PLDQ buying guide: Aquaporin hydration and Expert Protection
PLDQ is a Korean skincare brand organised around two clear lines. The Aquaporin range targets hydration with a water cream, a concentrate ampoule and toning water, while the Expert Protection range covers daily care with toners and lotions, including dedicated men's versions. A raspberry lip sleeping mask rounds out the 36+ products we stock. This guide explains the lines, how to layer them, and how to pick the right item for your skin.
What PLDQ is and who it suits
PLDQ is a Korean skincare house that keeps its catalogue easy to read by grouping products into two named lines. The Aquaporin line leans on water-based hydration, and the Expert Protection line handles everyday toner-and-lotion care. The titles tell you which line a product belongs to, so you can shop by goal instead of guessing.
It suits anyone building a layered Korean routine who wants hydration and daily protection from one brand. Because the Expert Protection line also has men's versions, it works for shared bathrooms where two people want the same approach in formats that suit each of them.
The Aquaporin hydration line
The Aquaporin line is PLDQ's hydration core. It includes the Aquaporin Water Cream 50g, the Aquaporin Concentrate Ampoule 40ml and the Aquaporin Toning Water 125ml. The naming points at water channels in the skin, and the products are built to add and hold moisture across the routine.
The toning water is a first hydrating step after cleansing, the ampoule is a concentrated treatment layer, and the water cream seals everything with a lighter finish than a heavy cream. Used together they give you a full hydration sequence without leaving skin feeling weighed down.
The Expert Protection line
The Expert Protection line covers daily care with larger everyday sizes. It includes the Expert Protection Toner 200ml and the Expert Protection Lotion 200ml, plus the Expert Protection Men Lotion 200ml and men's set options for a simple two-step routine.
The 200ml sizes signal that these are meant for regular, generous use rather than occasional treatment. A toner-then-lotion pairing is the backbone of a basic Korean routine, and this line gives you a matched set to do exactly that for the whole face.
Lip care: the sleeping mask
Outside the two main lines, PLDQ carries the Lip Sleeping Mask Raspberry 20g. A lip sleeping mask is an overnight treatment: apply a layer before bed and let it work while you sleep so lips feel softer by morning.
The 20g size lasts a long time because each use is a thin layer. It slots onto the end of an evening routine, so you can pair it with the Aquaporin water cream and finish the night with both face and lips treated.
How to layer PLDQ products
The two lines layer in a logical order. Start with a hydrating water step such as the Aquaporin Toning Water or the Expert Protection Toner, then add the Aquaporin Concentrate Ampoule as a treatment, and seal with the Aquaporin Water Cream or an Expert Protection Lotion.
The rule of thumb is thin to thick: watery textures first, creams last. If you use both lines, treat the Expert Protection toner and lotion as your daily base and bring in the Aquaporin ampoule when skin needs an extra moisture boost.
Skin-type and concern fit
The hydration focus of the Aquaporin line makes it a strong pick for dry or dehydrated skin that needs more moisture without heaviness. The lighter water cream finish also works for combination skin that wants hydration without a greasy feel.
The Expert Protection line is a steady daily base for most skin types thanks to its simple toner-and-lotion structure. If you are not sure where to begin, the Expert Protection toner and lotion give you a reliable routine, and you can layer in Aquaporin products as your skin tells you it needs more.
Sizes and value
PLDQ sizes its products to how they are used. The Expert Protection toner and lotion are 200ml for daily, generous application, while the Aquaporin ampoule is a smaller 40ml because you use less of a concentrate per application. The water cream is 50g and the toning water is 125ml.
The Expert Protection men's sets are a practical way to start a two-step routine in one purchase. If you want to try the brand first, a single item like the toning water or the lip sleeping mask is a low-commitment way in before you build out a full routine.
Building a routine from PLDQ
Because PLDQ covers cleansing follow-up, treatment and sealing across its lines, you can assemble a coherent routine from one brand. A simple version is the Expert Protection Toner, then the Expert Protection Lotion, finishing with the Lip Sleeping Mask at night.
A more hydration-focused version uses the Aquaporin Toning Water, the Aquaporin Concentrate Ampoule and the Aquaporin Water Cream in that order. Build it up one product at a time so you can judge how your skin responds before adding the next layer.

The Expert Protection line is the daily base, with a 200ml toner and lotion, including men's versions, for regular generous use. Many people use both: Expert Protection as the everyday base and Aquaporin for an extra moisture boost.
In what order should I layer PLDQ products?
Go thin to thick. Start with a watery step like the Aquaporin Toning Water or the Expert Protection Toner, add the Aquaporin Concentrate Ampoule as a treatment, then seal with the Aquaporin Water Cream or an Expert Protection Lotion. Finish an evening routine with the Lip Sleeping Mask.
Which PLDQ line suits my skin type?
The Aquaporin line suits dry or dehydrated skin that wants moisture without heaviness, and its lighter water cream finish also works for combination skin. The Expert Protection toner and lotion make a steady daily base for most skin types, so they are a safe starting point if you are unsure.
How do I use the Raspberry Lip Sleeping Mask?
Apply a thin layer to your lips before bed and leave it on overnight so lips feel softer by morning. The 20g size lasts a long time because each use is a small amount. It sits at the end of an evening routine, after your face care.
