6 The Progressive Peel

The Combined Jessner, TCA, Retinoid Peel

Introduction

In our evolution of chemical peeling for all skin types we have developed the progressive peel. This is a multiple coat peel in four steps, allowing the operator to watch the skin and adjust the peel to the skin’s reaction. Some patients will require three or four coats of each progressive peel solution I, II, III and IV. Other patients will develop the end point of the rosy red hue with a white frost with several coats of progressive peel I or II. This gradual progression of the peel allows the operator to stop at a safe end point. The step-by-step process avoids alabaster white, yellow or grey frost that may occur with high concentrations of TCA (45–55%) applied in one or two coats. Historically, the suggestions of other progressive peelers still apply (Box 6.1).

This chapter will be an overview of this progressive peel. We outline the step-by-step skin rejuvenation program (Box 6.2) for the improvement of complexion problems, fine lines and/or blotchy dyspigmentations in 155 patients. This illustrates what types of patients will benefit from the progressive peel. Afterwards, you will be able to conduct your patients through this step-by-step program to a freshened complexion. Previous authors in this textbook have also discussed skin preconditioning before the peel and more penetrating peels are covered in later chapters (see Box 6.3).

Method

Patient selection

Skin Analysis

The skin analysis is the starting point for this rejuvenation process. The patient is classified by their Fitzpatrick skin type, plus, the extent of wrinkling, blotchy dyspigmention, sallow color, telangiectasia, pebbly appearance and the presence of skin lesions such as actinic keratoses. The overall score dictates the extent of skin rejuvenation required (Box 6.4). These findings correlate with the Rubin photo aging index. Rubin Level I is characterized by epidermal findings that maybe corrected with an aggressive topical skin care program alone. Rubin Level II is associated with papillary dermal findings which require a daily skin care program plus the progressive peel. Ruben Level III is with reticular dermal level changes which may require deeper rejuvenations such as laser resurfacing, dermabrasions or phenol peels. These will be covered in later chapters.

The step-by-step skin rejuvenation program (Box 6.2)

There are five steps in the rejuvenation program. Step I of the rejuvenation process must be accomplished by the patient themselves. Free-radical generators such as sun worship, cigarette smoking and excessive refined carbohydrates in their diet must be avoided. If the patient plays golf or tennis in the sun every day or continues to smoke, the program will not work. The results will not last. If the patient continues to smoke, the collagen will be destroyed faster than it can be rebuilt. The ingestion of excessive sugars speeds up the glycosylation process in the dermis and makes the collagen more susceptible to hydrolysis.

Step II is the daily skin care program using cleansing granules, alpha hydroxyl acid toners and vitamin A conditioning lotions to accelerate the production of new skin cells. These three skin care formulations are used daily. However, patients with dry skin or who live in a dry climate start slowly, skipping days as needed to avoid retinoid dermatitis.

Step III is glycolic acid peels combined with microdermabrasions. This abrasion keeps the skin moving so it will not accommodate to step II. This step can be repeated every 2 to 4 weeks.

Steps II and III will continue for 4 to 16 weeks depending upon the skin type (Box 6.6) For example, the skin conditioning must be longer in the darker skin types to reduce the possibility of dyschromias.

Step IV will be the application of the progressive peel. This will be adequate rejuvenation for the patients with a moderate skin aging index.

Step V, the phenol peel or equivalent may be required by some patients with a higher skin aging index. These procedures are covered in later chapters.

The progressive peel

As a continuum of the skin rejuvenation process, the progressive peel is added after the skin has adjusted or accommodated to the initial two steps of the five-step program. The acute phase of retinoid dermatitis with the excessive peeling has passed. Although the skin may still be mildly flaking it will accept the peel safely; whereas, the resting untreated skin may not peel or the dermatitic skin seen during the initial phase of topical treatment with corrective skin care products is so raw that burning may develop. This process of preconditioning has been discussed in more detail in previous chapters.

Tray Setup

A standard tray set up is important so nothing will be missed (Figure 6.1). Well-marked containers are used for the four peel solutions. Folded 3″ × 3″ cotton gauze is used to scrub in the chemical solutions. Five or six mL of each solution is poured onto the gauze which is rung out before the application begins sp the solution does not drip, cotton tipped applicators are available for small areas that require touch-ups or for around the eyes or temple areas. An eye wash solution is always on the tray to irrigate the eyes, if necessary. A bottle of water is on the tray to remind the patient to drink 4 or 5 glasses during the day to flush out any penetrating chemicals.

