perioral dermatitis

The photo shows many small, fairly uniform white-topped bumps/pustules on the skin beside the lower lip and within the beard area, with mild redness. I cannot diagnose it from a photo, but the main possibilities include:
  • Folliculitis or shaving-related irritation: more likely when bumps center on hair follicles, especially after close shaving, trimming, friction, or oily products.
  • Perioral dermatitis: small papules or pustules around the mouth, often triggered or worsened by topical steroid creams, heavy moisturizers, cosmetics, or some toothpaste products. DermNet’s overview describes this pattern and its common triggers.
  • Less suggestive from this image, but important if symptoms change: cold sores (HSV) tend to be painful grouped fluid blisters that crust; impetigo more often forms spreading yellow or honey-colored crust.
For now
  • Do not apply steroid cream such as betamethasone, clobetasol, hydrocortisone, or mixed “antifungal-steroid” creams to this area unless a clinician specifically prescribed it.
  • Pause close shaving and avoid squeezing or picking. Use a clean electric trimmer if grooming is necessary.
  • Use a mild fragrance-free cleanser and stop new/oily face products, beard oils, or aftershaves temporarily.
  • Arrange an in-person visit with a dermatologist or primary-care clinician, particularly if it has lasted over 1-2 weeks or keeps returning. They can determine whether it is folliculitis, perioral dermatitis, or another cause and prescribe the appropriate treatment.
Seek prompt care if there is rapidly spreading redness, marked swelling, severe pain, fever, pus drainage, involvement of the eye, or painful blisters/ulcers.

perioral dermatitis

Being unchanged or recurrent for more than a year makes an acute infection such as impetigo or a typical cold sore much less likely.
In the photo, some of the tiny pale yellow-white, uniform bumps along the lip border and nearby skin could be Fordyce spots. These are visible, ectopic sebaceous glands, a common harmless normal variant. They can persist indefinitely and are not contagious or an STI. Andrews' Diseases of the Skin describes them as minute yellow-orange papules on the lips and oral mucosa (p. lines 1846-1850).
However, the bumps in the beard-bearing skin could also be a chronic follicular condition, particularly if they flare after shaving:
  • Pseudofolliculitis barbae: ingrown-hair or shaving-related bumps.
  • Folliculitis barbae: inflammation or infection of beard hair follicles.
  • Perioral dermatitis: persistent small similar-sized bumps around the mouth, often worsened by steroid creams or heavy/oily skin products. Dermatology texts describe it as an acne-like eruption with small papules and pustules around the mouth. Fitzpatrick's Dermatology, “Perioral Dermatitis,” lines 2358-2367.

What to do

  • Book a non-urgent dermatology appointment. A clinician can distinguish benign Fordyce spots from folliculitis/perioral dermatitis by close examination, possibly dermoscopy, and decide if a swab or other testing is needed.
  • Avoid squeezing, scrubbing, and unnecessary antibiotic or steroid creams.
  • If shaving worsens it, do not shave very close. Use an electric trimmer or shave in the direction of hair growth, without stretching the skin.
  • Avoid topical steroid or combination creams on the face unless a clinician prescribed them specifically.
Seek sooner assessment if a bump is enlarging, bleeding, ulcerating, becoming painful, spreading rapidly, or if there is pus, marked swelling, fever, or eye involvement.
