LiftActiv Vitamin B3 Face Serum for Dark Spots & Wrinkles

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

A lightweight humectant and solvent similar in role to propylene glycol, used to carry actives and give lotions a lighter feel. CIR has reviewed it and considers it safe as used in cosmetics.

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

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

A urea derivative used as a humectant to help skin retain moisture and improve hydration. Published safety assessments find it well tolerated at the use levels in cosmetics.

A small humectant and solvent molecule that helps other ingredients dissolve and helps skin hold water. It is one of the most studied cosmetic ingredients and is considered safe at the concentrations used in personal care products.

The smallest and most penetrating alpha hydroxy acid, used to loosen the bonds between dead skin cells for smoother texture and tone. It is a genuine irritant at higher concentrations or low pH, can increase sun sensitivity, and the EU restricts free acid content and requires sunscreen-use wording on labeling.

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 soothing, skin-conditioning compound (also found in comfrey root) commonly added to calm and hydrate irritated or sensitive skin. It has a long history of safe use with very low irritation potential.

A strong alkali used in tiny amounts to adjust the pH of cosmetics to safe, skin-friendly levels. At the pH found in finished products, sodium hydroxide is neutralized and well tolerated.

A widely used preservative, safe at the legal limit of 1% or less. Often the "paraben-free" replacement.

Chlorphenesin is a preservative subject to an EU maximum concentration limit and has been linked to contact dermatitis in a minority of users, particularly with repeated exposure. Most people tolerate it at the regulated use level without issue.

A gentle, stable vitamin C derivative that the skin converts to active vitamin C, popular for brightening with less irritation than pure ascorbic acid. 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 protein fragment from rice that helps bind water and strengthen hair. It is mild and well tolerated, making it a suitable option for those seeking a plant-derived protein conditioner without the allergen concerns of wheat or other grain proteins.

A biodegradable chelating agent that binds trace metals to stabilize formulas, often chosen as a gentler alternative to EDTA. It is readily degraded in the environment and poses minimal toxicity concerns at cosmetic concentrations.

Xanthan gum is a microbial-fermentation-derived polysaccharide used to thicken and stabilize textures, similarly common in food. Cosmetic panel review of this and related microbial gums found them safe as used, with no meaningful irritation signal at typical concentrations.

Pentylene glycol is a humectant and solvent that also offers mild antimicrobial support in formulas. It is generally well tolerated, with only rare reports of irritation, mostly in already sensitive or compromised skin.
