Circadia
Skincare that work with your biology, not against it!
Circadia is a professional skincare range built on the science of chronobiology, the study of how the body's biological clock influences cellular function, repair, and renewal. The skin behaves fundamentally differently during the day, when it's in defence mode against UV and environmental damage, and at night, when it shifts into repair and regeneration mode. Circadia's formulations are designed around this cycle, delivering the right ingredients at the right time for maximum efficacy.
At DOSE, Circadia is used both in-clinic as part of our professional treatment protocols and as a prescribed home care range for clients. It is not a brand we simply stock, it is the foundation of how we treat and maintain skin at DOSE.
Why Circadia at DOSE?
Brittni selected Circadia as DOSE's core professional range for several reasons. The formulations are genuinely evidence-based, built on peer-reviewed research in skin biology and chronobiology. The ingredient quality is clinical-grade. The range is broad enough to address every skin type, concern, and Fitzpatrick classification, from sensitive and reactive to acne-prone, ageing, and pigmented skin. And critically, it performs in the treatment room as well as at home, which means your in-clinic results and your home routine are working in the same direction.
In-Clinic
Circadia professional products are used across DOSE's facial and advanced treatment protocols. Treatment-specific formulations including peels, enzyme therapies, corrective masks, chemical peels and targeted serums are selected by Brittni based on your skin assessment and treatment goal. Every product applied to your skin during a DOSE treatment is chosen with clinical intention, not convenience.
At Home
Circadia's retail range is prescribed by Brittni as part of your personalised home care plan. Products are selected to complement your in-clinic treatments, address your specific concerns, and support your skin's daily and nightly function. Common categories include:
- Cleansers adapted to skin type and barrier function
- Day moisturisers with antioxidant and UV-protective properties
- Night treatments formulated for repair and regeneration
- Targeted serums for pigmentation, ageing, acne, and sensitivity
- Enzyme and exfoliant treatments for at-home renewal
- Barrier-supporting and calming formulations for reactive skin
Circadia retail products are available to purchase at DOSE in-clinic or our online store. Brittni recommends only what your skin genuinely needs, you'll never leave with a bag full of products you won't use.
Who Is Circadia For?
Circadia suits virtually every skin type and concern. It is particularly well suited to clients who:
- Want professional-grade skincare that actually delivers results at home
- Are undergoing clinical treatments and want their home routine to support and extend those results
- Have reactive, sensitised, or barrier-compromised skin that doesn't tolerate mainstream products
- Are managing pigmentation, acne, or ageing and want targeted, evidence-based actives
- Want to understand what they're putting on their skin and why
FAQs
Can I buy Circadia without being a DOSE client? Yes! Circadia retail products are available to purchase right here on the DOSE website. That said, Brittni always recommends a skin consultation before prescribing a home care routine, even if you're not booking a treatment. If you're unable to make an appointment, we have our FREE online skin consultation you can complete so Brittni can make the correct recommendations for your needs. The right products depend entirely on your skin, generic routines deliver generic results.
Is Circadia safe for sensitive skin? Yes. Circadia has a strong range of formulations specifically developed for sensitive, reactive, and compromised skin. Brittni will select products appropriate for your barrier health and tolerance.
Is Circadia safe during pregnancy and breastfeeding? Some Circadia products are suitable during pregnancy and breastfeeding; others are not. Brittni assesses every product recommendation against current pregnancy and breastfeeding safety guidelines. Always let her know your status before starting any new skincare.
How is Circadia different from skincare I can buy at a pharmacy or department store? Professional-grade skincare like Circadia contains active ingredients at concentrations that deliver measurable clinical results, higher than what's permitted in over-the-counter retail products in most cases. The formulations are also designed to work together as a system, and to complement professional treatments. It's a meaningfully different category of product.
