To prevent scars, protect a fresh wound from infection, avoid picking or squeezing the area, keep the site lightly moist and covered while it heals, and shield healing skin from sun exposure. If a wound is deep, shows signs of infection, or you have a history of keloids, see a dermatologist for early evaluation and care.
Why scars form and what makes them different
Scars form when the body repairs skin after injury. Collagen is laid down in a different pattern than the original skin, and that difference is what you see as a scar. Some scars are flat and pale, some are depressed, and some grow above the skin as hypertrophic scars or keloids.
Skin type, the depth of the injury, the location on the body, and how the wound is cared for all affect how a scar looks. For a short overview of dermatology as a specialty that treats scars, see the dermatologist entry on Wikipedia for background information: https://en.wikipedia.org/wiki/Dermatology. For practical prevention and early care guidance, the American Academy of Dermatology maintains current patient resources on scars and wound care: https://www.aad.org/public/diseases/cosmeceuticals-scars.
Common mistakes that make scarring worse
- Picking, squeezing, or peeling scabs, which disrupts healing tissue and raises the chance of a larger scar.
- Waiting to treat infected or deep wounds, which increases inflammation and scar tissue formation.
- Not protecting healing skin from sun exposure, which causes darker, more obvious scars.
- Using harsh cleansers or abrasive scrubs on healing skin, which can irritate and delay repair.
- Attempting at home lesion removal or aggressive DIY procedures, which can leave irregular scars.
- Skipping follow up after an in office procedure, which can prevent timely intervention if healing is abnormal.
How we recommend caring for a new wound
- Clean gently. Rinse the area with clean water and mild soap, then pat dry.
- Keep the wound moist and protected. Apply a thin layer of a bland ointment and cover with a nonstick dressing while it is open and draining.
- Change dressings appropriately. Replace coverings when they are dirty or wet to reduce infection risk.
- Avoid picking scabs. Let the skin heal under the scab or dressing to reduce scarring.
- Use sun protection once the skin has closed. After the wound has sealed, use broad spectrum sun protection or physical cover to prevent pigmentation changes.
Watch out: Increasing pain, spreading redness, draining pus, fever, or rapidly growing lumps under the skin can be signs of infection or abnormal scar development. These findings warrant prompt medical evaluation rather than more home care.
When early dermatology care helps
Early assessment by a dermatologist can reduce long term scarring for deep wounds, infected injuries, surgical sites, and areas prone to keloids. We evaluate wound depth, your medical history, and risk factors and recommend treatments that may include topical therapies, silicone applications, steroid injections for raised scars, or procedural options tailored to the scar type.

Preventing acne scars and treating acne early
The best way to avoid acne scars is effective control of active acne. That means a plan that reduces inflammation and prevents new lesions from forming. For readers who want an overview of treatment choices for acne and how they affect scarring, our Acne Treatment service page outlines options: Acne Treatment.
We also recommend that people with recurrent or severe acne see a dermatologist early, because timely medical management lowers the risk of permanent marks.
Pro tip: Silicone gel sheets or silicone gel applied after the wound has closed can reduce the height and redness of many raised scars. Discuss timing and product selection with your dermatologist.
Procedures, timelines, and realistic expectations
Scar improvement is often gradual and may require multiple approaches. Laser therapy, steroid injections, microneedling, and minor excisions are common options for different scar types. Timing matters. Some treatments are best started after the scar has matured, while others are more effective when applied early. We balance medical and cosmetic goals when recommending the right sequence.

Practical checklist for reducing long term scarring
Quick scar prevention checklist
- Clean wounds with mild soap and water.
- Keep wounds lightly moist and covered while they drain or are open.
- Avoid picking or manipulating healing skin.
- Follow post procedure instructions from your clinician.
- Protect healed skin from sun exposure with clothing and sunscreen.
- Ask about silicone therapy for raised scars after closure.
Key takeaway
Most avoidable scars result from mechanical disruption, infection, sun exposure, or delayed care. Careful wound management and early evaluation by a dermatologist reduce the chance of a permanent, visible scar.
Frequently asked questions
Will every cut or pimple leave a scar?
No. Many minor cuts and pimples heal without lasting marks. Scarring is more likely with deeper injuries, prolonged inflammation, infection, or repeated trauma to the area.
When should I seek dermatology care for a wound?
Seek evaluation for deep wounds, wounds with spreading redness or pus, wounds that do not show steady improvement in a few days, surgical wounds that look abnormal, or anytime you have a history of keloids.
Are silicone sheets backed by evidence?
Yes. Silicone sheets and topical silicone gels have clinical support for improving the appearance of many raised scars when used as directed after the wound has closed.
Can sun exposure make scars worse?
Yes. Sun exposure during healing can darken scars and make them more noticeable. Use sun protection over healed skin and follow guidance from your clinician on timing.
Do you treat keloids and hypertrophic scars?
We offer evaluation and treatments for raised scars, including medical and procedural options. For information on management choices and realistic outcomes, see our Scar Removal and Cosmetic Dermatology pages.
