Rosacea

While the exact cause of rosacea isn’t fully understood, several factors are thought to play a role:

• Genetics: Rosacea often runs in families, suggesting a genetic link.
• Immune Response: An overactive immune reaction to certain bacteria or environmental factors may contribute.
• Blood Vessel Function: Irregular blood vessel activity can lead to persistent redness and visible veins.
• Skin Mites (Demodex): People with rosacea often have higher numbers of these naturally occurring skin mites.
• Environmental and Lifestyle Triggers: Common flare-up triggers include sun exposure, spicy foods, alcohol, stress, temperature extremes, and certain skincare products.

Rosacea often begins with intermittent flushing but may gradually lead to more persistent and visible redness. As rosacea progresses, the skin can become increasingly sensitive and prone to reacting to skincare products, environmental shifts, or even diet and emotional stress. Without proper management, small visible blood vessels (telangiectasia) and acne-like bumps may develop. In some advanced cases, particularly in men, rosacea can lead to thickening of the skin on the nose, a condition known as rhinophyma.

A number of lifestyle and dietary habits can aggravate facial redness and trigger flushing episodes. These include:

• Spicy foods and alcohol, which increase blood flow to the skin
• Foods high in histamine, such as aged cheese and processed meats, which may lead to itchiness, redness, and flushing
• Temperature extremes, such as hot showers, saunas, cold winds, or ice baths
• Emotional stress and anxiety are common internal triggers for flushing

A suitable routine for rosacea and redness-prone skin should prioritise gentle, barrier-strengthening products that soothe inflammation. Key recommendations include:

1. Mild Cleanser: Use a fragrance-free, hydrating cleanser made for sensitive skin. Avoid scrubs or harsh foaming products.
2. Moisturiser: Choose lightweight, non-pore-clogging formulas enriched with:
   • Ceramides and essential fatty acids (linoleic and oleic acids) to strengthen the skin barrier
   • Glycerine to lock in moisture
   • Niacinamide and oat-based ingredients for calming and anti-inflammatory benefits
   • Avoid heavy creams that can trap heat and aggravate flushing.
3. Sun Protection: Opt for sunscreen that:
   • Combines mineral filters (like zinc oxide or titanium dioxide) with non-irritating chemical filters
   • Is fragrance-free and suitable for sensitive skin
4. Colour Correcting Creams: Tinted formulas can provide coverage for redness while offering additional sun protection.

Several advanced treatments are available to help reduce the redness, flushing, and sensitivity associated with rosacea:

1. Laser Treatments:
   These therapies target visible and deeper blood vessels to reduce persistent redness and improve skin tone. A combination of laser and light-based devices is often used over a series of sessions to achieve the best results. In addition to calming redness and flushing, vascular lasers can also improve acne-like lesions and sensitivity.
2. Botulinum Toxin for Facial Flushing and Redness (An advanced treatment option for persistent redness and rosacea)At Scars & Lasers, we offer advanced, precision-based treatments for facial redness and rosacea. For patients whose flushing or persistent redness does not respond to topical or laser therapy, botulinum toxin can provide effective relief. When injected in micro-doses just beneath the skin, botulinum toxin helps to calm overactive facial blood vessels and reduce the nerve signals that trigger warmth, flushing, and redness. This technique—sometimes called “micro-botox”—works by interrupting the cycle of vasodilation and inflammation that drives rosacea symptoms. Benefits
   • Reduces the intensity and frequency of facial flushing
   • Softens background redness and warmth
   • Improves comfort and skin sensitivity
   • Complements laser and topical rosacea treatments
   Treatment is quick, minimally invasive, and requires no downtime. Results are usually visible within two weeks and last around three to four months, with ongoing improvement through repeat sessions. This therapy is particularly suited to flushing-predominant rosacea, (especially in cases with exercise-induced flushing) heat-sensitive skin, or rebound redness following laser treatments. As this is an off-label but well-studied approach, all procedures are performed by experienced dermatologists who specialise in rosacea and vascular skin conditions.

Topical treatments formulated for rosacea can be helpful, but products aimed at controlling redness and flushing may sometimes irritate sensitive skin and cause rebound flushing. To minimise this risk:

• Choose products specifically made for skin prone to rosacea
• Introduce active ingredients slowly to help the skin adjust and reduce potential irritation

Caring for reactive skin requires a cautious approach. It's essential to:

• Introduce new products slowly and one at a time
• Be aware that temporary stinging or burning sensations can occur, especially in severe rosacea
• Understand that finding the right products may take some trial and error
