In dermatology, PDT with the photosensitizer Levulan Kerastick (20% delta-aminolevulinic acid HCl) is used for the treatment of very early, thin skin cancers called actinic keratoses (AK). The initial approval was specifically for the treatment of actinic keratosis of the face and scalp with a combination of an application of the photosensitizer followed by a timed exposure to a special blue light source. PDT is also used for acne, rosacea, skin cancer, sun damage, cosmetic skin improvement, oily skin, enlarged sebaceous glands, wrinkles, rejuvenation (anti-aging), warts, hidradenitis suppurativa, psoriasis, and many other skin conditions.
Hypo-pigmentation is characterized by the light spots that result from a lack of melanin. With this type of skin damage, melanocytes are depleted from the injured area or lose their ability to produce melanin. This occurs when healthy skin has been replaced with scar tissue. Because scar tissue has a light pink color, it’s more noticeable on people with darker skin tones.
Unfortunately, sometimes our workout routines can have a negative effect on our skin and be a cause of acne. One of the top perpetrators of gym-related skin conditions is dirty workout equipment. Whether it’s a yoga mat, weights, or handle bars on a cardio machine, shared gym equipment is filled with bacteria and dirt. When this comes into the contact with the skin and sits on the surface, it can cause skin irritation. If you don’t shower immediately after working out, the mixture of sweat, body oils, and bacteria can remain heavy on the surface of your skin, settling back into your pores and causing the onset of pimples.
Many people use beaten egg whites as a facial acne mask. The mask is applied to the face for about 15 minutes, then it is washed off and the skin is GENTLY patted dry with a soft cloth. Eggs have potent healing properties (due to the protein contained within) which makes this a great method for healing and clearing away acne. This is by no means an overnight acne cure, so don't get upset when you find out you have to use this technique for a matter of weeks before the effects begin to show.
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.
If you look in the mirror and see a pimple, don't touch it, squeeze it, or pick at it. This might be hard to do — it can be pretty tempting to try to get rid of a pimple. But when you play around with pimples, you can cause even more inflammation by popping them or opening them up. Plus, the oil from your hands can't help! More important, though, picking at pimples can leave tiny, permanent scars on your face.

So, what causes this skin disorder ruiner of first dates slash everything? Mainly the overproduction of oil; blocked hair follicles that don't allow the aforementioned oil to leave the pore, which often results in a clogged pore; and the growth of bacteria inside the hair follicles called P. acnes. However, along with the above factors and genetics, which plays a role in how your body reacts to different hormones in your body and can cause acne, there are certain patterns you could be repeating on a daily basis that can cause you to break out or can even exacerbate your already annoying issue. Here are some of the most surprising triggers — take heed, acne-prone people, so you, too, can have blemish-free, glowing skin!
Retinoids: Retin-A (tretinoin) has been in use for years, and preparations have become milder and gentler while still maintaining its effectiveness. Newer retinoids include adapalene (Differin) and tazarotene (Tazorac). These medications are especially helpful for unclogging pores. Side effects may include irritation and a mild increase in sensitivity to the sun. Adapalene 0.1% is now available without a prescription. With proper sun protection, however, they can be used even during sunny periods. The combination medication known as Epiduo gel -- which contains the retinoid, adapalene, along with the antibacterial, benzoyl peroxide -- is applied once a day.
