Independently verified by The Clean Sheet
Daily Sun Fluid
SPF 50 · PA++++ · 50 ml
Meridian Skin · invented brand, illustrative only
The Clean Sheet is an independent assessor. Meridian Skin commissioned this verification and paid for it. The findings, and the decision to publish them, were ours alone. The fee covered the assessment and could not buy its outcome.
58.4
Measured SPF
ISO 24444, in vivo, 10 valid subjects. Label claim is 50.
18.2
Measured PPD
ISO 24442, in vivo. PA++++ requires 16 or above.
378 nm
Critical wavelength
ISO 24443. Broad spectrum requires 370 nm or above.
82%
SPF retained in water
ISO 16217, two 20-minute immersions. Threshold is 50%.
What was verified
SPF
Measured 58.4 (SD 12.1, n = 10)
SPF 50
Independently re-tested on a unit bought from open retail. The measured mean and its confidence interval support the labelled value. The label is conservative against the result, which is the correct direction.
UVA
Measured PPD 18.2
PA++++
In-vivo persistent pigment darkening, ISO 24442. PA++++ requires a PPD of 16 or above. The UVA-PF to SPF ratio is 0.34, above the one-third minimum for broad spectrum.
Water resistance
82% of initial SPF retained
“Water resistant”
ISO 16217, two 20-minute immersions. The claim printed on the pack matches the protocol that was actually run — which is not always the case.
Photostability
94% SPF retained after UV dose
Protection holds through the day
The filter system does not degrade meaningfully under sustained UV exposure. An SPF certificate on its own will never show you this.
Filter legality
5 filters, all within permitted limits
All filters lawful in India
Every UV filter and its concentration checked against the Cosmetics Rules 2020. Also cleared against EU Annex VI, because this brand declared an export market.
Sample identity
Formula version and batch matched
The tested product is the shipping product
The formula tested is the formula on sale. This is the checkpoint products most often fail, and almost never for dishonest reasons.
Labelling
All required particulars present
Statutory label complete
Cosmetics Rules 2020 and Legal Metrology requirements: licence number, batch, dates, net quantity, ingredient order, directions and warnings.
Claim language
12 supported · 2 amended before publication
14 live claims reviewed
Every SPF-related claim across the website, pack, ads and marketplace listings. Two were amended by the brand before this page was issued. Both are named in the scope note below.
The filter system, in full
A sunscreen is only as good as the filters in it and their stability together. These are the five in this formula, each checked for legality and concentration, and the combination checked for whether it survives a day in the sun.
Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine
3.0%
UVA and UVB, photostable
Ethylhexyl Triazone
3.0%
UVB, high efficiency
Diethylamino Hydroxybenzoyl Hexyl Benzoate
4.0%
UVA, photostable
Tris-Biphenyl Triazine
5.0%
Broad spectrum, particulate
Titanium Dioxide
2.5%
Broad spectrum, mineral
Concentrations are published here because the brand agreed to it. They are not required to, and a page without them is not a weaker verification.
How this was tested
The sample was bought, not supplied
A sealed unit purchased from open retail in Mumbai on 22 April 2026. The brand did not know which unit or which batch. Chain of custody documented from purchase to laboratory.
The laboratory was chosen by us
A NABL-accredited laboratory, accreditation current at the date of testing, with each method inside its accredited scope. The Clean Sheet instructed the lab directly. The brand paid the laboratory at cost, with no margin to us.
The brand saw the findings before publication
Draft findings were issued with five working days to submit further evidence or correct a factual error. The verdict itself was not open to negotiation, and this is written into the engagement.
A second assessor reviewed the decision
The person who sold the engagement did not decide its outcome. Every verdict is reviewed independently before it is communicated or published.
What this does not cover
Please note. A verification that does not state its own limits is worth less, not more. These are ours.
- —Any claim not listed on this page. Two claims were amended before publication: a “12-hour protection” claim, withdrawn for want of supporting data, and “sweat-proof”, which is not a permitted claim in any case.
- —Suitability for any individual person, skin type or condition. This is a verification of evidence, not medical advice.
- —Batches other than the one tested, and any formulation change made after the assessment date.
- —The brand’s other products. Verification is per product, never company-wide.
- —Regulatory approval of any kind. This is a voluntary private assessment and does not replace licensing or compliance obligations.

Status
Sample. No verification in force.
Verification is point-in-time. It voids automatically if the formulation, the manufacturing site or the claims change, and it can be withdrawn if a later market check contradicts this result. Withdrawals are published. On a live page, this panel is where you would confirm that a verification is still in force.
Sample page. Not a verification. Meridian Skin is an invented brand and this product does not exist. Every figure below is illustrative, shown so brands can see the format of the page they would receive. No product has been verified by The Clean Sheet on this page.
This is the page your product would get
Permanent, public, QR-linked from your pack, and written so a shopper can read it without knowing what ISO 24444 is.
The Clean Sheet is an independent private certification scheme being designed in alignment with ISO/IEC 17065 and ISO/IEC 17067. It is not currently accredited.
