Generally speaking, a fuller and slightly arched eyebrow shape can help create a more youthful appearance. As we age, our eyebrows tend to thin out and lose their natural arch, so adding fullness and lift can help make the face appear more lifted and youthful.
However, it's important to keep in mind that everyone's face is unique, and the ideal eyebrow shape will vary depending on factors such as face shape, bone structure, and personal preferences. It's always a good idea to consult with a professional brow stylist or esthetician to help determine the best eyebrow shape for your individual features.
