Deep wrinkle serum that works if you're diligent using it on a daily basis. I use it day and night and slowly I see the difference.

The best serum that I have ever tried. Great bang for your buck.

I definitely like this product. Seems to Help to smooth out my skin at least making the appearance of the wrinkles I have look more reduced! Thank you!

I cannot say enough about TruSkin HA as well as TruSkin C. Together they have helped prescription Tretnoin cream (and erythromycin or clindamycin lotion for chest and back) and cleared my adult acne. The C has also brightened my complexion and lessened discoloration without aggravating my unusually sensitive skin (Graves' disease) The HA is a gift that plumps my mature skin and reduces the large pores that show up on the cheek and nose area. I use HA twice a day and C every other night.

To alternate with TruSkin C, I have a separate Vit B3, niacinamide solution that I make in small batches from Bulk Supplements that I bought on Amazon. For this I mix a tiny bit of B3 powder in water and shake in a few beads of light oil to create a micellar-like water mist, used on the 3 days I do not use my TrueSkin C. I use HA every day, but B3 and C should not be used at the same time, as I learned from my experience with a fancy "superfood" moisturizer, shared below as an example of one way TruSkin's less is more approach to skin care formulation is of help to sensitive and problem skin.

Following an extensive comparative search of brands offering HA on Amazon and Nordstrom, my mainstays, I chose TruSkin HA and C serums. Where I went wrong was in my decision to purchase a fancy cream on Nordstrom ($72) thinking that with time it could potentially replace several products, because the fancy cream touted itself as an adaptive superfood and skin repairing moisturizer cream for any skin type. At about 35 ingredients, fancy cream was loaded with HA and all manner of apparent goodness including; catastrophically as I now know; a high level of B3. Niacinamide- a no no in the presence of acids, albeit likely used in small amounts: A trademarked superfood, the fancy cream formulation boasted of many beneficial fruits, most known to naturally contain Minerals and Vitamins, especially Vit C, such as plums, Kiwi, and Goji Berries. A few fatty acids were listed towards the end. I reckoned the high cost of one fancy cream with all desired ingredients would prove justified with time. But, as I was later to learn, some of the properties that I was after in the fancy cream should have been addressed separately and ingredients appropriately formulated away from each other. In this case, I concluded that Niacinamide, broken down in the presence of acids in the fancy cream, caused me to experience "˜the flush.' Some people love the flush, believing the warming sensation and skin flush to be evidence of B3 at work. But for me as for others with sensitive skin, what I got from the fancy cream superfood environment was not a momentary sensation, but rather a persistently red irritated face that bothered me no end until I stopped exposing myself to it. Although rich in HA, the B3-Acid combo renders the fancy cream toxic to some, in contrast to its intended application as a calming product for troubled skin.

In this, TruSkin has succeeded, leveraging 4 simple products in the form of 3 different serums and a moisturizer; where the fancy cream had heavy handedly combined otherwise beneficial ingredients so that the user couldn't avoid unknown interactions. Happily, once established in my TruSkin regimen, my skin stayed dewy and it turned out that I no longer needed a heavy moisturizer like the fancy cream and others I had used in the past on a twice-daily basis.

On TruSkin HA, I forego a moisturizer for Supergoop Play or Supergoop Unseen Sunscreen; which I love for its matte smoothing effect. I forgo foundation for a little Bobbi brown bronzing powder on my temples, cheekbones, and décolleté.

On TruSkin, I am using less skin care products, and feeling the need for little to no makeup these days. As a result, I am definitely washing my face less, which means I get to protect my natural moisture barriers, promoting even better skin.

After several months, I am only now seeing the bottom of my second bottles of HA and C serums, looking to buy the third bottles soon. One only needs a couple of drops, ergo I have found TruSkin serums to be long lasting and economical.

Lastly, I should mention that When did have reason to email the company seeking clarity on HA versus C bottling, I was afforded an excellent customer service experience, with answers delivered in a timely, thoughtful, professional, and extremely ethical manner.

I am very glad to have found my TruSkin.

I've been using this facial serum for months. It does work but takes months to see results.
