However, not all forms of zinc oxide are created equal. In this article, we will explore the difference between non-nano and nano zinc oxide and why non-nano zinc oxide is the preferred choice for many consumers. Zinc oxide is a mineral that has been used for centuries to protect skin from harmful UV rays.

Nano-HA have a high affinity to bind to substances due to an increased surface area which may improve remineralisation and reduce sensitivity as HA with a 20–50 nm size matches the nano-sized defects due to acidic erosion at the enamel surface [32,36]. Nano-HA are also thought to be more effective than micro-HA in biofilm management.
This lightweight, non-nano zinc oxide facial sunscreen lotion provides daily protection from the sun’s damaging UV rays. With a pink-hued formula that blends in translucent on most skin tones and works beautifully on sensitive, acne-prone or oily skin, Zincscreen provides daily physical sunscreen protection and is full of clean ingredients
Dr. Gmyrek explains that because zinc runs on the goopy, thick side, a lot of companies have made the molecule super, super small. “These micronized or nano-zinc oxide sunscreens are preferred
Highlights: Broad-spectrum protection from this reef-safe, FDA-approved sunscreen that protects against all three types of UV rays (UVB, UVA2, and UVA1). Vegan and cruelty-free, with non-nano zinc and organic ingredients. Water-resistant to 80 minutes and suitable for kids and adults.
A) W/O emulsion, coated ZnO (20% ZnO, Umicore, left image, TEM, Reference: 18) ZnO nanoparticles have different shapes (rod-like, star-like and isometric) and a broad size distribution range of 30–150 nm. The ZnO particles were present mainly as clusters.

You could have a product with 25% zinc oxide with really bad UVA protection, and one with 12% zinc oxide that provided decent UVA protection. The only way to know how much UVA protection a particular product provides is for a brand to actually take measurements of UVA transmittance.

The zinc oxide nanoparticles were synthesized using zinc acetate as the precursor and sodium hydroxide as the reducing agent. A 0.1 M of zinc acetate homogenous mixture was dissolved in double-distilled water at pH of 11 for 2 h with the aid of magnetic stirrer. The 0.1 M NaOH solution was slowly added into the zinc acetate solution under
