Some acne scars will diminish over time, and eventually disappear altogether. But some scarring is permanent, and won't go away on its own. If that's the case for you, it might take more drastic measures to deal with your problem.

These are five common techniques used to treat scarring, from mild to severe. Maybe one will be right for you.

Soft Tissue Fillers

How do you feel about needles? Well, with this technique, and injections are made under the skin, and scars are filled with either collagen, or excess fat that's been retrieved from another part of your body. The result is less noticeable acne scars for about 6 to 12 weeks. Then, you might choose to have the treatment again.

Collagen injections can cost between $300 and $400 for each treatment. Fat injections cost about $1000.

Microdermabrasion

A microdermabrasion treatment removes surface skin cells. Think of it as buffing the skin. The results of these treatments can be less visible acne scars.

You might need several treatments to get the result you want. But microdermabrasion treatments are fast, usually taking less than an hour. And there is little, if any, pain involved.

You can expect to pay $200 to $300 per microdermabrasion treatment.

Dermabrasion

During a dermabrasion treatment, a rotating wire brush is used to remove the top layer of the skin, along with surface acne scars. Deeper acne scars will also be less noticeable.

If you have mild or moderate scarring, you should probably try other, less drastic treatments first. But, if your scarring is severe, dermabrasion might be right for you.

You should expect to pay between $1,000 and 1,500 for dermabrasion.

Laser Resurfacing

During laser resurfacing, a laser will be used to destroy your skin's out layer. At the same time, the layer of skin underneath will be heated. When that layer of skin starts to heal, new skin will begin to form. And you will be left with fewer, and less visible, acne scars.

Laser resurfacing can cost between $2,000 and $2,500.

Chemical Peels

Chemical peels can sometimes make mild acne scarring less noticeable.

A chemical peel, a product that contains acid, is applied to your face, and then removed after a certain period of time. When the chemical peel is removed, the dead upper layers of your skin are removed with it.

A chemical peel can cost between $100 and $300, and it might take 3 to 6 treatments before you see real results.

Are you concerned about healing acne scars? Well, there are plenty of options available to you, whatever your budget.
