4.2 Sebaceous & Sudoriferous Gland Disorders and Acne Grades
Key Takeaways
- Acne grades I–IV move from mostly comedones to papules and pustules and then to painful nodules and cysts; Grade IV is a stop-and-refer presentation, not an extraction challenge.
- Milia are small, white, closed keratin cysts; seborrhea is excess sebum; asteatosis is dry, sebum-deficient skin; a steatoma (wen) is a sebaceous cyst you do not excise.
- Sudoriferous disorders include hyperhidrosis (excess sweat), bromhidrosis (foul sweat odor), and anhidrosis (lack of sweat, a medical-referral heat-risk sign).
- Open pustules, nodular cysts, and picked, bleeding acne are not intact, healthy skin under Rule 240-4-.02(6); wax and facial machines stay off those sites.
- Georgia estheticians may cleanse and beautify intact acne-prone skin with cosmetics; they may not prescribe isotretinoin, inject cysts, or call extractions a therapy for a dermatological disease.
Glands you already mapped in anatomy, now seen as disorders
Chapter 2 taught sebaceous (oil) glands and sudoriferous (sweat) glands as histology. This section is what those glands look like when they misbehave on a live Georgia client. You still do not diagnose a disease for a medical chart. You still do not treat a dermatological condition. You do decide whether the T-zone is intact enough for a spa facial, whether a pustule sits in a wax strip’s path, and whether an underarm dripping with sweat is a comfort issue or a reason to reschedule a torso wax.
Rule 240-16-.02 lists structure and functions of the skin and glands next to conditions and disorders of the skin. PSI Domain 2.C will ask you to recognize those presentations as contraindications and adverse signs, not as a prescription pad.
Acne: comedones first, then inflammation, then cysts
Acne in esthetics language is a sebaceous-follicle presentation: retained sebum and keratin, often with Cutibacterium acnes (older texts say Propionibacterium acnes) and inflammation. Your eyes should sort open comedones (blackheads: oxidized plug at the surface), closed comedones (whiteheads: covered plug), papules, pustules, nodules, and cysts. Grades are a teaching ladder so you do not treat a cystic jawline like a single blackhead.
| Grade | What dominates the field | Intact-skin judgment | Georgia facial or wax move |
|---|---|---|---|
| I | Mostly open comedones, few closed comedones, rare small papules | Often intact if not picked | Gentle cleanse; extraction only on intact, non-inflamed comedones if your protocol allows; no wax over plugs you would have to scrape |
| II | Many closed comedones, more open comedones, occasional papules and pustules | Pustules are not “healthy” extraction targets | Skip wax over pustules; limit extraction; no rotary brush on inflamed islands |
| III | Red, inflamed field with many comedones, papules, and pustules | Widespread inflammation is a contraindication for heat, wax, and aggressive machines | Comfort cleanse only if the client wants it and skin is not weeping; otherwise reschedule and refer |
| IV | Cystic or nodular acne: deep, painful lumps, cysts, extensive inflammation, scarring risk | Not a salon extraction day | Stop invasive steps; do not lance cysts; refer to a licensed medical professional |
A papule is solid. A pustule shows pus. A nodule sits deeper and hurts when you press beside it. A cyst is a closed sac. In an Athens student-clinic facial, Grade I T-zone comedones on unbroken skin are not the same case as Grade IV mandibular cysts. The first may allow a conservative, hygienic extraction after softening. The second is a medical-referral conversation. Pretending a 9-mm jaw cyst is “just a stubborn blackhead” is how people bleed, scar, and leave your scope.
Isotretinoin and other prescription acne drugs are not esthetician tools. If a client reports a current dermatologist-directed oral acne medication, you still do not prescribe, and you tighten your contraindication questions (thinning barrier, delayed healing, dryness). When in doubt, delay wax and acids on fragile skin and ask the client to clear timing with the prescribing clinician. That is coordination, not you practicing medicine.
Milia, seborrhea, asteatosis, steatoma
Milia are tiny, pearly, firm, white keratin cysts, often around the eyes or on a dry cheek. They are not pustules. They have no “head” of pus to extract with a comedone extractor the way a ripe blackhead does. Forcing milia with a needle is a medical-type incision. Georgia estheticians are not licensed to perform dermatological surgery. You may note milia, avoid heavy occlusive product in that field if it bothers the client, and refer if the client wants removal.
