Erborian Skin Therapy Multi-Perfecting Bi-Phase Night Oil-Serum, 0.33 fl oz — 10% PHA, Hyaluronic Acid for Texture & Radiance

Erborian Skin Therapy Multi-Perfecting Bi-Phase Night Oil-Serum is a two-phase Korean night serum that blends into a lightweight, non-greasy emulsion to target seven signs of skin aging and unevenness while you sleep.

Formulated with 17 plant extracts plus five powerhouse actives including 10% PHA and hyaluronic acid, this compact 0.3 fl oz bottle is designed to be shaken into a single, fast-absorbing texture that nourishes without leaving an oily film. The formula combines gentle exfoliation, hydration, and botanical brighteners to improve skin texture, luminosity, and the look of fine lines from the first night, while supporting longer-term complexion refinement with regular use.

How does the bi-phase formula work for different skin types?

When shaken, the oil and milky serum layers emulsify into a thin, easily absorbed finish that balances nourishing lipids with lightweight hydration. That hybrid texture is crafted to suit a wide range of skin types — even combination and oilier complexions can enjoy the benefits without feeling weighed down or shiny.

• Shake to blend oil and serum layers into a milky emulsion.
• Fast absorption leaves minimal surface oiliness.
• Suitable for combination, normal, and oil-prone skin when used sparingly.
• 0.33 fl oz travel-friendly size for trial or travel.

What active ingredients deliver the seven skin benefits?

The formula combines 10% PHA for gentle exfoliation and zinc for texture improvement, plus yuzu and red pepper extracts to brighten and add radiance. Hyaluronic acid and lightweight emollients provide plumping hydration while ginseng extracts support the appearance of firmness and fine line smoothing.

• 10% PHA: softens surface texture and supports cell turnover.
• Hyaluronic acid: hydrates and plumps the look of skin.
• Yuzu and red pepper extracts: boost radiance and even tone.
• White & red ginseng root: help refine the look of fine lines.

When and how should I apply this night oil-serum for best results?

Use the product as the final step of your evening routine on cleansed skin; shake well to combine the two phases, dispense a few drops into the palm, warm between fingers, and press gently into face and neck. Start with a small amount and increase slightly if needed—this helps you control finish and avoid excess oil.

• Apply at night after cleansing and toning, before or in place of a heavier night cream.
• Warm 2–4 drops between palms and press into skin for even absorption.
• Adjust quantity based on skin type: less for oil-prone, a bit more for dry areas.
• Consistent nightly use yields the most noticeable texture and tone improvements.

Is the formula clean and cruelty-free?

Erborian formulates this serum without common problematic ingredients and does not test on animals. The ingredient list avoids sulfates, parabens, phthalates, oxybenzone and other specified nasties, reflecting a skin-centric approach to clean beauty.

• Not tested on animals; formulated for efficacy and tolerability.
• Free from sulfates, parabens, phthalates and oxybenzone.
• Designed to pair with other Korean skincare steps for layered benefits.

Who is this for: Erborian Skin Therapy Multi-Perfecting Bi-Phase Night Oil-Serum is ideal for anyone seeking a compact, multitasking overnight treatment that refines texture, brightens complexion, and hydrates without heavy residue. It suits users wanting both immediate glow and progressive improvement in fine lines, texture, and evenness—especially helpful for travelers, skincare experimenters, and those new to hybrid oil-serums.
