Silk Hydration Weightless Sunscreen Lotion SPF 30
Why this score
Concern48 / 55
- No ingredients carry meaningful, evidence-backed concern.
How much genuine, cited concern the ingredients carry, weighted by how much of each is likely present and whether the product stays on or rinses off.
Transparency12 / 20
- Uses an undisclosed "fragrance/parfum" blend, so its scent allergens are hidden.
Whether the full ingredient list, and any fragrance, are actually disclosed.
Formulation restraint19 / 25
- 1 known irritant or fragrance-allergen ingredient: Octocrylene.
Needless irritant or allergen load for the product type. A clean, purposeful formula scores well without any "free-from" theater.

What’s inside
AvobenzoneGenerally safe
A widely used organic UV-A filter in sunscreens. It can lose effectiveness in sunlight unless paired with photostabilizers, but safety reviews have not found it to pose a meaningful health hazard at approved use levels.
Full ingredient details →HomosalateLimited concern
A UV-B filter used in sunscreens. After reassessing hormone-activity data, the EU lowered its permitted maximum concentration as a precaution, but concluded the ingredient remains safe for use at the new lower limit.
Full ingredient details →OctisalateGenerally safe
A mild UVB chemical filter usually used to help dissolve and stabilize other sunscreen actives. It has a long OTC history at US-approved levels with a low rate of reported irritation.
Full ingredient details →OctocryleneWatch if sensitive
An organic UV-B filter that also stabilizes other sunscreen actives like avobenzone. The EU SCCS reviewed it and concluded it is safe at current use levels, though rare contact allergy has been reported and older, degraded product may form small amounts of benzophenone.
Full ingredient details →WaterGenerally safe
The base most products are built on. It carries the other ingredients and has no safety concern.
Full ingredient details →IsohexadecaneGenerally safe
This branched hydrocarbon is one of the isoparaffins the CIR Expert Panel reviewed and found safe as used in cosmetics, including as an emollient in leave-on face creams. It is generally considered non-comedogenic and used mainly to give a lightweight, non-greasy skin feel.
Full ingredient details →Butylene GlycolCommonly feared, low 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.
Full ingredient details →Cetearyl AlcoholCommonly feared, low concern
A blend of cetyl and stearyl fatty alcohols used to thicken lotions and soften skin. It is chemically unrelated to drying alcohols like ethanol, and the CIR expert panel has found fatty alcohols safe as used in cosmetics.
Full ingredient details →Below the 1% line
PhenoxyethanolCommonly feared, low concern
A widely used preservative, safe at the legal limit of 1% or less. Often the "paraben-free" replacement.
Full ingredient details →Caprylyl GlycolGenerally safe
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.
Full ingredient details →FragranceWatch if sensitive
An undisclosed scent blend that can contain dozens of components. The single most common cause of cosmetic contact allergy, and the blend is not itemized, so you cannot see what is in it.
Full ingredient details →MethylparabenCommonly feared, low concern
A preservative that keeps products free of mold and bacteria. Reviewed repeatedly and considered safe at the low levels used.
Full ingredient details →PropylparabenCommonly feared, low concern
A member of the paraben family used to prevent microbial growth in cosmetics. Like methylparaben, it has been reviewed extensively and found safe at the concentrations used in leave-on and rinse-off products.
Full ingredient details →Disodium EDTACommonly feared, low concern
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.
Full ingredient details →Xanthan GumGenerally safe
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.
Full ingredient details →Tocopheryl AcetateCommonly feared, low concern
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.
Full ingredient details →Titanium DioxideCommonly feared, low concern
A mineral UV filter and white pigment used in sunscreens and makeup. It sits on the skin surface rather than being absorbed, and major regulators consider it safe for topical cosmetic use.
Full ingredient details →PanthenolGenerally safe
A soothing humectant that helps skin and hair look conditioned. Very well tolerated.
Full ingredient details →Aloe VeraGenerally safe
A plant-derived water or extract used mainly as a soothing humectant filler. Evidence for dramatic skin benefits beyond mild hydration and soothing is limited, but it is well tolerated by most people.
Full ingredient details →Sodium Ascorbyl PhosphateGenerally safe
This is a stable, water-soluble derivative of vitamin C that converts to ascorbic acid in skin and is used for antioxidant and brightening support. It is generally better tolerated than plain ascorbic acid and has a low reported rate of irritation in formulation testing.
Full ingredient details →Note: this product hides its scent as an undisclosed “fragrance/parfum” blend, so its specific allergens are not on the label.
