Hello,
This is Dr. M, OTC Specialist at OTCM.
Sun sticks continue to show steady growth within the sun care category, driven by
their
clear advantages in portability and ease of use.
In the Korean market, competition has largely centered around “matte” and
“air-light”
textures.
However, simply claiming to be lightweight or powdery is no longer enough to stand
out.
So the question becomes:
What is the next differentiation
strategy for Sun Sticks?
|
point 1
|
Transparency: The New Sun Stick Standard
|
|
In global markets with a broad skin tone spectrum, transparent sun sticks have
become a dominant format — as they do not alter the skin tone.

This naturally raises an important question:
Why are transparent Sun Sticks
still rare in Korea?
|
point 2
|
Why Transparent Sun Sticks Are Challenging
|
|
Transparent Sun Sticks are far more complex than they appear.
To succeed, they must:
|
✔ Stabilize UV filters and powders
together
|
|
✔ Maintain a solid stick structure
|
|
✔ Deliver a non-greasy, lightweight finish
|
|
✔ Be suitable for reapplication over
makeup
|
At the same time, achieving SPF50 PA++++ requires high UV filter loading and a
robust oil system.
Yet the formula must prevent powder aggregation and maintain a clean sensory profile
even within that oil system.

As these requirements stack up, most transparent sun sticks end up compromising
something:
✔ The matte finish
✔ The glide
✔ Or the transparency itself
In fact, many transparent sun sticks in the U.S. market remain below SPF50.
Higher-SPF products sometimes receive consumer feedback mentioning a “greasy” feel.
This suggests that maintaining transparency and high UV protection often comes at a
sensory trade-off.
So, can all of these conditions be satisfied at once?
And if so, how?

OTCM’s Transparent Sun Stick Solution
|
|
OTCM proposes a fully transparent Sun Stick that delivers:
✔ SPF 50 PA++++
✔ OTC compliance
✔ Sweat and water resistance
✔ A non-sticky, velvet finish
✔ Instant hydration with a subtle glow
|
✔
Perfect Transparency
with SPF50 PA++++
|
Fully transparent on application while providing strong UV protection that meets OTC
standards.
|
|
✔
Non-Sticky Velvet
Finish
|
The formula glides smoothly with minimal friction.
Upon application, it delivers a clear, healthy sheen.
After setting, OTCM’s oil-control material absorbs excess oil remaining on the skin
— up to three times its own weight — resulting in a refined velvet finish.

✔
Subtle Glow, Even Over
Makeup
|
OTCM’s Soft Glow System delivers a balanced radiance — never excessive, never dull.
It works by:
1. Evenly distributing oil across the skin surface to create directional light
reflection
2. Maintaining glide technology that does not disturb base makeup, while smoothing
skin texture
The result is a natural glow that remains intact throughout the day.

✔
Instant Hydration Upon
Application
|
Five molecular sizes of hyaluronic acid are applied strategically across different
skin layers, delivering immediate moisture upon contact.
|
|
|
✔
Long-Lasting
Performance
|
A skin-adhering protective film enhances durability against physical friction.
The formula effectively repels sweat and water, helping maintain UV protection
over time.
Is Transparency the Next Generation Sun Stick Trend?
Could transparent sun sticks become the next major format in both Korea and the
U.S.?
And then the real question begins.
If transparency becomes mainstream,
how can opaque matte Sun Sticks differentiate themselves?
