isoi Ampoules

The ISOI ampoule range covers three format types. Liquid serums (Moisture Doctor Ampoule 40ml, Chicago Sika Double Effect Ampoule 30ml, Intensive Elastic Ampoule 30ml, Ultra Water Pool Ampoule 15ml) are the most standard format - applied in drops after toner. Cream-ampoule hybrids (Compression Cream Ampoule 70ml, Moisture Doctor Speedy Cream Ampoule 40ml, Moisture ZIP Cream Ampoule 70ml) combine ampoule-level actives with a cream texture, functioning as a moisture step with concentrated treatment properties. The Intensive Lifting Ampoule Stick 15ml is an ergonomic stick applicator for targeted contour application.

The format differences affect where in the routine each product sits. Liquid ampoules apply at the serum step; cream ampoules can replace or supplement the moisturiser step.

Two Moisture Doctor ampoules appear in the collection. The Moisture Doctor Ampoule 40ml (also listed as Moisture Doctor Ampoule Moisture Ampoule 40ml - the same product) is a liquid serum applying at the treatment step after the Moisture Doctor Toner. At 40ml it is larger than most ampoules, reflecting its role as a daily step rather than a short-course intensive. The Moisture Doctor Speedy Cream Ampoule 40ml is the cream-ampoule variant, absorbing quickly and providing both treatment and moisture in one layer.

Choose the standard Ampoule 40ml for dry skin needing a dedicated serum layer before a separate moisturiser. Choose the Speedy Cream Ampoule for oily or combination skin where a combined serum-plus-light-moisture step reduces the total number of layers without sacrificing the Moisture Doctor actives.

The Compression Cream Ampoule 70ml is the largest product in the collection - a cream-ampoule format combining treatment-level active concentration with a full daily moisturiser size. The Compression designation suggests a formula that helps the skin maintain its structure and moisture retention through a tightening or barrier-compression approach. At 70ml it is generous for daily use, covering approximately two to three months as a routine moisturiser.

This product suits skin that needs both treatment and solid daily moisture in one step, eliminating the need for a separate serum and cream when the concentrated cream format provides both. It is heavier than the Speedy Cream Ampoule and more appropriate for dry or mature skin than for oily skin types.

The Ultra Water Pool Ampoule 15ml and its Bulgarian Rose variant (Bulgarian Rose Ultra Water Pool Ampoule 15ml) are compact 15ml ampoules providing intensive hydration in a water-type formula. The Water Pool designation suggests a formula with a high water-binding capacity, delivering a burst of hydration at the serum step. The Bulgarian Rose version adds rose extract's calming and antioxidant properties to the same hydration base.

At 15ml both are small ampoules suited for trial, travel, or as a supplementary booster layered before a primary serum. They are not primary daily treatment products at this size - they provide an additional hydration layer within a broader routine rather than serving as the main serum step.

The Intensive Lifting Ampoule Stick 15ml is the most distinctively formatted product in the collection. The stick applicator - either a rollerball or pointed tip - delivers lifting ampoule actives precisely along contour areas: jawline, cheekbones, and the outer eye area. This format applies the product with a massaging motion that complements the lifting intent of the formula, since the mechanical stimulation from rolling also improves circulation and product absorption.

Use the Ampoule Stick at the serum step, tracing it along contour areas before the face cream. It works well as a secondary step alongside the standard Intensive Lifting Serum from the ISOI Intensive range, or as a standalone lifting treatment in a minimal routine that doesn't need a full-face serum.

The Chicago Sika Double Effect Ampoule 30ml is from the ISOI Chicago sub-line with a sika (deer) placenta or sika-named complex as a key active. Double Effect products in Korean skincare typically combine two complementary functions in one formula - in this case, likely brightening and hydration or anti-aging and moisture. At 30ml it is a standard ampoule size for approximately three to four weeks of daily use as the serum step.

The Chicago Sika Ampoule is positioned as a multi-function treatment targeting two concerns simultaneously. It is suited to skin that needs more than one type of active at the serum step without wanting to apply two separate serums.

The Intensive Perfect Anti-aging Program Elastic Ampoule 30ml belongs to the Intensive range and sits at the concentrated end of ISOI's anti-aging treatment options. The Elastic designation indicates a formula focused on skin elasticity - improving the skin's ability to spring back and resist the sagging associated with collagen and elastin decline. At 30ml it is a standard serum size for three to four weeks of daily use.

This ampoule pairs naturally with the Intensive Lifting Serum and Ampoule Stick from the broader Intensive collection - all three address different aspects of skin firmness and elasticity. Use the Elastic Ampoule at the main serum step and the Lifting Ampoule Stick as a targeted contour application at the same routine position or after the serum is absorbed.
