What it is

Already happy with this serum and ready for another pack? This S.NATURE Aqua Squalane Serum entry covers the 50ml refill. It makes the most sense after you know the formula suits your routine. First-time buyers should check what container they need rather than assume a photographed bottle or promotional extra is included.

Read the hydration base

The official 50ml notice lists glycerin, butylene glycol and betaine near the start, alongside panthenol and allantoin. Several hyaluronic acid forms are present, including sodium hyaluronate and hydrolyzed hyaluronic acid. Multiple forms do not establish a fixed hydration duration or an identical finish for every skin type. Squalane is listed, but the notice does not support presenting this as a high-concentration facial oil.

Decide whether a refill fits

Consider it when your routine needs a serum hydration step. If dryness remains after serum, a lotion or cream may still be useful. Kelp, eclipta leaf and witch hazel extracts are also in the formula, so check previous ingredient sensitivities. Handle the refill according to its own packaging and avoid mixing it with leftover product or another formula.

A buying question answered

This listing is for the 50ml refill pack, not a 50+50ml bottle-and-refill offer. The official 50ml ingredient notice gives no separate squalane concentration, so no ppm figure is assigned here.

Use and comparison choices

Follow the refill pack opening and handling instructions. Spread an appropriate amount gently over the face. Finish dry areas with lotion or cream as needed.

Compare this facial hydration step with the brand’s richer eye cream balm.

Use a small amount of the eye cream balm after serum on dry eye-area or facial skin.

Key ingredients

Glycerin
The most widely used humectant in skincare, drawing water toward the skin and holding it in the upper layers. Its interaction with the skin's own water channels has been studied for decades, and it is mild enough to appear across a very wide concentration range. At high levels it turns tacky, so formulas usually pair it with lighter humectants.
Betaine
An amino acid derivative obtained from sugar beet that draws in and holds water. It has a documented ability to soften surfactant harshness, so it also appears in cleansers. Because it feels less tacky than glycerin, formulas often use the two together.
PanthenolEWG 1
A precursor to vitamin B5 that converts to pantothenic acid once absorbed. It works in two directions at once, holding water and helping settle the skin barrier, which is why it appears in both calming skincare and hair care. Its low irritation profile makes it a regular in sensitive-skin formulas.
AllantoinEWG 1
Sourced from comfrey root or made synthetically, it softens rough surface texture while calming the skin. It is well tolerated enough for baby and sensitive-skin products, where it has a long history. Poor water solubility keeps its usable concentration fairly low.
Hyaluronic Acid
A glycosaminoglycan found in human skin and joints, notable for how much water it can draw in and hold. Cosmetics usually use the water-soluble sodium salt, though the acid form is sometimes listed directly. Molecular weight determines whether it sits on the surface or works down between corneocytes.
