Wrinkles are creases and folds that occur when your skin loses its natural elasticity. They happen naturally as you age, but sun exposure and smoking can speed up the process.
Fine lines are shallow creases that appear on your skin and can be caused by repetitive facial expr 송도피부과 essions. They meet up with gravity and form deeper wrinkles over time.
Fine Lines
Fine lines are narrow creases close to the skin’s surface that develop as part of the natural aging process. They’re also caused by repeated facial expressions and sun damage. They are usually visible in areas that move when you smile, laugh or make other expressions.
Over time, loss of structural protein, including collagen and elastin, contributes to the development of wrinkles. This decline is accelerated by lifestyle practices such as unprotected sun exposure, smoking and eating a diet low in nutrients and high in fat.
While it’s impossible to stop your body’s natural aging process, there are things you can do to slow the progression of fine lines and wrinkles. Moisturizers and hydrating serums can minimize the appearance of fine lines by smoothing and plumping skin. Products with ingredients such as hyaluronic acid, which helps the skin hold onto water and maintain a more plump appearance, are particularly effective. 송도피부과
In addition, using sunscreen daily is essential for healthy skin. This is because sun damage not only increases the aging process, it also makes fine lines and wrinkles more prominent. Choosing a product that is labeled as broad spectrum, with both UVA and UVB protection will help to prevent premature aging of the skin. For longer-term improvement, topical treatments containing retinol can decrease the visibility of fine lines, improve skin’s texture and even out discoloration.
Dynamic Wrinkles
Unlike fine lines, dynamic wrinkles are visible when you smile, frown, or squint. These wrinkles appear on the forehead, between the eyebrows (also called eleven lines), and around the eyes (crow’s feet).
They develop over time as your facial muscles contract, stretch, and then relax again. You can’t completely avoid them, as they’re a natural part of aging, but you can slow the appearance of these lines by using a high-quality moisturizer and sunscreen and avoiding smoking or poor diet.
These dynamic wrinkles can morph into static wrinkles over time, as the skin loses its elasticity. To avoid this, you can get rid of dynamic rhytides early with dermal fillers or noninvasive laser resurfacing treatments, such as Clear + Brilliant or Fraxel Re:Pair.
Neurotoxin injections, such as Botox and Dysport, can also help. These injectables paralyze the muscles that cause these creases, so they can’t move as easily, smoothing out the area. It’s important to use a qualified plastic surgeon for these treatments, as the muscles must be injected exactly where they are at their weakest point. A recent study found that improvement patterns of dynamic wrinkles and skin quality are not parallel, showing that the two different aspects of aging need to be addressed separately. This means that you will need to come in for treatment less frequently as your wrinkles diminish over time.
Contraction Wrinkles
The creases and lines that appear when you smile or frown are called contraction wrinkles. They form when facial muscles contract and then disappear when the muscles relax.
They are more pronounced than fine lines and tend to persist for longer, but can be reversible with a variety of methods including getting enough sleep, moisturizing and sun protection. They can also be corrected with anti-wrinkle injections which target the specific muscle that causes the wrinkle and block its nerve activity allowing the face to relax and soften the appearance of the crease or line.
These wrinkles are not caused by skin laxity and can be created at any age. They are often a result of repeated facial expressions such as smiling or frowning and they can be made worse by smoking or drinking alcohol. They are also a natural part of the ageing process as the body produces less sebum, and the face dries out and loses its elasticity.
Myotubes fixed with 1% glutaraldehyde were subjected to mechanical force applied by a needle whose bending stiffness was measured separately in advance (see Supplementary Movie 2). Wrinkles formed on the substrate during and after the application of this external force; the length of these wrinkles correlated well with the magnitude of the applied mechanical force. These data suggest that it is important to view a muscle as a dynamic entity and not just as a static image, when performing a wrinkle analysis.
Age Spots
The appearance of age spots is another sign of aging that can make you look older. Age spots are flat brown or black blemishes on the skin and can be larger than freckles. They are usually caused by years of sun exposure. They can appear on the face, hands, arms, shoulders, or feet. Age spots are a type of hyperpigmentation and can also cause uneven skin tone.
UV rays from the sun speed up pigment cells that produce the natural dye known as melanin. Melanin gives the skin its color and protects it from damaging UV rays. Too much sun can cause excess melanin to clump together and produce large, dark spots. Age spots can also be a sign of cancer. It is important to have any new, dark spots checked by a doctor.
There are several treatments available for removing age spots, including chemical peels and laser treatment. Dr. Green uses both of these procedures in her private dermatology office. Her treatment plans take the scope of the area and patient’s skin tone into consideration to ensure that the procedure is safe and effective.
Cryotherapy used to be the most common way to remove age spots, but it has been replaced by more modern treatments. These newer methods use acid rather than liquid nitrogen to resurface the skin and essentially “melt” the age spots away.
