Take the skin testA great organic sunscreen that goes beyond mere sun protection. Enriched with a powerful blend of fructan and ten types of hyaluronic acid, this sunscreen not only shields your skin from harmful UV rays but also works tirelessly to infuse your skin with deep, lasting moisture. Experience the ultimate hydration boost as this innovative formula locks in moisture, leaving your skin supple, plump, and incredibly nourished. Reinforcing your skin's natural defenses is a top priority, and that's why it incorporated the dynamic duo of panthenol and niacinamide into the mix.
Hyal Reyouth Moist Sun SPF50+ PA++++ is a lightweight sunscreen from Dr. Ceuracle, a brand based in Korea. 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 42 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, Glycerin and Sodium Hyaluronate, humectants that pull water into the upper layers of skin rather than sealing it there.
It is a chemical (organic-filter) sunscreen, using Uvinul T 150, Mexoryl SX, Parsol SLX, Uvinul A Plus and Tinosorb S. 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: Very high. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Propanediol, Glycerin, Sodium Hyaluronate and Ethylhexylglycerin.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Diethylamino Hydroxybenzoyl Hexyl Benzoate, Panthenol, Niacinamide and Sodium Hyaluronate.
On richness alone it suits Balanced, Combination (oily) and Oily 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 essential-oil-free, no drying alcohol, paraben-free, microplastic-free, sulfate-free and dye-free. Those claims come from the ingredient list itself, not from the packaging. It does contain fragrance, worth knowing if your skin reacts to any of them.
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.
This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.
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
Boosts collagen and cell turnover to reduce fine lines and wrinkles
Calms redness, irritation, and inflammation for sensitive skin
Brightens and balances complexion for a more uniform appearance
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.
Chemical (organic) filter system · broad-spectrum through UVA I
The most efficient UVB absorber available by weight, which is why high-SPF formulas reach SPF 50+ without feeling heavy. Contributes nothing to UVA.
Water-soluble UVA filter, which is unusual — most UVA filters are oil-soluble.
A polymer, so it stays on the surface of skin rather than penetrating — low irritation potential and no measurable systemic absorption.
A photostable replacement for avobenzone: it peaks at 354 nm, deep in UVA I, and does not need a stabiliser to survive the day.
One of the most photostable filters in use, and it stabilises avobenzone and octinoxate alongside it. Oil-soluble, cosmetically light, no white cast.

Judged on how rich the formula reads from its ingredient list, it suits Balanced, Combination (oily), Oily 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: Polyglyceryl-3 Distearate, Glyceryl Stearate, Glyceryl Stearate Citrate. 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.
No — it contains Parfum.
No. Reading the full ingredient list, this formula is no drying alcohol.
No — it contains Polysilicone-15.
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 42 ingredients, of which 13 are recorded as actives.

It filters UV with Uvinul T 150 (ethylhexyl triazone), Mexoryl SX (terephthalylidene dicamphor sulfonic acid), Parsol SLX (polysilicone-15), Uvinul A Plus (diethylamino hydroxybenzoyl hexyl benzoate), Tinosorb S (bis-ethylhexyloxyphenol methoxyphenyl triazine).
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.
Unlikely. It filters with organic (chemical) filters only, which dissolve into the formula rather than sitting on the surface, so they do not leave a white cast.
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.
