I have found several search results related to nail design in 2023, product details, positive and negative aspects, and ingredients or materials. Here are the key findings:

• Nail design trends for 2023 include intricate details, bold colors, and the use of different materials to create unique and unexpected looks.
• Nail products such as nail polish, nail polish removers, and artificial nails have shown to have some adverse effects through case reports and studies. Harmful ingredients to avoid include formaldehyde, toluene, and dibutyl phthalate.
• Polygel nails are a hybrid product of acrylic and gel that wont damage natural nails.
• Glass or crystal nail files are recommended as they last longer and are best for natural nails, as they smooth the nail tip to seal it rather than shredding the nail tip.
• When choosing a gel nail polish, it is important to choose a brand that celebrates its long-lasting formula and has many color options. Non-toxic ingredients are also important to consider.
• The EWG Skin Deep® Cosmetics Database can be used to evaluate the safety of nail products and their ingredients.

In summary, when considering nail design in 2023, it is important to choose products with non-toxic ingredients, avoid harmful chemicals, and use glass or crystal nail files. The EWG Skin Deep® Cosmetics Database can be a helpful resource for evaluating the safety of nail products and their ingredients.
