Great product for an easy skincare boost.
[This review was collected as part of a promotion.] Surprised me in the best way! It’s lightweight, absorbs fast, and has noticeably improved the texture and tone of my skin. After a few weeks my skin looks smoother and more radiant.

I would definitely recommend this!
[This review was collected as part of a promotion.] I definitely saw slight improvements in the appearance of my scar within the few weeks I used this! I honestly love how fast it absorbs and how it doesn't leave any slimy or greasy residue.

Didn't work
[This review was collected as part of a promotion.] I personally didn't notice any difference after trying this for several weeks. I don't know if this only works on certain types of scars. It goes on smoothly and no residue. No scent.

Good but not a dramatic change
[This review was collected as part of a promotion.] Ive been using merderma scar serum triple action formula for a few weeks, and it’s okay. The serum itself feels mice going on, absorbs quickly, and doesn’t have a greasy residue. I do like that it includes niacinamide, hyaluronic acid, and vitamin E, which made my skin feel more hydrated and smoother over all. I did notice my skin texture was smoother but not much in appearance.

Meh for me
[This review was collected as part of a promotion.] I personally did not see a huge difference in using this. I have fairly regular skin that is kept up well with lotion, sunscreen, moisturizing, etc.

No change
[This review was collected as part of a promotion.] I used this on my C-section scar and a scar on my face. I don’t know if it was just that I hadn’t used it enough but I didn’t see a noticeable change which was a bummer.

Use it regularly for optimal results
[This review was collected as part of a promotion.] I bought Mederma 3-in-1 Serum for Old Scars to help with dark spots from old blemishes, and I feel like it worked. With consistent use, the spots cleared up, and my skin looked more even overall. It absorbed well, didn’t feel greasy, and I didn’t have issues with irritation. It’s not an overnight fix, but it made a real difference for me with steady use.

[This review was collected as part of a promotion.] I tried it on a spot on my chest that I thought was a scar, pretty sure it’s actually a cyst. So I cant really give much of a review. I am going to try it on other scars, actual scars and ill come back to update!

Mild formula for people with sensitive skin reduci
[This review was collected as part of a promotion.] Being a woman with sensitive skin, I was reluctant to test and review this product. I have a scar on my forehead from a car accident over twenty years ago. So I have used this product specifically on this area. It provides great coverage to the applied area as well as I have not had any skin irritation to my forehead.

Serum for scars
[This review was collected as part of a promotion.] I’ve been applying the serum for a couple weeks and haven’t seen much improvement in the scars. It’s a good moisturizer and makes my scars less itchy, but no big changes in the appearance yet. I’ll keep applying to see if better results come up

Felt like I saw a change for the period of time us
[This review was collected as part of a promotion.] Tried to show some before/after for visuals. Was mainly targeting some old acne scars on my cheeks along with an old scar I have by my nose from a dog bite. Product applied really nice and sunk into the skin so it was really easily to wear and didn't cause any irritation. Pump top was easy for guiding how much product I needed. Overall, I didn't notice a crazy change but did feel like my cheek acne scars got a lil smoother and that my scar on the thinner pieces seemed to be a lil less noticeable but I didn't notice a huge change in the bulkiest and deepest part (photos are included so you can access too). For the time I tested it though I felt these were decent results and even besides that my skin seemed to like the formula so I'm going to continue testing and see how it goes!

Mederma 3-in-1 Serum for Old Scars is a must have
[This review was collected as part of a promotion.] I was recently sent a tube of Mederma 3-in-1 Serum for Old Scars. I decided to use it on an old burn I got during Christmas while getting food out of the oven. I read the instructions & dispensed a pea sized amount on the affected area. Overall, my wrist burn definitely feels better & the formula isn't greasy or sticky. I will try it on my other scars as well. I highly recommend it.

Gentle
[This review was collected as part of a promotion.] I have several old scars that this is perfect for. You need to use it consistently for effects to be shown. It’s very gently and creamy with no odor and no residue. It absorbs fast and a small amount goes a long way. I will keep using!!!

Small improvements, but give it time.
[This review was collected as part of a promotion.] I used this product for 2 weeks on a scar that I have had for approximately 10 years. I did not see a tremendous amount of improvement, however the edges seem to contrast with my skin less than they did before using this product and the tone of the scar seems more consistent overall. The product took approximately 10-15 minutes to dry on my skin which made it difficult to not smear or remove from the area it was needed in.

So far so good
[This review was collected as part of a promotion.] Great for as long as I have been using it for. I usually like to fully use the product before reviewing. Scar has gotten lighter which is better than what I had.

Great for reducing the look of scars!
[This review was collected as part of a promotion.] As someone who has many many old scars on my arms and my face from frequent picking in my childhood, I was really excited to try this. It worked really well on my arms and I want to try it on other scars. Easy to use, didn’t smell, no irritation, no issues.

Unsure
[This review was collected as part of a promotion.] I'm honestly not sure if this works well on prominent, big scars. Maybe with a little more time, it could help fade my scar a little more, but as of now I do not really see much of a difference.

Works well
[This review was collected as part of a promotion.] I liked this gel and will continue to use it! I do think I saw slight results in the appearance of older scars, helping to reduce redness and tightness of the scar. I’m excited to see longer term results

Works as Intended
[This review was collected as part of a promotion.] This scar serum did its job. I used it every day over the course of two weeks and slowly seen a difference with this older light scar on my knuckle. I like the packaging and pump container. The serum has a lightweight milky consistency and easy to apply. It absorbs into the skin leaving the area hydrated. It has little to no scent which is great. I think it’s worth the price, you just have to be consistent and apply it as recommended.
