Sérum Uniformizador

The base most products are built on. It carries the other ingredients and has no safety concern.

A form of vitamin B3 used to support a more even-looking tone and a comfortable barrier. Well tolerated at cosmetic levels.

A corn-derived solvent and humectant that has largely replaced propylene glycol in "clean" formulas; CIR reviewed the alkane diol group and found use concentrations up to about 40 percent in leave-on products like deodorant sticks with no meaningful irritation signal.

A light, fast-absorbing emollient that improves spreadability and gives a silky finish without grease. It is well tolerated and graded low concern in published assessments.

A light coconut-derived emollient ester used as a natural-feeling alternative to silicones, giving a dry, velvety finish. It is well tolerated and graded low concern in published assessments.

A humectant that draws water into the skin. One of the best-studied, best-tolerated ingredients in personal care.

A lightweight, odorless emollient made by combining coconut or palm-derived fatty acids with glycerin. It spreads easily, feels non-greasy, and has a long history of use in skin and hair products with no meaningful irritation or sensitization signal.

A light plant oil from wild rosehip seeds, used for skin conditioning and antioxidant support in cosmetics. Well tolerated in most formulations, though botanical origin means rare allergic or sensitizing reactions are possible; patch testing is recommended for people with known plant sensitivities.

Tranexamic acid is used topically at low concentrations to help even the look of dark spots and redness-related discoloration. It has an extensive systemic safety record as an oral medicine, and topical skin absorption is minimal, though a dedicated cosmetic-specific safety review has not yet been published by the main cosmetic safety panels.

A preservative and antioxidant that helps prevent microbial growth and oxidative degradation in formulas. Published assessments support its use at cosmetic levels.

An antioxidant that helps protect a formula and condition skin. Well tolerated.

Derived from olive oil fatty acids, this PEG-free emulsifier is used at low concentrations to hold water and oil phases together in creams. Available safety and dermatological testing has not shown meaningful irritation or sensitization at use levels.

An olive-oil-derived emulsifier, almost always paired with cetearyl olivate, that holds water and oil together and leaves a light skin-like finish. It is well tolerated and graded low concern in published assessments.

Caprylyl glycol is a plant-derived humectant that also has mild antimicrobial properties, so it is commonly paired with other preservatives to allow lower overall preservative levels. Available data do not point to meaningful irritation or sensitization concerns at typical use levels.

A rich plant butter pressed from shea tree nuts, valued for softening and cushioning dry skin. It is generally well tolerated, though very rare allergic reactions have been reported and people with tree nut allergies who are cautious may want to patch test first.

A crosslinked acrylic polymer that thickens and stabilizes formulations. Published assessments show it to be well tolerated at cosmetic use levels, with no evidence of penetration into viable skin layers or systemic absorption.

A synthetic gelling and stabilizing polymer that gives lotions and gels their smooth, cushiony texture. The large molecule stays on the skin surface rather than penetrating, and it is graded low concern in published assessments.

A soothing plant extract traditionally used in skincare, valued for its potential anti-inflammatory properties. Published assessments note it is generally well tolerated in cosmetic formulations, though people with sensitivities to botanicals may want to patch test.

Another sugar-and-fatty-alcohol derived non-ionic surfactant, structurally close to coco-glucoside but made from a shorter (decyl, C10) fatty chain. It is a gentle cleanser generally well tolerated, though a small number of contact-allergy case reports exist, mostly in people with pre-existing skin conditions.

A phospholipid emulsifier from soy or sunflower that binds water and oil and helps other ingredients absorb. It is a natural component of skin membranes, well tolerated, and reviewed as safe as used; a soy-derived grade is not a meaningful concern for a soy food allergy because the protein is largely absent.

A gentle humectant derived from glucose. It draws water to the skin and is mild enough for sensitive skin types. Widely used in cosmetics without reported safety concerns.

Used in tiny amounts to set a product to skin-friendly pH. No concern at those levels.

A plant-derived emollient and preservative formed from glycerin and caprylic acid (coconut) that helps retain moisture and supports formula stability through mild antimicrobial activity.

A sugar-derived, biodegradable cleansing surfactant made from coconut/palm fatty alcohol and glucose; it is markedly gentler than sulfates and is the workhorse of "sensitive skin" or fragrance-free cleansers. CIR reviewed it with other alkyl glucosides and found it safe as used when the finished product is formulated to be non-irritating.

A more stable, esterified form of vitamin E used as an antioxidant and skin-conditioning ingredient. It is a different substance from the vitamin E acetate implicated in vaping-related lung injury, which involved inhaling the oil, not applying it topically to skin.

A fat-soluble vitamin C ester that provides antioxidant activity on skin. It is more stable than free ascorbic acid and is graded low concern in published assessments, with rare reports of sensitization at high concentrations.
