8.2 Disorders of the Sebaceous and Sudoriferous Glands

NIC I.F. also tests disorders of the sebaceous (oil) glands and disorders of the sudoriferous (sweat) glands. These are not the same as primary-lesion vocabulary. A pustule is the lesion shape. Acne is the gland disorder that often produces papules and pustules. Rosacea is taught nationally as an inflammation (NIC I.F.4). It sits next to oil-gland talk in many textbooks because the face can look “acne-like,” but it is not acne. Cross-reference it here, then treat rosacea fully with the inflammations in the next section.

Illinois adds a depth rule. Public Act 104-0134 and 225 ILCS 410/3A-1 prohibit techniques intended to affect living layers of the skin. Extraction of open comedones is standard surface work. Milia and closed comedones that would require lancing below the stratum corneum are a caution. Older Illinois training and statute language treated removal of closed milia that may draw blood as restricted. The living-layer rule is the current governing principle: do not puncture living tissue to chase a pearl.

Sebaceous Disorders

Sebaceous glands secrete sebum. Disorders are too much oil, too little oil, trapped keratin, or inflammation of the follicle.

Furuncles (boils) and carbuncles (clusters of boils) are subcutaneous abscesses from bacteria in glands or follicles. They are infected, erupting lesions. You do not extract them. You refer.

Open versus closed comedones

An open comedone has a follicular opening. Air oxidizes the sebum plug; the surface looks dark. That darkness is not dirt. Hygienic extraction of a mature open comedone — gloved hands, a disinfected extractor, after softening — is ordinary Illinois esthetics. If the lesion is red, painful, or erupting, it is no longer “just a blackhead.” 1175.115(b)(34) applies.

A closed comedone is a white bump with the follicle opening blocked. It may ripen with superficial exfoliation (BHA, enzyme) or with gentle extraction when a true opening exists. Forcing a closed comedone as if it were open tears living tissue, drives post-inflammatory hyperpigmentation, and can create an excoriation. That is not “being thorough.” That is leaving a secondary lesion you then have to refuse.

Milia are even more closed. They are tiny keratin cysts without a pore opening. They are common on the eye area after heavy occlusives or in dehydrated skin. Because there is no opening, removal in some clinics meant a sterile lance. That is the Illinois caution. A lancet aimed below the stratum corneum is a technique intended to affect living layers. P.A. 104-0134 / 3A-1 is the current test, not a faded school-handout that said “always lance milia.” You may use surface methods that stay in dead cells. You may not treat milia as a medical incision-and-drainage. If a milium cannot be cleared without puncturing living skin, refer.

Acne grades and when to refer

NIC and school texts still grade acne. Use the grade to decide cosmetic support versus medical referral, not to write a prescription.

Refer when you see cysts, nodules, widespread inflammation, scarring in progress, or a client who needs a drug. Isotretinoin (Accutane) and prescription antibiotics are physician territory. You do not tell the client which drug to take (3A-1). You do not extract Grade III–IV inflammatory lesions “to get them ready for a wedding.” Heat, heavy massage, and waxing over inflamed acne make it worse.

Seborrheic dermatitis versus acne is a high-yield split. Acne is a follicular, comedonal, often oily T-zone story. Seborrheic dermatitis is inflammation with scale in the hairline, eyebrows, and nasolabial folds. Treating seborrheic scale as “just oil” with steam, extraction, and a clay mask misses the inflammation and violates the inflamed-skin rule. Seborrhea (oiliness without that inflammatory, itchy scale picture) is not the same diagnosis-shaped word as seborrheic dermatitis. On the exam, dermatitis means inflammation. Acne means a follicular sebaceous disorder that may include comedones.

Asteatosis is the opposite of seborrhea: too little sebum, dry flakes, tightness. The trap is calling all flakes “psoriasis” or all oil “acne.” Name the gland problem first. Dry, non-inflamed asteatosis may need emollients and gentler cleansing. Inflamed, cracking, or infected dry skin is a modify-or-stop.

Rosacea may sit beside this list in a review book because clients call it “adult acne.” It is chronic facial inflammation with redness, flushing, and often telangiectasia. It is not a comedone disease. Do not extract “rosacea pimples” as acne. Full teaching is in the next section (NIC I.F.4).

Sudoriferous Disorders

Sudoriferous glands are sweat glands. Four NIC names:

Miliaria rubra is the sweat-gland disorder that looks like a facial emergency. Small red vesicles and burning after heat mean you do not add steam. Vesicles plus inflammation also trigger 1175.115(b)(34). Anhidrosis is the quiet danger: a client who cannot sweat may overheat under a steamer or in a hot room. That is a refer, not a “we’ll just do a short steam.” Do not confuse anhidrosis (too little sweat) with asteatosis (too little sebum). One is a sudoriferous failure; the other is a sebaceous deficiency.

Hyperhidrosis and bromhidrosis are not contagious in the herpes sense, but they are not diseases you “cure” with a body wrap. Cosmetic hygiene still applies: clean linens, hospital-grade disinfection of surfaces, no double-dipping product. You may talk about keeping skin clean and dry as appearance and comfort. You may not prescribe a medical antiperspirant or tell the client they have a named endocrine disease.

Illinois Extraction Boundary

Put the gland science next to the license:

1. Open comedones — standard extraction when the skin is not inflamed or infected.
2. Closed comedones — only when a surface opening can be used without tearing; do not force.
3. Milia — no living-layer lancing; refer if a pearl will not yield at the stratum corneum.
4. Pustules that are frankly inflamed or erupting — no massage, no digging; 1175.115(b)(34).
5. Cysts, nodules, Grade III–IV acne, furuncles, carbuncles, steatoma — refer.
6. Seborrheic dermatitis, rosacea, miliaria rubra — inflammation, not “more extractions.”

You may explain that a product is cosmetically helpful for oily or dry appearance. You may not tell a client that a salon peel is the medical treatment for acne disease, seborrheic dermatitis, or anhidrosis. That is the 3A-1 line, applied to glands. The later extractions-and-masks chapter covers technique. This section’s exam job is to name the gland disorder and to know when Illinois law takes the extractor out of your hand.
