Acne can be frustrating enough on its own, but the aftermath—marks or scars—can leave lasting effects on your skin. Understanding the difference between acne marks and acne scars is crucial for choosing the right treatment. While both can result from breakouts, they differ in appearance, cause, and how they should be treated.
In this guide, we’ll help you identify whether you’re dealing with acne marks or acne scars and provide effective treatment options for each.
What Are Acne Marks?
Acne marks, also known as post-inflammatory hyperpigmentation (PIH), are dark or red spots left behind after a pimple heals. These marks are caused by inflammation that stimulates melanin production, leading to discoloration.
- Appearance: Flat, discolored areas that range from pink and red to brown or black, depending on your skin tone.
- Cause: Skin inflammation during a breakout triggers excess melanin production, leading to temporary discoloration.
- Behavior: Acne marks usually fade on their own over time, though it can take several months or even years.
Treatment Options for Acne Marks
- Exfoliation
- Use gentle chemical exfoliants like alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs) to remove dead skin cells and promote new cell turnover.
- Example: Products containing glycolic acid or salicylic acid.
- Brightening Agents
- Ingredients like vitamin C, niacinamide, and licorice root extract can help lighten discoloration and improve skin tone.
- Example: Serums with 10-20% vitamin C.
- Sunscreen
- Shield your skin from UV rays as they can exacerbate hyperpigmentation.
- Example: Broad-spectrum SPF 30 or higher applied daily.
- Professional Treatments
- Chemical Peels: Removes the top layers of skin to reveal a more even skin tone.
- Microneedling: Stimulates collagen production to fade discoloration.
- Laser Therapy: Targets pigmented areas to lighten marks faster.
What Are Acne Scars?
Acne scars occur when the skin’s natural healing process is disrupted, often due to severe inflammation or improper handling of acne (e.g., picking at pimples). These scars result in permanent changes to the skin’s texture.
- Appearance: Textural changes in the skin, including depressions (atrophic scars) or raised areas (hypertrophic scars).
- Types:
- Ice Pick Scars: Small, deep pits.
- Boxcar Scars: Broad, box-like depressions with defined edges.
- Rolling Scars: Wavy, uneven textures.
- Scars that are thick and raised, such as hypertrophic or keloid scars, form when the body produces too much collagen during the healing process.
- Cause: Severe inflammation damages skin tissue, leading to abnormal healing and scar formation.
- Behavior: Acne scars do not fade naturally and require targeted treatments for improvement.
Treatment Options for Acne Scars
- At-Home Skincare
- Retinoids: Encourage cell turnover and collagen production to reduce the appearance of scars.
- Example: Prescription-strength tretinoin or over-the-counter adapalene.
- Dermal Fillers
- Fillers like hyaluronic acid can temporarily lift depressed scars, creating a smoother appearance.
- Microneedling
- Creates tiny injuries in the skin to stimulate collagen production, improving texture over time.
- Laser Treatments
- Fractional CO2 Laser: Targets deeper scars to improve skin texture.
- Pulsed Dye Laser (PDL): Reduces redness and stimulates collagen in hypertrophic scars.
- Chemical Peels
- Stronger peels, such as TCA (trichloroacetic acid) peels, can improve textural scars.
- Sub Cision
- A dermatologist uses a needle to break up fibrous tissue beneath scars, allowing the skin to lift and smooth out.
- Surgical Procedures
- Punch Excision: Removes ice pick scars and replaces them with a small, smooth scar that heals better.
How to Tell the Difference
- Acne Marks: Flat and discolored, often fading with time and consistent topical treatments.
- Acne Scars: Textural changes that are permanent without targeted intervention.
Preventing Acne Marks and Scars
- Treat Acne Early
- Use proven acne treatments, such as benzoyl peroxide or salicylic acid, to reduce inflammation and prevent severe breakouts.
- Avoid Picking
- Picking at pimples increases the risk of scarring and pigmentation.
- Keep Skin Hydrated
- Well-moisturized skin heals better and is less likely to develop scars.
- Use Sun Protection
- Sunscreen prevents marks and scars from darkening due to UV exposure.
When to See a Dermatologist
If over-the-counter treatments don’t yield results or you’re dealing with severe acne scars, consult a dermatologist. They can recommend advanced procedures like lasers, fillers, or surgery to help improve your skin.
