Rosacea is a long-term condition that mainly affects the face. Early signs include episodes of flushing across the cheeks, nose, forehead or chin and burning or stinging with water or skincare. Over time, redness may become persistent, small inflamed bumps can appear and tiny surface blood vessels may become visible. On brown or black skin, colour change can be subtle while warmth, swelling or discomfort remains prominent.
Some people develop sore, gritty or dry eyes and inflamed eyelids. Eye pain, redness, light sensitivity or blurred vision needs urgent assessment because inflammation of the cornea can threaten sight. Thickening of the skin, particularly around the nose, is less common and usually develops over years.
Triggers and treatment
Rosacea is not caused by poor hygiene and is not contagious. Its precise cause is uncertain, and it is not established that low stomach acid, “gut putrefaction” or gluten causes it. Common triggers include sunlight, hot or cold weather, stress, alcohol, hot drinks, spicy food and vigorous exercise. A diary can reveal personal triggers without imposing unnecessary restrictions.
Daily broad-spectrum sunscreen of at least SPF 30, gentle fragrance-free skincare and protection from extreme temperatures form a useful foundation. A GP may prescribe topical ivermectin, metronidazole or azelaic acid, or a course of oral antibiotics. Persistent visible vessels or redness may respond to laser or intense pulsed light treatment.
Useful supplements
Supplements should be selected for the individual rather than used automatically. Product directions and advice from an appropriately qualified professional should take precedence over general information.
| Supplement | Effects |
|---|---|
| Betaine hydrochloride | Increases gastric acidity and is intended to address suspected low stomach-acid production. |
| Plant-based digestive and pancreatic enzymes | Supplies enzymes intended to assist digestion across different parts of the digestive tract. |
| Whole-leaf aloe vera juice | Described as cooling and soothing and as supporting skin comfort and repair; diluted aloe is also used topically. |
| Comprehensive multivitamin and mineral formula with B vitamins | Provides B vitamins involved in energy metabolism, skin maintenance and normal digestive-enzyme production, with increased requirements sometimes associated with stress. |
| Zinc citrate | Supports normal skin healing, immune function and enzyme production. |
| Vitamin C | Supports collagen formation, antioxidant protection and normal stress-response function. |
| Krill oil or cold-pressed flaxseed oil | Provides omega-3 fats intended to support inflammatory balance and the moisture-retaining function of skin cells. |
| Grapeseed extract | Provides antioxidant plant compounds described as supporting skin repair. |
| High-strength multi-strain probiotic | Intended to support intestinal microbial balance, particularly during or after antibiotic treatment. |
Betaine hydrochloride can aggravate gastritis, reflux or ulcers and should not be combined casually with acid-suppressing medicines. Digestive enzymes are not a treatment for rosacea without a diagnosed insufficiency. Aloe taken orally may cause diarrhoea; fish oils and herbs can interact with medicines. Zinc in excess can cause copper deficiency.
Gluten avoidance is appropriate for coeliac disease or a reproducible intolerance, not as a routine rosacea treatment. The most reliable approach combines gentle skin care, sun protection, trigger management and prescribed treatment, with prompt attention to eye symptoms.
