L. a. Roche-Posay Natural 10% Diet C Serum For Face With Hyaluronic Acid & Salicylic Acid

Excellent!
This is an excellent product! In less than a month this product has already made a noticeable difference in the appearance of my skin. It’s light, dries quickly and has a nice light scent. I highly recommend.

Bottle has to be redesigned
I am 1/2way through the bottle so I honestly can not say if the serum is working or not. The scent is nice and the texture is beautiful. Very easy to apply the recommend 4 drops to my my entire face. I have sensitive skin and this product does not irritate me at all. I expected a little redness or stinging. I like to start slowly with new skincare items so I used every other morning for a week and now I faithfully use every morning. I actually look forward to it because of the texture and how well it absorbs into my skin. I follow with La Roche-Posay moisturizer 3 minutes after applying.Other comments mentioned the size of the dropper vs the size of the bottle opening. They are 100% correct. The serum is thick. When returning the dropper to the bottle it’s almost impossible to get the dropper in cleanly. The product gets on the threads of the bottle and it inevitably gets gummy and dirty. One person who commented said that this isn’t a problem because she wipes the dropper on her face to apply the amount of serum she needs. I wouldn’t recommend that because no matter how well you wash your face there are still germs and bacteria on your skin that will get transferred to the contents in the bottle where they will grow and cause skin issues. A dropper should never tough your skin or another surface before returning it a bottle. I do take the time to clean the threads on the bottle and dropper but I feel like I’m spending time doing something I shouldn’t have to. I probably won’t buy again unless the packaging concerns are addressed.

Great serum
I got this serum over Black Friday. Who knows if any of these products really work, but this smells great and does have a nice coverage before other moisturizers. It does not pill under my moisturizer. I will try again next time I need a Vitamin C serum.

Disappointing Experience with Vitamin C
I recently tried a Vitamin C serum with high hopes of achieving radiant and youthful skin. However, I must admit that the product did not live up to my expectations, and I found it rather underwhelming.Firstly, the effectiveness of the Vitamin C serum was questionable. Despite using it consistently for several weeks, I didn’t notice any significant improvements in my skin’s appearance. I had hoped for a brighter complexion, reduction in dark spots, and improved overall texture, but unfortunately, the results were minimal at best. It was disappointing to invest time and money into a product that failed to deliver noticeable benefits.Additionally, I found the quality of the serum to be lacking. The formula felt sticky and took a long time to absorb into my skin, leaving a residue that made it difficult to apply other skincare products afterward. I also noticed a slight tingling sensation upon application, which made me question the product’s compatibility with my skin type. Furthermore, the packaging was not very user-friendly, as the dropper dispensed too much product at once, causing wastage.Moreover, I was disappointed by the stability of the serum. Over time, I noticed the serum started to change color and develop a slightly off-putting odor, indicating a loss of potency. This raised concerns about the product’s shelf life and whether I was getting the full benefits of the Vitamin C.Finally, the price of the serum seemed excessive considering the lackluster results and overall experience. I had hoped to invest in a high-quality product that would deliver noticeable improvements, but unfortunately, this serum fell short of my expectations.In conclusion, my experience with the Vitamin C serum was disappointing. The lack of effectiveness, subpar quality, stability issues, and high price point make it difficult for me to recommend this particular product. I will continue my search for a Vitamin C serum that provides more significant results and a better overall experience for my skincare routine.

Esperé 20 días para dejar mi opinión y ahora que ya llevo usándola puedo decir que me ha dejado la piel muy luminosa. Yo ya he usado otros serums de vitamina c y este me ha gustado por su consistencia un “poco cremosa” se siente la piel muy hidratada y al instante te deja un glow muy bonito. Eso sí úsenla sin miedo porque se oxida rápido. Yo la comparto con mi esposo para así no esperar los 2 meses que tiene de caducidad. Tiene un ligero aroma así que ojo con las pieles sensibles

Le produit est bien, par contre j’ai trouvé le même beaucoup moins cher en parapharmacie (différence de 12€+-)
