Is La Roche-Posay Mela B3 Serum right for your skin?
Best for
- Dark spots and sun spots that have built up over time
- Post-acne marks that stay brown or dark long after a pimple has gone
- Uneven-looking tone and patchy pigmentation on brown and medium skin
- Anyone already wearing daily sunscreen who wants a targeted dark-spot step
Skip it, or patch-test first, if
- You want skin lightening or a fairer complexion: this serum targets the look of dark spots, it does not change your natural skin tone
- You have diagnosed melasma or pigmentation that keeps spreading: see a dermatologist, and use this only as part of the routine they advise
- Your skin is very sensitive or reactive: patch-test on the jawline for a few days first
- You will not wear sunscreen every day: without it, new dark spots keep forming
How do you use La Roche-Posay Mela B3 Serum?
Morning
- Cleanse and pat your skin dry.
- Apply a few drops of Mela B3 over the face, or press it onto areas with dark spots.
- Follow with a light moisturiser.
- Finish with a broad-spectrum SPF50+ sunscreen such as La Roche-Posay UVmune 400 Invisible Fluid.
Evening
- Cleanse to remove sunscreen and makeup.
- Apply a few drops of the serum on dry skin.
- Finish with your moisturiser.
Dark spots fade slowly, so use it every day for several weeks before judging it. Sunscreen is part of the routine, not optional: reapply when you are outdoors.
What are the key ingredients in La Roche-Posay Mela B3 Serum?
- Melasyl — La Roche-Posay's patented dark-spot ingredient, developed to target the look of excess pigmentation
- Niacinamide (vitamin B3) — helps tone look more even and supports the skin barrier
Is Mela B3 a whitening serum?
No. Mela B3 is a dark-spot serum, not a whitening or fairness product. It targets the look of patches that are darker than the rest of your skin, such as sun spots, post-acne marks and uneven pigmentation, so your tone looks more even. It does not change your natural skin colour, and it is made for all skin tones, including brown skin. For it to work, daily sunscreen is essential, because sun exposure keeps creating new dark spots.
La Roche-Posay Mela B3 Serum vs CeraVe Retinol Serum: which should you choose?
| La Roche-Posay Mela B3 Serum | CeraVe Retinol Serum | |
|---|---|---|
| Main active | Melasyl, niacinamide | Encapsulated retinol, niacinamide |
| Main goal | Dark spots and uneven-looking tone | Texture, post-acne marks, pores |
| When to use | Morning and/or evening | Evening only |
| Start slowly? | Patch-test, then daily | Yes, 2–3 nights a week |
| Daily sunscreen needed? | Yes | Yes |
Choose Mela B3 if dark spots and uneven tone are your main concern. Choose the CeraVe Retinol Serum if rough texture, pores and post-acne marks matter most and you are ready to start retinol slowly. Some people use Mela B3 in the morning and retinol at night.
How can you tell if your La Roche-Posay Mela B3 Serum is original?
- The serum should be a smooth, light liquid that spreads easily and absorbs without grit or separation; a thick, oily or strangely coloured liquid is a warning sign.
- The box should be sealed, with the La Roche-Posay and Mela B3 names and the ingredient list printed clearly; blurred print or spelling mistakes suggest a copy.
- A price far below other trusted sellers usually means old stock or a fake.
- Check the batch code printed on the box and the bottle: the two must match, and the code should look printed, not stuck on. Every unit we sell is batch-code checked on arrival in Seoul, and we verify any code for free — see how to check if Korean skincare is original.

La Roche-Posay Mela B3 Serum: frequently asked questions
Is the La Roche-Posay Mela B3 Serum at Korean Skincare Pakistan original?
Yes. Korean Skincare Pakistan is the authorised e-commerce retailer of the official distributor of L'Oréal Group in Pakistan, and La Roche-Posay is a L'Oréal brand. Every unit is batch-code checked on arrival and shipped from our Seoul warehouse. If a product is ever not original, an old batch or near expiry, you can return it free within 7 days.
Is Mela B3 the same as La Roche-Posay Retinol B3 Serum?
No. They are two separate La Roche-Posay serums. Retinol B3 is built around retinol and is aimed mainly at fine lines and texture, used at night. Mela B3 is built around Melasyl and niacinamide and is aimed at dark spots and uneven-looking tone. Check the name on the box: this page is for Mela B3.
Is Mela B3 good for post-acne marks?
Yes, the brown or dark marks left after pimples are one of the main things it is made for. Use it daily and protect your skin with sunscreen, because sun exposure makes these marks darker and slower to fade. It is not a spot product for active pimples, so keep your acne products in the routine.
Should I use Mela B3 in the morning or at night?
You can use it in the morning, at night or both. In the morning, apply it after cleansing and before moisturiser, then always finish with a broad-spectrum SPF50+ sunscreen. If you use retinol or exfoliating acids at night, many people keep Mela B3 for the morning and the stronger active for the evening.
Can I use Mela B3 with vitamin C or retinol?
Usually yes, but add one new product at a time. A common routine is Mela B3 in the morning under sunscreen and retinol at night. With vitamin C, apply the thinner serum first and let it absorb before the next. If your skin becomes red, dry or stings, cut back and use fewer actives.
Is Mela B3 suitable for brown skin and melasma?
It is made for all skin tones, including brown skin, which is more prone to long-lasting dark marks. For melasma, it can be part of a routine, but melasma is a medical skin condition that needs strict sun protection and often a dermatologist's plan. Use daily SPF50+ sunscreen and see a dermatologist if patches keep spreading.