The Progressive Peel: Step I

We use the modified Jessner solution both to clean the face and to treat the complexion at the same time. Others will use Septisol® and acetone cleansers before the application of the Jessner solution. We do not use these additional cleansers; yet, the endpoint of the erythematous blanch remains the same. As the moistened gauze of lactic acid, salicylic acid and citric acid is applied on the hair line of the forehead the operator talks the patient through the procedure. The patient controls the fan and is told to hold it close to the face if the burning sensation becomes too intense (Figure 6.2). The application of these peels progresses from the forehead to the cheeks and, then to the center of the face and across the chin, lips, and nose. Three or four coats are applied until moderate erythema develops or the burning sensation becomes intense. The patient continues with the fan for several minutes until the burning sensation fades. To avoid salicylism the patient is well hydrated with fluids and the surface area of the peel is limited to a face, neck and décolleté. The patient drinks a glass of water between steps. (See the video presentation for the actual steps of the procedure.)

Post peel procedures

The patient is told to drink an additional four glasses of water during this initial day and to wash off the retinoid in the shower four to five hours later with a mild cleanser. No occlusive ointments are applied until three days later when the peeling begins. However, the patient can use a light moisturizing cream or sunscreen the next day. The desquamation always begins in the perioral area and progresses across the face to the hairline (Figure 6.4). At that point the peeling edge is kept moist with the application of an aloe vera, petrolatum-based recovery ointment (Recovery Ointment, Vivant Pharmaceuticals, Miami FL). The patient is allowed to cut off excessive scale and moisturize but they are told not to pull or pick off this scale as this manual debridement may damage the new skin and result in reactive hyperpigmentation. A sunscreen-based moisturizer is applied to the new skin for several days until the skin can tolerate the gradual reimplementation of the skin care program. In patients with dyschromias, the application of a bleach cream is started around post peel day 8 or 9 in an attempt to block the dyspigmentation on day 17 to 20.

This progressive peel can be repeated monthly if the patient is on an aggressive rejuvenation program or three to four times annually on a more relaxed schedule.

Results

In the 155 patients studied, the peel always begins in the perioral area on the third or fourth day and progresses out across the cheeks and onto the jaw line on the fifth to seventh day. In the patients with the more extensive areas treated the peel progresses across the chest and arms on the ninth to twelfth day and reaches the back of the hands around day fifteen. The new skin revealed a freshened complexion with an improvement of the fine lines, blotchy brown dyspigmentations and acne impactions. Their daily skin care program was gradually reimplemented to prevent a recurrence. This is especially important for dyspigmentations – as the blotchy brown color tends to recur around day eighteen to twenty, so the bleaching program is reinstituted on day seven to ten. Often, the bleaching gels are too irritating for the new skin so a hydroquinone, kojic acid and vitamin A cream formulation (2/2/2 Bleaching Cream, Vivant Pharmaceuticals, Miami, FL) is preferred.

Several cases studies will illustrate our results.

Discussion

With the addition of the progressive peel to the step-by-step skin care program it is possible to significantly accelerate the skin rejuvenation process. Over time the skin accommodates or hardens to the stimulus of buffing grains, hydroxyl acid toners and vitamin A conditioning lotions just as it does to UV light or detergents. When the top layers of skin are stripped off with the Progressive Peel the daily skin care products become effective again. Also, new fibroblasts are formed and new collagen develops – which puff out the fine lines of aging.

The length of preconditioning before these peels varies with the complexion type. Dr Peter Aronshon always said, ‘White skin is a cake-walk’, meaning that peeling skin without color is easy – ‘white comes back white’. However, skin with color is a different matter, it can come back lighter or darker depending on the extent of the stimulus. In the darker complexioned patients preconditioning is much more important. The longer the skin is pretreated the easier it is to predict the final result after the peel. Also, during this preconditioning you can inform the patient about the complications. You can decide if they will tolerate temporary reactive hyperpigmentation and/or find out which patient maybe a management problem.

The major contraindication to these peels is the patients who are obsessive-compulsive pickers. They will try to convince you that they will cease picking after the peel, but the flaking of the skin drives them crazy and they can destroy your results in ten minutes in front of the mirror and, then, deny they did it.

