What is sun lotion and what is its composition?
Sun milk, commonly known as sun lotion or sun cream, is a skin care product designed to protect the epidermis against the harmful effects of the sun's ultraviolet (UV) rays. Its composition varies from brand to brand, but it generally contains UV filters, moisturizers, antioxidants and soothing ingredients such asaloe vera or vitamin E. These components work together to moisturize the skin, prevent sunburn and reduce the risk of skin cancer.
What are the main benefits of sun milk?
There are several key benefits to using sun milk:
How to choose the right sun lotion for your skin type?
To choose the right sun milk for your skin type, follow these tips:
How much sun lotion should I apply, and how often?
For effective protection, we recommend applying around 35 ml of sun milk all over the body, and reapplying every two hours or immediately after swimming, sweating or using a towel. It's essential to cover all exposed parts of the body, including the face, ears, hands and feet.
What are the common mistakes to avoid when using sun milk?
Common mistakes include:
Can sun milk be used all year round?
Absolutely, the use of sun milk is recommended all year round, as UV rays can penetrate clouds and windows, meaning that the skin is exposed even on overcast days or while driving. For daily protection, a sun protection factor (SPF) of 15 or more is recommended.
How to store sun milk to maintain its effectiveness?
To store your sun milk effectively, keep it in a cool, dry place away from direct sunlight. Check the expiry date regularly and replace the product every year to ensure optimum protection.
How does sun milk protect against UVA and UVB rays?
Sun milk works by incorporating solar filters that absorb, reflect or disperse ultraviolet rays. These filters can be chemical or physical. Chemical filters absorb UV rays before they reach the skin, while physical filters, such as zinc oxide or titanium dioxide, reflect and disperse UV rays. It's crucial to choose a broad-spectrum product for protection against UVA, associated with skin aging, and UVB, mainly responsible for sunburn.
Can sun milk be used on children?
Yes, it is possible to use sun milk on children, but it is advisable to choose formulas specially designed for their delicate skin. These products are generally hypoallergenic, fragrance-free, and use physical rather than chemical filters. It's also advisable to choose a sun lotion with a high sun protection factor (SPF ) of at least 30, to ensure optimum protection against the sun's harmful rays. Reapply every two hours, and after every swim or physical activity.
Does the sun milk expire, and how do I identify this date?
Yes, sun milk has an expiry date, usually located on the packaging or printed directly on the tube. After this date, the active ingredients, notably the sunscreens, can begin to degrade, making the product less effective. It is important to check the condition of the sun milk regularly, to note any changes in texture or smell, and to replace it if necessary to maintain adequate sun protection.
Can I apply sun milk to wet skin?
Some sun milk formulations are specially designed to be applied to wet skin, ideal for aquatic or sporting activities. These products use a technology that enables the milk to penetrate and create a protective barrier even on wet skin, without running. It's important to read labels and choose a water-resistant product if you plan to be in contact with water or perspire.
What is the environmental impact of different types of sun milk?
The environmental impact of sun milks, especially those containing chemical filters, can be significant. Some ingredients, such as oxybenzone and octinoxate, are of concern because they can contribute to the degradation of coral reefs. To minimize this impact, we recommend choosing sun milks with physical filters or biodegradable, oxybenzone-free formulas. What's more, using certified ecological or organic products can also help reduce the ecological footprint of our sun protection habits.
