SenAllis Cosmetics Hyaluronic Acid Serum – 8 fl oz and 2 fl oz

Product Overview

SenAllis Cosmetics Hyaluronic Acid Serum is a water-based topical skin-care serum formulated primarily around sodium hyaluronate and glycerin, two ingredients commonly used as humectants in cosmetic products. The B084X51ZPM configuration contains an 8-fluid-ounce bottle and a smaller 2-fluid-ounce bottle, providing 10 fluid ounces of serum across the two containers.

The manufacturer describes the serum as having a relatively thick, syrup-like consistency. Its verified ingredient list is short and includes water, sodium hyaluronate, glycerin, phenoxyethanol, ethylhexylglycerin, propylene glycol, and caprylhydroxamic acid. No fragrance, phthalates, or parabens are identified in the current manufacturer formulation.

The product is intended for topical skin hydration. Sodium hyaluronate is the sodium salt of hyaluronic acid and functions as a humectant, while glycerin also helps retain moisture within cosmetic formulations and on the skin surface. The serum can be incorporated into a skin-care routine before heavier moisturizing products.

This reference page does not treat cosmetic claims about wrinkle reduction or anti-aging as established medical outcomes. Ingredient concentrations, molecular weight of the sodium hyaluronate, pH, and dermatological testing specifications are omitted because reliable values for this exact product were not publicly verified.

Ingredient Functions

Sodium Hyaluronate

Sodium hyaluronate is the sodium salt of hyaluronic acid. In cosmetics, it is primarily used as a humectant and skin-conditioning ingredient that helps retain water at the skin surface.

Glycerin

Glycerin is a widely used humectant. It attracts water and is commonly included in skin-care formulations intended to support surface hydration.

Water

Water serves as the primary solvent and carrier for the water-soluble ingredients in the formulation.

Phenoxyethanol

Phenoxyethanol is used as a cosmetic preservative. Its purpose is to help limit microbial growth and support product stability during normal storage and use.

Ethylhexylglycerin

Ethylhexylglycerin is commonly used as a preservative-supporting ingredient and skin-conditioning agent in cosmetic formulations.

Propylene Glycol

Propylene glycol is used as a humectant, solvent, and formulation aid in many topical cosmetic products.

Caprylhydroxamic Acid

Caprylhydroxamic acid is used as a chelating and preservation-supporting ingredient in cosmetic formulations.

Compatibility

Skin-Care Routines

The serum can be incorporated between cleansing and heavier moisturizing products. The exact sequence can vary according to the other products in a routine.

Damp Skin

Humectant serums are commonly applied to slightly damp skin or followed by a moisturizer. This helps provide water for humectant ingredients while a subsequent moisturizer can reduce moisture loss.

Facial Moisturizers

The serum can generally be layered beneath compatible creams and lotions. Allowing one layer to settle before applying another can reduce product mixing on the skin surface.

Sunscreen

When used in a daytime routine, the serum can be applied before sunscreen. Sunscreen should remain the final skin-care layer before makeup unless its instructions state otherwise.

Makeup

The serum may be used beneath makeup after it has settled on the skin. Compatibility can vary with individual complexion products and application methods.

The product is intended as a routine topical cosmetic serum. Individual frequency should be based on skin response and the directions printed on the current packaging.

Should it be applied to wet or dry skin?

The manufacturer specifically discusses applying the serum with moisture available from damp skin or another moisturizing product. Slightly damp skin is therefore compatible with its documented use.

Should moisturizer be used afterward?

A moisturizer can be applied after a humectant serum to provide an additional moisturizing layer and reduce water loss from the skin surface.

What should be done if the serum changes smell or appearance?

Unexpected changes in odor, color, separation, or texture can indicate product deterioration or contamination. The product should not be used if its condition appears abnormal.

What is the UPC?

An exact UPC for this package is not listed because available public barcode information could not be verified with sufficient confidence.

Does the product have an ISBN?

No. ISBN identifiers apply to books and other qualifying publications, not cosmetics.

Buying Considerations

Container Quantity

This configuration includes two different bottle sizes rather than one single 10 fl oz container. Users comparing configurations should distinguish the combined volume from the size of each individual bottle.

Serum Texture

The manufacturer identifies the formula as thicker than many conventional liquid serums. Texture preference can affect how a product feels during layering and application.

Simple Formula

The current ingredient list contains seven ingredients. People with ingredient sensitivities should still review the physical package because even short formulations can contain individual triggers.

Humectant-Based Hydration

Sodium hyaluronate and glycerin primarily function by attracting or retaining water. A separate moisturizer may be useful for users who also require emollient or occlusive ingredients.

Ingredient Concentration

The manufacturer does not provide a verified percentage of sodium hyaluronate for this exact configuration. Comparisons based on assumed percentages should therefore be avoided.

Cosmetic Claims

Statements such as anti-aging or wrinkle reduction should be distinguished from verified formula specifications. This page treats the product primarily as a hydrating cosmetic serum rather than a medical treatment.
