What Causes Dark Spots and Skin Tags as Skin Ages

Dark spots and small skin tags are two of the most common skin changes people notice after 40. Neither is usually a medical concern, but both tend to become more visible over time, especially on the face, neck, hands, and other areas exposed to sun or friction. This guide covers why these changes happen and what people are doing to address them.

Understanding Changes in Skin Tone and Texture

Dark spots, often called age spots or sun spots, develop when skin produces extra pigment in response to years of sun exposure. They tend to appear on areas that get the most sun over a lifetime, like the face, hands, shoulders, and chest. Skin tags are different. They're small, soft growths that often form where skin rubs against skin or clothing, such as the neck, underarms, and eyelids. Both become more common with age as skin texture and cell turnover change.

While dark spots and skin tags are generally harmless, many people choose to address them for cosmetic reasons. Sun protection, gentle exfoliation, and targeted skincare ingredients are commonly discussed as ways to help even out skin tone over time. Beyond daily skincare habits, many people also explore additional formulas designed to support brighter, more even-looking skin as part of a broader routine.

Guide Breakdown

6 Things to Know About Dark Spots and Skin Tags

These are common questions and areas of focus for people noticing changes in their skin's tone and texture.

01

What Causes Dark Spots

Dark spots form when melanin builds up in certain areas, usually from years of sun exposure. They typically appear gradually and become more noticeable with age, especially on the face and hands.

02

What Causes Skin Tags

Skin tags form where skin folds or rubs against itself or clothing. They're more common with age and in areas like the neck, underarms, and eyelids.

03

The Role of Sun Protection

Daily sun protection is one of the most commonly recommended habits for preventing new dark spots from forming and keeping existing ones from getting darker.

04

Skincare Ingredients Worth Knowing

Ingredients like vitamin C, niacinamide, and certain plant extracts are frequently mentioned in discussions about brightening skin tone and supporting a more even complexion.
