Collistar Pure Actives Hyaluronic & Polyglutamic Acid Serum 30ml

This 30ml serum delivers sustained surface hydration by combining hyaluronic acid with polyglutamic acid in a single formula, addressing moisture loss across different skin depths.

Hyaluronic acid penetrates quickly to replenish depleted layers, while polyglutamic acid binds substantially more water by weight and creates a flexible film that reduces transepidermal water loss throughout the day. Together, these actives smooth texture and diminish the visual depth of fine lines without adding residue, oil, or a tight feeling after absorption.

Dose three to four drops onto cleansed skin each morning and evening. Pat gently until fully absorbed, then follow with your regular moisturizer and broad-spectrum sunscreen. The fluid consistency integrates cleanly beneath primers, foundations, and makeup sunscreens without pilling or shifting coverage. It functions effectively for normal, dry, combination, and sensitized skin profiles that require reliable moisture management.

Collistar Pure Actives isolates these two hydrating molecules at targeted concentrations, omitting heavier occlusives and fragrance that often interfere with active penetration. The precision-formulated 30ml container maintains ingredient stability across standard storage conditions, providing consistent potency through a full month of routine application.
