Circadia by Dr. Pugliese
Skincare that keeps your skin's hours.
Your skin lives on a 24 hour clock: it defends by day and repairs by night. Circadia, founded in 2001 by cellular biologist Dr. Peter T. Pugliese, builds every treatment and formulation around that rhythm. It is professional-only skincare, prescribed and performed by trained hands, and this clinic was named Circadia's Clinic of the Year in 2024.
The science
Built on how skin actually lives.
Circadia's chronobiology approach is simple to say and rare to find: work with your skin's clock, not against it.
Defend by day
Daytime formulations protect skin while it faces UV, pollution and stress, the job it is built to do in daylight.
Repair by night
At night skin shifts into renewal and regeneration, and night formulations feed exactly that work.
A scientist's brand
Founded by Dr. Peter T. Pugliese, a cellular biologist whose research shaped ingredients now standard across skincare.
Professional only
Circadia is never sold off a shelf. It reaches your skin through trained professionals who know how to use it.
Education first
The brand trains the therapists who use it, so what happens in the treatment room matches the science.
Proven here
Cronulla Skin Sanctuary was named Circadia Clinic of the Year in 2024, judged on results with exactly these treatments.
Your skin's 24 hours
One day in the life of your skin.
How a Circadia plan divides the work between the clinic, your mornings and your nights.
-
Correct
Professional Circadia treatments do the heavy lifting: correcting, strengthening and resetting your skin.
-
Defend
Your daytime prescription shields skin through UV, pollution and the day's stress.
-
Repair
Your evening prescription fuels the renewal your skin runs while you sleep.
-
Adjust
Your therapist retunes the plan as your skin, the season and your life change.
How it works
In rhythm in three steps.
Circadia rewards consistency. Here is how it folds into your skin plan.
-
01
Your skin, read first.
A consultation maps what your skin needs corrected, protected and repaired, and when.
-
02
Treated in the clinic.
Professional Circadia treatments are woven into your facials at the level your skin is ready for.
-
03
Kept in rhythm at home.
A simple day and night routine holds the results between visits, prescribed for your skin, not skin in general.
Your plan is adjusted as your skin responds, so every visit counts.
Why here
Judged on results, and named for them.
Circadia named Cronulla Skin Sanctuary its Clinic of the Year in 2024. That award is earned in the treatment room: therapists trained on the science, plans built around your skin's clock, and results the brand itself held up as the standard.
Client review
Homecare
Your results don't stop after treatment.
Professional homecare supports the work done in clinic. Your therapist prescribes what your skin actually needs, explains how to use it, and leaves out what it does not.
Good to know
Circadia, answered.
The questions people ask about circadian skincare. Anything else? The clinic is a phone call away.
What does circadian skincare actually mean?
Your skin defends itself during the day and repairs itself at night. Circadia formulates for each half of that cycle separately, so day products protect and night products fuel repair, instead of one product trying to do both badly.
Which treatments here use Circadia?
Circadia is woven through the signature facial levels, chosen by your therapist for the level your skin is at. Your consultation maps exactly where it fits your plan.
Can I buy Circadia products to use at home?
Circadia is professional-only, which is the point: your home routine is prescribed by your therapist so it matches what your skin is doing in the clinic. Ask at your consultation.
What is the Clinic of the Year award?
Circadia named Cronulla Skin Sanctuary its Clinic of the Year in 2024 in the two to three therapist category, recognising results delivered with its treatments. You can see every award on the awards page.
Is it suitable for sensitive skin?
Working with your skin's natural rhythm tends to suit reactive skin well, and nothing is applied before your therapist has read your skin. If something is not right for you yet, you will be told.
