High-level description: A multi-peptide toner–serum hybrid that boosts radiance, improves elasticity, and smooths texture for visibly firmer, more refined skin.

Category: Essence

A lightweight booster formulated with six peptides, niacinamide, and hyaluronic acid to target early signs of aging and dullness.

Acting as a first essence or pre-serum step, it absorbs quickly to revive tired skin, visibly firming and smoothing fine lines while helping minimize the look of pores.

The formula is fragrance-free and alcohol-free, making it gentle yet highly effective.

Boosts radiance and firmness in one light layer.
Refines pores and improves texture for a smoother finish.
Enhances absorption of subsequent serums and ampoules.
Hydrates deeply without stickiness or heaviness.
Curated pick: A true glow booster that softens fine lines, tightens pores, and brightens tone — a daily essential for firm, clear, and balanced skin.

6 Peptide Complex (Acetyl Hexapeptide-8, Copper Tripeptide-1, Oligopeptide-68, Palmitoyl Tripeptide-8, and others) – Signals skin to produce collagen and elastin, helping reduce the look of fine lines and improve firmness.
Hydrolyzed Collagen – Adds moisture and bounce to the skin’s surface, enhancing smoothness and suppleness.
Niacinamide (Vitamin B3) – Brightens tone, supports the barrier, and visibly refines enlarged pores.
Hyaluronic Acid & Panthenol – Deeply hydrate to keep skin plump and comfortable.
Allantoin & Acetyl Glucosamine – Calm irritation and improve overall texture for a soft, even finish.

Apply after cleansing (before or after toner, depending on routine).
Dispense 1–2 pumps and smooth evenly over face and neck.
Allow 20–30 seconds for absorption before applying serum or moisturiser.
Use morning and night for best results.
Tip: Layer twice on areas with visible pores or fine lines for enhanced results.

Step 1: Oil Cleanser → Step 2: Water-Based Cleanser → Step 3: Exfoliator → Step 4: Toner → Step 5: Essence (This Product) → Step 6: Serum / Ampoule → Step 7: Face Mask → Step 8: Eye Care → Step 9: Moisturiser → Step 10: Suncream

Skin Types: Normal, Dry, Combination, Oily, Sensitive

Concerns: Fine Lines, Dullness, Uneven Tone, Enlarged Pores, Loss of Firmness, Dehydration

Pairs well with: Niacinamide, PDRN, and Panthenol — these enhance the peptide blend’s firming and repairing benefits while maintaining hydration and balance.

Compatible with: Almost all skincare actives, including Retinoids, Vitamin C derivatives, Centella Asiatica, Hyaluronic Acid, and Snail Mucin. Peptides are highly stable and can be layered under or over most serums without conflict. They reinforce the skin barrier and boost the results of stronger actives.

Avoid using with: No major incompatibilities. If using immediately after low-pH exfoliants (AHA/BHA/PHA), let skin rest a few minutes before applying to avoid temporary tingling — not due to chemical instability, but to give the skin’s surface pH time to normalise.

Layering tip: Apply after toner as your first serum or essence step. It absorbs quickly and can be followed with up to two or three serums, including Retinoid treatments. Allow each layer to absorb briefly for best results.

Pro Tip: Use consistently with hydrating and barrier-focused products like PDRN, Ceramides, or Snail Mucin for enhanced firmness, elasticity, and post-treatment recovery. Peptides are universally compatible and ideal for building resilience into any active routine.
