I picked this up as a gift for my mom who has entered her 60's recently. She only recently started to get hyper-pigmentation on her skin and this product took care of that and then some. It has left her skin feeling visibly smoother and plumped up the area around her lips and orbital bone. Highly recommend it to ladies in their late 50's and in combination with the cleansing balm.

This is great for gentle resurfacing, even for the more mature skin. It gives you great glow, clarity and helps with pigmentation. Great value for money, as this 50ml. The only reason I gave it four instead of five stars is that it's not as strong as I am used too- but please keep in mind I've been using acids for twenty years and have developed a tolerance for high concentrations. I wouldn't call this a starter product, as it is very effective. But it certainly could be an excellent introduction to acids, as it treats your skin very gently.

Love this product. It really works with the skin! Would really recommend! Don't overuse it though. Can damage the skin.

This is targeted towards mature skin but I'm in my twenties. I have imbalanced oily skin. I feel like this did help with my oiliness and also left my skin tighter, soft, bouncy, like a cushion. I really like the results, very pretty. This does smell very potent but does not irritate sensitive skin.

I have found my holly grail product. I never review products simply because I have a problematic skin that takes to long to explain but this product deserve it! I literally seen results after the first use. My skin is happy and bright. It's like a baby's newborn face. My review is not enough for this product. I must admit that for me, personally, all the products from Alpha-H have instant effects. Worth all the money.

I use this on alternative evenings and it makes a big difference to my skin by the morning. For example, I went to bed with some irritation pimples last night (from a too heavy product) and woke this morning to almost all but the worst one gone, and that one was flat and faded. Overall tone is improved, red patches less obvious and much smoother. It really delivers on every promise.

This Concentrate is amazing and does everything it claims to. From the first use I noticed that my skin tone improved so did the texture and my skin was incredibly soft! The only thing though is that if you're in you 20s like I am, you don't need it. It is plumping and I have a full face which made my face even fuller and plumper which I didn't like. But for older and duller skins it will be amazing and you will love it. There should be more reviews for this amazing product but no one talks about it for some reason.

This is just incredible stuff - it doesn't actually feel like you're putting enough on but I assure you the three drops they recommend is enough to achieve results overnight. I am hooked and find that the best combination is with the anti-ageing balm from the same range. My skin has never looked better and my skin is pretty good so it really is a 'wow' product if I notice real results!

Great product, visible results in improving skin texture, smoothing small lines, scars, imperfections, inflammation is gone etc. Due to acids in it I was careful at first but now I use it twice a day. I've ordered it 5 times already.
