From ingredients of coconut oil, aloe vera, beeswax or avocado oil, almonds, olives, tomatoes, even from loofah…, many groups “tip” to women how to create a jar of anti-wrinkle cream Sunlight with cheap price, natural, safe, especially for people with sensitive skin. “Confidently use without worrying about irritation and allergies” – an account shared. MSc.BSCK2 Nguyen Quang Minh, Deputy Dean of the Department of Research and Application of Stem Cell Technology – National Hospital of Dermatology, said his opinion on homemade sunscreen above is wrong. “The ingredients in homemade sunscreen can easily cause allergies because they cannot remove the impurities in the ingredients used,” said Dr. Minh. Sunscreens from olive oil and beeswax are confirmed by beauty forums to be safe and easy to make. Illustration The expert explained: It is conceivable that, with professional manufacturers, when extracting avocados to put in sunscreen ingredients, they can only take some of the active ingredients, but not all. The same goes for other natural ingredients. “ The combination to increase the effectiveness has also been researched, tested and specifically evaluated, different from arbitrarily choosing ingredients that we believe can achieve sun protection.” , BS Minh analyzed. There are 7-25 different ingredients in sunscreen. Therefore, for each person, it is necessary to determine the criteria to choose the right one, not merely based on a certain formula to test on their facial skin with the belief that “natural products should be safe”. . Sunscreens are divided into two main categories: chemical sunscreens and physical sunscreens. In particular, homemade sunscreens with natural ingredients are classified as chemical sunscreens. This type of sunscreen contains organic ingredients, reduces UV rays, avoids damage to the skin, and has a soft, comfortable texture, but is less sustainable under the influence of the environment. Physical sunscreens have metal oxide ingredients (such as titanium oxide, zinc oxide), the nature of use is often sticky (due to the thick cream texture) and whiter tones … Physical sunscreen (Sunblock) is an inorganic sunscreen that has the ability to reflect UV rays, preventing UV rays from penetrating the skin. The main ingredients in physical sunscreens are usually Zinc Oxide and Titanium Dioxide. Chemical sunscreens (Suncreen) will absorb UV rays to decompose and treat before they cause damage to the skin. The main ingredients in chemical sunscreens are usually: avobenzone, oxybenzone, Tinosorb, octylcrylence… Studies around the world show that physical sunscreens are very benign while chemical sunscreens are more likely to cause allergies and are less commonly prescribed by dermatologists for people with sensitive skin. Dr. Minh shared, many people think that homemade sunscreen is safer because of its natural ingredients, but the truth is that doctors often recommend People with easily irritated skin, acne-prone skin should use physical sunscreen instead of chemical sunscreen because it can make the condition worse. . A sunscreen product must also be concerned with the SPF – showing the time and coverage of the sun. Specifically, sunscreen with SPF 30+ can cover and protect skin 93 – 94%, SPF 50+ can cover and protect 97 – 98%… One SPF is equivalent to 15 minutes of protection. Based on that, the user considers which cream is suitable for the day’s activities. For example, when going to the beach, it is necessary to choose a sunscreen with a high SPF, from 50+, and proactively reapply the cream to protect your skin. These are important information when choosing sunscreen, tested and announced by manufacturers. Meanwhile, with homemade sunscreen, how effective and how long it protects, has not been specifically evaluated.

Sunscreen – the indomitable object on a hot summer day

As one of the indispensable products on a summer day, sunscreen helps people protect the skin, avoiding the effects of ultraviolet (UV) rays in the sun. Ultraviolet rays are divided into 3 types, UVA, UVB, and UVC rays. In which, UVA, UVB rays can pass through ozone layer and harm human health; UVC rays are blocked by the ozone layer, unable to penetrate the ground. Therefore, when going outdoors, our skin will be affected by UVA and UVB rays, which darken the skin, damage the skin, accelerate the aging process and increase the risk of skin cancer.

Sunscreen helps people protect the skin from the effects of ultraviolet (UV) rays in the sun.

To protect the skin from the effects of UV rays, consumers who choose sun protection products, including sunscreens, should pay attention to choosing a cream with a higher SPF number, which protects the skin from UV rays. higher. For example, SPF 2, skin protection ability is 50%; SPF 15, skin protection ability is 94%; SPF number is 100, the ability to protect the skin is 99%. However, consumers should not choose products with the SPF number too high, as it can cause skin irritation. Therefore, consumers only need to choose at 30, 50 for the best.

Besides, when buying a sunscreen, consumers also pay attention to the PA index (denoted PA ++, +++…) on the sunscreen. The more + sign, the better the resistance to UV rays.

However, consumers also note, it is possible that the sunscreen is suitable for one person, but irritates the skin for another. So, consider before choosing this skin protection product.

Experts warn against the harmful effects of sunscreen if used in the wrong way

Recently, the US Food and Drug Administration (FDA) recommends a sunscreen with a maximum SPF of 50-60 for the best skin protection. Two safe and effective ingredients in sunscreen are zinc oxide, titanium dioxide. Meanwhile, the ingredients aminobenzoic acid (PABA) and trolamine salicylate have been warned by the FDA to be unsafe.

FDA also requires manufacturers to demonstrate the safety of 12 sunscreen ingredients: cinoxate, dioxybenzone, oblulizole, homosalate, meradimate, octinoxate, octisalate, octocrylene, padimate O, sulisobenzone, oxybenzone, avobenzone. Therefore, consumers need to pay close attention to the ingredients on the product label when choosing sunscreen. Safe sunscreens approved by the FDA include sprays, oils, lotions, creams, gels, avocados, glues, ointments, and waxes. The agency says more information is needed before drawing a conclusion with its powdery sunscreen.

The US Food and Drug Administration (FDA) recommends a sunscreen with a maximum SPF of 50-60 for the best skin protection.

To prevent skin cancer, Associate Professor, Dr. William W. Huang, Wake Forest School of Medicine, recommends applying sunscreen about 30 minutes before going out in the sun and reapplying at least every two hours. Facial skin is a sensitive, vulnerable place to ultraviolet rays leading to skin cancer, so priority is given to applying cream on the face.

Ohio-based dermatologist Amy Kassouf also noted that sunscreen should be applied to small areas of skin like the eyelids, lips, and ears. Most lip cosmetics do not contain SPF. The skin on the edges of clothing is also often sunburned, so more sunscreen should be applied, according to dermatologist Jennifer Stein in New York. People with sensitive skin should use sunscreens containing zinc oxide and titanium dioxide in place of the chemical sunscreen ingredient.

According to chemist and founder of the beauty website The Beauty Brain – Perry Romanowski, expired sunscreens will no longer be able to protect your delicate skin. At this time, sunscreen, whether physical or chemical, has no longer reached the SPF level as advertised. Meanwhile, chemical sunscreens with ingredients containing oxybenzone, avobenzone and homosalate can oxidize and become less effective. Physical sunscreens contain zinc oxide or titanium dioxide, although there is no oxidation, they still lose the quality and effectiveness of sun protection. Simply put: while the sunscreen ingredients are active, they may not be able to function properly in skin protection.

Also sharing about the harmful effects of sunscreen, Dr. Erin Gilbert said that when you open the bottle of sunscreen with dirty hands, or open too many times can cause bacteria to enter the product. Decreases the quality of the cream and causes acne breakouts when used.

Dr. Gilbert recommends that if you leave sunscreen in a hot place such as in a car, swimming pool or in a bag, it will expire more quickly due to high temperature environments. In this case, you should replace it every few months to ensure that the sunscreen will always work effectively.
