Erborian Skin Therapy Multi‑Perfecting Bi‑Phase Night Oil‑Serum 1 oz — 10% PHA & Hyaluronic for Smoother, More Radiant Skin

Erborian Skin Therapy Multi-Perfecting Bi-Phase Night Oil-Serum is a two-phase nighttime oil-serum that blends on shake to deliver seven visible skin benefits overnight without a greasy finish.

This hybrid Korean night treatment combines a lightweight oil layer with a milky serum to target texture, tone, hydration and signs of aging using 17 plant extracts plus clinically familiar actives like 10% PHA and hyaluronic acid. Designed to absorb quickly, the formula balances nutrient-rich oils with exfoliating and hydrating ingredients so skin looks smoother, plumper and more even after the first night while building longer-term improvements with continued use.

How does this two-phase oil-serum work for different skin types?

The bottle holds two distinct layers: an oil phase for nourishment and a serum phase for delivering water-soluble actives. When shaken, the layers emulsify into a featherlight texture that sinks in fast, making it suitable for normal, combination and oily skin as well as drier skin needing overnight repair.

• Shake to mix the oil and serum into a uniform texture.
• Lightweight finish minimizes greasy residue and pore clogging.
• Formulated for quick absorption on combination or oily skin.
• Also provides overnight nourishment for drier skin types.

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

The formula targets seven visible concerns: uneven tone, dullness, fine lines, texture, hydration, firmness and overall radiance. Immediate benefits like enhanced luminosity, improved softness and smoother texture can be noticeable after one night; sustained improvement in lines and tone builds with regular use.

• 10% PHA plus zinc help refine surface texture and gentle exfoliation.
• Hyaluronic acid plumps and hydrates for immediate smoothness.
• Yuzu and red pepper extracts boost brightness and glow.
• White and red ginseng support the appearance of firmness over time.

What are the key ingredients and what does each one do?

The serum blends 17 botanical extracts with five standout actives chosen for complementary benefits. Each component plays a role—from gentle chemical exfoliation to hydration and nutrient-rich oils that reinforce the skin barrier overnight.

• PHA (10%): gentle exfoliation to improve texture and clarity.
• Hyaluronic acid: immediate hydration and plumping effect.
• Yuzu extract: helps even complexion and brighten dull skin.
• Red Pepper extract: adds instant luminosity and vitality.
• White & red ginseng: visible support for fine lines and resilience.

How should I include this in my nighttime routine?

Use Skin Therapy as the final step of your evening regimen after cleansing and any water-based serums. Shake the bottle, dispense a few drops, warm between palms and press gently into face and neck; a little goes a long way and the lightweight finish means you can layer it under sleeping masks if desired.

• Apply 2–4 drops after toner and serums, before any heavier creams.
• Warm between palms to emulsify and promote absorption.
• Safe to combine with most actives; patch test if using potent treatments.
• Use nightly for best cumulative results.

Who is this for: Erborian Skin Therapy is designed for anyone seeking a multitasking nighttime treatment that provides both immediate skin-smoothing and longer-term improvements. It suits people who want a nourishing but non-greasy oil-serum, those with uneven tone or texture, and users looking to add hydration and visible plumping to their sleep-time routine. The formula avoids sulfates, parabens, phthalates and other listed nasties and is not tested on animals, making it a solid option for shoppers focused on efficacious, modern K‑beauty hybrids.
