Healthy skin begins beneath the surface. Explore how the skin naturally renews itself, why visible change takes time, and the role of barrier health, Vitamin A and consistency in supporting long-term skin health.

Winter places greater demands on the skin barrier, increasing trans-epidermal water loss and leaving skin feeling dry, tight and reactive. Discover why facial oils become an essential part of a barrier-supportive routine and how corneotherapy approaches winter skin differently.

Healthy skin is not sterile skin. Explore the role of the microbiome in barrier function, inflammation and skin resilience, and learn why creating the conditions for balance is one of the most effective ways to support long-term skin health.

As we move towards Winter Solstice, the season invites us to slow down, restore and return inward. Explore the connection between winter, the nervous system and skin health, and discover a simple breathwork practice to support greater ease and resilience through the cooler months.

Understanding the natural rhythm of the skin can help you make more informed decisions about your skincare routine. Discover why your skin's needs change throughout the day and night, and how a corneotherapeutic approach can support barrier function, resilience and long-term skin health.

As Autumn sets in, the skin often becomes more reactive — with dryness, sensitivity, and flare-ups such as dermatitis and rosacea becoming more common. A barrier-first approach offers a more considered way to support the skin through seasonal change.

An exploration of how perimenopause and menopause influence the skin — from barrier function and hydration to inflammation — and why supporting the body, particularly the gut, is essential through this transition.

Many preservatives in skincare can disrupt the skin microbiome, reducing beneficial bacteria that support barrier function and resilience. This article explores a corneotherapeutic approach to preservation — one that supports balance and long-term skin health.

A compromised skin barrier can show up as dryness, sensitivity, redness and ongoing reactivity. This journal explores how to support barrier repair through a corneotherapeutic lens, with guidance on gentle cleansing, lipid replenishment, hydration and daily protection.

As the seasons shift, so too does the skin. Cooler air and lower humidity can place greater demand on the skin barrier, making autumn the ideal time to replenish essential lipids and support long-term resilience. 

The skin and nervous system are deeply interconnected. From a corneotherapeutic perspective, stress and nervous system dysregulation can influence inflammation, barrier function and skin reactivity. Supporting the skin often begins with creating internal conditions that allow the nervous system — and the skin — to settle.

That tight, squeaky-clean feeling after cleansing isn’t always a sign of healthy skin. Often, it signals disruption to the skin barrier and loss of essential lipids. Here’s how to cleanse effectively — removing SPF and makeup without stripping natural oils or unsettling the microbiome.

At SIHA, we choose non-toxic skincare because long-term skin health depends on barrier compatibility and non-irritating formulations. Grounded in corneotherapy, our approach supports the skin barrier with non-toxic skincare made in Australia and New Zealand — suitable for all skin types, including sensitive skin and conditions such as eczema, dermatitis, psoriasis, rosacea, acne-prone and compromised skin.

Inflammation often sits beneath many common skin concerns, including acne and rosacea. From a corneotherapeutic perspective, the skin barrier plays a central role in regulating inflammatory responses — and when it’s compromised, the skin can become more reactive, unstable and difficult to settle. Supporting the barrier helps create a calmer, more resilient environment for the skin to repair and respond more predictably over time.

Sensitive skin is often a response, not a permanent condition. This article explores how barrier disruption contributes to sensitivity and how gentle, barrier-first support — internally and topically — can help the skin regain balance and resilience.

In this Common Ground conversation, Sophie from Købn shares how building a small business has shaped her approach to self-care, ritual and intentional living — from skincare and daily rhythms to the role of texture, sustainability and creating calm, considered spaces at home.

Scrubs, cloths and aggressive exfoliation can quietly disrupt the skin barrier. This article explores how over-exfoliation impacts hydration and sensitivity — and why a gentler, barrier-first approach supports healthier skin.

An exploration of the skin barrier as the foundation of long-term skin health. We reflect on why protection, nourishment and consistency matter more than intensity — and how supporting the skin’s natural processes fosters resilience, balance and integrity over time.

Skin health is shaped not only by what we apply topically, but by how we digest, regulate inflammation and nourish the body from within. When the gut is balanced, the skin often appears calmer, clearer and more resilient. When it is under strain, this internal imbalance can surface as sensitivity, dryness or flare-ups.

As summer arrives with long, sunlit days and drying winds, your skin may start to quietly signal imbalance. Tightness, dullness, and sensitivity often reflect deeper dehydration beneath the surface. Here’s how to recognise the signs — and what your skin is really asking for.

In our first edition of Common Ground, we speak with Sian, co-founder of Pleasant State, about her evolving relationship with self-care, the influence of nature and motherhood on her daily rituals, and the values that shape her approach to conscious living. This thoughtful conversation explores the simplicity, intention, and clarity behind her routines — including the SIHA products she’s been loving.

Spring is a season of renewal, but it can also leave skin sensitive and unbalanced. At SIHA, we see this as the perfect time to replenish hydration, strengthen the barrier, and nurture the skin microbiome—your invisible shield—so skin can thrive with the season’s shift.

At SIHA, we choose to leave out additives that compromise skin health—fragrance, silicones, sulfates and more. Instead, our philosophy favours ingredients that mirror the skin’s own natural structures, strengthening the barrier and supporting long-term resilience.