Seborrhea is excess sebum: oily shine, enlarged-looking pores, sometimes oily scale on the scalp or brows (texts may pair this with seborrheic descriptions). It is a condition you factor into product choice (see Chapter 3), not a disease you treat with a prescription antifungal. If the scale is thick, yellow, and itchy with broken skin, you are back at intact-skin: stop picking, do not wax through fissures, refer.
Asteatosis is sebum deficiency: dry, flaky, tight skin that can fissure in winter. A Savannah bride who wants a full-face wax on asteatotic, cracked cheeks is asking you to pull wax off a damaged barrier. Hydrating cosmetics on intact dry skin can be in scope. Wax on fissures is not.
A steatoma (wen) is a sebaceous cyst, often on the scalp, neck, or back, ranging from small to quite large. It can be soft and movable. You do not excise it. You do not “drain it to help.” You do not wax a strip across a large, tender wen on a back-wax client in Augusta. Chart the location, skip the mound, and refer.
| Presentation | Gland | Look | Do not |
|---|---|---|---|
| Milia | Sebaceous / keratin retention | Tiny white beads, no pus | Needle them as a salon surgery |
| Seborrhea | Sebaceous excess | Oil, shine, possible oily scale | Call it a fungal diagnosis you will medicate |
| Asteatosis | Sebaceous deficit | Dry, flaky, possible cracks | Wax or peel over fissures |
| Steatoma (wen) | Sebaceous cyst | Doughy lump, often scalp or back | Excise or lance |
Sudoriferous disorders: too much, foul, or none
Hyperhidrosis is excessive sweating. An underarm or bikini wax on a soaking-wet field fails for adhesion and for hygiene. Blot, postpone if sweat keeps flooding the field, and never double-dip wax (Rule 240-4-.05). Hyperhidrosis is not a moral failing and not something you “cure” with a salon toxin. You manage the service or you reschedule.
Bromhidrosis is foul-smelling sweat from bacterial action on sweat and debris. Cleanse, do not shame the client, and still require a dry, intact field for wax. If the skin is macerated, raw, or fissured from moisture, it is not healthy intact tissue.
Anhidrosis is a lack of sweat. It is easy to under-study because the client is not dripping. Inability to sweat impairs cooling. A Columbus outdoor-worker who cannot sweat, feels overheated, and wants a long body wax in a warm room is not a “quick add-on.” Lack of perspiration with heat illness signs (confusion, nausea, extreme heat) is a medical-referral and first-aid situation, not a wax. Even without an emergency, anhidrosis is a finding you refer rather than “treat with a steamer to open pores.”
Miliaria rubra (prickly heat) is an inflammatory sweat-retention rash: small red papules, itching, burning, often in heat. The skin is not a good wax or occlusive-mask field until it is calm and intact. Cool the room, skip occlusion, refer if it is widespread or the client is ill.
Georgia room decisions
Facial, Grade I, intact: Marietta client, forehead open comedones, no pustules, no picking. After cleanse and optional steam on intact skin, you may perform hygienic extraction of surface comedones per your training, then soothe and protect. You are beautifying and cleansing, not claiming to cure acne disease.
Facial, Grade IV: Same zip code, but the mandible is a map of painful cysts and the client asks you to “get them all out before Saturday.” You decline invasive work, you do not insert a lancet into a cyst, you explain that deep lesions need a licensed medical professional, and you may offer only a non-invasive, non-extractive comfort cleanse if every contact area is intact—or you reschedule entirely when the field is not intact.
Wax, pustule in the strip path: Lip wax with a ripe pustule under the nose. Cutting the strip around the pustule is acceptable only if you never pull the remaining skin that is inflamed or open. If you cannot isolate intact skin, you do not wax. Tweezing through pus is still a break in infection control.
Wax, hyperhidrosis: Torso wax, client sweating through the drape. You do not chase sweat with more powder and a double-dipped spatula. You dry, you use a fresh disposable applicator, and you stop if the skin becomes raw.
Traps: grading cystic acne as Grade I so you can extract; confusing milia with whiteheads you can force; treating anhidrosis as “dry skin that needs steam”; draining a steatoma; waxing seborrheic fissures on the brow; telling a client their Grade III acne will be “cleared” by a series of salon extractions as dermatological therapy.
