How to Use
Apply to freshly cleansed skin after any water-based serums.
Smooth over the face, neck and décolletage, avoiding the eye area. It can be used as your serum and lightweight hydrator, or followed with your usual moisturiser if your skin needs additional hydration and nourishment.
If you're new to Retinal or Vitamin A, introduce it gradually rather than jumping straight into nightly use.

Serums are designed to deliver concentrated active ingredients to the skin to target specific concerns. While your cleanser and moisturiser support the overall health and function of your skin, a serum can add a more targeted step to your routine.
Depending on the ingredients, serums can help address concerns such as dehydration, pigmentation, breakouts, redness, oiliness and visible signs of ageing. They can also support the skin barrier and provide antioxidant protection.
Because serums are usually lightweight and formulated with a higher concentration of specific active ingredients, they can be an effective way to personalise your skincare routine around what your skin needs.
You don't necessarily need lots of serums either. The right one or two, chosen for your skin and concerns, can make a meaningful difference as part of a consistent routine.
Think of your serum as the targeted treatment step in your skincare routine — chosen to support your specific skin goals.

Professional Australian-made skincare focused on skin health, corrective care and long-term skin function.
O COSMEDICS combines skin science with functional active ingredients to create high-performance skincare designed to address a wide range of skin concerns while supporting the health of the skin barrier.
Skin First Philosophy
O COSMEDICS follows the principles of Corneotherapy, a skin treatment philosophy centred around protecting, repairing and maintaining the skin's outermost layer — the stratum corneum.
Rather than taking an aggressive approach to skincare, the range focuses on working with the skin's natural biology and supporting healthy skin function. Active ingredients and corrective treatments can then be introduced according to what the skin needs and can tolerate.
Functional Actives
O COSMEDICS products are formulated with functional doses of active ingredients selected for their ability to support specific skin functions and concerns.
These actives are used across the range to target concerns including pigmentation, acne, congestion, dehydration, inflammation, redness, loss of firmness and visible signs of ageing.
Science & Skin Health
O COSMEDICS takes a skin-health approach that considers more than just the visible appearance of the skin.
Its formulations are designed around key factors that influence skin ageing and function, including collagen breakdown, inflammation, glycation, photo damage and oxidation.
The range also incorporates biomimetic ingredients — ingredients designed to work in harmony with the skin's natural structure and processes — alongside O COSMEDICS' V8 Peptide Complex®.
Australian Made & Woman Owned
O COSMEDICS is proudly Australian made, with its products manufactured at its Sydney-based facility.
The brand was developed in Australia with the unique skin challenges of the Australian environment and climate in mind. O COSMEDICS was founded by Australian skin and beauty therapist Maria Enna-Cocciolone.
Professional Skincare
O COSMEDICS is used by professional skin therapists and clinics in Australia and internationally.
The range includes everyday skincare as well as more targeted corrective products, allowing routines to be tailored to different skin types, concerns and stages of skin health.
The goal is simple: support healthy skin, address individual concerns and achieve visible results without losing sight of the skin's long-term health.
