What kind of doctor treats Forehead Lines?
A dermatologist, a doctor who treats skin conditions, is the usual specialist for forehead lines. A board-certified dermatologist can tell you whether a cosmetic treatment can give you the results you expect. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What are forehead lines?
Forehead lines are wrinkles on the forehead. A wrinkle is a crease in the skin.
Your skin changes as you age. You might notice wrinkles, age spots, and dryness. Aging skin also becomes thinner and loses fat, so it is less plump and smooth.
Many people with deep frown lines choose botulinum toxin therapy to soften them.
Symptoms
The main sign of forehead lines is the lines themselves. These skin changes can show up with age:
- Wrinkles.
- Age spots.
- Dryness.
- Thinner skin that is less plump and smooth.
Causes and who gets it
Aging changes the skin. Sunlight is a major cause of skin aging. Time outdoors without sun protection can add years to your looks.
Smoking also contributes to wrinkles. The more cigarettes a person smokes, and the more years they smoke, the more wrinkling they get.
How doctors diagnose it
A board-certified dermatologist can tell you whether a cosmetic treatment can give you the results you expect. To protect your health and get the results you seek, you should see a dermatologist. Injecting botulinum toxin may look easy, but doing it safely takes deep medical knowledge of how the body works.
Treatment
Treatment options include botulinum toxin and fillers.
Botulinum toxin, often called Botox, is one of the most popular cosmetic treatments. A dermatologist injects very small amounts of purified botulinum toxin. The shots go into targeted muscles on the face or neck. This relaxes those muscles for a while, so fine lines and wrinkles fade. The effect lasts about 3 to 4 months, and sometimes longer.
Most people return to everyday activities right away. You can have another treatment when the lines return. After the shots, take these steps so the toxin does not spread to areas where you do not want it:
- Do not rub or massage the areas that were injected.
- If you wear makeup, take care not to press or rub it in.
- Wait two hours before strenuous physical activity.
Fillers help to restore lost fullness to the face, lips, and hands. A dermatologist always offers a consultation before injecting a filler. Do-it-yourself fillers are not worth it, because the risks greatly outweigh the benefits.
Many products claim to reduce wrinkles, but the Food and Drug Administration has approved only a few for sun-damaged or aging skin.
Side effects of botulinum toxin tend to be mild and temporary. The injections, rather than the toxin itself, cause most mild side effects, such as occasional bruising. A droopy brow or eyelid for a while is rare.
Buying botulinum toxin online jeopardizes your health. Never get the shots at a non-medical spa, party, salon, or someone's home.
Cosmetic treatments can reduce the look of wrinkles, but lifestyle changes may prevent them. You can protect your skin by staying out of the sun when it is strongest, using sunscreen, wearing protective clothing, and avoiding sunlamps and tanning beds.
When to see a doctor
See a board-certified dermatologist if forehead lines bother you and you want to know whether a cosmetic treatment is right for you.
Call 911 or go to the emergency room if you have trouble breathing or cannot speak. After botulinum toxin shots, trouble breathing, swallowing, or speaking can be a sign of botulism, which is very rare.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either can look at your skin, talk through your options, and refer you to a dermatologist for cosmetic treatment.
Common questions
Are forehead lines a normal part of aging?
Yes, wrinkles are a common change in aging skin. Your skin also becomes thinner and loses fat as you age.
Can sunscreen help prevent forehead lines?
Sunscreen can help, because sunlight is a major cause of skin aging. Use sunscreen every day you are outdoors, and also wear protective clothing.
Does smoking cause forehead lines?
Smoking contributes to wrinkles. The wrinkling increases with the number of cigarettes and the number of years a person has smoked.
How long do botulinum toxin results last on the forehead?
The effect lasts about 3 to 4 months, and sometimes longer. You can have another treatment when the lines return.
Is it safe to buy botulinum toxin online?
No, buying botulinum toxin online jeopardizes your health. Products sold without proof of a medical license can differ greatly from what a dermatologist uses.
