KOCOSTAR to Launch Next-Generation Olive Skincare "&Olive" on October 1

KOCOSTAR launches "&Olive," a new series focused on fermented olive

Korean cosmetics brand KOCOSTAR will launch "&Olive," a next-generation olive skincare line, on Thursday, October 1, 2026. The brand has so far offered part-care items such as sheet masks, but this fall it adds a new series of pore-care serums using its own fermentation technology.

At launch, it is scheduled to go on sale at Ains & Tulpe. Sales at other stores are also planned in stages.

3 intensive-care serums to choose from according to your skin concerns

The "&Olive Fresh Serum" being released this time comes in 3 types containing an ingredient made by fermenting Spanish olives with the brand's own method. The features of each are as follows.

  • PDRN (moisture and skin texture care)
    Contains fermented olive extract and PDRN. It moisturizes pores that stand out when skin is dry and refines skin texture, leading to smooth, glowing skin. Morning use is recommended.

  • PEPTIDE (firmness and skin texture care)
    Contains fermented olive extract and peptides. It is designed to moisturize skin that lacks firmness and aims for a bouncy-looking skin impression. It can be used morning and night.

  • HPR (smoothness and skin texture care)
    Contains fermented olive oil and HPR. It addresses pore concerns caused by uneven skin texture and leaves skin looking smooth. Night use is recommended, and if used in the morning, sunscreen must be used together.
