THE ESSENCE
PERFORMANCE
Erosine brings hydration, smoothness, barrier support, and comfort into one daily formula. Its presence is immediate in the feel of the skin; its fuller performance belongs to continued use.
APPLICATION
Morning and night, dispense a small amount with the dropper. Apply to clean, slightly damp skin in a thin, even layer and press gently across the face. Allow Erosine to settle before anything heavier.
EXPERIENCE
Light over the skin and quick to settle. Erosine leaves the face feeling supple, comfortable, and freshly hydrated, with a clean finish made to layer easily.

THE COMPOSITION
2% ultra-low-molecular-weight sodium hyaluronate. 0.5% high-molecular-weight sodium hyaluronate. 4% niacinamide. 2% panthenol.
HYDRATION
2.5% DUAL-WEIGHT HYALURONIC ACID
Erosine combines two molecular weights of sodium hyaluronate: 2% ultra-low molecular weight and 0.5% 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
Fragrance-free by formulation.
Erosine settles into the skin within moments, leaving a clean, light finish.
Hydration remains. The serum disappears.
THE FORMATS
The composition is identical in both formats.
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 APPLICATION
Select the conditions that most closely resemble your routine. Nothing entered here is stored.
Dispense a small amount with the dropper and apply a thin, even layer to clean, slightly damp skin. Follow with moisturizer as needed.
Morning: cleanse, Erosine, moisturizer, sunscreen. Evening: cleanse, Erosine, then moisturizer or anything heavier.
CONSIDERED
WHAT IS EROSINE?
A concentrated daily hydration serum formulated with 2% ultra-low-molecular-weight sodium hyaluronate, 0.5% 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?
At 4%, niacinamide supports barrier function and the appearance of texture, tone, and visible pores.
Published human research has evaluated topical niacinamide at this concentration, with visible improvements reported 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?
Dispense a small amount with the dropper, enough to form a thin, even layer over the face. Add a small amount when extending over 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.
