Isa Knox Regenerating
ISA KNOX Regenerating on skinsli covers 34+ products from the brand's Terbina and Tervina regenerating lines. The LX (Luxury) tier introduces premium versions: the Tervina LX Regenerating Cream 60ml (a larger, richer cream format), the Tervina LX Regenerating Essence Cushion 15g (a cushion foundation with regenerating actives), and the dedicated Tervina Advanced Regenerating Serum 20ml. The Tervina Advanced Regenerating Cream 25ml is a smaller cream format within the same Advanced sub-line. Men's coverage comes from the Terbina LX Homme Regenerating Toner 150ml. The regenerating concept runs through every step: the AD Regenerating toner and emulsions from the Terbina line anchor the routine, and the Tervina LX products elevate specific steps to a premium tier.

Buying Guide: ISA KNOX Regenerating Skincare Collection
The ISA KNOX Regenerating collection on skinsli spans 34+ products across the Terbina and Tervina sub-lines, with a particular emphasis on the LX (Luxury) tier products. From the AD Regenerating toner and emulsions to the Tervina LX Cream, Serum, and Essence Cushion, this is the most complete view of ISA KNOX's regenerating product range. This guide explains the LX tier, the serum and cream options, and how to build a regenerating routine from the available products.
The LX tier: what Luxury means in ISA KNOX Regenerating
LX in ISA KNOX's product naming stands for Luxury - a premium sub-tier within the Terbina and Tervina regenerating lines. LX products use higher concentrations of actives and more refined delivery systems than standard Terbina products. The three LX products in this collection are the Tervina LX Regenerating Cream 60ml, the Tervina LX Regenerating Essence Cushion 15g, and the Terbina LX Homme Regenerating Toner 150ml for men. Each is the premium version of its product category within the regenerating range.
For users who want the full regenerating treatment at the highest available intensity, building a routine from LX products where available (LX Cream for the moisture step, LX Homme Toner for the men's first step) delivers the most concentrated regenerating actives. Non-LX products like the AD Regenerating Emulsion and Tervina Advanced Regenerating Serum work effectively at a lower intensity and a lower price point.
Tervina Advanced Regenerating Serum 20ml
The Tervina Advanced Regenerating Serum 20ml is the dedicated serum step in the regenerating routine. Serums in Korean skincare are mid-routine treatments applied after the emulsion and before the cream - they deliver a higher concentration of actives than a toner or emulsion but without the finish-layer function of a cream. At 20ml the Tervina serum is a smaller format, suggesting concentrated delivery where two to three drops is the recommended dose per application.
This serum is distinct from the Terbina AD Prima Elixir in the broader range: the serum format is applied across the full face as a routine step, while an elixir may be used more selectively. For a complete regenerating routine, both can be layered - elixir then serum - or the serum can be used as the single treatment step for a more streamlined approach.
Two regenerating cream sizes: 25ml and 60ml LX
Two cream formats are available in the regenerating collection. The Tervina Advanced Regenerating Cream 25ml is the standard size - a full-face moisturiser for the cream step in the routine. The Tervina LX Regenerating Cream 60ml is the larger LX-tier cream: more product per unit at a higher active concentration. At 60ml the LX Cream is more economical on a per-use basis for regular users, as a 60ml cream at standard application lasts two to three times longer than a 25ml.
For first-time Tervina cream users, the 25ml is the lower-commitment option to test the formula. Once confirmed, the 60ml LX delivers the premium-tier regenerating treatment and better value per gram. The LX Cream is the final sealing step in a full morning or evening routine - apply after the serum with a gentle press-and-smooth motion.
Tervina LX Regenerating Essence Cushion 15g
The Tervina LX Regenerating Essence Cushion 15g is a cushion foundation that incorporates the regenerating essence actives into the cushion formula. Cushion foundations in Korean makeup deliver a combination of skincare and coverage in one application - the cushion pad holds a liquid formula that hydrates while providing sheer to medium buildable coverage. The LX Regenerating Cushion extends the regenerating treatment from the skincare steps into the makeup application, maintaining the repair-and-regenerate philosophy through to the finished look.
At 15g it is a standard Korean cushion size. The cushion is particularly useful for mature skin where a powder-only finish looks flat - the essence in the cushion liquid keeps the skin surface looking hydrated and less settled into lines than a dry powder finish does. Apply after sunscreen with one to two presses per zone.
Terbina LX Homme Regenerating Toner 150ml
The Terbina LX Homme Regenerating Toner 150ml is the premium men's first-step product in the regenerating range. As an LX product, it uses a higher-concentration formula than the standard Terbina men's products. At 150ml it is a generous size for a first-step toner. The toner delivers regenerating actives from the first moment of the routine, priming the skin surface for the emulsion and serum steps that follow.
Men who want the highest-intensity regenerating treatment in their simplified routine can build around this LX Toner and the Tervina LX Regenerating Cream, which creates a two-step LX routine that covers the opening and closing of the routine with premium-tier actives.
