Take the skin testShield your skin with the Dr. Ceuracle Cica Regen Waterproof Sun SPF50+ PA++++, a gentle yet powerful vegan-certified chemical sunscreen that delivers broad-spectrum protection while soothing and hydrating the skin. Enriched with calming Centella Asiatica Extract and nourishing Bamboo Complex, this formula defends against environmental stressors and irritation. Its light, emulsion-like texture absorbs quickly, leaving a moisturized, non-sticky finish that’s perfect for daily wear. Waterproof, reef-safe, and suitable for all skin types, this sunscreen offers long-lasting hydration and reliable UV protection.
Cica Regen Waterproof Sun is a lightweight sunscreen from Dr. Ceuracle, a brand based in Korea. Its job is UV protection, with the rest of the formula working on hydration. The ingredient list runs to 46 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 Butylene Glycol, 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, Uvinul A Plus, Mexoryl XL and Tinosorb M. 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, Glycerin, Butylene Glycol and Sodium Hyaluronate.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Diethylamino Hydroxybenzoyl Hexyl Benzoate, Centella Asiatica Extract, Niacinamide and Ulmus Davidiana Root Extract.
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 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.
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
Fades hyperpigmentation and evens out dark spots over time
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.
A photostable replacement for avobenzone: it peaks at 354 nm, deep in UVA I, and does not need a stabiliser to survive the day.
Oil-soluble and broad-spectrum, with two absorption peaks covering UVB and UVA.
A hybrid: it absorbs like an organic filter and scatters like a mineral one, because it is dispersed as microfine particles rather than dissolved.

At the last stage of skin care, apply a moderate amount thoroughly to the skin at least 30 minutes before sun exposure or swimming.
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.
One ingredient could feed malassezia: Polyglyceryl-3 Methylglucose Distearate. That describes the yeast's food supply, not a prediction that it 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 Polymethylsilsesquioxane, Drometrizole Trisiloxane, Caprylyl Methicone.
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 filters UV with Uvinul T 150 (ethylhexyl triazone), Uvinul A Plus (diethylamino hydroxybenzoyl hexyl benzoate), Mexoryl XL (drometrizole trisiloxane), Tinosorb M (methylene bis-benzotriazolyl tetramethylbutylphenol).
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.
