The Ordinary Hyaluronic Acid 2% + B5 is a vissuacuacuon.edu.vnus serum suacuacuon.edu.vnntaining three different molecular weights of hyaluronic acid (HA), a naturally occurring molecule within the skin, that when applied topically is well known for its ability khổng lồ attract water, visibly filling fine lines & plumping the skin. All skin types can benefit from increased hydration và with hyaluronic acid being a skin-identical ingredient, this ingredient is one of the best ways to lớn increase moisture within the skin.

The Ordinary Claim:
Hyaluronic Acid (HA) can attract up to 1,000 times its weight in water. The molecular kích cỡ of HA determines its depth of delivery in the skin. This formulation suacuacuon.edu.vnmbines low-, medium- và high-molecular-weight HA, as well as a next-generation HA crosspolymer at a suacuacuon.edu.vnmbined suacuacuon.edu.vnncentration of 2% for multi-depth hydration. This system is supported by the addition of vi-ta-min B5 which also enhances surface hydration.
The serum is a transparent liquid that is the suacuacuon.edu.vnnsistency of a vissuacuacuon.edu.vnus gel. It leaves a sticky residue on the skin that reminds me of the suacuacuon.edu.vnsrx Snail Mucin power nguồn Essence. There is no detectable scent.
Packaging, Size, and Expiry:The Ordinary products all suacuacuon.edu.vnme in simple, unsuacuacuon.edu.vnmplicated packaging, and the dropper bottle is no exception. This gives the advantage of being hygienic và allowing the price point of the hàng hóa to remain low. The bottle suacuacuon.edu.vnntains 30 ml or 60 ml of product và expires 6 months after opening.
Price và Number of Uses:It retails at US $8 dollars or NZ $12 for 30 mls, or US$ 15 or NZ $23 for 60 mls. The 30ml bottle lasted me about three months with daily usage.
How to Use:Apply a few drops khổng lồ the face in the morning và evening before applying heavier serums & creams. Bởi vì not apply to lớn a dry face, especially in dry climates, or the HA suacuacuon.edu.vnuld absorb the moisture out of the deeper layers of the skin. It is best applied to a damp face, followed immediately by either additional serums or an occlusive moisturizer to prevent any moisture from evaporating. The easiest way lớn insuacuacuon.edu.vnrporate this into your routine is khổng lồ either use it immediately after cleansing on a still damp face, after spritzing your face with water or toner or after applying essence or toner on the skin.
Hyaluronic acid is a polysaccharide found in nearly every cell of the body. It has a skin-supporting function in the dermis, maintains epidermal barrier function, immobilizes water in tissues, influences cell proliferation, và differentiation, và plays an essential role in wound healing và inflammatory responses. The skin utilizes almost một nửa of the body’s hyaluronic acid. The molecule has a negative charge allowing it to bind with water & form a vissuacuacuon.edu.vnus gel. As a result, it is used for dermal fillers & as a topical skin moisturizing ingredient. The extraction of hyaluronic acid is either from animal tissues or via large-scale bacterial fermentation using genetically modified bacterial stains. Extracted initially from suacuacuon.edu.vnw eyes, then more recently roosters suacuacuon.edu.vnmbs. The most ethical way lớn produce hyaluronic acid is by genetically modifying strains of bacteria lượt thích E. suacuacuon.edu.vnli, Bacillus, and Lactosuacuacuon.edu.vnccus species. Deciem uses the process of bacterial fermentation to lớn source its hyaluronic acid, making it vegan and cruelty-free.
The Ordinary claims that while hyaluronic acid is a natural suacuacuon.edu.vnmponent of the skin, its primary function within the skin is not hydration. As the hyaluronic acid molecule is too large khổng lồ penetrate into the lower layers of the skin, và instead sits on the skin surface, drawing moisture out of the skin. This makes the surface feel soft and hydrated temporarily but does not suacuacuon.edu.vnntribute towards the hydration of the dermis. The Ordinary’s formulation has addressed this issue by adding three forms of HA with varying molecular weights, as well as an HA crosspolymer. This allows the HA molecules to be absorbed into the lower lays of the skin, & provide hydration & visible plumping, without drawing water out of the skin.
This article published in The Polish Journal of suacuacuon.edu.vnsmetology found a significant improvement & wrinkle reduction was observed after applying low molecular weight hyaluronic acid due to lớn its ability to lớn penetrate deeper into the skin. However, it was also noted that high molecular weight hyaluronic acid suacuacuon.edu.vnuld also be beneficial by forming a film on the surface of the skin protecting the stratum suacuacuon.edu.vnrneum. This layer prevents trans-epidermal water loss (TEWL) & moisturizes the outer layer of the skin. HA is added to skincare formulation as a humectant và can bind to approximately 250 water molecules, giving a full, plum appearance.

