Zinc oxide works as a physical sunscreen, meaning it sits on top of the skin and reflects or scatters UV rays away from the skin, rather than being absorbed into the skin like chemical sunscreens. This makes it suitable for sensitive skin and offers immediate protection upon application.
Zinc oxide is also photostable, meaning it does not degrade or lose its effectiveness when exposed to sunlight, making it an excellent choice for long-term sun protection.
Zinc oxide is a highly effective and reliable ingredient for sun protection, and it is often recommended by dermatologists for its safety and efficacy.
In addition to its sun protection properties, zinc oxide offers several other benefits for the skin:
1. Soothing and calming: Zinc oxide has anti-inflammatory properties that can help soothe and calm irritated or inflamed skin. It is often used to alleviate conditions such as sunburn, rashes, and redness.
2. Wound healing: Zinc oxide has been shown to promote wound healing and tissue repair. It can help to reduce the risk of infection, minimize scarring, and accelerate the healing process of cuts, scrapes, and minor burns.
3. Oil control: Zinc oxide has mild astringent properties that can help to absorb excess oil and sebum from the skin, making it beneficial for those with oily or acne-prone skin. It can help to mattify the skin and reduce shine, without clogging pores or causing breakouts.
4. Antimicrobial: Zinc oxide has antimicrobial properties that can help to inhibit the growth of bacteria and fungi on the skin's surface. This can be beneficial for preventing and treating acne, as well as other bacterial or fungal skin infections.
5. Barrier protection: Zinc oxide forms a protective barrier on the skin's surface that helps to shield it from environmental aggressors such as pollution, UV radiation, and harsh weather conditions. This barrier function helps to keep the skin healthy, hydrated, and protected.
Overall, zinc oxide is a versatile ingredient that offers multiple benefits for the skin beyond sun protection. Its soothing, healing, oil-controlling, antimicrobial, and barrier-protecting properties make it a valuable addition to skincare formulations for various skin concerns.
