Ceramides cholesterol and fatty acids: barrier cream formula

Ceramides is most useful when discussed as a formulation problem rather than a marketing trend. In 2026, search intent increasingly centers on compatibility, use levels, pH, processing order and ingredient selection for a specific product format. This guide therefore combines formulation logic, a practical prototype and internal navigation to relevant Mylo Opt raw materials.

Lactic Acid 80%, 25 g

Why Small-Batch Formulators Choose This Concentrated Acid

Lactic acid is an organic alpha-hydroxy acid that forms naturally through fermentation of sugars by lactic bacteria, though for industrial use it is produced synthetically in concentrated form. This ingredient belongs to the section Acids, Salts, Alcohols, and Alkalis, which brings together key acidity regulators used across multiple industries. The 25 gram packaging is designed mainly for home-scale cosmetic making and small trial batches, allowing formulators to test a recipe before committing to a larger volume.

The strongest global demand for lactic acid actually comes from outside cosmetics. In the food industry it works as an acidity regulator and preservative in dairy products, marinades, sauces, baked goods and beverages. In the leather and textile industries the compound is used for tanning hides and treating fabrics. In agriculture it forms the basis for silage fermentation, while in pharmaceutical manufacturing it serves as a pH adjuster in topical solutions. Household chemistry also relies on it as an effective descaling agent for removing mineral deposits.

Within skincare formulation, this acid is valued for its gentle exfoliating action on the outer layer of skin, supporting cell renewal and improving texture over time. It is typically added to creams, serums, toners, peels and body lotions during the cool-down phase, once the main emulsion has dropped to around 35-40 degrees Celsius, to prevent breakdown of the active compound under heat. For home and small-batch recipes, a common dosage ranges from 2 to 10 percent of the total formula weight, with careful monitoring of the final pH of the product.

Lactic acid pairs well with other acidic ingredients from the same category, such as Adipic Acid, which is often used as a buffering agent and pH corrector in technical blends. It is also frequently combined with natural preservatives like Sorbic acid, which adds extra stability to the finished product during storage. For formulas focused on skin and hair nourishment, Pantothenic Acid is a useful complementary ingredient often included in comprehensive care recipes.

Store lactic acid in a tightly sealed container, in a cool dry place away from direct sunlight and heat sources, and avoid contact with metal containers to prevent corrosion. When handling the concentrate, gloves and eye protection are recommended to avoid splashes. Beyond cosmetics and food, the compound is also used in small-scale candle and soap crafting as a minor pH-adjusting additive.

Gentle Overnight Renewal Serum

Distilled water 40 ml

Glycerin 5 ml

Hyaluronic acid gel 3 ml

Lactic Acid 80% 2 ml

Combine the distilled water with glycerin and hyaluronic acid gel, stirring gently until fully blended. Once the mixture is uniform, add the lactic acid slowly in small amounts, mixing continuously and checking consistency between additions. Transfer the finished serum into a clean dropper bottle, let it rest for 24 hours before first use, and store in a cool place away from light for up to six weeks.

Замовила олії для волосся. Якість чудова, результат помітний. Волосся стало більш блискучим і міцним. Результатом дуже задоволена!

Хотя я стараюсь использовать более натуральные компоненты для очищения своей кожи, всё же иногда мне приходится прибегать к более сильным составам, которые помогут убрать небольшие морщинки, а также сделают кожу более гладкой и свежей. Открытием для меня стал именно пилинг на основе кислоты молочной, приобрести её было не сложно, да и цена по сравнению с салоном красоты минимальная. Проводила процедуру я курсами, сначала шесть сеансов, а затем по три в определенное время года. Эффект от средства мне очень понравился, вещество не слишком агрессивное, оно более мягко и щадяще очищает кожные покровы от мелких старых чешуек кожи, а также кислота омолаживает и подтягивает контуры лица.
