Product Review: Biotherm Aquasource Deep Serum


I have read so many good things about the original Aquasource Super Serum, and out of desperation to get rid of the three dehydration lines on my forehead, I splurged and bought the newest version of this, now called Aquasource Deep Serum, which also came with a bonus gift set including two Blue Therapy products (to be reviewed separately). This retails at CAD$55.00 for 50ml, I believe the last version was CAD$49 for 30ml so you do get a bit more bang for your buck this time around.

From the Biotherm official website:

3x more concentrated in thermal plankton cellular water and mannose ( than aquasource) Aquasource deep serum is a deep moisture and light concentrate that leaves skin deeply bound with water: plump, fresh and silky.

From deep hydration, a new light is born!
The skin is deeply bound with water:

– Skin looks illuminated from within, full of life in 90% of women
– Skin looks more supple, revitalized, of better quality for 95% of women

A light, very refreshing fluid gel with beautifying rosy micro-pearls. The refreshing deliciously scented fragrance of Aquasource: with citrus top notes (mint, orange, lemon, mandarin, grapefruit), a floral heart (lily of the valley, jasmine) and musc base notes.


I believe, for a very long time, that Biotherm (owned by L’oreal) is clever in their marketing: the 5000 Litres of XXX in a bottle marketing really sells. It sounds great, and you know what? The scent they use – a clean, fresh marine fragrance – complements the claims. I have sensitive skin towards a lot of fragrances, but I never had a bad reaction from using Biotherm, and I rather like the Aquasource scent. It’s fresh and spa-like.

The texture is as described. One thing I add is that the product contains mica, which accounts for the pearlescent finish. It’s not really that shimmery mind you, but it does look good when you apply it on your bare skin. An optical trick.

I have been using this for about two months now, at twice a day, about a pump and a half each time and I still have a quarter of the bottle left. I don’t know why not a lot of companies manufacture a simple hydrating serum like this anymore, so to be honest I am happy just to have something like this to use for my dehydrated skin. My fine lines on my forehead (from dehydration) remain; but my overall complexion is much less dehydrated. In other words, this actually works, BUT not beyond the hydration. In other words, don’t expect this to do anything other than hydrate (well). It does not feel greasy and absorbs very quickly without any tight feeling or stickiness. It works perfectly under a primer for makeup to go on smoothly.

Will I repurchase? Most likely not. This is good if you are under 30 and not looking for anti-aging properties and simply want to hydrate your skin very well; but I need an anti-aging serum to smooth the fine lines on my forehead so I will probably move onto Clinique’s Repairwear.
