Inner Light Bio Defense Primer is a light-adaptive blurring primer for dull, uneven skin that needs a smooth canvas and daytime defence. It blurs and brightens while helping defend against blue light.
Smoothed on after moisturiser and SPF, worn alone or under foundation.
Key benefits
A smooth, blurred canvas
Optical blurring pigments soften the look of pores and uneven texture for a smooth make-up base.
Brightens a dull complexion
Light-adaptive pigments help tired, uneven skin look more radiant.
Blue-light defence
Antioxidants help defend against blue light and environmental stress through the day.
Hydrating, not drying
A silky base that grips make-up without leaving skin tight.
What to expect
Worn under or in place of make-up, most people notice:
- A smoother, more even-looking surface
- Make-up that goes on more evenly and lasts longer
- A brighter, more radiant complexion
- A comfortable, hydrated finish
Descriptive of the typical experience with consistent use. Individual results vary.
How to use
- Apply after moisturiser and SPF
- Smooth a thin layer over the face
- Wear alone or under foundation
Loved & recommended
A good primer is as much optics as chemistry — blurring pigments diffuse light so texture softens instantly. Adding antioxidant and blue-light defence to that is a sensible modern touch. It is a nice bridge between skincare and make-up, and it wears well on dull, uneven skin.

The science behind the formula
A good primer works optically as much as chemically — blurring pigments diffuse light so pores and texture look softer. Inner Light pairs that finish with antioxidant defence for daytime wear.
The same mineral pigments that create that soft-focus finish — titanium dioxide and iron oxides — do double duty. In published dermatology research, formulas built on iron oxides and titanium dioxide attenuate a meaningful share of high-energy visible (blue) light and help protect against visible-light-induced pigmentation. That is ingredient-level evidence for the pigment class, not a measured figure for this primer — but it is why a tinted, mineral-pigment base is a genuine part of daytime “bio defence,” working alongside the antioxidants rather than relying on them alone.
FAQs
Do I wear it under or over SPF?
After moisturiser and SPF, as the last step before make-up.
Can I wear it on its own?
Yes — it gives a natural, blurred radiance without foundation.
What skin types is it for?
All skin types, especially dull or uneven-looking skin.
Does it replace my SPF?
No. Wear a dedicated sunscreen underneath — the primer is a finishing and defence step, not sun protection.
Will it work under any foundation?
Yes. Let it set for a moment, then apply foundation as usual for a smoother finish.
Is it hydrating or mattifying?
It leaves a smooth, hydrated, radiant finish rather than a flat matte one.
How much should I use?
A pea-sized amount smoothed over the face is plenty.
Is it suitable for sensitive skin?
It is formulated for all skin types. Patch test first if your skin is reactive.
How should I store it?
Keep it somewhere cool and out of direct sunlight with the cap closed, so the actives stay stable.
How is it shipped, and can I return it?
Shipping is free on every order with no minimum, and there is a 30-day, no-questions-asked return guarantee if it is not right for you.
