Acne Scars: What They Are and How to Treat Them
Do you have scars from your acne? I'm Dr. Heather, MD, a board-certified dermatologist, and let's talk about this! First, we need to clarify what "acne scars" actually means.
Key Takeaways
Two Types of "Scars": People often refer to dark spots left behind by acne as "scars," but these are actually post-inflammatory hyperpigmentation, not true scars. True acne scars involve changes in the skin's texture.
Types of True Acne Scars: Rolling scars, boxcar scars, and ice pick scars are the main types of textural acne scars. Ice pick scars are the most challenging to treat due to their depth.
Retinoids Can Help: Topical retinoids, both prescription and over-the-counter, can help improve the appearance of acne scars and rough skin texture.
See a Dermatologist: For optimal results, consult a dermatologist to explore the range of effective in-office treatments available.
Acne Scars vs. Dark Spots: Clearing Up the Confusion
So, there are two ways people talk about scars. Some people will point to dark spots from acne and call those acne scars. However, those aren't actually scars. They're just post-inflammatory hyperpigmentation or dark spots left over from acne. They're not permanent and usually fade over time, sometimes taking months.
These dark spots are completely different from true acne scars. When dermatologists say "acne scar," we're talking about actual changes in the texture of the skin.
Types of True Acne Scars: Rolling, Boxcar, and Ice Pick
The three main types of acne scars are:
Rolling scars: These create a wavy or uneven appearance in the skin.
Boxcar scars: These are wider, indented scars with sharp edges.
Ice pick scars: These are deep, narrow scars that look like tiny ice picks poked the skin. They're the most difficult to treat because they're very deep.
The Good News: Retinoids Can Help!
The great news is that retinoids can sometimes help with these types of acne scars. In fact, there was a study that looked at “tazarotene” (a prescription retinoid) and showed that it was equivalent to micro-needling in improving acne scars!
You can also try over-the-counter retinoids, which may be helpful with improving texture. Sometimes we see textural changes with acne where they're not true scars, but the skin texture is rough. With regular use of a retinoid, it can become smoother.
When to See a Dermatologist
If you have acne scars, I definitely recommend you see a dermatologist. We have some really effective treatments available, including:
Micro-needling: Creates tiny punctures in the skin to stimulate collagen production.
Laser therapy: Uses different types of lasers to resurface the skin and reduce the appearance of scars.
Chemical peels: Use acids to remove the top layer of damaged skin.
Fillers: Can be used to fill in depressed scars.
Over-the-Counter Options: Retinoids and Salicylic Acid
If you want to try something over-the-counter, I would definitely start with a retinoid like adapalene (Differin Gel), using it at night. You might even add in a salicylic acid wash, as both of these will help to exfoliate, increase cell turnover rate, and make the skin look smoother.
Conclusion
Acne scars can be frustrating, but there are effective solutions available. Whether you opt for over-the-counter retinoids or seek professional treatment from a dermatologist, remember that consistency is key!
