The three interventions with real evidence, and how long each needs to be continued.
Scar care is a field crowded with creams, oils and promises. Strip away the marketing and three interventions have consistent evidence behind them: silicone, massage and sun protection. Done properly, and for long enough, they change how most scars mature. Everything else is optional.
A fresh scar is a construction site. For the first three months it is red, raised and firm as the body lays down collagen; over six to twelve months it remodels, softens and fades. Scar care does not erase a scar, nothing does, but it steers this maturation so the final scar is flat, pale and supple rather than thick and dark.
Silicone gel or silicone sheets, applied daily to a fully closed wound, are the best evidenced scar treatment available. Start once the wound has completely healed, usually two to three weeks after surgery, and continue daily for three to six months. Sheets work well on flat areas and overnight; gel suits the face, joints and areas clothing rubs. Consistency beats brand; the cheapest silicone used daily outperforms the most expensive used occasionally.
Firm massage of the scar, enough to blanch it, for a few minutes several times a day, softens the collagen and frees the scar from the tissue beneath. Use any bland moisturiser to reduce friction. Massage also desensitises scars that are ticklish, tender or hypersensitive, which is common after hand surgery.
An immature scar exposed to sun darkens, and that pigmentation is often permanent. For the first year, keep the scar covered or under a broad spectrum sunscreen whenever it will see daylight. In practice this single habit makes more visible difference than any cream, particularly on the face and forearms.
Vitamin E, onion extract gels and most herbal preparations have weak or conflicting evidence; they are unlikely to harm, but they should never replace the three basics. Micro needling, laser and steroid injections have real roles, in the right scar, chosen by someone who treats scars, not from a shelf.
A scar that stays thick, raised, itchy or painful beyond three months may be hypertrophic or an early keloid, and early treatment changes the outcome. A scar that restricts movement, pulls an eyelid or lip, or keeps cracking open needs surgical review at any stage. And any scar can be revised once mature, usually after nine to twelve months, if its position or width justifies it.
Once the wound has fully closed, usually two to three weeks after surgery, and continued daily for several months while the scar is active.
Most have little evidence. Silicone, massage and sun protection are the three interventions that consistently help, and they cost less than most creams.
If it stays thick, raised, itchy or painful beyond three months, or if it restricts movement or distorts a feature at any time. Early review widens the options.
Most scars continue to soften, flatten and fade for up to a year and sometimes longer, which is why judgement about revision is not made early. Redness and firmness in the first months are usually part of normal maturing.
Yes, a new scar pigments easily, and darkening from sun exposure can be long lasting. Keep the scar covered or use sun protection on it for the first year.
Once the wound is fully closed, regular firm massage with a simple moisturiser helps keep the scar supple and is often advised alongside silicone. Start only when you have been told the wound is ready.
Pressure is used mainly for raised or burn related scars, over large areas, rather than for a narrow flat scar. Whether it is worth the effort in your case is a judgement made on examination.
