Gynaecomastia is the enlargement of male breast tissue. It may affect one or both sides of the chest and can occur during puberty, adulthood or later life.
Although commonly described as “man boobs”, an enlarged male chest can have several different causes. It may be due to:
- Firm glandular breast tissue
- Localised chest fat, known as pseudogynaecomastia
- Loose or stretched skin
- Enlargement of the nipple and areola
- A combination of gland, fat and skin laxity
Gynaecomastia is usually benign, but adult-onset or unexplained chest enlargement should be properly assessed before cosmetic treatment. Clinical guidelines recommend distinguishing true glandular gynaecomastia from fatty pseudogynaecomastia and considering underlying hormonal, medication-related or medical causes.
At Skin and Scar Care Clinic, we provide a medically led assessment to identify the likely cause of male chest enlargement.
For carefully selected patients whose concern is mainly caused by localised fat and mild skin laxity, we may recommend minimally invasive treatments such as Endolift® to reduce superficial fatty tissue, stimulate collagen and improve chest definition.
Where firm glandular enlargement, a suspicious lump or an underlying medical condition is suspected, we will recommend appropriate GP assessment, investigation or referral. Long-standing glandular gynaecomastia often requires surgical gland removal, sometimes combined with liposuction, for a predictable result.
What Is the Difference Between Gynaecomastia and Pseudogynaecomastia?
True Gynaecomastia
True gynaecomastia is caused by benign growth of glandular breast tissue. It commonly presents as a firm or rubbery disc of tissue beneath or around the nipple and areola.
It may be associated with:
- Tenderness or sensitivity
- Puffy or enlarged nipples
- Firm tissue beneath the nipple
- Asymmetry between the two sides
- Increased areolar diameter
- Enlargement that does not respond to weight loss
Endolift®, cryolipolysis and other fat-reduction treatments cannot reliably remove a substantial, established glandular mass. Patients with long-standing or fibrotic glandular gynaecomastia may require assessment for surgical gland excision. Current clinical guidelines regard surgery as the treatment of choice for persistent, long-standing gynaecomastia where spontaneous regression or treatment of an underlying cause has not resolved the problem.
Pseudogynaecomastia
Pseudogynaecomastia, also called lipomastia, is enlargement of the male chest caused mainly by excess fatty tissue rather than glandular growth.
The tissue is generally:
- Softer and more diffuse
- More easily pinched
- Spread across the chest rather than concentrated beneath the nipple
- Associated with general weight gain or localised fat distribution
- More likely to respond to weight loss or fat-reduction treatment
Pseudogynaecomastia is the form most likely to be considered for non-surgical or minimally invasive body-contouring treatment.
Combined Gynaecomastia
Many patients have a combination of:
- Central glandular tissue beneath the nipple
- Peripheral fatty tissue
- Enlarged or puffy areolae
- Mild or moderate loose skin
Pseudogynaecomastia is the form most likely to be considered for non-surgical or minimally invasive body-contouring treatment.
What Causes Gynaecomastia?
Hormonal Changes
Male breast tissue is influenced by the balance between androgen and oestrogen activity. Changes in this balance can stimulate glandular breast development.
Physiological gynaecomastia is particularly common during:
- The newborn period
- Puberty
- Later adult life
Pubertal gynaecomastia frequently improves spontaneously, whereas new adult-onset gynaecomastia may require more detailed assessment.
Excess Body Fat
An increase in body fat can produce a fuller male chest. Fatty tissue may also increase the conversion of androgens into oestrogen, potentially contributing to both pseudogynaecomastia and true glandular enlargement.
Weight reduction may improve fatty chest enlargement but may not remove established glandular tissue.
Natural Ageing
Ageing may be associated with:
You may not be suitable if you:
- Hormonal changes
- Reduced testosterone activity
- Loss of chest muscle mass
- Increased central fat distribution
- Reduced skin elasticity
- Lower nipple position
- Loose or folded chest skin
These changes can make the chest appear softer and less defined.
Anabolic Steroid Use
Anabolic steroids can disrupt the balance between androgen and oestrogen activity and may cause persistent glandular enlargement.
Patients should disclose current or previous anabolic steroid and hormone use during consultation, as this may affect diagnosis, treatment selection and the risk of recurrence.
Underlying Medical Conditions
Gynaecomastia may occasionally be associated with:
- Testosterone deficiency
- Thyroid disease
- Liver disease
- Kidney disease
- Testicular disorders
- Pituitary or other endocrine conditions
- Hormone-producing tumours
- Malnutrition or significant systemic illness
Guidelines advise that adult gynaecomastia should be assessed for potentially reversible or pathological causes. Depending on the clinical findings, investigations may include hormone tests and liver, kidney or thyroid-function testing.
Genetics and Natural Fat Distribution
Some men naturally store more fat around the chest, lateral chest wall and armpits despite having a healthy weight.
