Sunblock Milk Sunscreen SPF48 Pa+++

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

A widely used UVB chemical filter with a long safety record at US-approved concentrations. Some lab and animal studies have raised questions about hormone activity and coral reef impact, which is why a few jurisdictions cap or restrict it, but human-relevant risk at labeled use levels is considered low by regulators.

A starch derivative used to thicken sunscreen lotions and absorb excess oil; the aluminum here is bound in a starch complex, unlike the soluble aluminum salts used in antiperspirants. CIR has reviewed aluminum starch octenylsuccinate and found it safe as used in cosmetic formulations.

A synthetic polymer used to form a water-resistant film and keep chemical UV filters evenly suspended in sunscreen lotions. It is not absorbed through skin and CIR has not flagged it as a safety concern in cosmetic use.

A water-soluble humectant that holds moisture and gives essences a soft feel. It is well tolerated and graded low concern in published assessments.

A light silicone emollient that spreads easily and gives a dry, non-greasy finish, common in Korean sunscreens and primers. It stays on the skin surface and is graded low concern in published assessments.

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.

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.

An organic UVB filter approved in the EU and widely used in Korean and Japanese sunscreens at up to 5 percent. It is highly photostable and shows low skin penetration in the reviewed data. It is not on the FDA-approved UV filter list, so US-formulated sunscreens do not use it; that is a regulatory-process gap rather than a documented safety finding against the ingredient.

A broad-spectrum organic UV filter used widely in European and international sunscreens. Approved by the EU and other regulators as safe at cosmetic levels.

A broad-spectrum organic UV filter that absorbs both UVB and UVA and also stabilizes other sunscreen filters. The EU SCCS reviewed both the standard and nano particle-size forms and concluded it does not pose a risk to consumers on healthy, intact skin at up to 10 percent, citing negligible skin penetration due to particle size.

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

A mixture of fatty alcohols ranging from 14 to 22 carbons, used as emollients and emulsifiers in creams and formulations. The published evidence supports safety at cosmetic levels.

A surfactant derived from stearyl alcohol with a higher degree of ethoxylation than Steareth-2, providing enhanced emulsification. It is graded safe for cosmetic use and well tolerated.

A silicone that gives a smooth, soft feel and helps hold water in the skin. Inert and well studied.

A plant extract used in Korean skincare for its soothing, antioxidant reputation. It is well tolerated with a low reported irritation rate; the soothing claims rest on limited but reasonable evidence.

Bisabolol is a botanically derived (or synthetically nature-identical) compound used for its calming, anti-irritant reputation in sensitive-skin formulas. Safety reviews and long clinical use have found it well tolerated with a low rate of reported reactions.

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 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.

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.

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 chelating agent that binds trace metal ions to keep formulas stable and preservatives working properly. It is not a functional skincare "active" and only a very small amount is used, with minimal skin penetration expected.

A widely used emulsifier and solubilizer that has been in cosmetics and pharmaceuticals for decades. The CIR has assessed it as safe with no known concerns at typical cosmetic concentrations. As with any surfactant, some people with very sensitive skin may experience mild irritation.

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.
