Nostril Piercing

The nostril piercing is, on a global and historical level, the most common piercing next to the earlobe piercing.
It is usually performed with a needle in 18ga to 14ga. These piercings can be pierced larger and dermal punched or stretched to larger gauges; large-gauge nostril piercings are becoming more common.

Medusa Piercing

The medusa piercing is sort of like an upside-down labret piercing. It's a piercing through the center of the upper lip; the philtrum, perpendicular to the tissue.
This piercing was named in the mid 1990s by Kerrick, a hairdresser and model from Toronto, Canada. The piercing was performed by Tom Brazda of Stainless Studios, although it was certainly not unheard of at that point. It just didn't have a name that had stuck.
This piercing is normally worn with a Labret Stud, although rings and other jewelry are possible. Some people stretch this piercing.

It is important to note that good placement is essential with this piercing. If the placement is not aesthetically balanced, it will accentuate any lack of symmetry in the wearer's face.

Labret Piercing

The Labret is a piercing through the lower lip.
Placement is important since a too-short bar can actually sink into the lip. In addition, on some people the jewelry can rub on the gum, causing it to recede.
When a ring is intended to be worn in this piercing it is commonly done at a slight angle to keep the ring from rubbing on the teeth.
Avoid the inferior labial artery that supplies in blood all the muscle around the mouth. That's visible with a powerful light.
Two labrets on each side of the lip are commonly refered to as "Snakebites", when captive bead rings are worn. Three Labrets is occasionally refered to as "Spider Bites."

Labret piercings usually heal in approximately 2 to 3 months.
PRODUCTS YOU CAN USE: Saline solution! Saline is the key to a quick healing – it balances piercings so you can heal faster! The easiest and most accurate way to acquire saline is in the form of SALINE SOLUTION FOR CONTACT LENSES.
HOW TO CLEAN YOUR PIERCING: Saline Soak: Heat a small amount of saline in a small clean plastic cup in the microwave. Place this solution in a position that will soak the piercing. For instance, hold the cup over your navel or nipple and lie back or use cotton balls, gauze, or a clean paper towel for hard to get piercings. Leave the warm saline solution there until it is cold, then rinse the piercing with fresh saline solution. Do this AT LEAST once per day.
Saline Rinse: Soften any “crusties” on the jewelry and the surrounding skin without turning the jewelry (soaking does a tremendous job – see above). Gently clean any lymph (crusties) away from the piercing using a clean Q-tip and additional saline without turning the jewelry. Do this a few times a day, when activity may cause the ring to turn (exercise, etc.), and anytime the jewelry feels “sticky” or uncomfortable until your piercing is healed.
NEVER move the jewelry back and forth through the piercing – it does way more harm than good.
Labret piercings require special care. Care for the external part of lip is stated above. Below is the recommended care for the oral part.
WHAT YOU WILL NEED: 1. Biotene® or sea salt (non-iodized) to rinse your mouth. 2. Ice for tongue piercings (it may help a little for lips too).
WHAT TO DO: Rinse your mouth with Biotene® or sea salt (1/4 tsp. Per cup of water) after you eat or drink, but primarily after meals, for the first 4 to 6 weeks.

If your piercing is sore and/or swollen, some Alive® (naproxen sodium) or Advil® (ibuprofen) may help – please only use over-the-counter drugs according to their instructions and with your physician’s approval. Rinse the piercing with saline to keep it balanced and help heal faster. Do not play with it! If you leave them alone, they will heal fast. Alternate sides if you have fishtail labret jewelry for at least a couple hours every day (or at night while sleeping) to prevent the inside lip tissue from “growing” to one side. Avoid hot and spicy food and hot drinks which will scald or increase swelling. Yogurt, bread, beer, and wine will not harm your tongue piercing, though the latter two may cause you to become drunk. NO KISSING OR SEXUAL CONTACT until it is completely healed. Keep in mind your piercing is an opening to your blood stream.

Jestrum PIERCING

A Jestrum is a vertical piercing through the upper lip. It is similar to a vertical labret, but through the upper lip rather than the bottom lip.

Horizontal Tongue Piercing

A horizontal tongue piercing is exactly what it sounds like — a piercing done across the tongue (from ear to ear), rather than vertically.
The procedure is standard piercing with a needle and jewelry follow-through. The piercing takes longer to do, and can be quite painful. Some areas allow the use of spray anestheia for the procedure. 
If proper jewelry is used in the proper placement for the individual, healing can take one to two months, and the swelling usually going down around the first two weeks. Healing time can be dramatically lengthened (sometimes over 5 months) with incorrect jewelry and placement.
Aftercare is similar to that of regular Tongue Piercing, and will require the relearning of such simple tasks such as easting and speaking. It is highly recommended that you take things "slow" during the healing process.  
If a horizontal tongue piercing is not done properly it will cripple the piercee's ability to speak. This is not necessarily because of damage caused by the piercing, but because the placement of jewelry inside the tongue interferes with mobility.
In addition, there are serious tooth-chipping risks due to the edgeward nature of the beads. Properly fitted jewelry (ie. the bead should sit flush with the tongue, with no bar showing) will minimize the chances of this, and flat or teflon/nylon beads may also be considered to minimize potential tooth damage.
Most piercers do not consider this a viable piercing because of the almost unavoidable side-effects.
To determine the best possible placement, observe the movement of the tongue during speech. In most people, there is a specific bend point — by avoiding a placement that will hinder this, speech damage can be minimized (but likely not eliminated).

Horizontal Eyebrow Piercing

Alternative to the classic eyebrow piercing. Due to its nature it is considered a surface piercing, so it should be done with a surface bar. Horizontal eyebrow piercings are normally placed along the upper brow ridge as shown in the picture below, but placement may vary depending on the personal preference and anatomy of the individual being pierced.

Eyebrow Piercing

Eyebrow piercings are generally vertical (or almost vertical) surface piercings through the ridge of the eyebrow.

Jewelry is usually 18ga to 12ga, rings or curved barbells.
