Summer arrives full of sunshine, outdoor games, and endless days at the beach or pool. For families with young children, this time of year is synonymous with fun, but also with risks if children's skin isn't properly protected.
Children's skin is much thinner, more delicate, and more vulnerable than adults'. According to the Spanish Association of Pediatrics, 80% of cumulative sun exposure throughout a lifetime occurs before the age of 18. Therefore, sun protection in childhood is not simply a matter of aesthetics: it is a long-term health measure.
Next, we review the most common mistakes families make during the summer and how to avoid them so your children can enjoy the sun safely.
Mistake 1: Using any sunscreen without checking the label
Not all sunscreens are the same, especially for children. One of the most common mistakes is using the same sunscreen for the whole family.
What to look for in a children's sunscreen?
- SPF 50+ (high protection)
- Special formulas for sensitive or atopic skin
- Broad spectrum UVA and UVB protection
- Physical or mineral filters (zinc oxide or titanium dioxide), especially for babies under 2 years old
- Water-resistant texture and no added perfumes
Error 2: Applying it too late or only once a day
Many families apply sunscreen right when they are on the towel or already with their feet in the water, but this greatly reduces its effectiveness.
The correct way : apply sunscreen 30 minutes before sun exposure and reapply every 2 hours, or more frequently if you have been swimming or sweating heavily. Even water-resistant formulas lose effectiveness over time.
Mistake 3: Believing that with cream everything is already done
Sunscreen is not an invincible shield. It must be part of a set of complementary measures:
- Avoid the sun between 12:00 and 17:00
- Wear lightweight long-sleeved clothing, approved sunglasses, and a wide-brimmed hat or cap.
- Prioritize shaded areas or bring an umbrella
- Stay hydrated frequently with water and fresh fruit
Error 4: Exposing babies under 6 months old to direct sunlight
Pediatricians agree: babies under 6 months should not be exposed to direct sunlight, even with sun protection.
Their skin has not yet developed the necessary defenses to withstand ultraviolet radiation. In these cases, the best protection is:
- Keep them in the shade
- Clothing that covers their skin well, is breathable, and is light-colored.
- Hood, parasol or canopy if they are in a stroller
- Do not use sunscreens unless recommended by a doctor.
Error 5: Not applying the correct amount
Another classic mistake: applying too little cream. Studies indicate that, in general, we only use 25-50% of the recommended amount.
Indicative measure :
- Young children: 1 teaspoon per area (face, arm, leg, etc.)
- It covers all areas well: ears, nape of the neck, insteps, behind the knees and the swimsuit line
Error 6: Reusing last year's cream without checking it
Sunscreen products have an expiration date and once opened, they lose effectiveness over time, especially if they have been exposed to heat.
Always check :
- Expiration date
- The PAO (Period After Opening) symbol indicates how many months it lasts once opened.
- Color, texture, or smell: if they have changed, it's best to throw it away.
Error 7: Thinking that if it's cloudy or they already have color, it's not necessary
Clouds do not block UV rays, and water, sand, and snow reflect even more radiation.
Furthermore, having dark skin does not mean it is protected. A tan is already the body's response to sun damage.
In summary: keys to effective sun protection for children
| Recommendation | Why is it important? |
| SPF 50+ children's sunscreen with physical filters | More sensitive skin |
| Apply 30 minutes before and reapply every 2 hours | Maximum effectiveness |
| Avoid sun during peak hours | Peaks in UV radiation |
| Complement with clothing, shade and hydration | Comprehensive protection |
| Do not expose babies under 6 months to direct sunlight | High risk |
“Childhood is when we must protect our skin the most. A single sunburn in a child doubles the risk of skin cancer in adulthood.”
— Dr. Núria Llompart, pediatric dermatologist
Protecting our children's skin isn't just a gesture of care; it's an investment in their lifelong health. Summer can and should be enjoyed to the fullest, but always with awareness, responsibility, and good habits.
