What is shellac nails?
In beauty, “shellac nails” are a UV-cured hybrid gel-polish service (e.g., CND Shellac); despite the name, it does not use the food additive shellac (E904) resin used as a glaze.
How to remove shellac nail polish?

Why is lanolin bad for skin?
It isn’t inherently bad—lanolin is a strong occlusive moisturizer—but a small number of people develop contact allergy (often to wool alcohols) or find it too heavy and pore‑clogging. Highly purified/medical‑grade lanolin lowers the risk of irritation.
What is lanolin made of?
A complex mixture of waxy esters of long‑chain fatty acids and sterols (e.g., cholesterol/lanosterol), plus some free sterols and alcohols; it contains no triglycerides. It’s purified from the natural grease on sheep’s wool.
Is lanolin safe for baby?
Medical‑grade lanolin used on nipples for breastfeeding is generally considered safe for infants to ingest in trace amounts, but avoid if there’s a known wool/lanolin allergy. As a food additive (E913), permitted uses lead to very low exposure and are considered safe by regulators.
Is lanolin good for your skin?
Yes—lanolin is an effective emollient that reduces water loss and helps soothe and repair dry, chapped skin. A minority of people may experience contact dermatitis or breakouts.
Is lanolin safe?
As a food additive (E913), it’s authorized in the EU for specific uses (e.g., glazing/release) and is considered safe at permitted levels with minimal dietary exposure. Individuals with known lanolin/wool allergy should avoid skin contact.
