“Spectacular results” Love it ❤️❤️
I have to share this with you!!!!!. This is my 5th bottle, and I can honestly say I’m beyond impressed with the results. At first, I had my doubts, but this product has truly exceeded my expectations. I’ve seen amazing improvements, especially on my décolletage area, which used to be one of my biggest insecurities. The appearance of dark spots and uneven tone has consistently improved over time, and my skin now looks much more even and radiant. I use it every night before going to bed, and on alternating days I also apply it in the morning, always followed by sunscreen. This routine has made a huge difference. The texture is silky and not sticky at all, and it has a very delicate, pleasant scent, which makes it even more enjoyable to use. If you’re dealing with sun spots or discoloration like I was, this product is definitely worth trying. I’m extremely happy with the results and will absolutely keep repurchasing!

My second bottle! Repurchased because it actually works on acne scars
This is my second time purchasing this serum, and I absolutely love it! I used to use the previous La Roche-Posay formula, but this new Mela B3 version is fantastic. It has noticeably improved the appearance of my skin and has done wonders for my past acne scars and dark spots. It’s gentle, absorbs beautifully, and delivers real results. If you are struggling with post-acne marks, this is worth every penny. Highly recommend

Luxurious and comfortable. Highly recommend!
Magical. I recently saw a dermatologist regarding my middle aged face. She sent me out the door with a few samples of this and a few samples of sunscreens. Loved them all. But this. Wow. If you are treating your skin with prescriptions that cause redness or dryness but you must push through to see the results you want- use this too! Cicaplast B5 and this magical serum will have your skin feeling soft, smooth, moisturized and a whole lot happier. Initially, smoothing this into my skin feels luxurious and lovely. The serum moves easily, absorbs and feels hydrating. Immediately, my skin is happier. It’s even happier 20 minutes later. I put this on while getting ready for bed and in the morning after washing my face. 1 week in and I think there is a visible difference. I am using four new products on my face to help with the case of Getting Old and this is one of them. Cicaplast B5, a sunscreen and face wash- from this brand, La Roche-Posay. I never tried them till the dermatologist recommended and this brand seems fantastic. The dermatologist I saw was younger than me but her skin was amazing. She glowed and her skin was translucent and utterly blemish free. I was listening to everything she said and La Roche-Posay was her favorite brand for herself and to recommend. What else does she do to keep her skin supple and radiant? I should have asked! My skin has improved and I am buying another bottle for a friend and probably for my Mother. I do have sensitive skin (Oil of Olay moisturizer used to turn my face red and burn like fire). La Roche Posay products have been excellent and irritant free. Recommended! Try it. It’s good. (I have tried Chanel’s La Blanc line. Lancome. Philosophy. Murad. I like the La Blanc face wash and everything Shiseido. Everything else was forgettable and ineffective.) The La Roche Posay products I have used make me curious to try more of their products.

Great serum, but pricey and runs out quickly
This item is great, but it is definitely pricey, and you go through the bottle pretty quickly. At first glance, the bottle looks like it contains a good amount, but it’s important to realize that it is only about 70% full and not filled to the top. That said, the consistency is really nice. It has a pink serum-like texture, and after using it for two months, I’ve noticed that it has helped my skin look more glowy and healthy. I would recommend it, but just keep in mind that it is expensive.

Easy for use
Gentle and lightweight serum that helps brighten skin and fade dark spots over time. Great for sensitive skin and daily use, but results are gradual.

Doesn't correct dark spots, but helps reduce acne
Serum doesn't work well at correcting dark spots. I used this for over 4 months and no difference. It also has a strong floral scent, so if your sensitive to that sort of thing, you might want to find a different brand. The only thing positive about this is it cleared up my acne! I would get a couple zits here and there but now have a clear complexion. I stopped using this for about 2 weeks last month and proceeded to get a breakout. Yay

This does fade spots
I have been using this for about a month 2 times a day and am seeing the dark spots fade. It does have a pleasant scent and feels nice on the skin. I will continue to use in hopes my spots completely vanish. It is not cheap, but I am seeing results.

Elimina las manchas
buen producto, si ayuda a eliminar las manchas, aunque no es rápido, se siente un poco grasoso al momento de aplicarlo, se absorbe rapido

OK.
Bon produit, agréable na pique pas ma peau sensible mais efficacité il faut voir dans la durée, trop court pour juger les résultats. Un petit bémol: le carton d'emballage est arrivé éclaté. C'était pour moi donc pas grave mais si vous achetiez pour offrir ça peut poser des problèmes.

Per le macchie della pelle
È un ottimo prodotto per togliere pian pianino le macchie della pelle, costa sicuramente un po’ ma il tempo è davvero efficace
