After sun: why it's essential after sunbathing

When we think about protecting our skin from the sun, we usually focus on sunscreen. However, skincare doesn't end when we leave the beach, the pool, or a day outdoors. After sun exposure, our skin needs soothing, hydration, and repair. This is where after-sun lotion comes in.

After-sun lotion isn't just a moisturizer. It's specifically formulated to help your skin recover from the effects of sun, heat, sweat, chlorine, or sea salt. Using it correctly can make a big difference to your skin's health and appearance during the summer.

What happens to the skin after sun exposure

Even when using sun protection, the skin is subjected to a series of aggressions during exposure:

• Water loss

• Increased skin temperature

• Oxidative stress

• Feeling of tightness

• Possible redness

• Alteration of the skin barrier

The sun generates free radicals, molecules that damage cells and accelerate skin aging. Furthermore, heat and prolonged exposure promote dehydration, making the skin feel drier, rougher, or more sensitive.

Difference between a moisturizer and an after-sun lotion

A conventional moisturizer provides water and comfort, but an after-sun lotion is designed to work after sun exposure.

It usually contains ingredients with the following action:

• Soothing

• Refreshing

• Repairer

• Antioxidant

• Moisturizing

Therefore, it is especially useful when the skin has been exposed to the sun for several hours or feels hot, tight, or red.

Benefits of after sun

• It soothes the skin

Ingredients such as aloe vera, panthenol, or thermal water help reduce the burning sensation and soothe the skin.

• Deeply rehydrates

After sun exposure, skin loses water. After-sun lotion helps restore hydration and prevents peeling.

• It helps repair the skin barrier.

A damaged skin barrier leaves the skin more vulnerable. After-sun products help to strengthen it.

• Prolongs a more beautiful tan

Hydrated skin flakes less and maintains a more even tone.

• It reduces the feeling of heat.

Many formulas have a cooling effect, which is very pleasant after sun exposure.

Recommended ingredients in a good after-sun lotion

When choosing an after-sun product, it's advisable to look for ingredients such as:

• Aloe vera: soothing and moisturizing.

• Panthenol: helps repair and soften the skin.

• Allantoin: soothes irritation.

• Bisabolol: reduces the feeling of discomfort.

• Thermal water: refreshes and soothes.

• Vitamin E: antioxidant, helps fight oxidative damage.

• Hyaluronic acid: retains water and improves hydration.

Light textures, such as gel or lotion, are usually very comfortable in summer.

How to apply after sun correctly

For best results, apply after showering, on clean, dry skin.

Ideally:

• Shower with lukewarm water, not hot.

• Dry the skin gently, without rubbing.

• Apply after-sun lotion generously.

• Repeat application if skin remains tight or hot.

It can also be applied at night to promote recovery while we sleep.

What not to do after sunbathing

After intense sun exposure, it is advisable to avoid:

• Exfoliate the skin

• Using perfumes or products containing alcohol

• Very hot showers

• Tight clothing if the skin is irritated

• Avoid sun exposure again if redness develops.

If a burn, blisters, or severe pain appears, it is advisable to consult a professional.
