Acne scars can be classified into "true scars" (atrophic or hypertrophic scars) and "false scars" (erythema or hyperpigmentation).
True scars, particularly atrophic scars, can be treated with dermabrasion; currently, most procedures utilize laser resurfacing, which causes less damage compared to traditional microdermabrasion and has a quicker recovery time.
Wound healing typically takes about one week, while redness may take one to two months to fade.
Some individuals may experience hyperpigmentation (dark spots), which can take approximately three to six months to resolve, depending on post-operative care.
The cost also varies based on the size of the treatment area.
Hypertrophic scars, which are related to individual skin types, can lead to raised keloid scars.
These can be managed with topical or injectable steroids or cryotherapy.
As for false scars, they usually refer to the redness or dark pigmentation left by acne, which typically fades gradually over time (about three to six months).
The use of whitening products and sun protection can help accelerate the fading process.

More Info
When it comes to effectively removing acne scars, particularly those caused by squeezing or picking at acne, there are several options available that are suitable for students. These methods range from topical treatments to professional procedures, and each has its own benefits and considerations.
Topical Treatments
1. Silicone Gel Sheets: These are often recommended for scar management. They work by hydrating the scar tissue and can help flatten and soften scars over time. They are easy to use and can be worn discreetly.
2. Over-the-Counter Creams: Look for creams containing ingredients like hydroquinone, kojic acid, or niacinamide, which can help lighten hyperpigmentation associated with acne scars. Retinoids (like adapalene) are also effective as they promote cell turnover and can improve skin texture.
3. Vitamin C Serums: Ascorbic acid (Vitamin C) is known for its brightening properties and can help reduce the appearance of dark spots left by acne. Regular application can lead to a more even skin tone.
4. Exfoliating Products: Chemical exfoliants containing alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs) can help remove dead skin cells and promote new skin growth, which can reduce the visibility of scars over time.
Professional Treatments
1. Chemical Peels: These treatments involve applying a chemical solution to the skin, which causes the top layer to peel off. This can help improve skin texture and reduce the appearance of scars. Many dermatologists offer student discounts or payment plans.
2. Microdermabrasion: This is a non-invasive procedure that exfoliates the skin and can help improve the appearance of scars. It’s generally safe for all skin types and requires little downtime.
3. Laser Therapy: While more expensive, laser treatments can be very effective for deeper scars. Fractional laser therapy, for example, targets the scarred areas while leaving surrounding tissue intact, promoting faster healing.
4. Microneedling: This involves using a device with fine needles to create micro-injuries in the skin, which stimulates collagen production. It can be effective for improving the texture of acne scars.
Home Remedies
While not scientifically proven, some people find success with home remedies such as:
- Aloe Vera: Known for its soothing properties, aloe vera can help with healing and may reduce scar visibility.
- Honey: Its natural antibacterial properties can help with healing, and it can also moisturize the skin.
Duration and Expectations
The time it takes to see results from these treatments can vary widely. Topical treatments may take several weeks to months to show noticeable improvement, while professional treatments can yield faster results, often within a few sessions. However, complete scar removal is not always possible, and some scars may only improve in appearance.
Conclusion
For students, it’s essential to consider budget-friendly options and consult with a dermatologist for personalized advice. Many treatments can be combined for better results, and starting with topical treatments is often a good first step. Always remember to use sunscreen daily, as UV exposure can darken scars and hinder healing. With patience and the right approach, significant improvements can be made in the appearance of acne scars.