Genetics may also influence:
- Skin elasticity
- Chest shape
- Areolar size
- Fat distribution
- Response to weight loss
Significant Weight Loss
Following substantial weight loss, the fatty volume of the chest may reduce while stretched skin remains.
This can cause:
- Loose chest skin
- Lower nipple position
- Creases beneath the breast
- Residual lateral chest rolls
- An empty or deflated appearance
Minimally invasive tightening may improve mild laxity, but significant excess skin may require a surgical male chest lift.
When Should You See Your GP?
A medical assessment is recommended before aesthetic treatment where chest enlargement is new, unexplained, painful or asymmetrical.
You should seek medical advice if you notice:
- A new or rapidly enlarging lump
- A hard or irregular mass
- Persistent pain or tenderness
- Enlargement affecting only one side
- Nipple discharge or bleeding
- Nipple inversion
- Skin dimpling, redness or ulceration
- Enlarged lymph nodes in the armpit
- A testicular lump, pain or swelling
- Unexplained weight loss
- Other symptoms of hormonal or systemic illness
The NHS advises seeing a GP for a persistent breast or nipple lump, pain, nipple discharge, bleeding or changes in the overlying skin.
Aesthetic treatment should not proceed until any suspicious or unexplained finding has been appropriately investigated.
Conditions We May Treat
Following appropriate assessment, our male chest-contouring treatments may be considered for:
- Pseudogynaecomastia
- Localised fatty male chest enlargement
- Mild or moderate chest fullness
- Poor chest definition
- Small pockets of fat around the outer chest
- Fat extending towards the armpits
- Mild chest skin laxity
- Crepey chest skin
- Loose skin following moderate weight loss
- Mild post-liposuction contour irregularities
- Residual fat following previous chest treatment
Endolift® is not routinely presented as a replacement for gland excision where a firm, substantial glandular component is present.
Comprehensive Male Chest Assessment
Before recommending treatment, we assess:
- When the enlargement began
- Whether one or both sides are affected
- Whether the tissue is fatty, glandular or mixed
- The location and firmness of any central tissue
- The amount of loose skin
- Nipple and areolar position
- Chest-muscle development
- Current weight and weight stability
- Medication and supplement use
- Previous anabolic steroid or hormone use
- Relevant medical history
- Previous surgery or liposuction
- The presence of pain, discharge or skin changes
Breast imaging or further medical assessment may be recommended when examination is uncertain. Suspicious findings require appropriate imaging or tissue diagnosis rather than cosmetic treatment.
Endolift® for Male Chest Fat and Pseudogynaecomastia
Endolift® and fractional CO₂ laser work at different tissue levels.
- Endolift® is used beneath the skin to address selected fatty tissue and deeper laxity.
- Fractional CO₂ laser works through the surface to improve texture and stimulate dermal collagen remodelling.
A combination may be considered where a patient has both:
- Fatty chest fullness
- Mild loose or crepey skin
- Stretch marks
- Fine surface wrinkling
- Uneven texture
- Selected scars from previous surgery or treatment
What Does CO₂ Laser Add?
Fractional CO₂ laser may help to:
- Improve crepey chest skin
- Stimulate surface collagen remodelling
- Refine fine lines
- Improve selected stretch marks
- Improve certain surgical or acne scars
- Smooth mild surface irregularities
- Improve the texture of the skin after deeper contouring
Fractional CO₂ treatment can produce measurable skin tightening through collagen remodelling, but evidence specific to male chest laxity following gynaecomastia remains limited. It should therefore be regarded as a skin-quality and surface-tightening treatment rather than a primary treatment for fat or glandular tissue.
Can Endolift® and CO₂ Laser Be Performed Together?
In carefully selected patients, the treatments may be performed during the same treatment episode.
Staged treatment may be preferable where:
- A larger chest area requires treatment
- Significant swelling is expected
- Stronger CO₂ settings are planned
- There is a history of pigmentation
- The patient has a darker skin type
- There are existing surgical scars
- The skin requires additional healing time
- The patient is prone to abnormal scarring
The chest can be more susceptible to hypertrophic and keloid scarring than some facial areas. Conservative settings, careful selection and strict aftercare are therefore essential.
Who May Not Be Suitable for CO₂ Laser?
Fractional CO₂ treatment may not be recommended where there is:
- Active bacterial, viral or fungal infection
- Open wounds or dermatitis
- Recent significant sun exposure or tanning
- A strong history of keloid scarring
- Poor wound healing
- Uncontrolled diabetes
- Immunosuppression
- Significant bleeding risk
- An unstable skin condition
- Inability to follow wound care and sun protection
- A suspicious lesion within the treatment area
Patients with darker skin tones may have a greater risk of post-inflammatory hyperpigmentation and require carefully adjusted treatment settings.
Endolift® Combined With Fractional CO₂ Laser
Endolift® is a minimally invasive laser-assisted procedure performed beneath the skin using a fine optical fibre.
