The UK skincare market is worth billions. Serums, retinols, acids, SPFs, jade rollers, LED masks — the average person spends hundreds of pounds a year layering products on their skin in the hope that something will finally work.
And yet for a huge number of people, the skin never quite gets there. The dullness persists. The breakouts keep coming. The under-eye darkness won't shift. The texture stays uneven. The hair keeps thinning.
Here's what the skincare industry doesn't want you to know: for many people, no amount of topical product will fix what's happening internally. Your skin is not a surface problem. It's a reflection of what's going on inside your body — your hormones, your nutrient levels, your inflammation status, your collagen production, your liver function. And the only way to see that clearly is to look inside.
What your skin is actually telling you
Your skin is your body's largest organ, and it communicates. Persistent dullness and a lack of radiance often point to poor circulation, low iron, or oxidative stress — your body's cells aren't getting what they need to function and repair. Breakouts in adults, particularly hormonal breakouts around the jaw and chin, are frequently driven by hormonal imbalances — elevated androgens, oestrogen fluctuations, or insulin resistance — rather than anything topical. Premature fine lines and loss of firmness are partly genetic, but they're significantly accelerated by vitamin C deficiency, low collagen precursors, high cortisol levels, and chronic inflammation. Dark circles and puffiness under the eyes are often linked to iron deficiency, poor sleep driven by hormonal disruption, or thyroid dysfunction. Dry, flaky, rough skin is one of the most common presentations of vitamin D and essential fatty acid deficiency. Hair thinning and brittle nails — which tell the same story as your skin — are classic signs of low ferritin, zinc deficiency, or thyroid issues.
In every one of these cases, you can spend as much as you like on skincare. Without addressing the underlying cause, you're treating the symptom and ignoring the problem.
The blood tests that reveal what your skin needs
A comprehensive skin-focused blood panel looks at the markers most directly linked to skin health, ageing, and appearance. At Boost & Glow, a full panel covering skin health includes vitamin D, which is essential for skin cell turnover, immune regulation in the skin, and reducing inflammation that drives breakouts and conditions like eczema and psoriasis. Vitamin C status, which directly supports collagen synthesis — without adequate vitamin C your body simply cannot produce collagen at the rate it needs to. Zinc, which regulates sebum production, supports wound healing, and has direct anti-inflammatory effects in acne-prone skin. Iron and ferritin, since low iron reduces oxygen delivery to skin cells, causing dullness, pallor, and the persistent tired look that no concealer can cover. Thyroid function, because both underactive and overactive thyroid significantly affect skin texture, moisture levels, and hair quality. Hormone panel including oestrogen, progesterone, testosterone, and DHEA — hormonal imbalances drive the majority of adult acne, accelerated skin ageing, and changes in skin texture and oil production. Collagen and inflammatory markers including CRP and homocysteine, which indicate systemic inflammation and oxidative stress — two of the biggest drivers of accelerated skin ageing. B12 and folate, since deficiencies in both affect cell turnover and can contribute to hyperpigmentation, uneven skin tone, and a dull complexion.
Understanding your baseline across these markers gives you something no skincare brand can offer: a precise picture of what your skin actually needs, rather than what a marketing campaign says it does.
IV therapy for skin — glutathione and vitamin C
Beyond testing, two of the most powerful skin treatments available are delivered intravenously at Boost & Glow — and they work in a way that topical products simply cannot replicate.
Glutathione is one of the most potent antioxidants produced by the human body. It neutralises free radicals that damage skin cells, inhibits melanin production to reduce hyperpigmentation and uneven skin tone, supports liver detoxification which directly affects skin clarity, and has significant anti-ageing effects at a cellular level. When taken orally, glutathione has very poor bioavailability — most of it is broken down in the digestive system before it can reach the bloodstream. Delivered intravenously, glutathione goes directly into your blood at therapeutic concentrations, reaching the skin cells that need it most. The results — brighter, more even, clearer skin — are noticeable and cumulative with regular treatment.
Vitamin C IV therapy works in a complementary way. At oral doses, vitamin C absorption is limited by the gut — you reach a ceiling of what your body can absorb no matter how much you take. Intravenous vitamin C bypasses this limitation entirely, delivering concentrations that are impossible to achieve orally. At these levels, vitamin C is a powerful driver of collagen synthesis, a potent antioxidant, and a significant anti-inflammatory — all three of which translate directly to better skin. The Glutathione & Vitamin C drip combines both in a single 45-minute session, delivering a concentrated dual antioxidant treatment that addresses brightening, collagen support, and inflammation simultaneously.
A protocol that actually works
The most effective approach to skin health from the inside out combines both elements — testing and treatment.
Start with a comprehensive blood panel to understand your baseline. Identify which deficiencies and imbalances are contributing to your specific skin concerns. Address nutritional gaps with targeted supplementation guided by your results. Then add IV glutathione and vitamin C treatments to deliver therapeutic-level antioxidant and collagen support that oral supplements simply cannot replicate.
This is not a quick fix. It's a considered, data-led approach to skin health that works because it addresses cause rather than symptom. Most clients notice changes within four to six weeks of consistent treatment — improved radiance, clearer skin tone, reduced breakouts, and a general quality to their skin that no serum has previously delivered.
At Boost & Glow
Lucy carries out all blood testing using venous draws — the same method used in hospitals and GP surgeries — at our clinic in Epping or at your home across Essex, Hertfordshire, and London. All IV treatments are administered by Lucy in the same settings, with a clinical assessment before every session.
If you've spent years trying to fix your skin from the outside and haven't got there, it might be time to look inside.
