On a medium sized (1/3 inch) circular raised scar (deep in the skin), it did almost nothing for this scar after at least 6 months of use. I DID notice, however, that the non-scarred skin around the scar became noticeably lighter compared to the skin where the ointment did not cover. I also tried it on a small indented acne scar on my face that began as a scar, and this one disappeared completely. I think for smallish certain types of scars (where there isn't a significant amount of actual scar tissue), this works. Both of the scars were new.

I think the effectiveness of skin products really depend on your skin type. (I have Irish fair skin with a tendency toward dryness.) I've tried other 5 star (and far more expensive) stuff for scars and stretch marks, and it didn't work at all. This product has significantly lightened a deep surgery scar on my hip, and has (surprise!) worked wonders on 7+ year old pregnancy stretch marks too!

I was in a very bad car accident which left an ugly big scar on my face. I had heard about Mederma and other products for scars. I was so depressed, thinking that nothing was going to work on my scar. I bought this lotion and started applying it every day for a whole week - maybe twice a day. This product works miracles! My scar is almost not noticeable. I'm so happy that Mederma really did work for me. I thank this product; when I came home from the hospital and I saw my face, I honestly felt suicidal. I looked so ugly, and now it's almost gone and I feel happy with no insecurities. Thank you...awesome product!

If you have realistic expectations, Mederma is a miracle! I had gotten a third degree burn from an exhaust pipe and it left a big, raised, purple scar on my leg. I didn't start to use Mederma until about a year later, and after only 3 days I could see a small difference in color. I just finished the tube last week and now the scar is barely visible. Also my dad who has an open heart surgery scar from two different surgeries uses it, and says although his scar is still raised it helped a lot with the color.

Amazing so far. I've been using Mederma for 3 days and already see major improvement on a rather new (but pretty dark) acne scar. No irritation or stinging. Well worth trying.

I would highly recommend this product to those suffering from surgery scars. I had a tattoo removed from my lower ankle two months ago and it became infected and left a red/brown slightly raised scar. After the wound finally healed, I purchased Mederma last week and started using it on the scar 3-4 times a day. Within the first day of use, I noticed the redness of the scar became less apparent and the scar also felt somewhat flatter. One week later, the scar continues to improve in feeling and appearance. I have noticed that this product has received many negative reviews, but believe that the customers who purchased this product may not have applied the gel as diligently or as frequently as they should have in order to obtain the best results. Keep in mind older scars will take many months of therapy, and you will see quicker results with newer scars.

Despite some of the negative reviews this product has received on drugstore.com, I purchased this product to help reduce the appearance of a very raised, dark reddish/brown scar on the underside of my forearm. The scar resulted from a nasty cut that I received about 7 months ago. After using this product for only one day (!), I noticed a difference in the scar. It was slightly lighter in color and not quite so raised. I have been using it for the recommended 3-4 times a day for about two weeks now, and I notice the scar fading more and more each day. It is somewhat annoying to have to apply this product so often each day and the smell is not great (not horrific, just mildly obnoxious), but if it works, I am willing to put up with all of the negatives. I would recommend this product. It has worked for me so far.

This product is good for marks and scars on the skin. It did nothing for my stretch marks, but cleared away scars on my skin. The trouble is you have to use it on marks as soon as the wound seals up. For older scars, it takes patience and about 6 months to start working. It fades away surgical scars a little but will work better if used soon after surgery. SO, always keep a bottle at home so that you can apply it as soon as your scar seals up!

This stuff is worthless! I cannot believe the price of this, and yet I bought it for some reason. I used it for 3 months straight twice a day like it says on the box and it did absolutely nothing.

This product maybe only works on people who have surgery. I bought this item because one of my friends told me that it works on her acne skin very well. I tried it on my acne scars and also some others like stitches on my face near lips. This item did NOTHING, except put a burning feeling on my face and guess what, when I woke up in the morning, there were many little red patches on my face!!! I won't use product anymore.
