What it is

A brightening serum that blends niacinamide with a vitamin-rich complex and hydrating agents to support a more luminous, even-looking complexion while maintaining lightweight moisture.

Who it's for

  • Dull or uneven-looking skin seeking radiance and tone refinement.
  • Normal, combination, or oily skin types preferring a fast-absorbing serum.
  • Routines that layer hydration under sunscreen and makeup without heaviness.

Key ingredients (INCI)

  • Niacinamide — cosmetic brightening, tone-evening, and barrier support.
  • Vitamin complex (e.g., vitamin C derivatives, panthenol) — helps improve radiance and comfort.
  • Humectants (e.g., glycerin, sodium hyaluronate) — attract and hold moisture.
  • Soothing agents (e.g., allantoin/centella derivatives) — buffer potential irritation from actives.

Free-from / texture

  • Lightweight, watery-to-dewy serum; absorbs quickly.
  • Low oil content and low residue; check INCI for fragrance sensitivities.
  • Layers cleanly under moisturizer and sunscreen for day or night use.

How to use & order

  • After cleansing and toner, apply 1–2 pumps over face and neck.
  • Use morning and/or night; follow with moisturizer and daytime sunscreen.
  • Can be paired with hydrating toners/essences for extra moisture before sealing with cream.

Conflicts & layering tips

  • Compatible with most routines; if using strong acids or retinoids, alternate days to reduce sensitivity.
  • Pair with barrier creams to lock in hydration and minimize potential dryness.
  • Patch test if sensitive to niacinamide or vitamin complexes at higher levels.

Evidence & notes

  • Radiance and tone-evening effects are cosmetic; consistent use is needed to maintain appearance.
  • Niacinamide supports a more even-looking tone and barrier resilience with regular use.
  • Humectants draw moisture; sealing with moisturizer reduces transepidermal water loss.

Safety

  • For external use only; discontinue if irritation occurs.
  • Patch test before first use, especially if you have sensitive or reactive skin.
  • Avoid applying on compromised or freshly exfoliated areas; consult a professional if post-procedure.
  • Pregnancy/breastfeeding: cosmetic ingredients; defer to your physician for personal guidance.
