Hi, my name’s Bianca, and today we’re gonna be talking about Rationale skincare products.
Rationale is based off six collections, all designed to support different aspects of skincare health. Every product is personalised to your skin type, which is really the whole point of the brand. It’s not a case of everyone walking out with the same bottle.
Six collections, one idea
Each collection targets something different, whether that’s hydration, barrier strength, or cell turnover overnight. That’s what makes Rationale different from just grabbing a moisturiser off the shelf. A product that works brilliantly for my skin might do nothing for yours, so we take the time to talk it through with you rather than just recommending whatever’s popular that week.
My go-to products
My favourite is the #4 Cleanser. This one’s really good at reestablishing skin integrity, and I use it at nighttime. It leaves your skin feeling nice and hydrated and soft.
Another favourite of mine is the #6 Night Crème. This is a really nice moisturiser to put on at nighttime. It’s rejuvenating, and it contains Vitamin A to support cell turnover.
And another one, a genuine crowd favourite, is the #3 Tinted Serum SPF50+. It’s 50 plus, so it gives you solar and environmental protection throughout the day.
Find your own routine
Come in for a consultation at Absolute Cosmetic and we’ll match you up with the collections and products that actually suit your skin, rather than just my three favourites.
