Photodynamic therapy (PDT) is a procedure that treats precancerous cells, in addition to other types of cancer cells. The medical treatment does this with the help of a photosensitizing drug and a light source that activates the applied drug, destroying cancer cells. PDT is approved to treat non-small cell lung cancer, esophageal cancer, and Barrett's esophagus. It's used to treat actinic keratosis, as well as acne, rosacea, skin cancer, sun damage, oily skin, wrinkles, warts, psoriasis, and enlarged sebaceous glands.

Since there is some overlap between acne and rosacea, some of the medications may be similar. Acne and rosacea have in common several possible treatments, including (but not limited to) oral antibiotics, topical antibiotics, sulfa-based face washes, isotretinoin, and many others. It is important to seek a physician's advice before using random over-the-counter acne medications since they can actually irritate skin that is prone to rosacea. Overall, rosacea skin tends to be more sensitive and easily irritated than that of common acne.


Think about it, if their "cure" really cured your acne, how are they going to continue profiting off of you? At best, the product will reduce your acne breakouts slightly, but definitely not completely. At worst, the product will do nothing at all or possibly make your acne worse! The key is buying your anti acne products from trusted, well reviewed companies that have helped thousands of acne sufferers. Buying over the counter is like flushing your money down the bowl -- don't do it!
If a pore gets clogged up and closes but bulges out from the skin, you're left with a whitehead. If a pore gets clogged up but stays open, the top surface can darken and you're left with a blackhead. Sometimes the wall of the pore opens, allowing sebum, bacteria, and dead skin cells to make their way under the skin — and you're left with a small, red bump called a pimple (sometimes pimples have a pus-filled top from the body's reaction to the bacterial infection).
Blackheads are, essentially, open comedones. "Comedone refers to plugging of the follicular opening," explains NYC dermatologist Elizabeth Hale, M.D., referring to hair follicles that technically cover your entire face and body (hi, peach fuzz). "Every hair follicle appears in a sebaceous gland." So a blackhead is the mixture of dead cells, bacteria, and grime that builds up and hardens in the follicular opening—but it's open to the world, which is why blackheads are so easy (read: tempting) to push out.

Sun exposure is a well-known flare for many rosacea sufferers. Sun protection using a wide-brimmed hat (at least 6 inches) and physical sunscreens (like zinc or titanium) are generally encouraged. Because rosacea tends to occur in mostly fair-skinned adults, physicians recommend the use of an appropriate daily SPF 50 sunscreen lotion, along with overall sun avoidance.
Sure, we’ve all heard that toothpaste or rubbing alcohol can help dry out a zit, but many DIY treatments aren't solutions for how to treat acne. In fact, applying toothpaste or rubbing alcohol are more likely to cause irritation and dryness than treat the actual pimple. Instead, stick with topical over-the-counter and prescription spot treatments with salicylic acid or benzoyl peroxide that are specially made to target pimples, says Dr. Hammerman. For an all-natural spot treatment, she suggests dabbing tea tree oil on the area a few times a day with a cotton ball.
Scars are varied and complex, and learning how to get rid of acne marks requires trial and error. There are a variety of ways to get rid of acne scars and each corner has a different proponent. However, before you go jumping on the bandwagon for the latest cure-all, we suggest breaking down the various treatments methods into their disparate parts.
A U.K. survey found that on average single men only change their sheets four times a year. And while we certainly hope you are swapping out your linens much more frequently, dirty pillowcases can lead to clogged pores. Nasty as is sounds, bacteria can build up on your bed and your face rubs around on it for a good eight hours a night. Well, that just can’t be good. If your skin is oily, change those sheets (or at least your pillowcases) twice a week. It might be a pain, but isn’t a clear complexion worth it?
Acne scars, on the other hand, are formed when there is damage to the skin which leads to abnormal collagen production, and usually appear raised or bumpy. "There are two types of acne scars: depressed and raised. Depressed scars may look like pits or craters, and raised scars may be firm and tender," explains Dr. Zeichner, who notes that unfortunately, these are permanent.

Since the UV rays and visible light from the sun can further darken acne marks, all the dermatologists agree it’s essential to wear sunscreen daily. “Sun protection can make a big difference in whether or not these marks remain permanent,” says Nagler, so much so that she’ll often recommend patients wait and see what their scars look like after a year of careful sun protection before opting for an expensive or invasive procedure. This CeraVe oil-free sunscreen is ideal for acne-prone skin, and also contains niacinamide, which is known to help brighten skin and fight inflammation.