The laser energy is delivered within selected subcutaneous tissue to:
- Target small or moderate superficial fat deposits
- Stimulate tissue contraction
- Promote collagen remodelling
- Improve mild skin laxity
- Refine chest contours
- Improve the transition between the chest and lateral chest wall
Endolift® may be particularly useful where the enlargement is mainly caused by soft fatty tissue accompanied by mild or moderate skin laxity.
What Can Endolift® Improve?
In suitable patients, Endolift® may help to improve:
- Fatty pseudogynaecomastia
- Mild male breast fullness
- Poor definition around the lower chest
- Fat extending towards the armpits
- Mild loose skin after weight reduction
- Reduced skin contraction following previous fat loss
- Minor chest contour irregularities
- Early age-related loss of chest firmness
Who May Be Suitable for Chest Endolift®?
Suitable patients commonly have:
- Soft and pinchable chest fat
- Minimal or no firm gland beneath the nipple
- Mild or moderate pseudogynaecomastia
- Mild to moderate skin laxity
- Stable body weight
- Good general health
- Realistic expectations
- No suspicious breast symptoms
- A preference for minimally invasive treatment
- An understanding that further treatment may be necessary
Who May Not Be Suitable?
Endolift® may not be appropriate where there is:
- A substantial firm glandular mass
- Severe or advanced gynaecomastia
- Significant nipple or breast drooping
- A large amount of excess chest skin
- A suspicious or unexplained breast lump
- Nipple discharge or bleeding
- Untreated endocrine or systemic disease
- Active infection or broken skin
- Uncontrolled diabetes
- A significant bleeding disorder
- Anticoagulant medication that cannot be safely managed
- Poor wound healing
- Pregnancy or breastfeeding
- Unstable body weight
- Severe obesity requiring broader weight management
- Unrealistic expectations
What Endolift® Cannot Do
Endolift® cannot reliably:
- Remove a large or fibrotic gland
- Correct severe nipple drooping
- Remove a significant fold of excess skin
- Treat an underlying hormonal disorder
- Replace a necessary medical investigation
- Provide the same degree of volume reduction as surgical liposuction or gland excision
Where significant glandular tissue is present, surgical removal remains the more established treatment.
Recommended Treatments
Fat Dissolving Injections (Suitable Patients Only)
For patients whose enlarged chest is primarily due to localised fat rather than glandular tissue, fat dissolving injections may help reduce unwanted fat deposits and improve chest contours. Suitability is determined following a comprehensive clinical assessment.
Body Contouring Treatments
Non-surgical body contouring treatments can target stubborn fatty deposits in the chest, helping to create a flatter and more defined masculine appearance. These treatments are most effective for carefully selected patients who are close to their ideal body weight.
RF Microneedling
If mild skin laxity is present following fat reduction, RF Microneedling can stimulate collagen production, improving skin firmness and helping the chest appear smoother and tighter.
Lifestyle & Weight Management Support
For many patients, maintaining a healthy weight, regular strength training, and balanced nutrition can complement aesthetic treatments and help preserve long-term results. Where appropriate, we will advise on lifestyle measures that support chest contouring.

Disclaimer
Jowl and jawline laxity treatments are medical aesthetic treatments and results vary between individuals. Treatment outcomes cannot be guaranteed.
Prominent jowls and jawline skin laxity may be caused by ageing, collagen loss, skin laxity, facial fat, volume loss, weight loss, menopause, muscle pull, bone support changes, genetics, sun damage or previous aesthetic treatments. A consultation is required to assess the true cause.
Endolift®, HIFU, CO₂ laser, Erbium Glass laser, Bio Remodelling / Bio Stimulator, Bio Remodelling / Bio Stimulator Structura, biostimulators, dermal filler and anti-wrinkle injections can improve selected cases of mild to moderate jowls, lower-face laxity, wrinkles and jawline concerns, but they do not guarantee complete correction.
Endolift® is not an alternative to a surgical facelift or neck lift. HIFU is suitable only for selected mild cases and may not be appropriate where there is significant heaviness, advanced laxity, very thin facial tissue or unrealistic expectations. CO₂ laser improves wrinkles, crepey skin and skin texture, but it does not replace lifting procedures where significant tissue descent is present.
Possible side effects include redness, swelling, bruising, tenderness, numbness, tightness, asymmetry, lumpiness, burns, pigmentation change, infection, delayed healing, scarring, incomplete improvement and the possible need for further treatment.
Rare but serious complications can occur with any medical aesthetic treatment. Please seek urgent medical advice if you experience severe pain, increasing swelling, skin colour change, signs of infection, visual symptoms or any concerning symptoms after treatment.
We always aim to provide 100% effort, but final results depend on anatomy, skin quality, degree of laxity, age, weight stability, collagen response, medical history, healing ability, lifestyle factors and adherence to aftercare.
