When choosing peeling solutions to offer at the spa, important factors to consider include level, suitability, and formulation.

LEVEL

Peels are formulated as a gel, cream, or liquid solution in precise percentages of concentration and pH to exfoliate different levels of the epidermis and dermis. These levels include very superficial-, superficial-, medium-, or deep-depth.

Ideally, look for a brand that offers a range of peels – like the ones mentioned above – so that multiple options are available at the spa, depending on desired results. When considering level, it can also be important to examine pH levels. Keep in mind that the lower the pH level, the stronger the acid, and the quicker and deeper the peel will penetrate the skin. Additionally, look for peels that have been formulated to treat specific skin issues.

Very Superficial

These peels offer exfoliation using polishing agents, enzymes, and low concentrations of alpha hydroxy acid (five percent or below) and beta hydroxy acid (three percent or below). The most superficial layers of the stratum corneum are softened and removed during the exfoliation process.

Superficial

Superficial peels remove the epidermal cell layers to a greater degree, but are still considered light peels. They are formulated with moderate concentrations of alpha and beta hydroxy acid (10 to 30 percent). They help with: reducing the appearance of uneven, blotchy skin discoloration; decongesting clogged pores; and reducing acne.

Medium

This type of peel penetrates through the epidermis, into the upper most portion of the dermis known as the papillary dermis. These peels are created with a complex combination of high concentrations of acid (15 to 50 percent) with a low pH (2.0 to 1.0).

Deep

Deep peels, such as phenol and trichloroacetic acid (TCA), penetrate to the papillary dermis, depending on the concentration and number of
layers applied.

SUITABILITY

Another factor to consider when deciding on peels to offer at the spa is their suitability with various skin types. Some peels are best for fair to light skin types, for example, while others are suitable for all skin types. The best peels will improve skin texture while still being gentle enough to not irritate the skin.

FORMULATION

Keep ingredients in mind when it comes to product selection, as well. Choose a brand that adheres to high standards when formulating and is upfront about using only the highest-quality ingredients. Look for products that are paraben-free; do not include artificial dyes and fragrances; are free of mineral oil, sodium lauryl sulfates, phthalates, or other harmful ingredients; and are not tested on animals. The best brands are open about the ingredients used during formulation and will list them on their websites and packaging.

By considering factors such as these, professionals will be able to place confidence in the client satisfaction and results produced by the peels they choose to use in their spas.
