Astrid Bioretinol Serum 30ml

Astrid Bioretinol Serum 30ml contains exactly 30 milliliters of active facial treatment, formatted for direct application into structured skincare cycles. This serum concentration delivers a controlled dosage per use, supporting consistent evening routines designed around progressive skin management.

The fluid consistency spreads uniformly after cleansing, allowing each measured application to interact with prepared skin before heavier hydrators are introduced. The reservoir holds enough product to sustain a standard treatment period, reducing mid-cycle interruptions and ensuring continuous exposure to the active formula.

Usage and Sequencing

• Apply after cleanser and toner, before moisturizers or occlusive layers
• Dispense two to four drops evenly across the face and cervical area
• Press gently to distribute; leave on for uninterrupted overnight absorption
• Store vertically at stable room temperature to prevent separation or leakage

Because bioretinol derivatives perform optimally under consistent scheduling, this 30ml volume removes forecasting uncertainty from your restocking process. The contained design maintains formulation integrity between applications and fits standard travel protocols without compromising dose precision. Pair with morning UV protection to stabilize treated regions after waking.
