Erborian Bi-Phase Night Oil-Serum 0.3 fl oz — Lightweight, 10% PHA & Hyaluronic Acid for Smoother, Brighter Skin

Erborian Skin Therapy Multi-Perfecting Bi-Phase Night Oil-Serum is a two-phase Korean night serum that blends into a lightweight oil-serum to hydrate, smooth, brighten, and visibly improve skin texture overnight.

This bi-phase formula mixes a nourishing oil layer with a lightweight milky serum to deliver seven targeted skin benefits while you sleep. Formulated with 17 plant extracts plus five potent actives — including 10% PHA and hyaluronic acid — it is designed to absorb quickly without a greasy finish. Shake to combine the layers, apply a few drops as the last step of your evening routine, and let the concentrated ingredients work through the night to help refine texture and even complexion.

How does the bi-phase texture work on different skin types?

The two layers separate to preserve ingredient potency and blend into a silky emulsion when shaken. This creates a light, fast-absorbing finish that gives the nourishment of an oil without heavy residue, making it suitable for normal, combination, and oily skin as well as dry skin that needs targeted care.

• Shake to emulsify oil and serum into a uniform texture.
• Lightweight emulsion absorbs quickly and won’t clog pores.
• Formulated for balancing nourishment and non-greasy feel.

What skin concerns does it target and how quickly will I see results?

Skin Therapy targets seven concerns: texture, fine lines, firmness, luminosity, hydration, complexion evenness, and refinement. Some users notice immediate smoothing or glow after the first night, while measurable improvements in texture and evenness develop with continued use as active ingredients like PHA and hyaluronic acid work over time.

• PHA helps gently exfoliate to improve skin texture and clarity.
• Hyaluronic acid hydrates and plumps surface fine lines.
• Yuzu and red pepper extracts add brightness and luminosity.

Which key ingredients are included and what do they do?

The formula combines 17 plant extracts with targeted actives to deliver multi-action benefits. Notable components include 10% PHA for gentle exfoliation, hyaluronic acid for hydration and plumping, zinc for texture support, plus white and red ginseng to help improve the appearance of fine lines and add resilience.

• 10% PHA: gentle resurfacing and improved texture overnight.
• Hyaluronic acid: surface hydration and temporary plumping effect.
• Yuzu & red pepper extracts: brighten and boost radiance.
• White and red ginseng: traditional botanicals for firmness and vitality.

How should I use this night oil-serum in my routine?

Use Skin Therapy as the final step of your evening skincare routine after cleansing and serums. Shake the bottle, dispense a few drops into palms, warm between hands, and press gently over face and neck to help absorption; no rinsing needed.

• Shake well before each use to combine layers.
• Apply 3–5 drops to face and neck at night as last step.
• Can be layered over lighter serums or used alone on top of moisturizer.