There is also a role for Bellafill and other injectable fillers, including fat, for some depressed scars. Bellafill is currently the only filler that’s approved by the U.S. Food and Drug Administration to help raise depressed scars. It packs a one-two punch by adding volume, and also encouraging collagen formation beneath the surface by creating a supportive scaffold. “Bellafill and other injectables can fill in scars but these tend to be better for one scar,” adds New York City facial plastic surgeon Jennifer Levine, MD. Filler results can last up to 18 months. “If you have a cheek full of depressed scars, it’s better to resurface the face with laser, radiofrequency, or another energy-based treatment,” she adds.
Laser resurfacing. This procedure can be done in the doctor's or dermatologist's office. The laser removes the damaged top layer of skin and tightens the middle layer, leaving skin smoother. It can take anywhere from a few minutes to an hour. The doctor will try to lessen any pain by first numbing the skin with local anesthesia. It usually takes between 3 and 10 days for the skin to heal completely.
Consider cosmetic surgery. As a last resort, consult with a medical professional about surgery for large, deep lesions or scars. In this procedure, a doctor will use a punch excision to cut out the scar and replace it with stitching or a skin graft. Smaller lesions require only stitching, while large lesions may require a skin graft from another part of your body.[15]
Acne scar treatment: Energy-based skin resurfacing with a laser, radiofrequency, or an ultrasound device can help treat boxcar scars, according to Nada Elbuluk, MD, an assistant professor at the Ronald O. Perelman Department of Dermatology at New York University Langone Medical Center in New York City. “They all work by creating new collagen beneath the surface of the skin.” A series of treatments is likely needed based on the extent of scarring, she says. Chemical peels can also help but to a lesser extent. With either procedure, using a retinoid to increase cell turnover and further boost collagen can help improve results, Dr. Elbuluk adds.

Ans: Yes, dermatologist can help you to get rid of acne scars with various modern treatments like laser resurfacing, dermabrasion, fractional laser treatments, skin needling, dermal fillers, chemical peel, intralesional injections, punch excision and subscision surgery, cryosurgery, etc. in which you’re dermatologist will suggest the treatment as per the effect of acne scars effect on the skin.
Similar to the above natural acne remedies, these acne treatments can be inexpensive and worth giving a try. Best of all, these use products you probably already have in your household, like apple cider vinegar and toothpaste. Use home remedies for acne with caution if you have cystic acne, open sores, or inflammatory acne, which are best treated with medical supervision.

Chemical peels. Chemical peels can reduce the appearance of shallow acne scars and post-inflammatory hyper-pigmentation around a healed acne lesion. A chemical peel may be administered by a doctor, nurse, nurse practitioner, or spa aesthetician and involves applying a chemical to your skin to remove its outer layer, giving it a smoother, more even appearance. Depending on the strength of the acid used, you may experience redness and peeling for a few days afterward.
"Fluctuation in hormones, such as before one's menstrual cycle, is the main cause," explains dermatologist Julia Tzu, M.D., of Wall Street Dermatology. Specifically, androgens (male hormones) like testosterone. This usually rears its ugly head in the form of deep (painful) cystic acne around the chin, neck, and back, says dermatologist Rebecca Kazin, M.D., F.A.A.D., of the Washington Institute of Dermatologic Laser Surgery and the Johns Hopkins Department of Dermatology.
Rosacea is a common skin problem often called "adult acne." Faired skinned and menopausal women are more likely to have rosacea. Rosacea also seems to run in families. It causes redness in the center parts of the face and pimples. Blood vessels under the skin of the face may enlarge and show through the skin as small red lines. The skin may be swollen and feel warm.
Ablative lasers deliver an intense wavelength of light to the skin, removing thin outer layers of the skin (epidermis). In addition, collagen production is stimulated in the underlying layer (the dermis). Patients are typically numbed with local anesthetic and the ablation is done as an outpatient procedure. CO2 and erbium are the ablative lasers most often used for acne scar treatment.

Oral contraceptives: Oral contraceptives (birth control pills), which are low in estrogen to promote safety, have little effect on acne one way or the other. Some contraceptive pills have been shown to have modest effectiveness in treating acne. Those that have been U.S. FDA approved for treating acne are Estrostep, Ortho Tri-Cyclen, and Yaz. Most dermatologists work together with primary care physicians or gynecologists when recommending these medications.
