General Contraindications

Contraindications are conditions that may be present on a client and are such that you would not be allowed to proceed with the treatment unless they have written confirmation from their GP that it is safe to do so. 

It is essential that you not only look for these problems, but you should have already asked your client if they were aware of any issues when you did your consultation.

It is vital that you check for contraindications - should you ignore them and proceed with treatment, you could find that the procedure makes the problem worse. If you are at all unsure, you should suggest that the client visits his/her GP to have the matter checked before you provide the treatment.

Precaution and Protocols

It is important to go over pre and after care instruction with your clients prior to treatment. This information will also be provided in a form that can be given and signed by your client. This can be found with the other client intake forms provided by AAI. Three of the most common side effects with any dermal enhancement is swelling, bruising and possibly small lumps or bead size bumps. However, with the Hyaluron Pen, these side effects are minimal to none. In any case, please go over these side effects with your client.    

Avoid Bruising

Although needle-free injections rarely cause bruising, it can happen. With a little knowledge on your part, bruising can be minimized.

Bruising after HA treatment can’t be cured or fixed, so the goal with bruising is to prevent it in the first place. Here are a few tips to provide clients on how to avoid bruising.

1- No aspirin, Aleve, or Ibuprofen 1 week prior to your appointment (Tylenol is fine)Do not take Vitamin E one week prior to injections. Multivitamins are okay. Stop alcohol two days prior to injections. No garlic two days prior to injections. Eat pineapple 2-3 times 1-2 days prior to injections. Take Arnica one day prior or morning of injections. You can find this at most drugstores and often at Whole Foods. Drink plenty of water before and after injections. Body dehydration is known to dissolve Hyaluronic Acid gels rather quickly. The more water you drink the longer the product will last in the lips as hyaluronic acid molecules expand by retaining water a 1,000x its weight. 

2- Lump or bumps in lipsDepending on thickness of the gel product and the size of lips, a somewhat common side effect of lip Hyaluronic Acid gels are small lumps or tiny bumps. These are usually small bruises underneath the gel. Sometimes the gel settles at injection site and can be smoothed out with a light lip massage after injection. Massaging lips gently will help smooth any bumps or lumps, but if bruising is present avoid the massage until bruising has diminished. Proper massage technique will be demonstrated to be used to help smooth out any product lumps or bumps. If lumps are caused from bruising it is best to leave lips alone and allow time to heal and settle on its own. Most bumps and lumps settle after 7-10 days. Another side effect from lip injections that often appear in lips that have either been injected multiple times over or simply a reaction to the HA gel is known as product bumps or cysts. These bumps typically show up weeks or sometimes months after injection of gels. In this situation the product can be removed or dissolved using a few different types of techniques. With the Hyaluron Pen, these side effects are greatly minimized so we will not be covering these techniques. 

3- SwellingSome swelling will occur. Icing and Arnica will help with swelling and bruising. 20 minutes on and 20 minutes off throughout the next few days after injection will help with this. It is also important to understand that the HA gel product, once injected, can expand an additional 10% several hours after injection once the cross-linked HA molecules begin to absorb the water in the body. Note that if swelling and expansion is not desired then it would be best to avoid consuming liquids until swelling goes down. Arnica comes in both a topical ointment and pill form and is a wonderful all-natural remedy for both bruising and swelling. Again, with the Hyaluron Pen, these side effects are greatly minimized. 

4- Note to patientsHyaluronic acid is a natural substance we produce within our body which promotes collagen. With age, our bodies produce less and less. In the case of HA gels, the life span of Hyaluronic Acid gel can last anywhere from 3-12 months depending on the person and where it is injected. With the Hyaluron Pen, we use fine line gel to achieve a more natural and soft appearance. The HA gel is injected into the epidermal and upper derma layer of skin which is why there is little to no bleeding. With the first application, typical results may only last a month to three months, at which point you might notice the fullness has depleted. The good news is that with every injection session you not only add additional hyaluronic acid building blocks, but you encourage your own collagen production, thus producing longer lasting results.

Frown Lines Injection

Frown lines appear on the forehead between or slightly above the brows, while smile lines form around the mouth area. Getting injections to reduce the appearance of these wrinkles is a common procedure. This video will show you how to properly inject using the Hyaluron Pen to help rid those fine lines, leaving clients with plump, younger looking skin.
