Which is better for moderate acne scars and sun damage? Is one better for one or the other? Should they be combined?
Chemical Peel vs Microdermabrasion

Microdermabrasion does not remove scars
Microdermabrasion will not remove scars but can improve brown spots left over from acne lesions. It will also improve discolorations and coarse texture caused by sun damage. Light chemical peels will have the same effect. Stronger light and medium peels, such as TCA peels may improve scars and wrinkles but not as effectively as some lasers. Deep peels will remove scars but can also cause permanent loss of skin color and are therefore have been replaced by more better technology (lasers.)
Better results with chemical peels
I have seen improvement in the appearance of ance scars and sun damage with chemical peels and microdermabrasion. In my opinion, results can be seen sooner with chemical peels since exfoliation can be cutomized to meet the needs of your skin and can be stronger than microdermabrasion alone. Microdermabrasion is more superficial and is a great option to maintain your skin after you achieved your desired result.
Depending on your skin type chemical peels can be combined with microdermabrasion for deeper exfoliation. Most skin conditions, including acne scars and sun damage, require a series of treatments in the range of 6-8 depending on how strong the treatments are. I recommend a consultation with a skincare professional who can recommend the best treatment course for your specific condition. Good luck!
Improving acne scars and sun damage
The discolorations left behind from acne lesions are not truly scars but rather post-inflammatory red or brown color. True acne scars leave behind tissue loss and indentations in the skin. Post-inflammatory color can be improved both by microdermabration and chemical peels. Each technique can provide superficial resurfacing of the skin. Your skin cells turn over every 28 days.
Alternating microdermabrasion with chemical peels on a monthly basis will take advantage of the cells normal cycle and achieve excellent results with minimal risk of irritation. There are many different types of peeling agents which can achieve different depths of chemical peel each tailored to the individual patient and their goals. As with any treatment plan consult a skin specialist, especially a board certified dermatologist, to design the right program for you.

Fraxel For Acne Scars
Moderate acne scars and sun damage can be treated many ways.
Microdermabrasion will remove the top, dry, rough skin layers and will leave your skin softer and smoother. This procedure is similar to how your skin would feel after a nice facial. Microdermabrasion will have very little to no effect at all on acne scars (even mild ones), as these scars are within and often extend below the deeper skin layers. Even the deepest laser resurfacing, surgical dermabrasion, or strongest chemical peel will not completely remove or eliminate moderate or severe acne scars.
However, all of these options will have some beneficial effect on your skin, removing much of the sun-damaged irritations or rough patches (actinic keratoses), and improving, but not eliminating the acne scars.
As a general rule, you get what you pay for. Lighter chemical peels treat the most superficial layers, make minimal changes in true irregular scars or textural changes in skin, and heal quickly. That is why they are often done in a spa or skin care clinic by estheticians, and don't cost too much.
Stronger peels (higher concentration TCA or phenol peels) go deeper into the skin layers, remove more textural changes and scarring, but will still not be as aggressive as full-face ablative laser resurfacing, which gives the most improvement and best results, but costs more. No matter what procedure you have, the healing still takes about a week, and there may be redness that lasts somewhat longer.
Chemical peels are best
The biggest bang for your buck, so to speak, is definitely chemical peels. There are a variety of them to chose from and if done properly can make a big difference even for deeper acne scars. Microdermabrasion, in my opinion, will make little, if any, difference.
Chemical Peels tend to do a lot better for discolorations and sun damage than microdermabrasions.
There are many types and strenghts of chem peels which work great for discolorations and sun damage but still usually need to be done 4-6 times. Microdermabrasions do well to maintain your complexion once the peels get it to where you like it.
