I am 37 years old and have been using this specific serum for several months now every night, without seeing any difference in relation to expression wrinkles... I would not buy it again.

The product was received by me in a set packaging with products from the Hydragenist range by Lierac that I use. After using one ampoule, I consider it to be one of the most effective products I have tried. It contains Bakuchiol, which acts similarly to retinol as an ingredient but does not have the unwanted side effects on sensitive and intolerant skin. My own skin is considered sensitive with a tendency for redness and acne, and I say tendency because it is improving during this period. I immediately noticed smoothing and a sensation of skin restoration because it immediately became firmer, healthier, and more even in texture and tone. There was no irritation, and I felt quite pleased with the result that came relatively quickly since it is a treatment. Excellent product. I wouldn't say that the fact that it contains fragrance is a reason to deduct stars. PS: However, we should definitely not forget the sunscreen the next day.

Although I am very satisfied with lierac products, this particular one caused me intense irritation in various areas of my face and eczema that lasted for days. Because it came in the packaging of another product I purchased as a gift, it did not include a leaflet for me to identify the ingredient that may have bothered me. Unfortunately, I couldn't continue using it to see its effectiveness. Only 3 stars because it is lierac.

I am 40 years old and I have deep expression lines around my lips. Honestly, it did the job for me, not that they completely disappeared but it is the only serum I have tried so far and I saw a difference... I am trying to treat them, even if I can only do it three times a year...???? I am very satisfied.
