THE ESSENCE
COMPOSITION
3% dual-weight hyaluronic acid. 4% niacinamide. 2% panthenol.
A deliberately concentrated formula built around hydration, texture, and barrier support. Each active has a purpose. Each concentration was chosen to matter.
APPLICATION
Two or three drops, morning and night. Apply to clean, slightly damp skin and press gently across the face. Allow Erosine to settle before anything heavier.
SENSATION
Lightweight. Fragrance-free. Erosine disappears into the skin without a heavy or greasy finish, leaving it hydrated, supple, and smooth to the touch.

THE COMPOSITION
2% ultra-low-molecular-weight sodium hyaluronate. 1% high-molecular-weight sodium hyaluronate. 4% niacinamide. 2% panthenol.
HYDRATION
3% DUAL-WEIGHT HYALURONIC ACID
Erosine combines two molecular weights of sodium hyaluronate rather than relying on a single form: 2% ultra-low molecular weight and 1% high molecular weight.
Molecular weight influences how hyaluronic acid behaves on and interacts with the skin. Together, the two forms create a concentrated humectant system designed to bind water and support hydrated, smoother, more supple-looking skin.
TEXTURE
4% NIACINAMIDE
Niacinamide works beyond hydration. At 4%, it helps improve the appearance of uneven texture, tone, and visible pores while supporting healthy skin-barrier function.
The concentration is deliberate: 4% topical niacinamide has been evaluated in controlled human facial studies, with visible improvements reported over repeated use.
BARRIER
2% PANTHENOL
Panthenol supports hydration, comfort, and skin-barrier function. It complements the humectant system by helping the skin retain moisture and remain comfortable through daily use.
FINISH
NO ADDED FRAGRANCE
No perfume. No masking fragrance. No heavy finish.
Erosine settles into the skin within moments.
Hydration remains. The serum disappears.
THE NAME
Erosine originates from the concept of Eros, the primordial force of creation, later embodied as the god of desire and attraction.
Erosine carries that essence into the skin: vitality, radiance, suppleness, and sensation. An object made for the body, experienced through the senses.
Eros, given form.
THE RITUAL
Morning and night. Clean skin, warm palms, a few drops.
Erosine gives something immediately—the cool slip of hydration, the comfort that follows, the feel of skin newly replenished. The longer-term benefits of the formula belong to repetition.
One application is sensation.
The ritual is what allows the formula time to work.
MORNING
Two or three drops pressed into clean, slightly damp skin. Allow Erosine to settle before moisturizer and SPF.
EVENING
Return to the same gesture after cleansing. Press into the face and neck, then follow with anything heavier once absorbed.
Twice each day. The same gesture, faithfully returned to.
THE METHOD
Cleanse with the product of your choosing. Leave the skin slightly damp rather than completely dry.
Dispense two or three drops into the palms. Add another drop if extending Erosine over the neck.
Press gently across the face and neck. Allow the serum to absorb before continuing with the rest of your routine.
MORNING + NIGHT
CONSIDERED
WHAT IS EROSINE?
A concentrated daily hydration serum formulated with 2% ultra-low-molecular-weight sodium hyaluronate, 1% high-molecular-weight sodium hyaluronate, 4% niacinamide, and 2% panthenol.
It is designed to deliver substantial hydration without requiring a heavy finish.
WHAT DOES IT DO?
Erosine is built around four things: hydration, smoothness, barrier support, and comfort.
With repeated use, the formula supports softer, more supple skin and improvements in the appearance of texture, tone, and visible pores.
WHO IS IT FOR?
Dry, oily, combination, and dehydration-prone skin.
Its lightweight format is particularly suited to skin that needs water without wanting the weight of a rich product.
WHY TWO MOLECULAR WEIGHTS?
Hyaluronic acid does not behave identically at every molecular size.
Erosine combines ultra-low- and high-molecular-weight sodium hyaluronate to create a broader humectant system rather than relying on a single molecular weight.
WHY 4% NIACINAMIDE?
Because the percentage is functional, not decorative.
Published human research has evaluated topical niacinamide at 4%, with improvements reported in visible skin characteristics including texture and pore appearance over repeated use.
WHY 2% PANTHENOL?
For hydration, comfort, and barrier support.
Panthenol complements the rest of the formula by supporting the skin’s moisture barrier and helping reduce the feeling of dryness.
WHEN IS IT USED?
Morning and night, after cleansing and before moisturizer, sunscreen, oils, or other heavier products.
HOW MUCH?
Two or three drops for the face. Add another if applying to the neck.
FRAGRANCE?
None added.
WHAT IS THE FINISH?
Lightweight and fast-settling. Erosine is designed to leave hydration behind rather than a heavy, greasy film.
CAN I USE IT WITH OTHER SKINCARE?
Erosine is designed to sit easily within an existing routine. Apply it after cleansing and before heavier products.
When combining multiple active treatments, follow the directions of those products and introduce new products according to your skin’s tolerance.
