Corthe Dermo Bright Toning Lumedic

• Niacinamide — Inhibits the transfer of melanin to the skin surface and strengthens the barrier simultaneously — one of the most well-supported daily brightening actives for consistent tone correction without irritation
• Licorice Root (Glabridin) — A dual-action brightening botanical that directly targets existing discoloration while inhibiting tyrosinase activity to prevent new melanin overproduction — one of the most effective natural brightening actives available
• Sodium Ascorbyl Phosphate (Vitamin C) — A stabilized Vitamin C derivative that suppresses melanin formation, neutralizes the oxidative stress that triggers pigmentation, and contributes visible luminosity with consistent use
• Houttuynia Cordata Extract — A Korean botanical with documented antioxidant and clarifying properties that supports skin clarity and provides additional defense against the environmental triggers of hyperpigmentation
• Ceramide NP — Reinforces barrier integrity throughout daily active brightening — ensuring the skin never becomes compromised or reactive during the correction process
• Panthenol — Soothes, softens, and maintains barrier comfort throughout daily brightening use — the active skin comfort agent that makes this toner appropriate for sensitive and reactive skin

Apply a nickel-sized amount to clean, dry skin after cleansing. Follow with serum, cream, and SPF in the morning. Use daily for best brightening results.

• How is a brightening toner different from a brightening serum?
  A brightening serum delivers concentrated actives at a single point in the routine. A brightening toner delivers active correction at the very first treatment step — on freshly cleansed, maximally receptive skin — and simultaneously prepares the skin to absorb every brightening active that follows more deeply and effectively. Used together, a brightening toner and serum create a multi-layer correction protocol where the toner begins the melanin suppression process and the serum continues it at higher concentration — producing significantly faster and more comprehensive results than either product alone.
• How long until I see visible brightening results?
  Initial improvements in skin radiance and surface clarity are typically noticeable within the first one to two weeks of consistent twice-daily use. Meaningful fading of dark spots and post-inflammatory marks develops over four to six weeks — with the most significant and lasting tone correction accumulating over eight to twelve weeks of dedicated daily use. Consistent SPF is the factor that most determines the speed of visible results.
• Is this suitable for sensitive skin?
  Yes — Ceramide NP and Panthenol are incorporated specifically to maintain barrier comfort and skin tolerance throughout daily active brightening use. The brightening actives are selected for their efficacy and tolerability profile — Niacinamide, Licorice Root, and stabilized Vitamin C are among the gentlest and best-tolerated brightening actives available. Those with very reactive skin should patch test before first full-face use.
• Can I use this alongside the KrX Mela Defense Whitening Cream?
  Yes — they are highly complementary. The Corthe Dermo Bright Toning Lumedic begins active melanin suppression at the toning step via Niacinamide, Licorice Root, and stabilized Vitamin C. The KrX Mela Defense Whitening Cream continues and deepens the correction at the moisturizer step via Tranexamic Acid and Niacinamide. Used together morning and evening they create a comprehensive multi-step brightening protocol that addresses pigmentation at every layer of the routine simultaneously.
