OSAJI Enrich Bio Serum 10mL | Japanese Trial-Size Pre-Serum

Selected in Tokyo. Shipped directly from Japan.

OSAJI Enrich Bio Serum is a Japanese pre-serum used right after cleansing, before the rest of your skincare routine. This 10mL trial size is a gentle way to try OSAJI's Enrich Bio series, especially if you like skincare that feels refined, calm, and easy to bring into a daily ritual.

I picked this because it feels like a small, thoughtful introduction to OSAJI: simple packaging, a soft floral scent, and a first-step serum that makes the routine feel a little more considered without becoming complicated.

Why we like it

• Pre-serum step for use immediately after washing the face
• Designed to support a comfortable moisture balance
• Contains chlorella extract and alpha-glucan oligosaccharide as moisturizing ingredients
• Includes mineral-related ingredients and skin-conditioning components for a hydrated feel
• Elegant geranium and Damask rose scent
• 10mL trial size, good for first-time use, travel, or a small gift

How to use

After cleansing, apply to bare skin with the dropper and gently smooth over the face. Follow with your usual lotion, emulsion, cream, or other skincare steps.
