Review: 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.
Review: NO BREAK OUTS! lightweight, non-sticky, and soothing! - I discovered this brand from my flight attendant friend coz her skin is so amazing that she doesnt even wear foundation!!! So I started using Mela B3 as part of my La Roche-Posay set, and this serum is the one I reach for every morning and night. My main concern was that my skin got darker from constant sun exposure while cleaning our pool in the Florida heat. And this brand is really helping me to bring back my lighter skin!!! What I like about Mela B3 is that it feels lightweight, non-sticky, and soothing. No burning, no stinging, and no breakouts which was my biggest worry. It layers well under my other la roche serums and moisturizer, and after a few weeks, I’ve noticed my skin tone looks more even and some areas of discoloration are starting to fade!!! The only negative is the price, but for something that works gently and doesn’t upset my skin, it feels worth it!!! So these are my 4 la roche set •C12: Brightens and smooths skin, protects against environmental stress. •Mela B3: Targets dark spots and evens skin tone. •Hyalu B5: Hydrates, plumps, and softens fine lines. •Hydraphase: Restores moisture and brightness for smooth, fresh skin About the seal and authenticity I was bothered of not having seal so I made a research and found this •No, not every La Roche-Posay product is sealed some come simply in a box with no wrapping or seal. • Yes, some items feature protective elements like QR codes or holograms for authenticity. • Packaging styles can differ depending on the product type and region. If you’re ever unsure, you can usually check authenticity by scanning the QR code (when present) or verifying the product through their official website or app.

### ⭐⭐⭐⭐⭐ Best OTC Melasma Serum I've Tried
*by L***. on December 16, 2025*

I have very stubborn deep dermal melasma from hormones (not surface-level "sun spots") and this is, by far, THE most effective over-the-counter melasma serum I've tried. And I've tried A LOT of them, some costing 4 times as much. After cleansing, I start with Vitamin C to boost my sunscreen efficacy, then I layer this over it about a minute later. Since it has hyaleuronic acid in it, it's a wonderful twofer of skin plumping/extra hydration and dark spot treatment. Then I do my day moisturizer and SPF and I'm all set. I did notice, with my very, very critical eye, that after 1 or 2 days of using this serum, my spots were inarguably lighter. Nothing else I've tried for dark spots has worked as quickly -or- as well. It's going to be in my ride-or-die in between my twice-yearly cycles of prescription hydroquinone cream. Does it fade spots completely? No. Nothing does. Not even (for me) prescription hydroquinone or Tri-Luma. But this sure as heck helps! Plus it smells nice.
