5 Everyday Habits That Make Eczema Worse

A long hot shower might feel like exactly what your itchy skin needs. The heat provides temporary relief, and the sensation of water on irritated skin can feel soothing. But what is happening underneath the surface is the opposite of helpful.

Hot water dissolves the natural oils that form part of your skin barrier. These oils are not just there for moisture. They are part of what keeps irritants and allergens out. When you strip them away with a hot shower, your skin is left more porous, more reactive, and drier than before you got in. The longer and hotter the shower, the more damage is done.

In Hong Kong, this is compounded by the fact that many people immediately step from a hot shower into a heavily air-conditioned room, which accelerates moisture loss from the skin surface even further.

This one is genuinely hard. The itch that comes with eczema is not a mild nuisance. It is intense, persistent, and for many people it is worst at night when there is nothing to distract from it. Scratching provides brief relief, and the urge can be almost impossible to resist.

But scratching creates a cycle that is difficult to break. When you scratch, the skin surface breaks. Broken skin triggers the immune system to respond, releasing chemicals that intensify the itch signal. So you scratch more, which breaks the skin further, which intensifies the itch again. This is called the itch-scratch cycle, and it is one of the main reasons eczema flare-ups escalate and take longer to settle.

Scratching also opens the skin to infection. Staphylococcus aureus bacteria, which are found on nearly all eczema-affected skin, can enter through breaks in the skin and cause a secondary infection that makes the flare significantly worse.

Many people moisturise once in the morning and consider the job done. For normal skin, that might be fine. For eczema-prone skin, it is not nearly enough.

Eczema-affected skin has a compromised barrier, which means it loses water much faster than healthy skin does. The gap between your morning application and the evening is long enough for the skin to dry out significantly, become itchy, and be more vulnerable to irritants throughout the day. In a city like Hong Kong, where you are constantly moving between humid outdoor air and dry air-conditioned spaces, that drying effect is even more pronounced.

The Anitch recommendation of at least three times daily is not an arbitrary number. It is based on the practical reality of how quickly compromised skin loses moisture, and how consistently the ANESININ formula needs to be present on the skin to deliver its long-term barrier repair benefits.

This habit is closely related to the previous one, but it deserves its own section because it catches a lot of people off guard. You might moisturise regularly, but if you are doing it fifteen or twenty minutes after your shower while you make breakfast, get dressed, or check your phone, you are missing the most important window.

When you step out of the shower, your skin is warm and slightly moist. This is when it absorbs moisture most effectively and when a moisturiser can form the strongest barrier seal. As the minutes pass and the water on your skin evaporates, the skin surface actually becomes drier than it was before you showered. The evaporation process pulls moisture from within the skin as it goes.

Two to three minutes is the general window. After that, you are working against the process rather than with it.

Fragrance is one of the most well-documented skin irritants for people with eczema, and it appears in far more products than most people realise. Body wash, shampoo, laundry detergent, fabric softener, hand soap, and skincare products can all contain fragrance ingredients, sometimes listed as "parfum" or "aroma" on the label, which covers a mix of multiple chemicals.

The problem is not just synthetic fragrance. Natural fragrances, including essential oils like lavender, eucalyptus, and citrus extracts, are also common eczema triggers. The word "natural" on a label does not mean safe for sensitive skin.

Denatured alcohol is another ingredient to watch for. It is used in many toners, mists, and lightweight skincare products to create a fast-drying, refreshing feel, but it strips moisture from the skin and disrupts the barrier over time. Sodium lauryl sulphate, found in many foaming cleansers and shampoos, is similarly problematic for eczema-prone skin.

The impact of these ingredients is cumulative. Each individual product might seem fine in isolation, but if your body wash, laundry detergent, and hand cream all contain fragrance, your skin is being exposed to multiple irritants every single day.
