Skincare trends come and go, but only a few become as popular as skin flooding. Over the past few years, the term has gained significant attention thanks to social media and Korean skincare, where it has become synonymous with intensive skin hydration.
At first, the name may sound a little confusing. In reality, the concept behind skin flooding is surprisingly simple. It involves layering hydrating skincare products onto slightly damp skin to maximise hydration and improve overall skin comfort. Although skin flooding is often presented as a new trend, it is actually based on techniques that have been part of Korean skincare routines for many years.
The term "skin flooding" describes the idea of thoroughly saturating the skin with hydration. The goal is not to use as many products as possible, but to layer lightweight hydrating formulas so the skin can absorb moisture effectively and retain it for longer.
Unlike some skincare trends, skin flooding does not rely on harsh treatments or powerful active ingredients. Instead, it focuses on hydration, soothing the skin and supporting the skin barrier. This is one of the reasons why it has become particularly popular among people experiencing dehydration, tightness or increased skin sensitivity.
One of the main reasons is that dehydrated skin has become increasingly common. Air conditioning, central heating, active skincare ingredients, cold weather and modern lifestyles can all contribute to increased moisture loss, leaving the skin feeling tight, dry or tired.
Skin flooding offers a straightforward solution that can easily be incorporated into an existing skincare routine without the need to buy a large number of new products.
The method is based on a simple principle. After cleansing, lightweight hydrating products are applied one after another while the skin remains slightly damp rather than completely dry.
A typical routine often includes a hydrating toner, followed by a serum and then a moisturiser to help lock hydration into the skin. Each layer contributes to overall skin comfort and supports the skin's ability to retain moisture.
There is no fixed number of steps. The aim is not to create the most elaborate routine possible, but to adapt it to your skin's individual needs.
Most skincare routines already include some form of hydration — and rightly so.
The key difference lies in the emphasis on layering lightweight products and applying them at the right time. For some skin types, several thin hydrating layers may feel more comfortable than one rich cream.
This philosophy closely reflects Korean skincare, which has long focused on lightweight textures and carefully layered routines. The result may not only be better hydration but also skin that feels comfortable without becoming heavy or greasy.
Many products recommended for skin flooding contain hyaluronic acid, well known for its hydrating properties. Other popular ingredients include glycerin, panthenol, beta-glucan and Centella asiatica (CICA).
These ingredients are valued for helping to improve hydration, support the skin barrier and enhance overall skin comfort. As a result, skin flooding is often recommended for dehydrated, sensitive or compromised skin.
As with most skincare trends, there is no universal answer. Many people find skin flooding especially beneficial during the winter months or whenever their skin feels drier than usual. It can also work particularly well for dehydrated skin that needs extra hydration.
However, not every skin type requires multiple hydrating layers. If your current routine works well and your skin is healthy and comfortable, there is no need to add extra steps simply because they are trending on social media.
A common misconception is that skin flooding means applying five or six hydrating products in succession. In reality, that is not the essence of the technique. Even a simple routine can be highly effective. Choosing suitable products that your skin tolerates well is far more important than the number of products you use.
One reason for the popularity of this trend is its close connection with supporting the skin barrier. When the skin is dehydrated or sensitive, the aim is to replenish moisture while helping the skin retain it more effectively.
For this reason, skin flooding is often discussed alongside topics such as skin barrier repair, sensitive skin and long-lasting hydration. However, it should not be viewed as a solution to every skin concern. It is simply one approach that may help improve skin comfort and support healthy skin function.
In some ways, yes—but mainly in terms of its name rather than the technique itself. Many of the methods now described as skin flooding have been part of Korean skincare for years. Layering lightweight hydrating products is far from new and has been practised long before it became a social media trend.
That does not mean the trend is without value. On the contrary, it has highlighted the importance of hydration and reminded people that healthy-looking skin often needs fewer active ingredients and greater attention to its basic needs.
Skin flooding is a simple skincare technique focused on intensive hydration through layering lightweight products. Although it is often promoted as a new trend, its principles are rooted in long-established Korean skincare practices and the understanding that well-hydrated skin tends to be stronger, more comfortable and healthier-looking.
For many skin types, skin flooding can be an effective way to boost hydration and improve skin comfort. However, it should not be seen as an essential part of every skincare routine. As with most skincare trends, the best results come from a routine tailored to your skin's individual needs—not from the one with the greatest number of steps.
