🌞 What are Sunscreens?
Sunscreens are topical products designed to protect the skin from the harmful effects of ultraviolet (UV) radiation. There are 2 main types of UV radiation that can affect the skin: UVA and UVB.
UVA rays penetrate deep into the skin and are primarily responsible for premature aging and wrinkling, while UVB rays cause sunburn and play a significant role in developing skin cancer.
Sunscreens work by either absorbing, reflecting, or scattering the sun's rays on the skin, thus offering protection against these damaging effects. Formulated in various textures such as creams, gels, sticks, and sprays, sunscreens are an indispensable part of daily skin care, especially in products from Korea, where they are often combined with other skin-benefiting ingredients.
🤔 Mineral vs. Chemical Sunscreens
Korean sunscreens can be categorized into two types: mineral and chemical. Mineral sunscreens use physical blockers such as zinc oxide or titanium dioxide to reflect UV rays, while chemical sunscreens work by absorbing and transforming the sun's rays into heat energy.
Both types have their pros and cons. Mineral sunscreens are generally considered safer for sensitive skin, less likely to cause irritation and have a longer shelf life. However, they can leave a white cast on darker skin tones and may feel heavier on the skin.
On the other hand, chemical sunscreens have a more lightweight texture, making them easier to apply and reapply throughout the day. They also tend to blend seamlessly into all skin tones without leaving a white cast. However, they can potentially irritate sensitive skin and may not be as stable in high temperatures.
📝 Criteria for Selection
SPF and PA Ratings
The Sun Protection Factor (SPF) measures how well a sunscreen will protect skin from UVB rays, the kind that causes sunburn and contributes to skin cancer.
The PA rating system, which is used widely in Asia, measures the level of protection from UVA rays, with more plus signs indicating greater protection. Products chosen have high SPF and PA ratings to offer broad-spectrum protection.
SPF rangings start at 15 and can go up to 100, with higher numbers indicating more protection. PA ratings range from PA+ to PA++++, with the latter offering the highest level of UVA protection. The higher the SPF and PA ratings, the better protected your skin will be from sun damage.
Texture and Application
A sunscreen’s feel and finish on the skin can determine how often it will be used. The selected sunscreens vary from lightweight serums to moisturizing creams, ensuring a pleasant application regardless of skin type.
Suitability for Skin Types
Different formulations are better suited for specific skin conditions, such as dry, oily, or acne-prone skin. Each product listed caters to these unique skin needs while providing excellent sun protection.
