Trust & Pharmacist Advice
Hyperpigmentation can develop after sun exposure, inflammation, blemishes and other skin irritation. Consistent skincare and sun protection are important when trying to improve the visible appearance of dark marks.
From a pharmacy skincare perspective:
- Daily broad-spectrum SPF is essential when pigmentation is a concern.
- Apply sunscreen every morning even when using Mela B3 at night.
- Reapply SPF appropriately when outdoors for prolonged periods.
- Niacinamide is widely used in skincare for uneven-looking tone and skin-barrier support.
- LHA provides gentle exfoliating activity and may increase sensitivity in some users.
- Retinyl palmitate is present, so avoid unnecessarily layering multiple retinoid or exfoliating products if irritation develops.
- Introduce the serum gradually if your skin is very sensitive.
- Avoid picking or squeezing blemishes because this may increase the likelihood of post-blemish marks.
- Pigmentation improvement generally requires consistent use over time.
- Persistent, changing or unexplained pigmented lesions should be assessed rather than treated as ordinary dark spots.
- New, changing, asymmetrical, bleeding or irregularly pigmented lesions should receive medical assessment.
- Stop use if significant irritation, swelling or persistent burning develops.
Mela B3 is cosmetic skincare and should not be presented as treating melasma or another medical pigmentation disorder.
Not Suitable For
- Anyone with a known sensitivity to an ingredient
- Direct application into the eyes
- Significantly irritated or broken skin
- Those who experience persistent irritation from the formula
If you use prescription retinoids, strong exfoliating treatments or other intensive pigmentation treatments, consider pharmacist or dermatologist advice before combining multiple active products.
How to Use
- Cleanse and gently dry the skin.
- Apply 3–4 drops to the face, neck and décolleté.
- Use morning and/or evening.
- Follow with moisturiser if required.
- During the morning, always finish with a broad-spectrum facial SPF.
- Avoid direct contact with the eyes.
La Roche-Posay specifically recommends 3–4 drops morning and/or evening and daily SPF as the final morning step.

FAQs
1. What does La Roche-Posay Mela B3 Serum do?
La Roche-Posay Mela B3 Serum is designed to visibly improve dark spots and uneven pigmentation, including persistent pigmentation and post-blemish marks. It combines Melasyl™ with 10% niacinamide and additional ingredients including LHA, retinyl palmitate and hyaluronic acid. The formula helps improve the appearance of existing dark marks while promoting a more even and radiant-looking complexion. It is suitable for all skin types and tones, including sensitive skin.
2. What is Melasyl™ in Mela B3 Serum?
Melasyl™ is La Roche-Posay's pigmentation-focused active ingredient, listed in the formulation as 2-mercaptonicotinoyl glycine. According to La Roche-Posay, it interacts with excess melanin precursors before they contribute to visible pigmentation irregularities. It was selected following extensive research into pigmentation and is combined with 10% niacinamide in Mela B3 Serum to target the visible appearance of dark spots and uneven skin tone.
3. How much niacinamide is in La Roche-Posay Mela B3 Serum?
Mela B3 Serum contains 10% niacinamide, also known as vitamin B3. Niacinamide is widely used in cosmetic skincare designed for uneven-looking skin tone and skin-barrier support. In this formula it is combined with Melasyl™, LHA, retinyl palmitate and hyaluronic acid to provide a multi-ingredient approach to pigmentation, hydration and skin texture.
4. Does Mela B3 Serum help post-acne marks?
Yes. La Roche-Posay specifically identifies post-acne marks and post-inflammatory hyperpigmentation as concerns targeted by Mela B3 Serum. It is intended to help fade the visible appearance of stubborn marks and create a more even-looking skin tone. It does not treat active acne itself, so ongoing blemishes may require an appropriate separate skincare or medicinal acne treatment depending on severity.
5. Can Mela B3 Serum help sun spots and age spots?
The manufacturer specifically identifies sun spots and age spots among the pigmentation concerns for which Mela B3 is intended. The serum helps improve the visible appearance of these dark marks and uneven tone. Daily broad-spectrum sunscreen is essential when addressing sun-related pigmentation because continued UV exposure can contribute to new and recurrent dark spots.
6. Is Mela B3 Serum suitable for sensitive skin?
Yes. La Roche-Posay states that Mela B3 Serum is suitable for sensitive skin and all skin types and tones. The formula is non-comedogenic and dermatologically tested. Because it also contains LHA and retinyl palmitate, particularly sensitive users may still prefer to introduce it gradually and reduce frequency if they experience persistent dryness, redness or irritation.
7. How often should I use La Roche-Posay Mela B3 Serum?
La Roche-Posay recommends applying 3–4 drops morning and/or evening after cleansing. It can be used every day when well tolerated. Follow with moisturiser if needed. If applying it during the morning, always complete the routine with an appropriate broad-spectrum sunscreen. Customers with very sensitive skin may prefer to begin once daily or every second day and increase use according to tolerance.
8. Does Mela B3 Serum contain retinol?
The formula contains retinyl palmitate, a vitamin A derivative, rather than pure retinol as the principal active. La Roche-Posay groups retinyl palmitate with LHA as a gentle surface-renewal combination within the serum. If you already use a separate retinol, prescription retinoid or strong exfoliating treatment, introduce Mela B3 carefully to avoid creating an unnecessarily irritating routine.
9. Does Mela B3 Serum contain salicylic acid?
The formulation contains capryloyl salicylic acid, commonly known as LHA, rather than standard salicylic acid. LHA is an exfoliating ingredient used to support gentle skin-surface renewal. La Roche-Posay combines it with retinyl palmitate in Mela B3 to promote a more radiant and even-looking complexion. Those already using strong exfoliating acids should monitor overall skin tolerance.
10. Do I need sunscreen while using Mela B3 Serum?
Yes. Daily broad-spectrum sunscreen is one of the most important steps when managing visible pigmentation. La Roche-Posay specifically recommends applying SPF after Mela B3 during the morning and suggests combining it with Anthelios UVMune 400 sun protection. Continued UV exposure can contribute to pigmentation and make existing marks more persistent, so SPF should be considered an essential part of the routine.
11. How long does Mela B3 Serum take to work?
Results vary depending on the type and depth of pigmentation, consistency of use and sun exposure. La Roche-Posay reports that 94% of participants showed a clinical reduction in the overall area of dark spots after 12 weeks in an instrumental study involving 50 subjects. Consistent daily use alongside broad-spectrum sun protection is therefore more appropriate than expecting an immediate disappearance of pigmentation.
12. Can I use Mela B3 Serum with other skincare products?
Yes. It can be used after cleansing and before moisturiser and sunscreen. However, because the formula already contains LHA and retinyl palmitate, take care when combining it with additional retinol products, prescription retinoids or strong exfoliating acids. A simple pigmentation routine can consist of gentle cleansing, Mela B3 Serum, moisturiser where required and broad-spectrum SPF50 during the day.
