Frequently Asked Questions

Is Define suitable for retinol beginners?

Yes. Define as the first step in the retinol journey - formulated with a 2% AGP Retinol Complex that is gentler than standard retinol serums, making it appropriate for those new to Vitamin A. Its inclusion of triple AHAs and hydrating oils means it functions as a multi-tasking treatment, exfoliator, and moisturiser in one, reducing the complexity of introducing retinol for beginners.
Can I use Define every night?

Cosmedix recommends beginning with 2 to 4 nights per week and increasing gradually as your skin builds tolerance. Working up to nightly use is possible for most skin types, but it is important to introduce Define slowly and monitor your skin's response. It is a PM-only product and should not be used in the morning.
Does Define need to be followed with a moisturiser?

Cosmedix recommends following Define with a moisturiser if further hydration is needed. While Define contains nourishing oils that provide some moisturisation, layering it under a dedicated moisturiser such as Emulsion or Humidify is recommended for dry or mature skin types for optimal comfort.
