  • Great product amazing quality
Size: 1 Fl Oz (Pack of 1)
Love this La Roche-Posay Hyaluronic Acid Serum! I use it 4 times a week and my skin is obsessed. Super hydrating, gives me a glow, and absorbs fast - perfect under makeup! Even gentle on my sensitive skin. Definitely recommend!

  • Amazing Serum
Size: 1 Fl Oz (Pack of 1)
Let me start off by saying, that I hardly ever write reviews on anything I buy on Amazon. HOWEVER, I only write reviews when something is phenomenal, like this product. This serum is amazing. I've tried every Hyaluronic serum out there, from the inexpensive to the expensive to the very expensive. I am big into skin care. This serum tops them all!!!!! From the moment I put it on, it immediately left my skin hydrated, soft and looking fabulous!!! BEST SERUM EVER!!!!! ... show more

  • Gives awesome moisture filling for long time
Size: 1 Fl Oz (Pack of 1)
One thing which I didn't like, the original packing was teared down. So it couldn't be a gift at all!!! But effect after this is amazing! Skin feels like really soft. No feeling of dryness or tightness. Recommend it!!!

  • Strong fragrance
Size: 1 Fl Oz (Pack of 1)
This is a nice serum but it has very strong floral fragrance that does not go away. If you don’t like strong floral fragrance on your face I would recommend not to get this one.. I like the serum but will it repurchase due to the smell.
