Ingredients higher up in an ingredient list are typically present in a larger amount. Dimethyl Isosorbide (often shortened to DMI) is a sugar-derived solvent made from sorbitol. It's used to dissolve tricky ingredients and help them mix smoothly into a formula. Many actives sit as gritty crystals when undissolved, so DMI swoops in to full dissolve them. This helps improve texture, stability, and how evenly an active is distributed. It does have a penetration-enhancing reputation that is a bit more nuanced than marketing suggests; a cell study on human skin found that 10% DMI didn't significantly boost the permeation of Hydroquinone, Salicylic Acid, or Octadecenedioic Acid compared to controls (though it did improve their solubility in the formula itself). Typical usage concentrations usually range from 1-10% depending on the formula's needs; this ingredient is also well tolerated at these levels. Helianthus Annuus Seed Oil is a plant oil derived from the seeds of a sunflower. It is rich in fatty acids, primarily linoleic acid and oleic acid. This gives it emollient and skin conditioning properties. The reason this ingredient is so effective is because it forms a thin film on the skin that reduces transepidermal water loss (TEWL) while supplying linoleic acid to the stratum corneum to improve barrier strength. The high linoleic acid content is particularly noteworthy for acne-prone skin. Research suggests that acne-prone skin tends to be deficient in linoleic acid in sebum. Topical application may help replenish this to support a healthier follicular environment and less comedone-promoting sebum. One randomized study found sunflower seed oil preserved skin barrier integrity in adult volunteers with and without atopic dermatitis (outperforming olive oil). This ingredient is well-studied, gentle, and an effective emollient suitable for most skin types. On fungal acne: This ingredient may not be Fungal acne (Malassezia folliculitis) safe. This is because it contains fatty acids with carbon chain lengths in the C11-C24 range. Hydroxypinacolone Retinoate (aka Granactive Retinoid or HPR) is a retinoid that is part of the same vitamin A family as retinol. It is an ester of retinoic acid that binds directly to your skin's retinoic acid receptors so it doesn't need your skin to convert it through several steps before it can do anything. In practice, this means it does the classic retinoid jobs in a formula: The best part is that it can do all this with noticeably less redness, flaking, and stinging than traditional retinoids. That gentle reputation is backed by lab work as well; a 2018 study on skin models found that HPR triggered higher retinoid-gene activity than retinol, retinal, or retinyl propionate at the same concentrations while being less irritating to cells. It also boosted procollagen production to levels similar to retinoic acid itself. A 2023 study showed HPR works synergistically with retinyl prop
