- Reviewed in the United States on January 8, 2025Size: 1 Fl Oz (Pack of 1)Verified PurchaseThe La Roche-Posay Mela B3 Serum has quickly become a staple in my skincare routine! It delivers visible results, feels luxurious, and is gentle enough for sensitive skin.
Effective Dark Spot Corrector
I’ve been using this serum for a few weeks, and the difference is noticeable. My post-acne marks and sunspots have visibly lightened, and my overall skin tone looks more even. The 10% niacinamide and Melasyl formula truly work wonders without being harsh.
Anti-Aging Benefits
Not only does this serum target discoloration, but it also leaves my skin looking smoother and more radiant. Fine lines are less pronounced, and my skin feels plumper and healthier. It’s a multitasking powerhouse!
Lightweight and Non-Greasy
The texture is lightweight, non-greasy, and absorbs quickly, making it perfect for layering under other products or makeup. It doesn’t leave any sticky residue, which is a big plus for me.
Gentle on Sensitive Skin
As someone with sensitive skin, I appreciate that this serum is fragrance-free and formulated for all skin types. I experienced no irritation or redness, even with daily use.
Perfect Stocking Stuffer
At 30ML, the size is perfect for gifting. It’s a thoughtful stocking stuffer for anyone into skincare or looking to combat dark spots and uneven skin tone. The sleek packaging adds a touch of luxury to the gift.
Final Thoughts
The La Roche-Posay Mela B3 Serum is worth every penny. It’s effective, gentle, and delivers real results. Whether you’re dealing with sunspots, age spots, or acne marks, this serum is a must-try. I’m already planning to repurchase when I run out!
Pro Tip: Pair it with sunscreen during the day to protect your skin and enhance the results!
- Reviewed in the United States on February 13, 2025Size: 1 Fl Oz (Pack of 1)Verified PurchaseI recently started using the La Roche-Posay Mela B3 Serum alongside the La Roche-Posay Mela B3 Gel Cleanser, and I can already see a significant difference in my skin!
-Mela B3 Serum Review:
This serum is a game-changer for anyone struggling with dark spots or uneven skin tone. It has a lightweight texture that absorbs quickly and leaves my skin feeling hydrated without any sticky residue. The blend of melasyl and niacinamide works wonders for brightening my complexion and reducing the appearance of fine lines. After just a few weeks of consistent use, I’ve noticed my dark spots are fading, and my skin looks more radiant and youthful.
-I recommend to paire with the Mela B3 Gel Cleanser, this duo creates an effective routine. The gel cleanser is gentle yet effective, removing impurities without stripping my skin of moisture. It preps my skin perfectly for the serum, enhancing its absorption and overall effectiveness.
Using these two products together has truly elevated my skincare routine. The cleanser sets the stage for the serum, allowing for maximum absorption and results. I love how my skin feels clean, refreshed, and ready to soak up all the benefits of the serum.

My skin is soft and has a glow. I get compliments from my friends on how my face has toned up. Will definitely continue to use. You just have to wear the sunscreen and stay consistent.
- Reviewed in the United States on April 22, 2025Size: 1 Fl Oz (Pack of 1)Verified PurchaseI’m not seeing results yet but I’ve only been using a week and a half my dark spots are really dark on my legs so it may take another bottle to see some change, it goes on easily the dropper only lets you get a small amount but it spreads so easily it keeps me from wanting to much on too much lol
- Reviewed in the United States on April 13, 2025Size: 1 Fl Oz (Pack of 1)Verified PurchaseGood product. Feels good on skin. My skin is sensitive and this product worked well. I would buy again. Light to wear. Easy to apply, moisturizing and definitely a great buy for the money.
- Reviewed in the United States on April 12, 2025Size: 1 Fl Oz (Pack of 1)Verified PurchaseI am very impressed with this product!!! It actually worked for my dark spots/age spots on my face and continues to noticably lighten them. I've been using it for a month!
- Reviewed in the United States on April 10, 2025Size: 1 Fl Oz (Pack of 1)Verified PurchaseSkin Feels soft after using it, light on skin, easy application I see a little difference, I feel like my skin is breaking out though . It's been almost a month now
- Reviewed in the United States on April 3, 2025Size: 1 Fl Oz (Pack of 1)Verified PurchaseI’ve used this product for about 3 weeks and I am seeing great results on an age spot on my face that was the size of a dime - it is now smaller and I think will eventually go away- also putting it on tops of my hands where I have age spots and seeing a real difference- one spot was very dark but small- it is now even smaller and much lighter - highly recommend- I had a quote to have the spot in my face removed for $4000! Glad I just got this instead
