In for my first round of micro-needling with Hayley! It was an amasing experience. Hayley is so knowledgeable and makes you feel so comfortable. Hayley ensured I was comfortable the whole way through treatment. The results were amazing. In the days after treatment my skin was shiny, tight and I really felt confident with my results. A month after treatment my skin still feels soft and definitely is more hydrated. Red and tight cheeks after my shower has definitely lessened. Would definitely recommend giving it a chance!

  • Microneedling 

    Microneedling is a highly effective skin treatment that works by creating tiny micro channels in the skin to stimulate natural collagen and elastin production. 

    This helps to improve skin texture, reduce fine lines, minimise pores, and soften the appearance of scarring. It also enhances the absorption of active ingredients, allowing your skin to get the most from targeted serums and boosters.

    Suitable for a wide range of skin concerns, microneedling is a safe, results-driven treatment that leaves your skin smoother, firmer, and more radiant over time.

  • Alumier MD Peels

    Alumier MD chemical peels are advanced, medical grade treatments designed to safely and effectively improve overall skin health. 

    By gently exfoliating the outer layers of the skin, they help to brighten dull complexions, refine texture, reduce pigmentation, and support clearer, more balanced skin. 

    Each peel is customised to suit your individual skin concerns, making it a results driven yet comfortable treatment that leaves your skin looking fresh, radiant, and revitalised.

  • IPL Treatment 

    IPL (Intense Pulsed Light) with the BTL Exilite system we use is an advanced skin treatment designed to visibly improve tone, texture, and overall skin clarity. Using targeted light energy, it helps to reduce and get rid of pigmentation, redness, acne, and signs of ageing while stimulating collagen for a smoother, more radiant complexion. 

    This safe and effective treatment is tailored to your skin type, making it an excellent choice for achieving clearer, brighter, and more youthful looking skin.

    In this imagine you can see a before and after of one of our acne clients after a course of IPL and alumier homecare! 

  • Laser hair removal 

    Laser hair removal is a safe and effective treatment designed to reduce unwanted hair while leaving the skin smooth and irritation free. 
    Using advanced technology, it targets the hair follicle to slow and prevent regrowth over time. 
    Suitable for a variety of skin types and areas of the body, this treatment offers a long term solution to shaving and waxing, helping you enjoy soft, confident skin all year round.

    Before your treatment, the area must be shaved and the Client must have dark hair.

  • Skin Boosters - under eye, face & Neck

    Skin boosters are deeply hydrating treatments designed to improve overall skin quality from within. Using targeted ingredients, they help to enhance hydration, smooth fine lines, and restore a healthy, radiant glow. Suitable for the face, under-eye area, and neck, skin boosters work to refresh and revitalise the skin, leaving it looking plumper, firmer, and beautifully luminous over time.

  • Phi Brows - semi permanent brows 

    Phi Brows is a microblading treatment designed to create beautifully shaped, natural looking eyebrows tailored to your unique facial features. 
    Using fine, hair like strokes and high-quality pigments, this technique enhances the shape, fullness, and symmetry of the brows for a soft, realistic finish. Perfect for those looking to define or restore their brows, Phi Brows delivers long lasting results that frame the face and enhance your overall look.