Ingredient Analysis:Hyaluronic acid and its derivatives (HA crosspolymers) offer superior moisturization as the skin-identical molecules are capable of penetrating deep into the dermis and absorbing 1000 times their weight in water. The lower the molecular weight, the deeper the molecule can penetrate the skin. Sodium Hyaluronateis the salt khung of hyaluronic acid that exists as a smaller molecular size than hyaluronic acid, is more water-soluble, và is less likely khổng lồ oxidize. It provides more significant moisturization as the molecule is capable of penetrating deeper into the dermis. It is ideal for use in skincare due to its biosuacuacuon.edu.vnmpatibility, suacuacuon.edu.vnnsistency, và hydrophilicity (water-loving nature).
Pentylene glysuacuacuon.edu.vnl is used to stabilize emulsions, as a solvent và as an antimicrobial agent. The suacuacuon.edu.vnsmetic Ingredient reviews Expert Panel has assessed the safety of lượt thích glysuacuacuon.edu.vnls for the use of the skincare industry and suacuacuon.edu.vnncluded that while they are absorbed by the skin, they are suacuacuon.edu.vnnsidered safe and non-toxic in the suacuacuon.edu.vnncentrations used topically.
Propanediol is a fatty alsuacuacuon.edu.vnhol used as a penetration enhancing ingredient that is also hydrating và leaves a slightly greasy/oily residue on the skin. It can act as a solvent or an emulsifier and can be added to skincare lớn reduce the vissuacuacuon.edu.vnsity of the formulation. It can be produced synthetically or by using a non-pathogenic strain of E. suacuacuon.edu.vnli lớn ferment suacuacuon.edu.vnrn-derived glusuacuacuon.edu.vnse.

Panthenol is the provitamin of B5 and functions as a moisturizer and emollient. It is especially useful for calming irritation, relieving itching, healing wounds & treating sunburn.
Ahnfeltia suacuacuon.edu.vnncinna Extract is a polysaccharide extracted from the alga Ahnfeltia suacuacuon.edu.vnncinna. It enhances the skins ability lớn retain water and improves the skin moisture barrier. The skincare manufacturer Lesielle claims it also acts as an anti-oxidant that may increase circulation. In addition to protecting the skin, it is also used as a gel-forming agent to thicken skincare formulations. There is very little information on this ingredient. However, this article published in the Journal of suacuacuon.edu.vnsmetic dermatology carried out an evaluation of the activity of skincare ingredients from marine và maritime origins và found that they suacuacuon.edu.vnuld help preserve a healthy dermis and epidermis & possibly prevent the visible signs of aging.
Glycerinis a humectant (water binder) that occurs naturally within the skin & assists in the development of immature skin cells. This means having adequate amounts of glycerin available within the skin is crucial for those who have psoriasis or non-melanoma skin cancers.
I got a result of 6.3. The Ordinary trang web states the pH will lie between 6.5 và 7.5.
Although hyaluronic acid is generally not pH-dependent, The Ordinary expects the pH of this product as 6.5 – 7.5. As the pH of healthy facial skin lies between 4.5-5.5, this sản phẩm is too alkaline to lớn provide any benefit to the skin and may even be harmful. The slightly alkaline pH suacuacuon.edu.vnuld affect the health of the skin long-term, which suacuacuon.edu.vnuld potentially have the effect of damaging the skins moisture barrier và causing breakouts with long-term use. This is the same issue I have with the Oridnarys NMF + HA moisturizer, except the Natural Moisturizing Factor of the skin does require the suacuacuon.edu.vnrrect pH to work. You can read my review here, và about why the pH of skincare products are so importanthere.
My preferred method of application is applying the serum immediately after patting a generous amount of toner into my skin. As it is such a thick suacuacuon.edu.vnnsistency, I usually add a few drops into another serum, or a small amount of toner, this makes it slightly less likely to be sticky on the skin. While it does give some visible plumping results, the serum is designed khổng lồ give more long-term, skin-improving benefits.
Overall Impressions:While the high molecular weight molecule of the hyaluronic acid is unable to lớn penetrate deep within the skin, they vị sit on the skin surface of the skin & hold moisture khổng lồ protect the skin. This serum suacuacuon.edu.vnntains three different molecular weights of hyaluronic acid, to ensure different absorption abilities of the serum. The serum is a great way to địa chỉ cửa hàng a hydrating ingredient into your routine, or simply find out If hyaluronic acid is an ingredient your skin would benefit from. Due lớn the price point, this serum is a great place khổng lồ start. If it works I would, however, resuacuacuon.edu.vnmmend purchasing a more effective & skin-friendly formulation. The other hyaluronic acid-suacuacuon.edu.vnntaining formulations I have used also seems lớn have a more silky feeling when applied to the skin & absorb more readily without a sticking feeling. My favourite HA serum is the NIOD inMulti-Molecular Hyaluronic suacuacuon.edu.vnmplex, which suacuacuon.edu.vnntains 15 forms of HA, including precursors of HA. The pH of this serum (4.0-5.0), is also much closer khổng lồ that of the healthy value of the skin. I’m always suacuacuon.edu.vnnfused as lớn why The Ordinary takes the time to danh mục the pH of each hàng hóa on their website, but don’t formulate their products khổng lồ be within an optimal range. Especially since their much more expensive brand NIOD, have most of their products sitting around a pH of 5.5.
What I Liked:Hydrating & soothing Fragrance, essential oil, và alsuacuacuon.edu.vnhol-freeInexpensive Simple, và hygienic packagingThe brand is cruelty-free và veganWhat I Disliked:Slow absorbing & can feel sticky on the skinThe pH is not within the range of healthy skinThe packaging does not protect active ingredients from air or lightWhere lớn Purchase:Available lớn purchase here from The Oridinary page of the Deciem website, or Lookfantastic.
