Summer skincare from the inside out: glowing skin beyond SPF
The seasonal approach to topical versus oral nutrition
With summer firmly here and the sun making a return to centre stage, conversations around SPF and skin protection are inevitably on the rise. But savvy skin enthusiasts know that real glow, the kind that withstands the sunshine season, starts well before serum hits your cheeks.
It’s not just about what you put on your skin, but also what you put inside your body. Which is where the Dr Miriam A “sandwich” approach to caring for skin comes in.
Our one-of-a-kind strategy combines both aesthetic treatments and nutritional therapy with our dedicated nutritionist, layering oral and topical nutrients to ensure that your complexion is supported from within, to truly maximise the health of skin. Much like any layering technique, the nutrient sandwich begins at the base - inside the body. Your skin is one of the last organs to receive nutrients, meaning that your daily intake is crucial for feeding the dermis, the deeper layer of skin where collagen, elastin, and blood vessels reside.
So how do we approach this at Dr Miriam A? Through the combination of an inside-out plan to skin health. Starting with the very foundation, nutritional advice…
The Inside Layer: Oral Nutrition
For true skin health, we always recommend that patients start with the edible essentials. These include:
Beta-Carotene (the precursor to Vitamin A) is your summer-ready antioxidant hero, found in an Instagram-worthy palette of carrots, sweet potatoes, spinach, and mango. Not only does it enhance radiance, it reduces acne and signs of ageing.
Vitamin C, when ingested, boosts collagen production and shields the skin from free radicals triggered by UV exposure and pollution.
Vitamin D, often deficient even in sun-drenched months, is critical for skin integrity and helps manage inflammatory skin conditions such as eczema and psoriasis.
And let’s not forget Omega-3s: these fatty acids (from fish, flax, and algae oil supplements) support elasticity and moisture levels, calm inflammation, and smooth uneven texture. Curcumin, the active ingredient in turmeric, works on multiple levels, reducing redness, accelerating wound healing, and boosting the body’s antioxidant capacity. Just make sure it’s combined with piperine (black pepper) or in a liposomal form for maximum absorption.
For next-level internal defence, oral Niacinamide (Vitamin B3) and Jojoba supplements have shown promise in protecting against skin cancers and repairing UV-induced DNA damage.
Zinc also deserves a spotlight as it plays a vital role in wound healing and maintaining skin barrier integrity. Essential for a healthy immune system, it actively supports the repair of damaged or inflamed skin.
Biotin and Vitamin E round out the list, enhancing healing and maintaining moisture from the inside out, just be cautious with dosage, especially around blood tests.
And don’t overlook the skin microbiome. The skin has its own delicate ecosystem of bacteria that shapes its response to the external world. This balance can be disrupted by diet, infections, and topical products. A high-quality probiotic supplement, especially one formulated with skin-specific strains, can be particularly beneficial for inflammation-prone skin or when the barrier has been compromised.
The Outer Layer: Topical Nutrition
Once your base is in place and working hard to fuel your body with the right nutrients, it's time to seal the deal topically. This is where your epidermis, which is the outermost skin layer takes the spotlight. Unlike deeper layers, it lacks blood vessels and so must be fed directly via topical nutrition.
Dependent on your skin type and requirements, suggestions may include:
Vitamin A is the exfoliating powerhouse that improves texture, regulates oil, and regenerates collagen.
Vitamin C works in tandem, offering UV protection, fading pigmentation, and firming skin.
For calm, resilient skin, Vitamin E steps in with its anti-inflammatory and moisturising prowess, while topical Vitamin D plays a subtle yet vital role in soothing skin prone to thickening and inflammation.
Niacinamide is a multitasking wonder: think anti-ageing, anti-inflammatory, and barrier-boosting. Jojoba oil which is chemically similar to our natural sebum helps to regulate oil production and enhances the absorption of other actives. And if you’re not already a curcumin convert, it’s time: used topically (in carefully formulated products), it reduces redness, lightens pigmentation, and fights acne bacteria without the turmeric stains of your Top Chef moments.
The Final Layer: Sun Protection
Once your body is being fed from the inside-out, its time for the final, but most important addition, SPF. But this doesn’t need to just be applied to the skin’s surface, as Fernblock, an extract from a South American fern, offers internal UV protection, evens tone, and defends against photodamage. Think of it as your skin’s summer umbrella.
