Description

Elixir The Serum aa is a high-performance medicated beauty serum engineered to address multiple signs of aging skin in a single application. Formulated with 21 beauty ingredients and a proprietary delivery technology, it reaches deep into the stratum corneum rapidly, making it noticeably effective even on days when a full multi-step routine is not possible. It carries the Japan-domestic quasi-drug designation, meaning its active ingredients have passed efficacy testing under Japanese pharmaceutical standards.

Coreximide (hydroxyethylethyleneurea) is the hero ingredient — a Shiseido-developed compound that targets the skin's basement membrane, the structural layer underlying the epidermis, to help restore the skin's underlying firmness and density over time. Tranexamic acid, the medicated whitening active, works simultaneously to suppress melanin formation and reduce the appearance of dark spots. The result is skin that improves in firmness, brightness, and smoothness together.

Housed in a glass dispenser bottle. Texture is a clear, slightly viscous gel-liquid with a relaxed aquatic floral scent. Apply after toner, morning and night.

Key Ingredients
  • Coreximide (Hydroxyethylethyleneurea) — Shiseido's proprietary active that works at the basement membrane level to help restore the skin's foundational firmness and density
  • Tranexamic Acid (Medicated Active) — suppresses melanin generation at the source, reducing dark spots and improving overall clarity over time
  • High-Concentration Water-Soluble Collagen — delivers a cushioned, plump skin feel and supports visible reduction in fine surface lines
  • Watercress Extract — a select botanical that contributes to skin conditioning and overall tone clarity
  • Glycerin Complex — multi-functional humectant base that aids rapid absorption of the full ingredient payload

HOW TO USE
  1. After applying toner, dispense two pumps into the palm.
  2. Spread across the face starting from the cheeks, working upward toward the eyes and forehead.
  3. Use morning and night before emulsion or cream.
  4. Follow with emulsion and, if desired, Elixir Advanced Emulsion or a night cream for additional moisture.
  5. Pro tip: When using in the morning, always follow with SPF — tranexamic acid efficacy is best preserved when UV exposure is controlled.

FAQ

What makes this a medicated (quasi-drug) serum?

In Japan, quasi-drug (医薬部外品) status means the product contains active ingredients — here tranexamic acid for whitening — that have undergone regulated efficacy testing. This is a higher standard than standard cosmetics and gives greater confidence in the whitening and wrinkle-related claims.

How does Coreximide work?

Coreximide is a compound developed through Shiseido's research into the skin's basement membrane — the structural layer between the epidermis and dermis. By supporting this layer, the ingredient helps skin recover its ability to hold its own shape and firmness over time, rather than addressing only surface texture.

Can I use this with retinol products?

Yes, this serum can be layered in the same routine as retinol. Apply this serum first after toner, then follow with retinol-based treatment if using one. Both morning and evening use is supported.

Is this the Japan-domestic version?

Yes. TokyoShelf sources directly from Matsumotokiyoshi and authorised Japanese drugstores. This is the Japan-domestic formula carrying the quasi-drug designation — the same version sold at pharmacies across Japan.
