Four Ingredients We Reach For
Every few weeks there's another ingredient being called a miracle, a game changer or the next big thing. While some new ingredients are genuinely exciting, we've learnt that healthy skin isn't built by constantly chasing what's new. Instead, it's built through consistency, understanding your skin and choosing ingredients that are backed by both science and real world results. There are four ingredients we recommend time and time again because they address the foundations of healthy skin rather than offering a quick fix.
Retinal (Vitamin A) - our favourite ingredient
If there was one ingredient we could never remove from a skincare routine, Vitamin A would be high on the list. At The Functional Skin Studio, we primarily recommend retinal (retinaldehyde) rather than retinol. Why? Because retinal is one step closer to retinoic acid - the active form of Vitamin A that your skin uses, meaning it delivers results more efficiently while still being well tolerated when introduced correctly. Retinal supports healthy cell turnover, stimulates collagen production and helps improve skin texture, pigmentation, congestion, fine lines and overall skin health. Rather than targeting just one concern, it helps the skin function more effectively as a whole.
Like all active ingredients, Vitamin A isn't about using the strongest product possible. Introducing it too quickly can compromise the skin barrier and lead to irritation or sensitivity.
That's why we take a personalised approach, considering your skin barrier, current routine and treatment goals before recommending the right retinal product and how often to use it.
When used consistently, retinal remains one of the most researched and effective ingredients for supporting long term skin health.
Peptides - helping your skin communicate
Peptides are small chains of amino acids that act as messengers within the skin.
As we age, collagen production naturally slows. Peptides help encourage the skin to continue producing collagen and elastin, supporting firmness, elasticity and overall skin resilience.
They're also incredibly versatile. Whether your goal is healthy ageing, improving skin recovery after treatments or simply maintaining a stronger skin barrier, peptides are an ingredient we frequently incorporate because they work alongside the skin rather than overwhelming it.
You'll often find peptides in our recommendations following treatments like skin needling or whenever we're looking to support skin repair and long term collagen health.
Niacinamide - the multitasker
Few ingredients do as much as niacinamide. It's one of those ingredients we find ourselves recommending across almost every skin concern because it's both effective and well tolerated.
Niacinamide helps strengthen the skin barrier, reduce redness, regulate excess oil production, improve uneven skin tone and minimise the appearance of enlarged pores.
It also plays an important role in reducing inflammation and supporting the skin's natural protective function, making it an excellent ingredient for clients experiencing acne, rosacea, sensitivity or barrier impairment.
Ceramides - rebuilding the foundation
Imagine your skin barrier as a brick wall. Your skin cells are the bricks. Ceramides are the mortar holding everything together. When ceramide levels become depleted, whether through over-exfoliation, harsh cleansers, ageing, weather or certain skin conditions, the barrier develops tiny gaps. Water escapes more easily. Irritants enter more easily. The result is skin that feels dry, tight, sensitive and reactive. Replacing ceramides doesn't simply moisturise the skin. It helps rebuild the barrier itself, allowing the skin to retain hydration and better defend against external stressors.
For many clients, improving their barrier is the turning point that finally allows other treatments and active ingredients to work effectively.
Ingredients shouldn’t be in isolation
The truth is, there isn't one ingredient that's right for everyone. Healthy skin isn't about collecting every active ingredient you see online or layering multiple serums together because they're trending. It's about understanding what your skin needs right now. Sometimes your skin needs retinal. Sometimes it needs ceramides before it's ready for retinal.
Sometimes inflammation needs to be addressed before introducing stronger actives.
That's why every recommendation we make begins with understanding your skin first.
When we recommend home care, we're not simply choosing products, we're building a routine that supports your skin's biology, strengthens its natural function and complements any in clinic treatments you're having.
