What the product description says

“Rosemary essence extracted drop-by-drop at low temperature for 20 hours, offering firm, moisturized, and radiant skin.”

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin, hydroxyethyl urea.

When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol

Hydroxyethyl ureaKey active· HumectantEffect: HighA derivative of urea, a compound that is naturally present in skin. Attracts water to the upper layer of the skin. Can enhance penetration of other ingredients~0.95–1.45%

AdenosineKey activeEffect: MediumMight help improve cell turnover and reduce inflammation in skin. One study shows that the ingredients might be able to help reduce dynamic wrinkles (for example, in the corners of the eyes or on the forehead)~0.05–0.2%

Pentylene glycol· EmollientEffect: LowUsed to preserve products, dissolve other ingredients and create a nice product texture~2–3.1%

Butylene glycol· HumectantEffect: LowUsed to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin~1.6–2.4%

TocopherolEffect: Low, below effective dosePure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself~0.15–0.6%

Exfoliation

Not advertised by the brand · Hydroxyethyl urea

Works well

This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: hydroxyethyl urea.

Hydroxyethyl ureaKey activeEffect: HighA derivative of urea, a compound that is naturally present in skin. Attracts water to the upper layer of the skin. Can enhance penetration of other ingredients~0.95–1.45%

Anti-aging

Not advertised by the brand · Adenosine, Tocopherol

Works well

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

Product summary

"ELROEL - The First Rosemary Serum" is effective for: Moisturizing, Evens skin tone, Anti-aging, Exfoliation and Anti-blemish

Ingredient callouts

A good concentration of Niacinamide (2.00% - 3.00%). Niacinamide is a well-studied multi-tasking active. It is stable, and can work well in almost any hydrating formulation. There is solid evidence that Niacinamide can help support skin barrier, regulate oil production and reduce acne and clogged pores. It also helps to fight photodamage and improve the skin tone, reducing pigmentation marks.
Adenosine 0.10% - 0.45%. It is a compound that in involved in many biological processes inside the skin cells. According one high-quality clinical trial, topical Adenosine in low concentrations can somewhat help improve "deep wrinkles" - the wrinkles that appear with age in places where our faces are most dynamic (for example, on the forehead or in the corners of the eyes).
Humectants (hydroxyethyl urea 0.20% - 0.75%, sodium hyaluronate 1.10% - 1.70% and glycerin 3.70% - 5.60%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
