Does Retinol Cause Purging?

Loose skin on neck

Struggling with lack of firmness and the appearance of neck wrinkles and sagging? Discover the causes and how you can use targeted creams, serums, and SPF to help improve the appearance of skin on your neck.

With most skincare routines focused mainly on the face, the health and appearance of the skin on our necks is often an afterthought or missed out of skincare regimens entirely.

Loose skin on neck, sometimes referred to as "turkey neck", is a natural and common part of the ageing process. As skin matures, it can gradually lose some of its surface suppleness and hydration, and the neck is an area that is often overlooked in everyday skincare routines.

There are a number of factors that can contribute to changes in the appearance of neck skin over time, including the effects of UV exposure, the natural redistribution of fat that occurs with age, and a gradual reduction in the skin's surface moisture levels.

While significant changes to the structure of neck skin are beyond the scope of skincare products alone, targeted creams and serums can help to improve the appearance of the skin on the neck — supporting hydration, helping skin feel more supple, and reducing the look of fine lines at the surface level. Alongside this, daily SPF application can play an important role in protecting the skin from further UV-related changes to its appearance.

In this article, we explore how to care for the skin on your neck, including how to choose creams and serums that may help to improve its surface appearance, and simple everyday habits that can support your skincare routine.
