Take the skin testThe ISNTREE Hyaluronic Acid Natural Sun Cream is a mineral-chemical hybrid sunscreen offering powerful SPF50+ PA++++ protection with a lightweight, moisturizing formula. Powered by zinc oxide and enriched with eight forms of hyaluronic acid, niacinamide, panthenol, betaine, inositol, adenosine, and vitamin E, it delivers both sun defense and deep hydration without leaving a white cast. It's fresh, skin-friendly texture absorbs effortlessly, making it ideal for daily wear, even under makeup, especially for sensitive and dehydrated skin.
Hyaluronic Acid Natural Sun Cream SPF50+ PA++++ is a lightweight sunscreen from Isntree. It is rated SPF 50+ PA++++, meaning it is tested to the top of both the UVB and the UVA scales used in Asia. Its job is UV protection, with the rest of the formula working on hydration. The ingredient list runs to 26 ingredients, each broken down in full below.
By its ingredient list the formula reads as light: water and humectants lead, with emollients kept lower in the order. Silicones in the formula tend to give a smooth, blurred finish and help it grip under makeup. Hydration is handled by Propanediol, Ethylhexylglycerin and Sodium Hyaluronate, humectants that pull water into the upper layers of skin rather than sealing it there.
It is a mineral sunscreen, filtering with Zinc Oxide. Between them those filters cover UVB, UVA II and UVA I, so the formula is broad-spectrum in the meaningful sense: it reaches past 340 nm, where the ageing wavelengths sit. Every filter in the formula is photostable, so its protection does not fall away over the first hour in the sun — reapplication is still about sweat, water and rubbing rather than degradation.
Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Propanediol, Ethylhexylglycerin, Sodium Hyaluronate and Betaine.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Panthenol, Zinc Oxide, Niacinamide and Adenosine.
Oil control: Moderate. Ingredients that moderate sebum or absorb shine, and here that comes from Zinc Oxide and Niacinamide.
On richness alone it suits Balanced skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
The formula contributes little or nothing on antioxidant protection, cell renewal and firmness signalling. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.
Reading the full list, the formula is fragrance-free, essential-oil-free, no drying alcohol, paraben-free, sulfate-free and dye-free. Those claims come from the ingredient list itself, not from the packaging.
Use it in the morning. In a routine it goes final morning step, before makeup. Apply about two finger-lengths for the face and neck — under-application is the single most common reason sunscreen underperforms. Reapply every two hours of sun exposure, and after swimming or towelling off. Let it set for a couple of minutes before makeup so it does not pill.

Drawn purely from the ingredient list
Scored on how rich or light the formula reads from its INCI order.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
Based on the curated benefits documented for this product's ingredients.
Attracts and locks in moisture to keep skin plump and dewy
Calms redness, irritation, and inflammation for sensitive skin
Boosts collagen and cell turnover to reduce fine lines and wrinkles
Brightens and balances complexion for a more uniform appearance
Regulates sebum production to reduce shine and greasiness
Tightens and refines the look of enlarged pores
None of the ingredients in this formula are associated with these benefits. This is not unusual, as most products are designed to target a limited number of concerns.
Mineral filter system · broad-spectrum through UVA I
The only single filter that covers the whole UVB–UVA1 range on its own. Scatters and absorbs rather than purely absorbing, and can leave a white cast at high loads.

Judged on how rich the formula reads from its ingredient list, it suits Balanced skin best. It is the least natural fit for Dry, Combination (dry) skin.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
3 ingredients could feed malassezia: Propylheptyl Caprylate, Polyglyceryl-2 Dipolyhydroxystearate, Glyceryl Caprylate. That describes the yeast's food supply, not a prediction that they will cause a breakout.
Nothing in this formula is on the standard pregnancy-caution list. That is not medical clearance — check anything you use daily with your doctor or midwife.
Yes. Reading the full ingredient list, this formula is fragrance-free.
No. Reading the full ingredient list, this formula is no drying alcohol.
No — it contains Cyclohexasiloxane, Polyglyceryl-3 Polydimethylsiloxyethyl Dimethicone, Caprylyl Methicone, Lauryl Polyglyceryl-3 Polydimethylsiloxyethyl Dimethicone.
No. Reading the full ingredient list, this formula is essential-oil-free.
Yes. Reading the full ingredient list, this formula is paraben-free.
It layers well with Vitamin C (L-ascorbic acid), Retinoids (retinol, retinal), AHAs (glycolic, lactic), BHA (salicylic acid), PHAs (gluconolactone), Benzoyl peroxide.
Use it in the morning, final morning step, before makeup.
It lists 26 ingredients, of which 4 are recorded as actives.
Isntree.
It filters UV with Zinc Oxide (zinc oxide).
Yes. Its filters cover UVB, UVA II and UVA I, so protection reaches past 340 nm into the deep-UVA range associated with ageing and pigmentation.
Possibly. It filters with mineral UV filters, which sit on the surface and can leave a visible cast on deeper skin tones, especially at high SPF.
It contains none of the filters named in the Hawaii and Key West reef legislation (oxybenzone and octinoxate). "Reef safe" is not a regulated term, so treat that as a fact about the filter list rather than a certification.
Yes. Let it set for a couple of minutes before foundation so it does not pill, and reapply over makeup with a stick or powder rather than rubbing more in.
Every two hours of sun exposure, and immediately after swimming, sweating heavily or towelling off.
