  1. DFS is a Fav

    by DOEPOWELL on

    I am only been using for 2 months and have definitely seen results. My skin is much firmer and it only takes a few drops.

  2. DFS is my BFF

    by Rosemary McClane on

    Been using DFS for decades. No other Vitamin C Serum comes close to the effect — makes skin look moist and dewy, minimizes wrinkles. Hate to think what I would look like without it!

  3. Vitamin C to the Rescue

    by Ginny Hounsell on

    Deep Firming Serum is my top pick….my skin loves vitamin C and the serum invigorates and brightens it. I love the little zing I feel when I apply it; immediately makes my skin appear more youthful, not kidding!

  4. Chamonix Deep Firming Serum

    by Kandi on

    I’m going on 44 and have been using this serum for two years. It truly is the very best for age defying results. Just last week I received a compliment that a receptionist gave me. She thought I was 28. I told her about this serum and she immediately ordered.

    I cannot recommend this enough! I call it my fountain of youth in a bottle.

  33. by Cheri on

    I give this product 5⭑ Vitamin C is one of the most powerful antioxidants in skin care. It not only slows down the aging process it has shown to improve the appearance of wrinkles. I only started using Chamonix D.F.S for a month, and my skin looks radiant, supple and youthful. Great product!

  34. by Lanna on

  38. by Jill W. on

    I love this oil. I’ve tried several high end oils on the market and none work as well as this. My skin is visibly tighter and appears smoother with this product. By far the best out there.

  39. by Lori on

  40. by Kerri on

    I love this product. My skin is so soft and I am getting a lot of comments on the clarity of my skin.

  41. by Mary on

    I have always been a “fan” of Clinique products until I tried the products by Chamonix. I am very picky when it comes to serums and moisturizers, until I tried this deep firming serum. On day 1 I felt the difference on my skin immediately, it was not greasy nor sticky (as many other serums are), I felt a slight tingling, which made me realize this product really works. I have been using this product for about 2 months and highly recommend it.

  42. by Bernadette BenShay on

    I have used the deep serum for as long as I have been using Chamonix which is approximately 6 months. Using the deep serum with my Chamonix moisturizer and eye creme. The deep serum is the base of good skin care. I have had comments on the appearance of my skin, I attribute this to the deep serum as well as my entire line of Chamonix.

  48. by Bernadette BenShay on

  62. by Ellen from New Harbor on

    This serum is probably the best one of its kind that I have tried over the years. I noticed a difference in the appearance of my skin tone and condition after just a few days of use. I apply it twice a day and follow up with Esotique-RF with Matrixyl moisturizer. I love the results and would highly recommend these products to anyone.

  69. by Rachel from Dunn on

    Someone recommended this product to me over 2 years ago and I’ve been using it twice daily ever since. It smoothes and tightens the appearance of my skin like nothing I’ve tried before.

    A great serum to use before applying Esotique-RF. I love both products and have been using for a couple of years now with great results.

  79. by Diane Higgins from Stroudsburg, PA on

    I would never use any other product. After using it for a year the results are still fantastic. I also use Esotique-RF and L’essence Neck Treatment.

  80. by Anita Samet from West Orange, NJ on

    This product is incredible. It actually erases the appearance of lines in a matter of days. I find using it morning & evening to be the most effective.

  81. by Sarah Kisner from Wall Township, NJ on

    People love my “dewy” appearance.

  82. by Elvira Tsirulnik from Staten Island, NY on

    My friend recommended me the product a long time ago but I did not believe in a quick results. Fortunately she just gave me the serum. after I start using it I changed my mind. I sow the difference in a few weeks. I think I will never stop using Chamonix products.

  83. by Dolores Headlee from Gainesville, VA on

    Great Product. Really value for money.

  84. by Karen Peterson-Saunders from Harleysville, PA on

    I use this product twice a day and it has really made a difference. This is the best product I have used that contains Vitamin C. I use it in conjunction with Esotique-Rf, Jeunesse eye treatment and serum.

  85. by Lauren Kieffer from Navarre, FL on

    I just love this product! Just after a few days, my skin appears much softer and has a healthy glow. The difference is so dramatic that I will continue to use this serum on a daily basis!!!

  86. by Linda Ratti from Massapequa, NY on

    This product is not like any other serum I have used. It makes your skin glow and allows cream blush to glide on your skin….I have tried many other serums and have come back to this time and again….

  87. by Diane Mallos from Irvine, CA on

    I love this product. I notice a difference in my skin and so has my family. If I get lazy and forget to use it for awhile, can see the change in my skin…for the worse. That is why I try never to skip an application on a daily basis.
