Lactic Acid is a milder, more hydrating alternative to Glycolic Acid, making it a favorite in the US for those who seek professional resurfacing results without excessive downtime or barrier stress. This high-strength 10% concentration works by dissolving the biological bonds that hold dead skin cells to the stratum corneum, facilitating a more efficient cellular turnover process. By clearing away this surface debris, the serum reveals a measurably smoother, more luminous, and uniform complexion underneath. To further support skin health and comfort, the formula is fortified with a purified Tasmanian Pepperberry derivative, known for its ability to reduce the inflammation and sensitivity often associated with chemical exfoliation. Additionally, the inclusion of Hyaluronic Acid ensures that the skin remains hydrated during the resurfacing process, preventing the dryness and \"tight\" feeling that can occur with lower-quality acids. Whether you are addressing early signs of aging, dullness, or uneven skin grain, this solution provides a clear, science-backed route to revitalized and radiant skin.

For American consumers living in high-pollution metropolitan hubs like New York City, Chicago, or Los Angeles, the daily accumulation of urban particulate matter can lead to \"City Skin\"—characterized by chronic congestion, sallow dullness, and environmental sensitivity. Conversely, in the arid climates of the Southwest or the moisture-sapping winters of the Northeast, the skin’s barrier is often compromised, making traditional exfoliants feel too aggressive. The Ordinary Lactic Acid 10% + HA is a US essential because it provides a \"smart\" approach to resurfacing. As a larger molecular weight AHA, Lactic Acid penetrates the skin more slowly than Glycolic Acid, providing a controlled exfoliation that is ideal for the diverse US complexion. Its hydrating properties are perfectly suited for the fast-paced American lifestyle, offering a clinical-grade \"glow-up\" that supports the barrier while refining the grain. Whether you are navigating the smog-heavy commute of Houston or the dry air of a transcontinental flight, this serum provides the resilient resurfacing infrastructure needed to keep your skin looking polished and vibrant in any regional environment.\u003c\/p\u003e\n\n\u003cdiv\u003e\u003cstrong\u003eKey Benefits of The Ordinary Lactic Acid 10% + HA\u003c\/strong\u003e\u003c\/div\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Surface Resurfacing:\u003c\/strong\u003e Effectively dissolves dead skin cell buildup to reveal a measurably smoother and brighter skin surface.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntensive Radiance Boost:\u003c\/strong\u003e Works to eliminate sallow dullness and lackluster skin tone for a vibrant, healthy-looking US glow.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRefines Skin Texture:\u003c\/strong\u003e Visibly smooths out rough patches and minor surface irregularities, promoting a more uniform skin grain.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnifies Uneven Skin Tone:\u003c\/strong\u003e Helps to balance the appearance of localized discoloration and minor post-inflammatory marks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperior Hydration Support:\u003c\/strong\u003e Fortified with Hyaluronic Acid to ensure the skin remains plumped and comfortable during exfoliation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoothing Tasmanian Pepperberry:\u003c\/strong\u003e Infused with a botanical derivative clinically shown to reduce the irritation associated with acid use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Strength Potency:\u003c\/strong\u003e A 10% concentration for those whose skin has built a tolerance to milder exfoliants and requires deeper results.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimizes Absorption:\u003c\/strong\u003e By clearing the path of dead skin cells, it allows subsequent serums and oils to penetrate more effectively.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-Comedogenic \u0026amp; Oil-Free:\u003c\/strong\u003e A lightweight, aqueous formula that provides intensive resurfacing without clogging pores.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Versatility:\u003c\/strong\u003e A fundamental exfoliation layer that is effective and safe for most US skin profiles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRapid Absorption Formula:\u003c\/strong\u003e Sinks in instantly with zero residue, perfect for effortless layering in a busy American routine.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSustainably \u0026amp; Ethically Produced:\u003c\/strong\u003e A 100% vegan and cruelty-free formula that meets the highest US clinical standards.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv\u003e\u003cstrong\u003eKey Ingredients and The Science Behind Them\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cstrong\u003eLactic Acid (10%)\u003c\/strong\u003e\u003c\/div\u003e\n\u003cp\u003eThe core science of this serum is centered on \u003cstrong\u003eLactic Acid\u003c\/strong\u003e, an Alpha Hydroxy Acid (AHA) known for its dual ability to exfoliate and hydrate. In clinical dermatology, Lactic Acid is unique because it is part of the skin's natural moisturizing factors (NMF). Its larger molecular size compared to Glycolic Acid ensures a more gradual penetration, which significantly reduces the risk of acute irritation. At a 10% concentration, it works through a process called \u003cstrong\u003edesquamation\u003c\/strong\u003e, weakening the ionic bonds between corneocytes (dead skin cells) to encourage shedding. This acceleration of turnover not only improves surface texture but also promotes the synthesis of new skin cells. Our formula is held at a pH of approximately 3.8, which is the pKa of Lactic Acid—the precise point where the concentration of free acid and salt are equal, ensuring maximum efficacy and stability.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cstrong\u003eTasmannia Lanceolata (Tasmanian Pepperberry)\u003c\/strong\u003e\u003c\/div\u003e\n\u003cp\u003eTo mitigate the stinging sensation often associated with chemical peels, we have included \u003cstrong\u003eTasmanian Pepperberry\u003c\/strong\u003e. The science of this extract involves a unique compound called polygodial, which has been clinically demonstrated to inhibit the TRPV1 receptors in the skin. These receptors are responsible for sensing the burning signals triggered by acids. By calming these neural pathways, the Pepperberry derivative ensures that the 10% concentration remains comfortable for regular clinical use on the US complexion.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\u003cstrong\u003eSodium Hyaluronate (Hyaluronic Acid)\u003c\/strong\u003e\u003c\/div\u003e\n\u003cp\u003eThe formula is further enhanced with \u003cstrong\u003eSodium Hyaluronate\u003c\/strong\u003e, a salt form of Hyaluronic Acid that possesses a lower molecular weight for deeper penetration. The science of HA involves its incredible ability to bind up to 1,000 times its weight in water. By creating a moisture reservoir within the stratum corneum, it buffers the skin against the potentially drying effects of the acid, leaving the face feeling hydrated and supple rather than stripped.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv\u003e\u003cstrong\u003eSpecifications Table\u003c\/strong\u003e\u003c\/div\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Name\u003c\/td\u003e\n\u003ctd\u003eLactic Acid 10% + HA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eThe Ordinary\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFormat\u003c\/td\u003e\n\u003ctd\u003eWater-Based Aqueous Serum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eKey Active\u003c\/td\u003e\n\u003ctd\u003e10% Lactic Acid (AHA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH Level\u003c\/td\u003e\n\u003ctd\u003eApproximately 3.6 – 3.8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTargets\u003c\/td\u003e\n\u003ctd\u003eDullness, Textural Irregularities, Uneven Tone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuited To\u003c\/td\u003e\n\u003ctd\u003eAll Skin Types (Ideal for Dry or Sensitive Profiles)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVolume\u003c\/td\u003e\n\u003ctd\u003e30mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVegan \/ Cruelty-Free\u003c\/td\u003e\n\u003ctd\u003eYes \/ Yes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUS Availability\u003c\/td\u003e\n\u003ctd\u003eOfficial US Store — theordinaryusa.co\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cdiv\u003e\u003cstrong\u003eHow to Use The Ordinary Lactic Acid 10% + HA\u003c\/strong\u003e\u003c\/div\u003e\n\u003cp\u003eTo maximize the resurfacing and hydrating results of this high-strength serum, follow these professional application protocols:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003ePreparation:\u003c\/strong\u003e Start with a clean, dry face.
