Top surgery scars depend mainly on the technique. Double incision, the most common approach and the one used for medium to larger chests, leaves two horizontal scars along the lower chest; keyhole and periareolar methods, used for smaller chests with good skin elasticity, leave much smaller scars around the areola. Most scars start red or pink and slightly raised, then flatten and fade over roughly 12 to 18 months. Surgical technique, consistent scar care, sun protection and your own genetics all shape the final look. Scars never disappear entirely, but for most people they settle to fine, pale lines.
What determines your top surgery scars
Three things shape how your scars end up. The first and biggest is the surgical technique, which is chosen mainly around your chest size and skin elasticity. The second is how you heal, which is partly genetic; some people scar flatter and paler than others, and skin tone affects how scars pigment. The third is aftercare, which is the part you can influence: protecting the scars, using evidence-based scar treatments and avoiding tension on the healing lines all help.
It helps to set expectations honestly from the start. Every top surgery leaves a scar, and the goal is not an invisible chest but a flat, masculine one with scars that fade into fine lines you stop noticing. Many trans men and transmasculine people find the scars become a non-issue, or even something they feel neutral or positive about, once they have healed and the chest feels like their own.
Top surgery scars by technique
The approach your surgeon recommends is driven by anatomy, not preference alone. This is the single biggest determinant of your scars.
| Technique | Suits | Scar pattern |
|---|---|---|
| Double incision with free nipple grafts | Medium to larger chests, or looser skin | Two horizontal scars along the lower chest, below the pectoral line, plus a fine line around each resized, repositioned nipple. Gives the flattest, most reliable result. |
| Periareolar (donut) | Smaller chests with good skin elasticity | A circular scar around the edge of the areola only, so scarring is limited and well camouflaged at the areola border. |
| Keyhole | Small chests, minimal excess skin, good elasticity | A small scar at the lower edge of the areola, the least scarring of the three. The nipple usually keeps its original attachment and sensation. |
The trade-off
Smaller-scar techniques are appealing, but they only work when there is little skin to remove and the skin will re-drape well. Choosing keyhole or periareolar for a chest that really needs double incision tends to give a poorer contour that is harder to fix later. A good surgeon will be honest about which technique your chest calls for, even if it is not the one with the smallest scars. Our guide to FTM top surgery cost and our FTM surgery in Thailand page explain how the techniques are matched to you.
How top surgery scars heal: a timeline
Scars change a great deal over the first year, and knowing the pattern makes the early, angry-looking stage far less worrying. This is a general guide; your surgeon’s guidance comes first.
- Weeks 0 to 2. Incisions are closed and healing; you wear a compression binder and follow wound-care instructions. Grafted nipples go through a scab-and-heal phase that looks alarming but is normal.
- Weeks 2 to 6. The wounds are closed but the scars are new. This is when most people can return to desk work and start to see the chest shape emerge under residual swelling.
- Months 1 to 3. Scars typically look their worst here: red or dark, firm and sometimes raised or itchy. This is expected and usually the point at which silicone and other scar care matter most.
- Months 3 to 12. Scars gradually flatten, soften and lose their colour. Itch settles. The chest contour finalises as the last swelling goes.
- 12 to 18 months. Scars reach their mature state: usually flat, pale, fine lines. This is the point to judge the final result and consider any minor revision.
Scar care that actually helps
Plenty of products are marketed for scars, but only a few approaches have good evidence behind them, and timing matters. Always follow your own surgeon’s protocol, but the mainstays are:
- Silicone. Silicone sheets or gel are the most evidence-backed over-the-counter scar treatment, used once the wounds are fully closed and typically continued for a couple of months. They help scars flatten and fade.
- Sun protection. New scars pigment easily and can darken permanently if sunburned. Keep them covered or use high-factor sunscreen once healed, for at least the first year.
- Scar massage. Once your surgeon clears it, gentle massage can help soften and flatten scar tissue and reduce tightness.
- Avoiding tension. Following activity restrictions and wearing your binder as directed keeps tension off the healing lines, which is one of the biggest factors in how wide a scar ends up.
- General healing. Not smoking, eating well and staying hydrated all support better wound healing and, in turn, better scars.
What does not help is starting treatments too early on open wounds, or expecting any cream to erase a scar. The realistic aim is to help your scars settle to the best version of themselves.
When top surgery scars need attention
Some scar changes are normal and some are worth flagging. It helps to know the difference.
Hypertrophic scars are raised, red and sometimes itchy, but stay within the line of the original incision. They are common in the first months and often improve with silicone, massage and time; a surgeon can add treatments such as steroid injections if needed. Keloid scars grow beyond the original incision and are firmer and more persistent. They are less common and more likely in people with a personal or family history, which is worth mentioning before surgery so your surgeon can plan for it.
Separately, contact your surgical team promptly if a scar becomes increasingly red, hot, swollen, painful or starts to open or discharge, as that points to a healing problem rather than normal scarring. While you are in Thailand we help you reach the team quickly if anything worries you.
Scar revision, dog-ears and nipple tattooing
Once everything has matured, usually after twelve to eighteen months, a few refinements are possible. Dog-ears, the small puckers that can form at the ends of double-incision scars, can be trimmed in a minor procedure. A scar revision can improve a scar that has healed wider or more raised than hoped. And nipple tattooing (medical micropigmentation) can restore colour and definition to grafted nipples, or recreate a nipple entirely, which many people find completes the result.
None of these is essential, and many people are happy without them. They are options to know about, not steps you are expected to take.
How the nipples and their scars heal
For many people the nipples matter as much as the chest scars, and how they heal depends on the technique. With double incision and free nipple grafts, the nipples are removed, resized and grafted back onto the reshaped chest. They go through a healing phase over the first couple of weeks that can look worrying, scabbing, darkening and sometimes partially lightening, before settling. There is a fine scar around each grafted nipple, and sensation in the nipple itself is usually reduced or lost, though the surrounding chest often regains feeling over the following months.
With keyhole and periareolar techniques, the nipple usually keeps its original blood supply and nerve attachment, so erogenous sensation is more often preserved and scarring is limited to the areolar border. This is one of the reasons these techniques are appealing when a person’s chest suits them, though they remain options only for smaller chests with good skin elasticity.
Whichever route you have, the nipple result keeps refining over the first year. If a grafted nipple heals paler than you would like, or you want more definition, medical nipple tattooing later can restore colour and dimension, and some people choose it to complete the look. Occasionally a small part of a graft does not fully take and needs a minor touch-up, which your surgeon manages. As with the chest scars, protecting the area from the sun and following your aftercare gives the nipples the best chance of settling well.
Living with the scars
It is worth saying that scars are only one part of the picture, and for most trans men and transmasculine people they matter far less after healing than they expect beforehand. Once the chest is flat and feels like their own, many find the scars fade into the background of daily life, become something they feel neutral about, or even wear as a marker of a step that mattered to them. There is no single right way to feel about them.
If your scars do bother you as they heal, the steps in this guide, silicone, sun protection, massage and time, are the practical levers, and a revision remains an option once everything has matured. What tends not to help is judging the result too early, while the scars are still in their red, raised phase. Give them the full year to eighteen months to show you what they will actually become.
