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 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.

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 started using DuoGen [Formerly Habitual Skin] care products a couple of months ago and I love them. They are the best products I have ever used and have totally transformed my skin. I keep getting comments that imy skin is so glowing.

Hydration is the most important step in the anti-aging battle. Wonderful product. I use this product day and night.
Anita B. 5/5 Verified
My skin was looking very tired and ruddy. I started using the DuoGen [Formerly Habitual Skin] skin care line and my skin has improved significantly. I am a lot older than I look thanks to these products!
Jeanean G. 5/5 Verified
Highly recommend. I love these products. They have reduced the lines between nose & mouth & side of lips and also between my eyes. Not gone completely but then I am 66 & will never look 20 again. The best result is the crows feet around my eyes which can now hardly be seen - see pictures of me without make up. No good for reducing age spots though.
Janette F. 5/5 Verified
Since using this fabulous duo I feel my skin is much brighter and my skin looks a lot healthier I'll be 73 in January will keep ordering this duo, fine lines look better softer can't expect at my age for them to dissappear all together .

I'm 66 and these products are amazing. I will never get rid of the bags & creases at my age but they have reduced them considerably & made me feel more confident
Janette F. 5/5 Verified
Only been using a few weeks (5/6) so nothing amazing by view. My skin is hydrated but I'm afraid The Ordinary hyaluronic acid is a better product and we'll over half the price (£8)and just as pure. Sorry DuoGen [Formerly Habitual Skin] but you're prices are way too much
Vicky H. 4/5 Verified
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.

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

Kelly M. 5/5 Verified
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!

Meena S. 5/5 Verified
What can I say? It’s amazing and does seem to work like a dream. Only need the tiniest amount (and I use on a wet face which helps draw moisture into skin). My face really looks and feels fab!
