ISDIN Melaclear Advanced Dark Spot Correcting Serum Eco-Refill 1.7 fl oz — Tranexamic Acid & Niacinamide for Brightening

ISDIN Melaclear Advanced Eco-Refill is a lightweight serum that helps reduce the appearance of dark spots and evens skin tone with tranexamic acid, niacinamide and exfoliating acids.

This eco-refill version of Melaclear Advanced delivers the same pigment-correcting formula in a sustainable format. Formulated in Spain, the silky gel-serum blends tranexamic acid to address sun-related discoloration, niacinamide for barrier support and tone refinement, plus a gentle mix of exfoliating acids to accelerate surface renewal. Daily use can reveal visible improvements within weeks while maintaining hydration and skin comfort.

How quickly can I expect to see improvements in dark spots?

Results vary by skin and spot severity, but many users notice initial brightening within two weeks and more pronounced improvement around 8–12 weeks of consistent application. Consistent morning and evening use, sun protection, and following product directions improve outcomes.

• Visible start: often within 2 weeks
• Notable change: commonly by 8–12 weeks
• Best with daily SPF in the morning
• Apply to clean, dry skin for optimal absorption

What active ingredients make this serum effective?

The formula combines tranexamic acid to help counteract sun-induced discoloration, niacinamide to refine skin tone and strengthen the skin’s surface, and gentle exfoliating acids that encourage cell turnover. Together these actives aim to reduce pigment fragmentation while keeping skin hydrated.

• Tranexamic acid: targets pigmentation pathways
• Niacinamide: evens tone and supports barrier function
• Exfoliating acids: promote surface renewal and smoother texture
• Silky gel-serum base: quick absorption and comfortable wear

How do I fit the eco-refill into my skincare routine?

Use the serum after cleansing and any water-based treatments, both morning and evening. Follow with moisturizer; in the morning always finish with a broad-spectrum sunscreen to protect results and prevent new discoloration.

• Step 1: Cleanse and pat dry
• Step 2: Apply Melaclear Advanced to areas with discoloration
• Step 3: Layer moisturizer, then SPF in the morning
• Use consistently for best long-term improvement

Is this serum suitable for sensitive or all skin types?

The product is dermatologically tested and designed for a range of skin types, including sensitive skin, thanks to its soothing and hydrating components. Patch testing is recommended if you have very reactive skin, and introduce any exfoliating actives gradually.

• Dermatologically tested formula for multiple skin types
• Hydrating niacinamide helps reduce irritation risk
• Start with less frequent use if you’re reactive
• Combine with gentle cleansers and sun protection