Terbina vs Tervina: the naming difference
Some products in this collection are labeled "Terbina" and others "Tervina" - the spelling differs by one letter. This is an ISA KNOX internal naming distinction, not a typo. Both names refer to closely related lines within ISA KNOX's regenerating category. Terbina covers the core AD Regenerating products (toner, emulsion, elixir), while Tervina appears on the Advanced and LX tier products (Advanced Regenerating Serum, LX Cream, LX Cushion). Both are manufactured by ISA KNOX (LG Household and Health Care) and share the regenerating formula philosophy.
Building a complete regenerating routine
A standard-tier regenerating morning routine: Terbina AD Regenerating Softener (toner) → Terbina AD or Advanced Regenerating Emulsion → Tervina Advanced Regenerating Serum → Tervina Advanced Regenerating Cream 25ml → sunscreen → Tervina LX Regenerating Essence Cushion for base coverage. An LX-intensity version replaces the standard cream with the LX Cream 60ml and uses the LX Homme Toner (for men) at the first step.
The regenerating collection on skinsli supports building at multiple intensity levels - from a two-product starter (LX Toner + LX Cream) to a full five-step layered routine. The Terbina Advanced Regenerating set of 2 bundles two products for value entry into the Advanced tier without purchasing each piece separately.

FAQ
Frequently asked questions
What does the ISA KNOX Regenerating collection include?
The collection covers 34+ regenerating skincare products from the Terbina and Tervina sub-lines. Key products include the Terbina AD Regenerating toner and emulsions, the Tervina Advanced Regenerating Serum 20ml, Tervina LX Regenerating Cream 60ml, Tervina Advanced Regenerating Cream 25ml, the Tervina LX Regenerating Essence Cushion 15g, and the Terbina LX Homme Regenerating Toner 150ml for men.
What does LX mean in ISA KNOX product names?
LX stands for Luxury - the premium tier within ISA KNOX's Terbina and Tervina regenerating lines. LX products use higher active concentrations and more advanced delivery systems than standard or Advanced variants. The LX products in this collection are the Tervina LX Regenerating Cream 60ml, the Tervina LX Regenerating Essence Cushion 15g, and the Terbina LX Homme Regenerating Toner 150ml.
Should I buy the Tervina Advanced Regenerating Cream 25ml or the LX Regenerating Cream 60ml?
The 25ml is for testing the formula - it lasts about three to four weeks at once-daily use. The LX 60ml is the better long-term choice: it has a higher concentration (LX tier) and more product per purchase, making it more economical per gram for regular users. If you have not used Tervina Regenerating Cream before, start with the 25ml, then switch to the LX 60ml once you confirm the formula works for your skin.
How much of the Tervina Advanced Regenerating Serum 20ml should I use per application?
Two to three drops is the standard dose for a concentrated regenerating serum. Apply after the emulsion and before the cream, pressing the drops gently into the skin with both palms. At 20ml and two drops twice daily, the bottle lasts approximately two to three months. Use it consistently rather than occasionally for visible regenerating results over six to eight weeks.
Is the Tervina LX Regenerating Essence Cushion 15g suitable for mature skin?
Yes - the essence in the cushion formula keeps the skin surface looking hydrated during wear, which is particularly useful for mature skin where a dry powder finish settles into fine lines. The LX Regenerating actives continue the treatment function of the skincare steps through to the finished makeup application. Apply with two to three presses per zone after sunscreen.
Are Terbina and Tervina the same brand line?
Yes - both are ISA KNOX sub-lines under LG Household and Health Care. The one-letter difference in the name is intentional: Terbina covers the core AD Regenerating products (toner, emulsion, elixir), while Tervina appears on Advanced and LX tier products (Advanced Serum, LX Cream, LX Cushion). Both use the same regenerating philosophy and are manufactured by ISA KNOX.
What makes the Terbina LX Homme Regenerating Toner 150ml different from standard men's toners?
The LX Homme Regenerating Toner is the premium-tier first step for male skin in the ISA KNOX regenerating range. LX indicates higher active concentrations than standard products. At 150ml it is a full-size bottle. For men who want a more intensive regenerating treatment than the standard Terbina Homme products, the LX Toner delivers the highest available concentration from the opening step of the routine.
What is the simplest ISA KNOX Regenerating routine I can build?
A minimal two-step routine: Terbina LX Homme Regenerating Toner 150ml (men) or Terbina AD Regenerating Softener (standard) → Tervina LX Regenerating Cream 60ml. This covers the opening prep step and the closing moisture-barrier step with LX-tier actives at both ends. For a three-step version, add the Tervina Advanced Regenerating Serum between the toner and cream.
Is the ISA KNOX Regenerating collection different from the Age Focus collection?
Yes - the Regenerating collection focuses specifically on cell regeneration and skin repair through the Terbina and Tervina lines. The Age Focus collection focuses on wrinkle reduction and collagen support through the Age Focus Prime and Vital Collagen sub-lines. Both are anti-aging, but from different angles: Age Focus targets visible lines and firmness, while Regenerating targets skin surface renewal and repair. Some products appear in both grids if they carry both "Age" and "Regenerating" in their names.
Are ISA KNOX Regenerating products on skinsli authentic?
Yes. ISA KNOX is a South Korean brand under LG Household and Health Care. All regenerating products on skinsli are sourced from authorised channels, manufactured in South Korea, and include Korean and English labelling with expiry dates.
