GH NAM-TD Serum: the benchmark depigmenting trio to fight dark spots from every angle

Skin spots have multiple mechanisms: excess melanin production, melanosome transfer, inflammation and accumulated sun damage. To treat them effectively, you need to act on all those fronts at once. GH NAM-TD Sérum by Gema Herrerías combines the most scientifically validated active trio for depigmentation — niacinamide, tranexamic acid and a vitamin D3 analogue — at the most effective concentrations, adding baobab oil to enhance tolerance and antioxidant action. The result is a total depigmenting serum that can be used morning and evening, all over the face or locally, suitable for most skin types.

Action and Benefits

• Reduces the intensity and extent of sun spots, melasma, post-inflammatory hyperpigmentation and lentigines.
• Prevents the appearance of new spots by inhibiting melanin synthesis through multiple pathways.
• Evens skin tone, improves luminosity and reduces redness with continued use.
• Improves the skin barrier, increasing tolerance to depigmenting actives.
• Antioxidant and anti-inflammatory action: protects against UV damage and prevents radiation-induced pigmentation.
• Anti-ageing properties: improves firmness and reduces the appearance of wrinkles.
• Non-comedogenic. Suitable for all skin types; use with caution on very sensitive skin. Formulated at pH ~5.9.

Key Active Ingredients

• 5% Niacinamide (Vitamin B3): multi-mechanism depigmenting agent: inhibits melanosome transfer from melanocyte to keratinocyte, reduces post-inflammatory hyperpigmentation and regulates sebum production. Antioxidant, anti-inflammatory and repairing action. Improves redness appearance and acts in synergy with tranexamic acid.
• 2.5% Tranexamic Acid: clinically proven depigmenting agent. Acts by competitively inhibiting tyrosinase and blocking the plasminogen/plasmin pathway, reducing pro-inflammatory mediators of UV-induced hyperpigmentation. Particularly effective for melasma. Also improves the skin barrier and has anti-ageing properties.
• 1% Vitamin D3-like (Saccharomyces/Grape Ferment Extract): biotechnological vitamin D3 analogue that stimulates VDR proteins responsible for adaptive immunity and cell differentiation. Improves the skin barrier for better tolerance to depigmenting actives, and has antioxidant and anti-inflammatory properties against UV radiation damage.
• 1.5% Baobab Oil (Adansonia Digitata Seed Oil): oil from the "tree of life", rich in palmitic acid, oleic acid, linoleic acid, β-sitosterol and γ-tocopherol. Powerful antioxidant and hydrating action that enhances tolerance and efficacy of depigmenting actives.

How to Apply

• Apply morning and/or evening to clean, dry skin until fully absorbed.
• Can be applied evenly all over the face or locally on the spot.
• For intensive treatment, apply morning and evening.
