Photoprotection that adapts to your day-to-day life

When choosing a daily sunscreen, it’s especially important to understand your skin’s individual needs, such as where and when you’ll be using sun protection.

Your ideal sunscreen is one that you enjoy applying, and that adapts to your lifestyle!

ISDIN Fusion Water and ISDIN Fusion Water Urban not only adapt to your skin, they are also designed to suit your day-to-day life.



Time spent outdoors

Intense sunlight exposure over long periods of time, such as when we exercise, enjoy the sunshine in summer, work outdoors, or go for long walks, puts our skin at increased risk and can cause sunburn, which is mostly produced through UVB radiation exposure. The new, improved Fusion Water will be your skin’s best friend under these conditions.

  • check-icon SPF50 UVB
  • check-icon Does not sting eyes
  • check-icon Improved! Immediate absorption
  • check-icon Improved! Intense hydration



Urban environments

UVA radiation and blue light, which our skin is exposed to every day in city environments, contribute to the negative effects of pollution on our skin. This accelerates the appearance of hyperpigmentation or dark spots on our skin, along with premature skin aging, known as photoaging. The new Fusion Water Urban is your ideal choice to help prevent this.

  • check-icon Protection against air pollution
  • check-icon Anti-fatigue effect on the skin
  • check-icon Excellent makeup base
  • check-icon SPF30 UVB
  • check-icon Does not sting eyes

What are the factors that influence photoaging?

Solar radiation is not the only cause of photoaging. Other factors such as air contamination and pollution are also related to premature aging of the skin. Want to know how? Read on!

Solar radiation is composed of electromagnetic waves which form part of the sun’s electromagnetic spectrum. These waves are divided based on their length and frequency.

There are various types of radiation on the solar spectrum which reach Earth, including ultraviolet radiation (UV). UV radiation can be ultraviolet A (UVA), ultraviolet B (UVB) and ultraviolet C (UVC). The latter does not penetrate the atmosphere, so we will focus on the two types which do, and which reach our skin: UVB and UVA radiation.


5% of UVB radiation penetrates the atmosphere and it is the principal cause of short-term damage to the skin, like sun damage and tanning. It is also the principal cause of most skin cancers.

During the year, this type of radiation varies more and is more unstable than UVA radiation: in summer the amount of radiation is higher than it is in winter. It does not penetrate windows, so it does not affect our skin when we are indoors.

35% of UVA radiation penetrates the atmosphere, where it is responsible for long-term damage, such as photoaging of the skin, hyperpigmentation, immunosuppression, and long-lasting tanning. It also contributes to the emergence of skin cancer.

This type of radiation is much more stable throughout the year and can pass through windows, meaning radiation can reach our skin as we drive, or as we work at the office.

Blue light is classified as visible light on the sun’s electromagnetic spectrum, and, like UVA radiation, it can pass through windows. It is the cause of more intense, prolonged pigmentation, particularly in those with darker skin.

- There are over 7.3 billion people around the world, 54% of whom live in urban areas.

- At least 34,500 million tonnes of CO2 are emitted annually worldwide.

- There are currently more than 1.2 billion cars in the world.

- In just a single day, the whole world consumes over 11 billion cigarettes.

What effects does pollution have on the skin? What effects does pollution have on the skin? Exposure to environmental pollution is related to premature aging of the skin, and a 25% increase in hyperpigmentation and dark spots. Pollution produced by vehicles, industry, and cigarette smoke emits substances called polycyclic aromatic hydrocarbons, very small particles that become embedded in the surface layers of the skin, triggering a process called oxidative stress and altering the gene expression of certain cells relevant to skin aging and pigmentation.

Signs of aging in the skin associated with pollution:

- Dehydrated skin with increased transepidermal water loss. - Redness. - Hypersensitivity. - Inflammation and hyperpigmentation that turn the skin gray. - Reduction of collagen and elastin levels, leading to the formation of wrinkles in the skin. - Stimulation of melanin, causing changes in skin tone (melasma).
