SUNGBOON EDITOR - Active Marine Astaxanthin Toning Serum Mask 23ml X 10ea

SUNGBOON EDITOR Active Marine Astaxanthin Toning Serum Mask 23ml x 10 — Korean Brightening Antioxidant Sheet Mask

The Astaxanthin Toning Serum Mask is the sheet-mask treatment of SUNGBOON EDITOR’s Astaxanthin line — a box of 10 masks, each soaked in a brightening, antioxidant serum built around astaxanthin. It delivers the line’s tone-up and glow angle in a relaxing 15-minute step, pairing the marine antioxidant with a PHA, tranexamic acid and glutathione for radiance and smooth texture.

The essence combines antioxidants (astaxanthin, vitamin E, safflower and sea buckthorn oils), brighteners (tranexamic acid, niacinamide, thuja) and a gentle PHA (gluconolactone), buffered with soothing panthenol, allantoin and bisabolol.

What the Toning Serum Mask Does

• Brightens and evens tone. Tranexamic acid, niacinamide and thuja target dullness and uneven tone for a tone-up glow.
• Delivers antioxidants. Astaxanthin, vitamin E and antioxidant plant oils defend against the free-radical damage behind tired skin.
• Smooths texture. A gentle PHA (gluconolactone) refines the surface without stinging.
• Hydrates and soothes. The AQUAXYL moisture complex plus panthenol, allantoin and bisabolol keep skin plump and calm.

Who the Toning Serum Mask Is For

• Skin that looks dull, tired or uneven and wants a brightening boost
• Anyone after a glow before an event or a relaxing weekly treatment
• Those building the Astaxanthin routine who want the matching sheet mask
• Skin that wants gentle PHA smoothing in a low-effort format

Key Ingredients in the Toning Serum Mask

• Astaxanthin + Haematococcus Oil — the marine antioxidant, for glow and protection.
• Tranexamic Acid + Niacinamide + Thuja — the brightening, tone-evening trio. More in our niacinamide guide.
• Glutathione + Vitamin E — antioxidant and radiance support.

• AQUAXYL + Sea Buckthorn & Safflower Oils — hydration and nourishment.
• Panthenol, Allantoin & Bisabolol — soothing and calming.

Texture and Finish

A serum-soaked sheet that clings closely and leaves skin brightened, smooth and dewy after 15–20 minutes. There is a light scent from the anise, and the essence contains some alcohol for a fresh finish.

Why You’ll Love It

• A brightening boost in one step. Astaxanthin, tranexamic acid and niacinamide together.
• Gentle smoothing. A PHA refines texture without irritation.
• Antioxidant glow. Marine astaxanthin plus vitamin E and plant oils.
• Great before an event for an instant tone-up.
• Honest about brightening. It gives an immediate glow, with tone-evening building over regular use — alongside SPF.

How to Use the Toning Serum Mask

1. After cleansing and toner, unfold the mask and lay it evenly over the face.
2. Leave on for 15–20 minutes — no longer, or it starts to dry out.
3. Remove and gently pat the remaining essence into the skin.
4. Follow with moisturizer to seal it in. Use 1–3 times a week, or before an event.
5. Because it contains a PHA, wear sunscreen the next morning.

How to Add It to Your Routine

Use it as a weekly-to-few-times-weekly treatment in place of your serum step: cleanse → tone → mask → moisturizer. It fits alongside the daily Astaxanthin Serum and Capsule Cream.
