Scars are a normal part of healing — but how a scar matures over the months after surgery or birth can vary enormously. Some scars settle flat and pale with very little intervention. Others become raised, thickened, itchy or uncomfortable, and can restrict movement or sensation in the surrounding tissue.

The good news is that the early weeks and months after a wound closes are a window of opportunity. The right products, used consistently and at the right time, can make a meaningful difference to how your scar looks, feels and moves — and they work best when combined with hands-on scar massage and physiotherapy.

This guide covers the main categories of scar product, what the evidence says, and when to start using them.

The most important rule: the wound must be fully closed before you apply anything to it. This means no open areas, no scabbing, and no signs of infection.

For most people, this means:

• C-section scars: around 6–8 weeks after surgery, once your midwife or GP has confirmed the wound has healed
• Perineal tears or episiotomy scars: typically 6–8 weeks, once the stitches have dissolved and the area has healed
• Other surgical scars: follow your surgeon's guidance, but 6–8 weeks is a common starting point

Starting too early — before the wound is fully closed — risks introducing infection and can delay healing. If you're unsure, ask your GP or midwife to check before you begin.

Silicone is the most well-evidenced topical treatment for scars. It works by hydrating the outer layer of the scar, which helps regulate the production of collagen — the protein responsible for scar tissue. This can reduce redness, flatten raised scars, and improve overall texture over time.

Silicone comes in two main forms:

Soft, flexible sheets that you wear directly over the scar. They need to be worn for several hours a day — ideally 12 hours or more — for best results, and most are reusable for several weeks.

Good options to look for:

• Kelo-cote Silicone Sheet
• Cica-Care (available on prescription in some areas)
• ScarAway Silicone Sheets

Silicone sheets work well for C-section scars and other flat, accessible scars. They're less practical for perineal scars.

A clear gel you apply directly to the scar and allow to dry. It forms a thin silicone layer over the scar and is more practical for areas where a sheet won't stay in place.

Good options:

• Kelo-cote Gel
• Dermatix Ultra
• BAP Scar Care Gel

Apply twice daily to clean, dry skin. Allow to dry fully before dressing.

Oils and creams don't have the same level of clinical evidence as silicone, but many people find them helpful — particularly for keeping the scar supple, reducing itching, and supporting the massage work.

One of the most popular choices for scar care. Rosehip oil is rich in essential fatty acids and vitamin A, and some small studies suggest it may help improve scar colour and texture. It absorbs well, is gentle on sensitive skin, and is widely available.

Apply a few drops to the scar and massage gently in circular motions once or twice daily. Bio-Oil contains rosehip oil alongside other ingredients and is another commonly used option.

Often recommended for scars, but the evidence is actually mixed — some studies show benefit, others show no effect, and a small number of people develop a contact reaction. If you want to try it, patch test first and discontinue if you notice any redness or irritation.

A popular natural option. It's moisturising and generally well tolerated, though the evidence for scar improvement specifically is limited. It can be a good carrier oil for massage if you prefer something natural and fragrance-free.

Products like Contractubex (containing onion extract, heparin and allantoin) have some evidence behind them, particularly for raised or hypertrophic scars. They're available from pharmacies without prescription.

• Fragranced products on a fresh scar — these can cause irritation or sensitisation
• Anything with alcohol as a main ingredient — drying and potentially irritating
• Essential oils undiluted — always dilute in a carrier oil, and avoid on new scars
• Exfoliating products — too harsh for scar tissue in the early stages

Topical products work best as a complement to hands-on scar massage — not a replacement for it. Massage helps to mobilise the scar tissue, break down adhesions, and restore sensation and movement in the surrounding area. It's something I teach all my clients as part of scar therapy, so you can continue the work at home between sessions.

If your scar feels numb, tight, raised, or uncomfortable — or if it's affecting your movement, posture or confidence — it's worth getting a proper assessment. Scar therapy can make a real difference, even for scars that are months or years old.

I offer scar therapy as part of my women's health physiotherapy practice in the Surrey Hills and at Key Osteopaths in Walton-on-Thames. Get in touch if you'd like to find out more.
