How Does Rainwater Affect Your Skin?

Is rainwater really clean and harmless? Da Nang is going through a very rainy spell because of recent storms, creating ideal conditions for bacteria and fungi to thrive. This leads to problems such as dry skin, allergies, irritation, acne and more – and these are just some of the common issues we see in our daily consultations with clients.

So let Lunaria share some basic skincare know-how for this damp, changeable season, to help protect your skin from the effects of the weather!

How Rainwater Affects Skin, and What Skin Is Like in the Rainy Season

You may not know it, or may not take it seriously, but rainwater often contains a lot of pollutants, bacteria, dirt and even heavy metals. With frequent exposure, it is hard for skin to avoid irritation, rashes and itching – especially if you have sensitive skin.

Specifically, rainwater can lead to a number of skin problems, such as:

• Increased humidity: Rain raises the humidity in the air, which throws the skin off balance and makes it produce more oil than usual. If you have oily or combination skin, you will notice this clearly.
• Irritation: Rainwater often carries dust particles, bacteria and other pollutants from the air. On contact with the skin, these can cause irritation, dermatitis or allergic reactions. That is why skin often feels itchy and uncomfortable, or turns red or bumpy, after you get caught in the rain.
• Triggering acne: Dirt and bacteria in rainwater also increase the risk of breakouts. Bacteria and impurities clog pores more easily, leading to acne.
• A worn-down skin barrier: caused by direct contact with rainwater. The strong, repeated friction of raindrops hitting the skin can easily damage its surface. At the same time, direct contact with rainwater strips away the skin's natural protective oils, leaving it dry, flaky and uncomfortably itchy.

Tips for Caring for Your Skin in the Rainy Season

Always keep the following precautions in mind to protect the health of your skin:

1. Always keep your skin clean

The first and most important step in rainy-season skincare is keeping your skin clean. Wash any skin that has been exposed to rain as soon as possible. Rainwater cannot fully wash away your makeup, so use a makeup remover to clear away cosmetics and residue. Choose a gentle cleanser free of fragrance and irritants, and massage lightly to remove dirt and excess oil. For oily skin, you can choose an oil-control cleanser.

Special Cleansing Gel – a soap-free foaming cleanser for a deep clean

Skin can produce more oil in the rainy season because of the higher humidity, so exfoliating once or twice a week is essential. It removes dead skin cells from the surface and prevents clogged pores. Exfoliating also helps your skin absorb the serums and treatments in the next step. This is a very important rainy-season tip that you shouldn't skip.

2. Rebalance your skin's pH

Every time your skin is exposed to rain, it needs to be cleansed. However, cleansing too often can upset your skin's pH balance. Using a toner after cleansing helps restore it. A gentle, alcohol-free toner will also help remove excess oil and give a deeper clean.

3. Focus on soothing and moisturising your skin

Use a moisturiser rich in ceramides and hyaluronic acid to restore the skin barrier. It also keeps the skin hydrated and prevents water loss. Even though your skin may produce more oil in the rainy season, don't skip moisturising – it keeps your skin balanced. Choose a moisturiser that absorbs easily and won't clog pores.

Using a hydrating mask once or twice a week deeply moisturises and soothes the skin. This helps limit irritation from contact with rainwater and from cleansing too often.

4. Apply sunscreen

Even in the rainy season, you shouldn't skip sunscreen to reduce the effects of UV rays. UV rays can still harm your skin on cloudy, sunless days.

5. Care for your skin from within

- Drinking plenty of water is an effective way to care for your skin in the rainy season

Drinking enough water in the rainy season is very important for keeping your skin hydrated. Damp, cold weather can dry out the skin, and drinking enough water helps maintain moisture from within. Staying well hydrated also helps your body flush out toxins, which improves the function of your organs and makes your skin look healthier.

To stay well hydrated, drink about 8 glasses of water a day, and top up with foods such as fruit, leafy greens and fresh juices.

– Build a healthy diet and rest routine

A healthy, nutritious diet, including drinking enough water every day, is always the simplest and most effective secret to keeping your skin healthy and beautiful from within.

Getting enough sleep is also very important to avoid dark circles. While you sleep, your skin regenerates and produces new cells, helping restore a fresher, more youthful complexion.

6. Avoid direct contact with rainwater

Rainwater can contain pollutants from the air and the environment, so avoid letting it come into direct contact with your skin. A handy tip: wear a (water-resistant) face mask to keep rain from splashing directly onto your face.
