dryness and elasticity rather than adding significant fat volume, it can improve the overall texture and resilience of the tissue, which contributes to a fuller appearance.
