ILLIYOON Ceramide Ato Sun Lotion — Soin Solaire Quotidien

This sunscreen concentrates barrier and soothing active ingredients for daily protection without compromise.

Next-generation 5 UV filters (Ethylhexyl Triazone, Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine, Terephthalylidene Dicamphor Sulfonic Acid, Diethylamino Hydroxybenzoyl Hexyl Benzoate, Polysilicone-15): an architecture 100% organic filters, all compliant with European regulations. They cover the entire spectrum — UVB, short UVA and long UVA — for a SPF50+ PA++++, the highest level of protection available. No mineral filter, so no white cast, regardless of phototype.

Nano-encapsulated black soybean ceramide (Cetyl-PG Hydroxyethyl Palmitamide): a biomimetic ceramide extracted from black soybean and reduced to nanoparticles by AmorePacific. This size allows it to penetrate the upper layers of the epidermis to replenish the intercellular cement from within, where a classic ceramide remains on the surface.

Ceramide NP : natural ceramide identical to those produced by the skin. It fills the gaps in the skin barrier and limits transepidermal water loss — a critical point under sun exposure, which massively dehydrates.

High-purity madecassoside (95%) : the star active ingredient of Centella asiatica, isolated here at a rare degree of purity. Instantly soothes heated skin, calms redness, and supports skin repair after exposure.

Cholesterol + phytosphingosine + fatty acids: the essential lipid trio that mimics the natural composition of the stratum corneum. Together, they maintain hydration under the filtering film, without a greasy effect.

Squalane + trehalose + betaine : the hydrating base. Squalane restores the hydrolipidic film, trehalose and betaine retain water in the epidermis — hence the 24 hours of hydration claimed by the brand.

Ginseng extract (Panax Ginseng Root Water) : traditional Korean tonic that stimulates microcirculation and provides antioxidant ginsenosides, supporting UV protection.

Scutellaria extract + Japanese plum + dipotassium glycyrrhizate : botanical trio for anti-redness, which reduces skin reactivity and limits post-exposure heat.

All in a formula composed of over 72% skincare ingredients : this explains the non-sticky texture and invisible finish.

☀️ Morning routine

1. Finish your usual routine (cleanser → serum → moisturizer) and let the skin absorb for 1 to 2 minutes
2. In the last step, apply the Sun Lotion in a generous and even layer — about two fingers' worth of product for the face and neck. A layer that is too thin divides the actual protection by two or three
3. Don't forget the missed areas: ears, nape, back of the hands, bridge of the nose
4. Wait 15 minutes before exposure, to allow the filtering film to form
5. Makeup can be applied on top once the product is well absorbed

🏖️ For prolonged exposure (beach, hiking, terrace)

1. Apply 15 to 20 minutes before going out, on dry skin
2. Reapply every 2 hours, and systematically after swimming, heavy sweating, or towel drying
3. On the body, don't neglect the feet, back of the knees, and parting of the hair

🌙 Evening routine

The Sun Lotion should not be used in the evening. Remove it properly at the end of the day (oily cleanser followed by gentle cleanser — double cleansing is recommended for SPF50+), then resume your usual repairing routine: Ceramide Ato Lotion or Concentrate Cream depending on the season.

This care is aimed at a wide range of profiles:

• Sensitive, reactive, or atopic skin seeking a sunscreen that does not sting and does not worsen redness — fragrance-free, essential oil-free, tested for skin irritation
• Dry to very dry skin that finds classic sunscreens drying: here, more than 72% of care ingredients and an integrated ceramide complex
• Medium to dark skin tired of the white veil: no mineral filter, completely transparent finish
• Combination and normal skin wanting a portable daily SPF under makeup, without a greasy effect or pilling
• Weakened skin post-treatment (retinoids, acids, laser, hair removal) for which photoprotection is non-negotiable
• Families looking for a single face-body tube for the whole household

To nuance if: you are looking for a 100% mineral sunscreen (pregnancy, infants, personal preference) — this formula is exclusively with organic filters. Same if you have already reacted to a chemical filter: do a patch test on a small area (inside of the elbow) 48 hours before use on the face.

