Before-and-after photos don't measure whether your skincare is working.
They measure what already happened — weeks ago, at a biological level
you can't see in a mirror.
Dr. Maria Feliva, Co-Founder & CEO of CheckGen, joins Jennifer Cookson
on Demystifying Cosmetics to break down molecular-level skin testing,
Why the industry's standard measurement tools miss what actually matters,
and what retinol is doing to your skin cells in the first 30 days.
What you will learn in this episode:
— Why before-and-after photos are the wrong standard for measuring
skincare results
— How long skincare products actually take to work on a molecular level
— What retinol does to your skin cells in the first 30 days —
and why do results plateau after that
— Why UV-damaged skin responds less to any skincare product
— How over-layering products creates the sensitive skin you didn't have
— What the industry currently accepts as clinical testing — and
why it's not enough
— Whether "anti-aging" will still exist as a category in 5 years
Dr. Maria Feliva is Co-Founder and CEO of CheckGen, a molecular skin
testing company working with skincare brands to evaluate product
efficacy at a biological level. Based in Australia, CheckGen works
with international brands.

Takeaways:
- What you see in a mirror is the output of biological changes that
started 2-3 weeks earlier — the skin response happens long before
it's visible
- Molecular changes from retinol begin within 30 days — after that
the skin acclimatises and plateaus; this cannot be measured in
before-and-after photos
- Inflammatory markers are among the first proteins to shift with an
effective product — inflammation doesn't have to be visible to be
present
- UV-damaged skin is in defence mode — it cannot use a topical product
efficiently while managing excess UV stress
- Over-layering products stresses the skin barrier and can create
sensitivity in skin that was previously not sensitive
- Customer surveys in industry testing are frequently guided — the
questions are framed in a way that reduces the chance of a negative
response
- Synergy between compounds in a formula can produce completely
different cellular responses than any single active tested in
isolation