So, for your very best summer skin, don't just rely on topical skincare. Layer your skin with nutrients from the inside-out.

Beyond SPF: The Inside-Out Guide to Glowing Summer Skin
Why your skincare routine should start in your kitchen, not just your bathroom
It’s officially that time of year when the sun makes a grand return — and with it, a flurry of reminders to wear sunscreen. And while we’ll never argue against a good SPF (non-negotiable!), glowing, healthy skin is about more than just what you slather on top.
Here at Dr Miriam A, we believe in something called the “sandwich approach” — a layered, holistic approach to skincare that goes beyond serums and sheet masks. Think of it as skincare from the inside out: where what you eat is just as important as what you apply.
Skincare Starts from Within
If you’ve ever spent a fortune on skincare only to see minimal results, there’s a reason: your skin is one of the last places in the body to receive nutrients. That means topical products alone can only do so much. To really fuel your glow, you need to start from the inside.
So, what’s in this “nutrient sandwich”? Let’s break it down.
The Inner Layer: Nutrients That Feed Your Glow
Your summer skin prep should start at the table. Here are the standout nutrients we recommend to all our patients:
Beta-Carotene: The orange pigment in carrots, sweet potatoes, and mangoes isn’t just pretty — it’s a Vitamin A precursor that supports cell turnover, brightens skin, and helps fight acne.
Vitamin C: Collagen’s best friend. When taken orally, Vitamin C helps protect against UV damage, enhances firmness, and boosts overall radiance.
Vitamin D: Surprisingly, many of us are still deficient — even during summer. Vitamin D helps maintain the skin barrier and reduces inflammation, especially in conditions like eczema.
Omega-3 Fatty Acids: These healthy fats (from fish, flax, or algae oil) hydrate from within, reduce redness, and support smooth, supple skin.
Curcumin: The anti-inflammatory powerhouse found in turmeric. To get real skin benefits, look for curcumin combined with black pepper (piperine) or liposomal versions for better absorption.
Niacinamide (B3) & Jojoba Supplements: Research suggests these may help repair UV-induced skin damage and even reduce your risk of skin cancers.
Zinc: Zinc plays a key role in repairing damaged skin and maintaining your skin’s protective barrier. Plus, it’s a secret weapon against blemishes.
Biotin & Vitamin E: Both support skin healing and hydration — though we always advise monitoring your intake, especially before blood work.
Probiotics for Skin Health: Your skin has its own microbiome. A high-quality, skin-targeted probiotic can help manage inflammation and restore balance, especially if your skin barrier’s been compromised.
The Outer Layer: Topical Nutrition That Works With Your Body
Now that you’ve laid a solid nutritional foundation, it’s time to work on the skin’s surface. The epidermis doesn’t have its own blood supply, so it needs to be nourished topically.
Here are our go-to topical nutrients:
Vitamin A (Retinol): Great for improving texture, reducing oiliness, and stimulating collagen production.
Vitamin C: Helps fade pigmentation, protects against sun damage, and firms skin.
Vitamin E: Moisturizes, soothes, and protects — especially helpful after sun exposure.
Topical Vitamin D: Often overlooked, but amazing for calming inflammation-prone skin.
Niacinamide: If there’s one ingredient that does it all — this is it. It evens tone, soothes, strengthens the barrier, and helps with ageing.
Jojoba Oil: Mimics your skin’s natural sebum and helps other actives penetrate better.
Topical Curcumin: Yes, even turmeric can be used on skin — just in carefully formulated products that fight redness and acne without staining your face yellow.
The Final Layer: SPF — But Smarter
Of course, no summer skincare blog is complete without a love letter to SPF. But did you know your sun protection doesn’t have to be purely topical?
Meet Fernblock®
This botanical extract from a South American fern has been shown to offer internal UV protection. It supports even skin tone, reduces photodamage, and adds an extra layer of defense — like an invisible umbrella for your skin.
The Takeaway:
Great summer skin isn’t just about sunscreen and serums. It’s about building a skincare routine that starts from within — with the right nutrients, lifestyle choices, and professional support.
Whether you’re looking to soothe inflammation, even your tone, or just unlock that effortless glow, we’re here to guide you.
