Something looks different, and you cannot quite name it. Maybe your foundation settles where it never used to. At Sheperd Integrative Dermatology, we spend a lot of time helping patients read their own skin. The signs of aging skin are not random. Each one points to something specific happening underneath, and once you know what it is, the picture becomes much less mysterious.
Why do I have brown spots on my face and hands?
Those brown spots are usually sun spots, known clinically as solar lentigines. They form when pigment cells in the skin respond to ultraviolet exposure that often builds up slowly over decades. They tend to appear first on the face, chest, shoulders, and backs of the hands, since those areas get the most sun over a lifetime.
Your Skin Is Keeping a Record, and It Shows
Skin changes with age in a fairly predictable order, even though most people notice the result years after the process began. That delay is why the changes can feel sudden when they are not.
Nearly everything you see traces back to three systems:
- Your collagen and elastin supply
- How quickly your skin cells turn over
- How your pigment cells behave
The mirror shows you the outcome of those three things, never the cause. That’s why two people the same age can look so different. One has a different sun history, different genetics, and a different set of daily habits behind the glass.
Fine Lines and Crepey Texture: Collagen and Elastin Are Thinning
Fine lines and wrinkles are usually the first change people notice, and they signal thinning structural support. Collagen production begins a slow annual decline in the mid-twenties, and elastin, the protein that lets skin spring back, is not meaningfully replaced once it breaks down.
Lines also arrive in a sequence. Dynamic rhytides come first: lines created by repeated expression, like crow’s feet and forehead creases. Static rhytides follow later, meaning the lines visible even when your face is completely at rest. That shift is a reliable sign that support underneath has dropped.
Crepey texture on the cheeks, neck, and chest carries a related message. It reads as dryness, so most people reach for a heavier moisturizer, but the dermis is thinning. Hydration improves how skin feels. It does not rebuild what is thinning below.
Dullness and Rough Texture: Cell Turnover Has Slowed Down
When patients say their skin looks tired, they usually mean slowed cell turnover. Younger skin sheds and replaces surface cells briskly. Over time, that cycle stretches, so dead cells linger and scatter light instead of reflecting it evenly. The result is dullness, roughness, age spots, and makeup that will not sit smoothly.
Slower turnover affects healing too. A small breakout that once faded in a week may now leave a mark for months. This is one of the more frustrating aging skin changes because nothing looks exactly wrong. Things simply take longer to bounce back. The useful distinction: this is a texture story, not a hydration story, and knowing which one you are facing changes what actually helps.
Volume Loss and Sagging: The Change That Is Not About Skin at All
Sometimes the change you cannot name is not in your skin. Facial fat pads shift downward and lose volume, and the underlying bone subtly remodels as well. Your face changes shape before the surface does.
That is why hollowing under the eyes or flattening through the midface reads as tired long before anyone can point to a wrinkle. Laxity along the jawline combines both stories, volume lost above and elasticity lost within. It also explains why topical products, however good, have limited reach here. They are working on a layer where the change is not happening.
Intrinsic Versus Extrinsic Aging: How to Tell Which One You Are Looking At
Every one of these skin aging signs falls into one of two categories, and sorting them is the most useful thing you can do.
- Intrinsic aging is chronological and genetic—fine lines, gradual thinning, slow volume loss.
- Extrinsic aging is environmental, driven by UV, pollution, smoking, and sleep. Pigmentation, deeper lines, leathery texture. This is the half you influence.
There is a simple comparison you can do at home. Look at the skin on your inner upper arm, then at your face and neck. One area has been protected your whole life, and the other hasn’t. The difference between them estimates how much of what you see is sun rather than time.
When a Skin Change Is Worth a Provider’s Eyes, Not a Treatment Plan
Most aging changes are gradual, symmetrical, and stable. The ones worth attention behave differently, and knowing the difference is reassuring, not alarming. Make an appointment to have a spot evaluated if it:
- Is new, or changes in size, color, shape, or border
- Bleeds, itches persistently, or will not heal
- Keeps returning in the same place
Those are medical questions, not cosmetic ones. An annual skin check matters here, and at a dermatology practice, you can answer both questions in one visit.
What You Can Actually Address, and What Comes With Time
Once you know which signal you are reading, the response gets clearer. Pigment and tone concerns are typically where light-based options such as BBL photofacials come in, since broadband light targets pigmented and vascular changes.
Non-ablative resurfacing like Moxi™ is usually discussed for texture and early sun damage. In contrast, deeper texture or more significant sun damage may be addressed with HALO® laser therapy, which combines ablative and non-ablative wavelengths to prompt the skin’s own repair response.
None of this is one-size-fits-all. Suitability depends on your skin tone, your history, and the specific change being treated, and providers assess that using the Fitzpatrick skin type scale before recommending anything. Most patients need more than one session, and results vary.
