Torriden in Australia: The DIVE-IN Serum Story, Five Types of Hyaluronic Acid and Where to Start

Hyaluronic acid is not a new idea. By the time Torriden arrived, it was already in nearly every serum on the shelf. So the brand did something quietly clever. It did not claim to have invented the ingredient. It asked a better question: what if you used five different sizes of it, so that moisture could be held at every level of the skin? The answer was a water-thin serum that spent years at the top of Korea's rankings.

The idea behind DIVE-IN

According to brand and reviewer descriptions, DIVE-IN is the flagship line, engineered around a complex of five molecular weights of hyaluronic acid. The explanation is straightforward. Larger molecules sit on the surface and hold moisture there. Mid-range molecules plump the upper layers. Smaller ones move deeper. Reviewers note that the idea of multi-weight hyaluronic acid is well established and that Torriden was not the first to do it, but that it was one of the first to make it accessible at an affordable price. That, as one reviewer put it, is the real innovation.

What the reviewers say

The praise is consistent across Korean and international coverage. The serum is described as lightweight, water-thin and fragrance-free, fast to absorb, and genuinely comfortable for sensitive and combination skin. One Korean review described it as holding the top spot on a major Korean skincare ranking app, and an Australian retailer's editorial called it Korea's favourite serum for over seven years. A common practical note: for very dry skin, pair it with a cream to seal in the moisture. One reviewer said they reach for the cream more often than the serum.

The serum

The Torriden DIVE IN Serum ($24.50) goes on after toner and before moisturiser. Use a few drops, press it in and follow with a cream.

The rest of DIVE-IN

The Torriden DIVE IN Toner ($29.99) is a hydrating prep. The Torriden DIVE IN Soothing Cream ($35.00) is the light gel-cream finish. The Torriden DIVE IN Multi Pad ($28.99) is a swipe-on step. For cleansing, the DIVE IN Cleansing Oil ($29.99) and the DIVE IN Cleansing Foam ($19.99) make a double cleanse.

Barrier and brightening lines

The brand's ceramide direction is in the Torriden SOLID-IN Essence ($28.00) and the Torriden SOLID-IN Ceramide Cream ($32.00). For a brightening-feel step, there is the CELLMAZING Brightening Ampoule ($32.00) and the CELLMAZING Brightening Mask ($49.99).
