DIY Sustainable Skincare Built on Ecological Science

DIY Sustainable Skincare begins with understanding your ingredients — their origin, function, and environmental impact.

25+ years tracking pollution — now formulating skincare that doesn’t add to it.

I’m Kristina Marković — Environmental Protection Senior Expert and certified organic skincare formulator. This is where those two worlds finally meet: the science of what ingredients do on your skin, the honesty about where they go after, and the quiet joy of making something beautiful with your own hands – learn more about my qualifications and background.

For beginners who want to start right. For intermediates who want to understand why. For anyone who’s ever read an ingredient label and wondered.

The Philosophy Behind Every Formula

Before any recipe, there is intention.
These principles guide every blend I create.

CORE FORMULATION PRINCIPLES

  • Botanical Raw Materials – Selected with attention to origin, extraction method, and functional profile. Every ingredient has a story — and a responsibility.
  • Skin Barrier Support – Formulas designed around lipid balance and compatibility. What works with your skin, not against it.
  • Sustainable Sourcing – Ingredient choice considers cultivation, supply chains, and packaging impact. From field to formula to drain.
  • Transparent Logic – No greenwashing. No vague claims. Just clear formulation reasoning you can follow, question, and build on.

Where to start

Understand your ingredients before you blend. Every oil, butter, and botanical has a story — and a fate in the environment.

FORMULATION WITH PURPOSE

DIY skincare is structured thinking applied to natural ingredients.

Each balm, oil, or infusion reflects a balance between skin compatibility, stability, and environmental responsibility. Start with ingredient fundamentals. Move into structured formulations. Build routines that respect your skin — and the environment your botanicals come from.
