I have used this product for years now. As well as the Duo Gen Retinol Serum and Niacinamide moisturiser. The products make such a difference. There are many products on the market, promsing the earth but these do actually work for me. I dont mind paying slightly more if the product does what it says on the bottle!

I love the Hydrochloric Acid. I have been using for about a year or so now and I have noticed my skin has a clearer appearance and my wrinkles look so much better. I am fast approaching 60 (in March) I apply it on damp skin and a small amount goes a long way! I use it on my face and neck.

I love this duo! I’m new to this brand but, after doing some research, I thought I’d try it. My over 60 skin is glad I did, it beats most other brands I’ve tried. I leave a minute or two between applications of each product to allow them to sink in individually while brushing my teeth etc. and then follow with the day cream. I will be buying them again.

I have loved LOVED using the Hyaluronic Acid Serum. My skin is really glowing, I can see where it added moisture and hydrated the areas that need it...dare I say it's reinvigorated my cheek Filler also?!?! I definitely see more definition. I add a small amount on my lip before I put in lip balm at night and I've been asked if I've had my lips filled again! It's a great product without a million additional ingredients...I will definitely purchase again...it also lasts for ages.

This hyaluronic acid serum is excellent! I use it when coming out of the shower, while my skin is still damp. This serum works best in the steamy air of the shower. I use this hyaluronic acid serum on my face and then run my hands along my hands/arms to use up any excess product. I also use a pump of the serum on my just-washed hair to help seal in moisture.

Inhave been using skin care serums for around 1 year now and absolutely love them! I would never use anything else on my face. The products absorb so well and feel so velvety on my skin also they make my skin glow ✨️ which is amazing.

The best hyaluronic acid serum I have used. Has kept my skin in tip top condition. I am constantly being told I don't look my age.. I am 43. So this serum is a must in your life, to keeping that skin looking clear and wrinkle free.

I love my morning duo! I am 81 years old, so realistically do not expect this to rid me of my wrinkles, but I will explain it this way. Everyone has experienced a ‘good hair day’ which makes you feel confident and attractive and lifts your spirits, no matter what your age. Well, I use this night and morning (my choice) but after using it, and then applying my make up, I always experience a ‘good face day’!

I put in a Google search for the best Hyaluronic acid on Honest-Reviews.com and five came up, DuoGen [Formerly Habitual Skin] was number 1, since using the Hyaluronic acid morning and night and DuoGen [Formerly Habitual Skin] Retinol serum at night for the last five weeks my skin has never looked so good, it's firmer, the dry patches are gone and it's glowing, I will be buying the Triple Vitamin C serum next, I would highly recommend DuoGen [Formerly Habitual Skin] products.

Rolls off when I apply any product on top so I'm not even sure that it's doing anything? I do wait before applying the next layer. Also, the label hasn't lasted. Only had the product a short time and the label started peeling off onto my fingers, so have tiny flecks of green on my skin now too! I suppose I expected a bit more from such an expensive product. I'll finish the bottle but won't re purchase.

Ive been using these products for 6 months now. My skin is much softer, very few lines and firmer. Loving the comments from friends.
Christine H. 5/5 Verified
I'm 47 (in 3 days!) and I've been using this product for just over 4 months and I've noticed a real difference in fine lines around my eyes, forehead and around my neck. This photo was taken without any filters. It provides great hydration, I use it after toning and before my usual moisturiser. I've tried other more expensive brands, and I'm more than happy with DuoGen [Formerly Habitual Skin]!
Julie M. 5/5 Verified
Incredible difference within 3 days, I had no idea my skin was so dehydrated. No side effects, seeps in within seconds. I’m hooked.

Love this combination. The vitamin c Smells lovely and glides on your skin I have had many compliments on how good my skin is looking . I would say you will see a difference in about two weeks . I use the Vitamin c in the morning and the hyloronic acid at night under my night cream

I have been very poorly as the second Covid vaccine June 2021 caused an allergic reaction (urticuria) affecting the whole of my skin - the largest organ. I was fortunate that my face was not affected until January of this year when the burning itching and acne like spots affected all of my face, neck and upper chest. The serum helps with the very uncomfortable inflammation. I highly recommend this product.
Julie A. 5/5 Verified
First time actually looking after my skin and I love the product. Great service, speedy delivery. I will be back for more.
Philip P. 5/5 Verified
I think pictures speak louder than words. I'll be 61 this year. I've been using this HA for around a month & my crows feet are shrinking. Brilliant product. You only need a little, I bought the 3 bottles & they'll last me a VERY long time. I use 2 pea size pumps & it goes from my forehead right down over my chest. I love it already and the best thing is that it will only get better with regular use!! Win win.

As you can see I have alopecia universalis (as well as other auto-immune diseases 😩) I thought I would try your Hyaluronic Acid Serum to see if could help with my skin, and make me feel a little better about myself. I'm really happy to say it has, my skin feels ultra smooth and my deep frown marks and lines around my eyes look so much better 😊 I will be trying more of your products for sure👍 delivery was fast, all good.. Thank you

My skin drinks this serum . I use it under my normal moisturiser it’s like the glue ( not literally) that makes your moisturiser sink in and last .. Definitely the best brand I have used . So gentle no harsh ingredients.. Great also to support a independent company

Have used many hyaluronic acid serum including those very prestigious pricey skincare brands from around the world, I found DuoGen [Formerly Habitual Skin] is true rival to these famous brands. You’ll know why this brand doesn’t need any advertising after trying it because you can feel its superb performance after maybe a week’s usage depending on your skin condition. A very good product!

I am 55 & have the usual lines around my eyes for a woman of my age but was becoming increasingly upset at the lines around my lips. I bought the tripe pack of the DuoGen [Formerly Habitual Skin] Hyaluronic Acid Serum and can honestly say it is absolutely fabulous! I can see a big improvement in the skin surrounding both my eyes and my lips. Delighted with it, highly recommended & will be reordering!
