How it works
NINELESS B-Boost 1% Kojic Acid Toner is a toner sold in NINELESS's Korean-market packaging and format. Niacinamide is listed 5th of 21 ingredients, an early, prominent position on the list, carrying this formula's brightening and tone-evening work. Kojic Acid is listed 6th of 21 ingredients, an early, prominent position on the list, carrying this formula's brightening and tone-evening work. Adenosine is listed 11th of 21 ingredients, a supporting position further down the list, adding the conditioning, moisture-supporting quality this formula relies on. Sodium Hyaluronate and Dipotassium Glycyrrhizate are also present on the list, in a supporting amount alongside the ingredients above. It takes the step right after cleansing of a Korean-style layering routine, used after cleansing, am and/or pm.
Key benefits
- Niacinamide sits early in the 21-ingredient list, a tone-evening ingredient that works on visible unevenness and surface texture
- Kojic Acid sits early in the 21-ingredient list, a brightening acid derived from fermentation, used in this formula for an evener finish
- Adenosine sits mid-way through the 21-ingredient list, a smoothing ingredient long used in Korean formulas to soften the look of fine lines
- Sodium Hyaluronate sits in the back third of the 21-ingredient list, a salt form of hyaluronic acid that draws and holds water at the skin's surface
- Formulated as a toner from NINELESS, sized for regular use in a routine
- Comes in a 200ml format, sized for the toning step right after cleansing

Is this the authentic Korean-market version, not a US retail reformulation?

How to use
- Use the B-Boost 1% Kojic Acid Toner straight after cleansing, morning and evening, while the face is still damp.
- Apply a moderate amount to the face using a cotton pad or your hands.
- It goes on before serum and moisturizer, and the damp layer it leaves is what the step above it holds on to.
- Twice a day, every day. Do not let it dry down completely before the next layer goes on, or you lose the reason for applying it to damp skin.
Worth knowing
- Patch test on the inner arm 24 hours before adding this to your face or scalp, as with any new product.
- Introduce it gradually alongside the rest of your routine rather than adding several new actives at once.
