Three freshly activated ampoules for visibly clearer, more even-looking skin
Reach for this concentrated Korean treatment when dark spots, post-blemish marks, sun unevenness or dullness are stealing your glow. Every box gives you three 11ml Double Shot Ampoules—33ml in total—with two formula agents activated just before application.
22,000ppm idebenone, niacinamide, glutathione, adenosine and moisture-supporting ingredients work together to brighten uneven-looking tone, revive dull skin and support a smoother, firmer-looking finish.

Start now—before uneven pigment looks more stubborn
Dark spots build when excess pigment becomes concentrated after sun exposure, blemishes or repeated irritation. More UV exposure can make existing discoloration look deeper and encourage new uneven areas, so waiting can mean a longer correction journey.
The Double Shot works on the visible signs from several angles: niacinamide helps reduce visible pigment transfer; idebenone and glutathione provide antioxidant support; and moisture-replenishing ingredients smooth the skin surface so radiance looks clearer. Use it consistently and protect your progress with sunscreen every morning.

HYDRATEReplenish tired, dry-feeling skin
Glycerin, panthenol, squalane and collagen help support moisture and comfort.

REFRESHLayer without a heavy finish
The light ampoule texture absorbs comfortably without a sticky or greasy after-feel.

Activate both agents for focused dark-spot care
Mix once, then deliver your brightest Double Shot
Align the pump and press once to combine both agents into one freshly activated ampoule. The liposome system helps keep the 22,000ppm idebenone well dispersed for smooth, even application—giving dull, uneven-looking skin concentrated antioxidant and brightening care in every 2–3-drop use.
Why it matters: the two-agent format keeps the formula separated until you activate it, so you get the complete Double Shot exactly when you are ready to begin your routine.


See brighter, clearer and more even-looking skin
See what consistent use can do: the two-week customer comparisons below show brighter clarity, a fresher-looking complexion and a more even visible tone. Make the Double Shot your daily treatment, protect your progress with sunscreen and give your skin the consistency it needs to show change.

Antioxidant, brightening and moisture-supporting care


Mix the two agents, then apply 2–3 drops
Take off the safety lock from the ampoule pump.
Turn the pump until the droplet mark aligns with point 2, then press once to mix agents 1 and 2.
Remove the safety pin at the opening and dispense about 2–3 drops.
Apply evenly over the face and tap gently until absorbed, then follow with moisturiser.
Keep the activated container upright with the dispensing end facing down.
Use sunscreen as the final step of your morning routine. Avoid direct contact with the eyes and stop use if irritation occurs.

Choose it when dark spots and uneven tone are stealing your glow
- Dark spots, post-blemish marks and sun unevenness that need focused daily care.
- Dull-looking skin that needs brighter, clearer-looking radiance.
- Visible fine lines or skin that looks less firm and elastic.
- Dry or tired-feeling skin that benefits from concentrated nourishment.
- Anyone who prefers a light, refreshing ampoule rather than a heavy serum.
