• April 26, 2024

The function of our skin is to protect our body from external aggressions such as cold or heat. For this reason, we must take care of it and keep it in perfect condition throughout the year, especially in the summer months, which makes it necessary to use a sunscreen.

Therefore, in accordance with recommendations issued by the Photobiology Committee of the Skin Cancer Foundation , we will tell you what to consider when choosing your sunscreen or sunscreen.
 

1. Chemicals It is not advisable to choose a sunscreen whose formula includes perfumes, preservatives or parabens. Both chemical and physical sunscreens, composed of nanoparticles, can cause the release of free radicals.
 

2. Vitamin A. According to scientists from the Food and Drug Administration , Retinyl Palmitate (which is absorbed into Retinol when absorbed) exposed to ultraviolet light forms free radicals and causes mutations in DNA, making skin cancer more likely.
 

3. PABA. The products with para-aminobenzoic acid (PABA) are not recommended, as it can cause allergic reactions, mainly in children. These are manifested as redness and itching during the first 24 hours after its application, according to a study published in Journal of the American Academy of Dermatology.
 

4. Oxybenzone. It is found in 60% of sunscreens. According to a study conducted by the United States Center for Disease Control , this chemical has been associated with allergies, hormonal disruption (estrogenic effects), cell damage, and low weight in babies whose mothers were exposed to the chemical during pregnancy.
 

5. Octinoxate. It is an endocrine disruptor, an imitator of estrogen, which helps the penetration of other chemicals.
 

6. Expiration. It is important that you review the period of life or expiration date of the sunscreen, since you acquire it and open it, to ensure a safe exposure of the skin to the sun.
 

7. Never use natural remedies dubious, such as coconut oil, lemon, soft drinks or beer, since in addition to not offering protection, they can increase sun damage and disproportionately.

Remember that you should always check the label of a sunscreen before buying it, in addition to applying it 30 minutes before exposing yourself to the sun. The amount will vary according to the body surface; it is estimated that for an average adult about 35 ml are required. The ideal is to apply it every 30 minutes, and those against water every 90 minutes.