Dis the first application: an invisible finish that melts into the skin, without a white cast or film sensation. The skin remains supple and comfortable where a traditional sunscreen pulls or sticks. Immediate soothing sensation on reactive areas thanks to madecassoside.

In daily use: SPF50+ PA++++ — the highest available protection against UVB (burns) and long UVA (premature aging, spots). The brand claims up to 10 hours of UV protection and 24 hours of hydration under normal use.

After 2 to 4 weeks of daily use: the skin barrier is better preserved. Unlike drying sunscreens that encourage skipping days, this one is worn like a skincare product — so it is really applied every day, which is the only thing that matters in photoprotection. The skin texture remains clear, without the usual micro-irritations.

Prolonged use: it is the most cost-effective anti-aging gesture that exists. Prevention of pigmentation spots, photoaging, and sun-related flare-ups on atopic or reactive skin. The ceramide complex maintains the barrier in parallel, instead of weakening it.

Can it be used on the face or only on the body?

Both. The fluid texture spreads well on the face as well as on the arms, neck, or décolleté — that's its purpose: one tube for the whole family and all exposed areas. On the face, use about two fingers of product (the "two-finger" rule) to achieve the stated SPF.

What is the difference with the classic Ceramide Ato Lotion from the same range?

These are not interchangeable products. The Ceramide Ato Lotion is a barrier moisturizer without sun protection. The Sun Lotion is an SPF50+ PA++++ sunscreen that also contains ceramides, but its primary mission is to block UV rays. In practice, they complement each other: classic lotion as a base care (morning and evening), Sun Lotion as the last step in the morning, before exposure. Do not replace your moisturizer with the sunscreen, and vice versa.

Does it leave a white cast?

No. The formula contains no mineral filters — only new generation organic filters. The finish is transparent, without a chalky effect or gray reflection, making it usable on all skin types and under makeup.

At what age can it be applied to a child?

The brand positions it as a family formula, hypoallergenic and tested for skin irritation. That said, dermatologists generally recommend not applying sunscreen before 6 months (shade and covering clothing instead), and to prefer mineral filters for very young children. For a toddler or very reactive skin, consult a pediatrician or dermatologist before use.

Should it be reapplied during the day?

Yes. The brand claims up to 10 hours of UV protection and 24 hours of hydration, but no filter withstands sweat, water, and friction indefinitely. The rule remains: reapply every 2 hours in direct exposure, and always after swimming or heavy sweating.

Is it compatible with an acid-based routine (AHA, BHA, retinol)?

Yes, and it's even essential. Exfoliants and retinoids make the skin photosensitive: a daily SPF50+ is not optional. Here, the bonus is that the ceramides + madecassoside base limits tightness and flaking associated with these actives. Apply it as the very last step in the morning, on dry skin, after your moisturizer.

Is it sticky or greasy?

No. This is the main selling point of the product: lightweight lotion texture, non-greasy soft finish, without the typical sticky film of classic sunscreens. You can get dressed or apply makeup over it without waiting long.

ILLIYOON was born in 2017 within AmorePacific, a South Korean beauty giant, after four decades of research on sensitive and atopic skin. Unlike trendy K-beauty lines focused on radiance, ILLIYOON positions itself as a mainstream dermatological brand: minimalist formulas, clinically tested, with no compromise on tolerance. The name evokes "Yoon," a Korean root meaning "softness" or "润" (moisture in Chinese characters), rooted in the tradition of Asian medicinal herbs.

The core of ILLIYOON's philosophy is the Ceramide Skin Complex™, a patented encapsulation technology co-developed with AESTURA (another brand in the group). Rather than using classic ceramides that are difficult to stabilize, ILLIYOON relies on a biomimetic analogue (Hydroxypropyl Bispalmitamide MEA) that penetrates better and costs less, making barrier care accessible to all. The botanical ingredients — ginseng, perilla, angelica — are inspired by traditional Korean pharmacopoeia revisited by modern science.

The Ato line (referring to "atopic") has achieved rapid success in Asia thanks to its transparent clinical tests and effectiveness on infant eczema. Today, ILLIYOON equips millions of families, from infants to adults, with a common requirement: to restore the barrier function without unnecessary irritants.