As we have developed more experience with peels, we have decreased the strength of the TCA peeling solution. When the dermatologists initially began using TCA the usual strength was 40% to 45%. TCA turned out to be not as predictable as phenol. With phenol peels there is uniform penetration to a certain level; then, the action stops. This is not so with TCA. There are hot spots where the TCA will penetrate deeper for no apparent reason. These hot spots are less troublesome as the concentration is decreased. In our experience, we have gone from 45%, to 35%, to 25%, to 15%, and, now, to 7.5% TCA. We discovered during these dilutions that the results with TCA are coat dependent. Whereas, the results with alpha hydroxyl acids are time-dependent, and phenol results are cardio-dependent, TCA results are dependent on the number of layers applied. The more coats that are used the deeper the peel, so multiple coats of a 15% TCA can mimic the results of one or two coats of 30% TCA. These dilute peels take more time and more coats – which is exactly what we want – so we have more time to watch the blanch develop and we can discontinue applications at a predictable foggy-red blanch. The weaker strengths of TCA give us more time to think.

The operator must not only watch for the development of the white blanch, but, also, must watch the time for the disappearance of the blanch. The moderate level blanch should disappear in five minutes; whereas, a deeper level blanch may take ten minutes to fade. When the blanch takes 15 minutes or more to fade you know you are in trouble.

You will need to watch this patient closely as they may develop delayed wound healing and a potential for scarring with hypopigmentation or keloid formation. You can never go back, so it is better to err on the side of the light white. It is difficult to neutralize TCA to prevent this burn. Usually, by the time we see the deep white or yellow it is too late to neutralize. However, those with experience like Kim and Bill Cook can neutralize with a spray of bicarbonate solution within seconds of application. They can control the higher strengths. This takes practice.

The method of application is also important. Obagi taught us to scrub in the TCA with abrasive cotton gauze, not even using the newer, gentler synthetic gauzes. Visualize scrubbing in the Jessner to strip off all the debris and dead cells and; then, strip further with the TCA saturated gauzes and, finally, add a few coats of a retinoid on the gauze at the end. No wonder with all this scrubbing we can obtain a good result with dilute TCA. The previous dermatologists would gently apply a few coats of TCA from a distance with a five inch cotton swab without pressure. With this conservative approach there could be streaking since the acid was not always applied uniformly.

Do not forget the fan that the patient holds. This is critical to these peels. The rapid dehydration of these solutions from the air flow recrystalizes these chemicals (especially the TCA) and stops the burning sensation. This eliminates the pain. During the initial applications of the solutions the patients are told not to hold the fan too close. The air currents may cause the peeling solutions to run. Later, have the patient hold the fan up close to evaporate the vehicle. Also, the fan blows off the fumes – so the patient (and operator) is not inhaling the vapors.

After the procedure, do not occlude the peel. Occlusive dressings or ointments may cover the residual peel solutions and reactivate the crystals. The patient will notice pain again and this reactivation will deepen the burn. To avoid this complication nothing is placed on the peel sites until after washing in the shower several hours later. It is only important to apply ointments during the 3 to 5 day postpeel period when the peeling is coming across the face like a wave. Any pulling or stretching of the skin at this point may split the epidermis and create a fissure. This may leave a permanent pigment change or scar so have the patient keep the peeling edge moisturized with a petrolatum-based aloe vera gel recovery ointment. The petrolatum will hydrate the skin and the aloe vera will stimulate the wound healing and reduce the erythema.

Finally, be aware of the toxicology. One of the safe things about TCA is its lack of systemic toxicity. Also, we know about phenol toxicity but we often forget about the toxicity of salicylic acid. If too much surface area (face, arms and chest – 20% of the body’s surface area) is exposed to several coats of salicylic acid (14% in ethanol) that is left on the skin (as in the classic Jessner peel) eight to twelve hours later the patient can develop severe nausea, vomiting, dizziness and tinnitus from salicylism. Have the client drink eight glasses of water during the first day. The progressive peel combination is safer as much of the salicylic acid is removed by the application of step IV – the retinoids. It is still wise to limit the surface area exposed in a thin sensitive female, especially, if they also have a compromised liver or kidney. If necessary, complete the peel on distant areas with TCA alone.

The retinoid for progressive peel step IV can be either retinyl propionate 10%, retinol 1%, retinyl aldehyde 0.5% or retinoic acid 0.1%. They are interchangeable.

In summary, we have discussed the benefits of the modified Jessner peel in combination with TCA and retinoids. It is an old standard that deserves another look. Remember to visit a practitioner who is doing these peels to help you develop a feeling for the different levels of rejuvenation before you add these tools to your armamentarium.
