Serum Frequently Asked Questions
What is a Serum?
Targeted and transformative, serums offer a concentrated delivery of active ingredients to the skin. Known for their efficacy, serums are often used to help reduce the appearance of specific skin concerns.
When should I be using Serums?
We have a suite of Serums designed specifically for use in the morning or the evening. For daily protection, we offer #1 The Serum, #2 The Serum and #3 The Tinted Serum SPF50+. For nightly repair, we offer #5 The Serum and #5 The Milk Concentrate.
What is the key difference between #1 The Serum and #2 The Serum?
#1 The Serum boasts our proprietary Complex of B-Group Vitamins to intuitively nurture skin resilience and enhance skin calmness.
#2 The Serum features our signature Skin Identical Antioxidant Complex to fortify skin against the appearance of oxidative stress while cultivating a healthy brilliance and even tone.
Depending on your skin type, concerns and goals, both Formulations can be used as part of your daily RATIONALE Ritual. We recommend seeking expert advice or taking our Skin Questionnaire before introducing new Formulations into your Ritual.
What is the difference between #5 The Serum and #5 The Milk Concentrate?
Whilst both Formulations support a youthful and acidic pH level, #5 The Serum has been formulated with our proprietary Complex of Hydroxy Acids for those with resilient skin. On the other hand, #5 The Milk Concentrate is a gentler alternative; boasting an innovative Peptide and Amino Acid Complex.
What is the difference between a Serum and a Crème?
It’s all in the delivery system. Serums typically target the deeper layers of the skin, whereas Crèmes are typically designed to treat the superficial layers of the skin.
What is the best order to apply Serums?
#1 The Serum should be applied on clean, dry skin, as the first step in your morning Ritual.
#2 The Serum should be applied after #1 The Serum and before your daytime hydrator and SPF.
#3 The Tinted Serum SPF50+ should be applied as the final step in your morning Ritual before any skin-perfecting Formulations like Beautiful Skin Superfluid.
#5 The Serum should be applied in the evening, after cleansing and before Formulations from #6 The Renewal Collection.
#5 The Milk Concentrate should be applied in the evening, after cleansing and before Formulations from #6 The Renewal Collection.
What is the difference between oil-based and water-based Serums?
Whilst oil-based Serums contain oil-soluble active ingredients, water-based Serums contain water-soluble active ingredients.
Those experiencing signs of dryness will benefit from replenishing their skin with oil-based Formulations. On the other hand, those experiencing normal or combination skin are best suited to water-based Formulations.
