Letizia Calming Cell Deep Bio + EGF Brightening Serum Duo 50ml x2

Firmer, brighter skin without the guesswork

Letizia's Calming Cell Deep Bio + EGF Serum Duo pairs two 50ml bottles of a concentrated brightening formula built around EGF (epidermal growth factor) and deep bio-fermented extracts. Korean skincare routines lean on layering actives that calm first and brighten second — this duo gives you a full course to work through morning and night without running out halfway.

Is this serum suitable for sensitive skin?

Yes, the calming cell formula is designed for all skin types, including sensitive skin. As with any new product, we recommend a patch test 24 hours before regular use.

How long will one bottle last?

With twice-daily use, a 50ml bottle typically lasts 6-8 weeks, so the duo covers roughly three to four months of use.

Can I use this with other actives like retinol or vitamin C?

Yes, it layers well with most routines. Introduce one new active at a time and space out strong exfoliants or retinol to avoid irritation.

Where is this shipped from and how long does delivery take?

Orders ship from our Australian-bound partner warehouse and typically arrive within 7-14 business days. You'll receive a tracking link as soon as your order is dispatched.

Every bottle is part of a two-pack set, so you always have a backup on hand instead of reordering mid-routine. Store in a cool, dry place away from direct sunlight to preserve the formula between uses.
