01 The score breakdown
UV protection How hard it blocks UVA + UVB across the spectrum at the stated SPF/PA. 58
Filter modernity Dings legacy filters (octinoxate, oxybenzone); rewards photostable next-gen ones. 50
Sensitivity safety Risk for reactive skin — fragrance, alcohol, and known sensitisers. 40
Reef / env. safety Reef toxicity plus how biodegradable the UV filters and surfactants are. 100
Cosmetic elegance Spread, finish, white-cast, and how it actually feels on skin. 75
Health safety Endocrine concerns and systemic absorption signals across the whole formula. 50

UVA-I 340–400nm UVA-I (340–400nm) — covered UVA-II 320–340nm UVA-II (320–340nm) — covered UVB 290–320nm UVB (290–320nm) — not covered
Avobenzone Legacy Older organic filter. Photostable in combination; some literature concerns.
03 The facts, at a glance
Protection
Filter type Mineral filters (zinc oxide, titanium dioxide) sit on skin and reflect UV. Chemical filters absorb UV. Hybrid runs both.
Chemical
Broad spectrum Covers both UVA and UVB. UVA drives aging and deeper damage; UVB gives you burns.
No
Formulation & feel
Texture How it feels going on — milk, gel, cream, spray, stick, essence, lotion, powder, or cushion.
Essence
Finish How it looks once dry: matte, natural, dewy, or glowy.
Natural
Tinted Adds sheer pigment (iron oxides) that masks the white cast common to mineral filters and gives a skin-tone finish.
No
Fragrance-free No synthetic perfume added. Not FDA-defined in the US; the EU requires 'Parfum' + the 26 named allergens on the label. 'Unscented' is different — it can hide masking fragrance. Botanical oils still scent.
No
Alcohol-free No drying short-chain alcohols (alcohol denat., SD alcohol, ethanol). Doesn't mean fatty alcohols like cetyl or stearyl — those are emollients.
Yes
Verdict Is it worth it?

An essence-textured SPF with avobenzone as the listed UV filter, niacinamide, panthenol, and a multi-form hyaluronic complex. Added fragrance plus five disclosed fragrance allergens narrow the audience for reactive skin.

Pros
  • Lightweight essence texture
  • Free of drying alcohol
  • Niacinamide and panthenol for skin support
  • Multi-form hyaluronic acid blend
  • Madecassoside and herbal-water base for soothing
Cons
  • Contains added fragrance and five disclosed allergens
  • Avobenzone as the sole listed UVA filter, no modern stabilizers
  • No PA rating disclosed
  • Single-filter UVA system limits redundancy

Who it's for: Buyers who want a lightweight serum-finish daily SPF with a hydration-focused skincare base and tolerate added fragrance.
