Skin-Nomad's Take — At a Glance

• 6% Tranexamic Acid, 10% Niacinamide, and Retinal in one evening brightening serum
• Three brightening mechanisms across the full melanin cycle plus retinoid renewal
• Fragrance-free; evening use; one of the most comprehensively active brightening serums available

The PURITO SEOUL TXA 6 Niacinamide 10 Retinal Serum addresses skin tone improvement at three distinct biological stages simultaneously: upstream melanin signalling (Tranexamic Acid), melanin distribution (Niacinamide), and accelerated surface cell renewal removing existing pigmentation (Retinal) — while Retinal's retinoid receptor activity simultaneously supports collagen synthesis and skin longevity. At 6% Tranexamic Acid, 10% Niacinamide, and stabilised Retinal, each active is present at a concentration where the peer-reviewed research for its mechanism demonstrates meaningful results. PURITO SEOUL is a Seoul-based brand founded in 2017.

Key Benefits

• 6% Tranexamic Acid for upstream melanin production inhibition: Disrupts the plasmin-mediated keratinocyte-melanocyte signalling pathway that instructs melanin to be produced in response to UV and inflammatory stimuli, addressing pigmentation at the production-signalling stage before melanin is synthesised.
• 10% Niacinamide for melanosome transfer inhibition: At 10%, inhibits the transfer of melanin-containing melanosomes from melanocytes to keratinocytes — addressing the distribution of already-produced melanin. Combined with TXA's upstream inhibition, the two actives cover both the production signal and the distribution pathway.
• Stabilised Retinal for cell renewal and skin longevity: Converts to retinoic acid in one step, delivering cell renewal stimulation, collagen synthesis, and accelerated surface turnover more efficiently than retinol at equivalent concentrations. Adds a third brightening dimension by accelerating the removal of melanin-loaded pigmented cells.
• Peptide complex for collagen support: Contributes collagen synthesis stimulation alongside Retinal's structural renewal activity, amplifying the skin longevity benefit.

Retinal is a retinoid. Use in the evening only. Follow with SPF50+ the next morning. Introduce gradually, starting every other evening. Not suitable during pregnancy or breastfeeding.

Ideal For

• Skin types: All skin types; introduce gradually for sensitive skin due to Retinal content.
• Skin concerns: Persistent hyperpigmentation, dark spots, post-blemish marks, uneven skin tone, loss of firmness, fine lines, dullness, and enlarged pores.

FAQ

Q: How do the three brightening actives work together rather than duplicating each other?
A: Tranexamic Acid blocks the signalling pathway that tells melanocytes to produce melanin. Niacinamide blocks the transfer of already-produced melanin to keratinocytes. Retinal accelerates surface cell turnover, increasing the rate at which melanin-containing pigmented cells are replaced by new, unpigmented cells. Each addresses a different stage of the melanin cycle — production, distribution, and removal — producing truly non-overlapping, complementary brightening activity.

Q: Can I layer this with the Azelaic Acid 10 Kojic Tea Tree Serum?
A: Apply them on alternating evenings rather than the same evening to avoid over-stimulating the skin. Both are evening actives with acid content; using them together daily can compound the potential for barrier disruption.
