Professional-grade Circadia formulations, used exclusively by trained therapists. The science behind the products Ellen chooses — and why they work.
The ingredients Treatments using CircadiaCircadia is an American professional skincare brand rooted in the science of chrono-biology — the study of how our skin's natural circadian rhythms govern repair, renewal and resilience. Founded by the late Dr. Peter T. Pugliese, a physician and biophysicist, the brand has been built on clinical research from the outset.
Crucially, Circadia is professional-only. That means the formulations and protocols Ellen uses at The Skin Studio are not available to buy off the shelf — they are designed to be delivered by trained therapists, at concentrations and in combinations that deliver real, measurable results.
At The Skin Studio, Circadia products form the backbone of two treatments — each chosen because the formulations are genuinely suited to the skin concerns they target, not because of brand relationships or trends.
Every Circadia protocol is built around hero ingredients chosen for their clinical efficacy. These are the key ones found across both treatments.
A trio of fruit-derived enzymes that exfoliate dead skin cells, improve texture and promote cell turnover for a brighter, more luminous complexion. As skin ages, cell turnover slows — these enzymes help restore that natural rhythm.
Collagen production declines with age. Targeted peptides signal skin cells to produce more, restoring firmness and volume. L-Carnitine tightens and hydrates; L-Carnosine fights oxidative stress at a cellular level.
A rare extract that increases skin cell longevity by activating a protein linked to cellular endurance. It reinforces skin from within, building long-term resilience rather than just short-term surface effect.
A powerful detoxifying agent that draws out impurities, excess oil and environmental pollutants from deep within the pore. The Charcoal Milk Mask transforms from a cream into a hydrating milk on activation, detoxifying without stripping.
A unique two-part treatment that, once activated, creates a warm, tingling oxygen-rich foam. It floods the skin with oxygen to improve circulation, enhance nutrient delivery and heighten cellular function — leaving skin immediately calmer, tighter and more hydrated.
Spirulina is an anti-inflammatory algae that removes toxins and calms the skin. Beta Glucan is an immune-stimulating molecule that strengthens the skin barrier and locks in moisture — both helping to support long-term skin health beyond the treatment itself.
These are not treatments you can replicate at home. Here's what makes Circadia different.
Circadia's products are manufactured at concentrations and with delivery systems that simply aren't available in retail skincare. They're designed to be applied by trained hands in a controlled professional setting — which is exactly why they get results that over-the-counter products can't.
Every Circadia formula is grounded in peer-reviewed research. Dr. Pugliese's background in biophysics and medicine means the brand has never chased aesthetic fads — the focus has always been on how skin actually works at a cellular level, and how to support that biology.
Circadia protocols are frameworks, not rigid scripts. Ellen assesses your skin before every treatment and adjusts accordingly — timing, product selection and focus areas all adapt to what your skin needs that day. It's professional skincare that actually listens.
Circadia formulations are used across two of Ellen's treatments. Each protocol is chosen for what the products can actually deliver for that skin concern — not for brand loyalty.
Professional enzyme exfoliation followed by the Circadia firming peptide mask. Targets fine lines, loss of elasticity, dullness and hyperpigmentation. No downtime.
