The most concentrated press-and-mix format in Numbuzin's No. 5 line. Pure glutathione is kept in powder form, separate from the serum, until it's time to mix — the only way to preserve its true activity without compromising stabilizers.

The result combines pure glutathione with tranexamic acid and niacinamide in a two-week cycle for active blemishes or uneven tone that doesn't respond to maintenance treatments. Unlike the daily-use No. 5+ serum (BYNUT_0241), this is a targeted intervention, not a routine.

Curated for all skin types during the two-week cycle.

When: Morning and/or night. Two-week cycle.

Routine step: After cleansing and toning, before moisturizing. Mix the powder with the serum before first use—this activates the pure glutathione.

Frequency: Use the entire ampoule within two weeks of opening. This is not a serum for indefinite use.

Warnings:
• Daily SPF use is essential to protect the results of the dark spot treatment.
• Once mixed, store in a cool place and use within 14 days.

Numbuzin's No. 5 Glutathione TXA Advanced Dark Spot Ampoule Concentrate is an intensive cycle press-and-mix ampoule: pure glutathione is preserved as a powder in the upper chamber, separate from the tranexamic acid and niacinamide serum, until it's time to mix. The reason is chemical — pure glutathione oxidizes on contact with water and loses its activity. The press-and-mix format activates it at the time of use and guarantees the active ingredient's true potency.

For all skin types with active dark spots or uneven tone that does not respond to maintenance treatments.

Key Ingredients:
• Pure glutathione: antioxidant that directly inhibits melanin synthesis — the most concentrated form possible in a cosmetic product
• Tranexamic acid: precision active for post-inflammatory and hormonal dark spots with high tolerability
• Niacinamide: inhibits melanin transfer and progressively evens out skin tone

The first changes in tone are visible after 6-8 weeks of continuous use.
