Breast reduction scars usually go through a predictable cycle: a fine closed line for the first few weeks, a pinker, firmer and sometimes raised phase between about six weeks and six months, and then gradual softening and fading until they mature at 12 to 18 months. Silicone gel or sheets, gentle massage once healed, sun protection and a supportive bra can all help. Scars that become thick or raised can be treated, and revision is possible once they have matured.
The first few weeks
Immediately after surgery, the incisions are closed with dissolvable stitches beneath the skin, often covered with glue or tape. Keep dressings clean and dry as instructed, and wear your supportive post-surgical bra day and night to reduce tension on the scars. A small scab or slow-healing area at the point where the vertical and horizontal scars meet is common and is usually managed with simple dressings at your follow-up visits. Avoid soaking in a bath or swimming until the wounds are fully healed.
Six weeks to six months
This is when scars often look their most obvious. Collagen is being laid down and the scar may become pink or red, slightly raised, firm and itchy. This is part of normal healing and does not predict how the scar will look in the long term. Continue to avoid heavy lifting and exercises that stretch the chest, as tension can widen the scar.
Six to eighteen months
Over this period, the redness usually fades and the scar flattens and softens. By 12 to 18 months most scars have matured into paler, finer lines, although some remain slightly wider or darker, particularly on darker skin tones or at the ends of the horizontal scar. Final judgement of scar quality should wait until this stage.
Scar care routine
- Silicone: once the wounds have closed, silicone gel or sheets applied daily for several months are widely recommended to help scars flatten and soften.
- Massage: gentle massage with a plain, unperfumed moisturiser, a few minutes each day, can reduce tightness.
- Sun protection: keep scars covered or use a high-factor sunscreen for at least a year, as sunlight can darken them permanently.
- Support: a well-fitting, non-wired bra reduces pull on the lower scars in the early months.
- No smoking: nicotine impairs healing and can worsen scars.
Your nurse or surgeon will tell you when to start each step.
Signs that need attention
Contact the team the same day if a scar opens, weeps, becomes increasingly red, hot or painful, or if you develop a fever. If one breast suddenly swells and becomes tense, contact the surgical team urgently. Later, if a scar becomes progressively thicker, very itchy, or grows beyond the original incision, it may be a hypertrophic or keloid scar, and early review is helpful.
Options for poor scars
Raised scars may respond to silicone, pressure and steroid injections. Once fully mature, a wide or uneven scar can be improved with scar revision, and small dog-ears at the ends of the horizontal scar can often be corrected under local anaesthetic. If there is also a shape concern, see our revision breast reduction guide. Revision is usually delayed until at least a year after surgery.
Factors that influence your scars
Scar quality depends partly on things you can influence and partly on things you cannot. Genetics and skin type play a large role: some people form fine, pale scars easily, while others are prone to thicker scars regardless of care. Tension matters, which is why larger reductions, heavier remaining breasts and early strenuous activity can widen scars. Wound infection or delayed healing can also leave a broader scar. Not smoking, keeping to a stable weight and following aftercare advice give your scars the best opportunity to settle well.
Living with your scars
Most women find that the scars become much less noticeable with time and are covered by bras and swimwear. It can take time to feel comfortable with the new appearance, and it is normal to have mixed feelings in the early months. Talking to the team at follow-up can help. Breast reduction costs from £11,500 and the £150 consultation fee is separate. Surgery is for adults aged 18 and over.
Frequently Asked Questions
When can silicone be used on breast reduction scars?
Once the wounds have fully closed and any scabs have gone, usually two to three weeks after surgery, unless your team advises otherwise.
Why are the scars redder at three months than at three weeks?
Scars often become more noticeable in the first few months as collagen builds up. They usually fade and flatten afterwards.
Do breast reduction scars ever disappear?
No, but most fade into pale, flat lines by 12 to 18 months.
Can raised scars be treated?
Yes. Silicone, pressure and steroid injections can help, and scar revision may be considered once the scar has matured.
