– Absolute Collagen Boosting Hyaluronic Acid & Bakuchiol Face Serum, Anti-Aging Serum for Wrinkles, Retinol Alternative for Youthful, Hydration & Radiance, Plump Skin, 30ml

Excellent product, I can already see a difference after 2 weeks of use, my skin looks amazing. Definitely recommend I’ve used clarins products do years but this is far more effective

Absolutely fantastic. Ive been using this product for a while now and can feel the difference on my skin. Plus it was a lot of cheaper from Amazon

A good product, leaves the skin hydrated and soft. It works best together with specific facial routine and moisturising cream after. A nice product, not a complete game changer but good on the skin

It’s more of a watery cream than a serum & absorbs well. It has a light pleasant smell. This is working for me, I’ve had compliments, my skin does look very good, better, fresher, glowing and I can’t believe I’m writing this but my skin does look a bit younger. I will continue using, I’m very happy and have just ordered the day cream. I’m very impressed with this product, it’s pricey but it lasts a while, I’m so glad I gave it a go.

Been using this for 2 months and it really has made a difference. I'm 57 and it truly has made a difference to my skin. It smells amazing which really is a nice thing to sniff in the mornings! It rubs in quickly, and spreads well, a little goes a long way. My skin appears to be plumper and fresher looking. I have had comments that I look "well"... sure they don't mean fat hahaha! So happy with this that I'm about to buy another one and looking at other products in the range.

Good product, skin feels soft after, but doesn’t last long and expensive product.

Good hydration, good quality, effective.

Awful. I don’t usually have sensitive skin, but I reacted badly to this. My face was burning and my skin felt hot, tight and itchy. I stopped using it for a couple of weeks and then tried again just in case I was imagining that it was the serum causing a reaction. I wasn’t imagining it. My skin felt terrible. It started burning and itching and the reaction lasted a few days. I’m going back to Liz Earle skin care- it’s gentle and my skin loves it.

I've been using this collagen for a couple of years and it's really good.

Très franchement, idéal : texture top, effet en deux jours, sans parfum aucun. Ai cessé un temps d'en mettre un temps pour voir si vraiment l'effet se voyait, : très clairement oui, depuis l'utilise toute l'année sans interruption !! Je l'applique le soir, et le Biotulin vit dans le frigo à plein temps ; j'utilise un autre produit le matin. Effets visibles en deux jours.

J ai acheté ce produit en espérant qu’il puisse réduire les cernes et lisser ma peau. Je n y croyais pas trop au départ .. mais au bout d’une semaine je remarque que ma peau est plus lisse et plus jeune..

J’ai l’impression que cela hydrate ma peau en profondeur. Cette dernière est plus lisse. Il faut vraiment mettre très peau d’huile. Je recommande ce produit malgré un prix qui peut sembler élevé... 👍
