Reasons to Add Vitamin C Serum to Your Regimen

As we age, our skin naturally tends to show more signs of photoaging, such as fine lines and wrinkles. One of the ways our skin can help keep itself renewed and healthy-looking is with antioxidants like Vitamin C.

  • Enhances UV protection,
  • Calms Skin,
  • Helps keep skin hydrated by enhancing moisture content. Add Vitamin C serum every day and watch it work hand-in-hand with a daily moisturiser to help skin stay fresh-looking and moisturised,
  • Topical Vitamin C helps brighten the complexion for a more youthful, fresh looking skin, which is the marker of vibrant health.

    Arrived in excellent condition and packaging was enough to keep the glass bottle from moving around in the box. IÕve used this serum a few times and every time, it tingles my entire face for at least 5 mins. Instructions do say to be aware but it may be too intense for me. Overall, the serum glides on easily and doesnÕt leave a residue. Hoping that the tingling goes away soon.

    I have been using this for almost a month. I had hyperpigmentation around be hairline on both sides of my face. My face was dull and tired. Once I stated using this, I noticed my face looking brighter. The dark splotches around my hairline were fading. My skin is looking so much better. I can pull my hair back without hesitation. My skin is glowing. This stuff is amazing.

    I bought this after a friend suggested it and how I noticed how her face has really looked younger. I have been using it for 3 weeks and have already seen a difference. My husband even thought I got work done on my face. I love it and will continue to use this and very affordable.

    IÕve been using this for about three weeks now and I like the results! Healthier looking skin. Brighter, smoother, clearer skin. I apply it in the morning to clean skin and follow with moisturizer. Like the little tingle and the antioxidants!

    I have been using Obaji products for about 13 years. I tried using the over the counter brands ,but nothing makes my face feel, and look as soft n smooth like this product, started using professional C serum instead of # 4 about 6 years ago, and the darks spots are starting to lighten up ,giving me a even skin tone with in a few wks after use.

    After my dermatologist recommended that I use a vitamin C serum on a patch of damaged skin, as well as my face and neck. Knowing that if I didnÕt see quick results I probably wouldnÕt continue to use it, I decided to go with the 20% serum. I also incorporated a toner into my daily routine. Within 3 weeks, I saw healthier, brighter skin on my face and the lines on my neck faded a little. On the patch of damaged skin, I am seeing an improvement, although not as drastic. I used to get unsolicited comments on the extreme redness and I have not received those in a while. IÕve experienced tingling that a few other reviewers had mentioned, although not uncomfortable and not all over. Overall, I am very happy with my purchase.

    I am 71 years old and people always say that I look like I am in my forties. I give most of the credit to my Obagi 20% Vitamin C Serum. I love it. I really stopped using any skin-care products during the Covid time-frame and it showed. When I started using the 20% again-my husband noticed the difference immediately. He thinks that my face looks brighter and more vibrant. YAY.

    I began using the Obagi Professional C serum recently and really like it. It comes in a dark bottle to preserve the serum and includes a dropper to measure how much to use. I use 5 to 7 drops every morning on my face, before using moisturiser, as per directions.It makes my face feel smooth and gives it a dewey finish.I love having a nice glow on my face!

    I have seen the texture of my skin with the daily use of this vitamin C . I wish I could give this blue bottle more than 5 stars.,

    I purchased this for myself about 3 months ago and I absolutely loved it!! So I decided to get my mother one, she is 62 and has really good skin, but thought since she lives in Arizona her skin can get al IÕll dry and dull. She has been using for the past 3 weeks and her skin is visibly more radiant and brighter, she has been getting so many compliments on her skin lately and itÕs thanks to this serum.

    I’m happy you can now order products directly for Obaji, because it can be a hassle sometimes trying to find a clinic that have exactly what you need.

    This vitamin C serum is awesome! This Serum has a slightly oily feel when applied, but totally absorbs within a few minutes. It doesnÕt make my skin break out and I have noticed it has made my skin brighter and more even toned. The texture and smell are great and makeup goes on smooth on top. I will continue buying. CanÕt wait to continue to see results!

    I love this serum. I can tell a big difference when using it. My skin is more clear and it helps lighten the dark spots.

    LOVE this! It works very well and feels so good on my skin. I’ve used it for several years and it shows. It’s pricey but you only need a few drops every evening. When I tell people how old I am they never believe me. I like that!

    Moisturizes your skin! I donÕt even need a cream or moisturizer gel when I use this serum. Not only does it help make my face look and feel better with a youthful glow, I am also nourishing and protecting my skin. Have tried other vitamin c serums from the dermatologist office and Obagi is the very best.

    This product produces RESULTS. This is my secret weapon, and is in a league of its own. I havenÕt found any other product – none – that matches this serum. My skin is brighter, tighter, and I GLOW.

    I have used the Obagi Professional Serum for about week. I like the way it makes my skin look and feel. It is easy to use and I also like how it is intended for face, neck and chest. The only improvement that could be made is fragrance.
