Introduction
I had an idea!
When creating images of cold toner, you tend to want to add more ice, snowflakes, and blue light.
However, if you add too many symbols of coldness, people will see "beverages," "frozen goods," or "fantasy" before they see skincare.
The star of this show is not ice.
It is glass straight out of the refrigerator.
Condensation of irregular sizes.
Water droplets flowing just a little.
A thin film of water remaining on the bottom.
A very faint chill drifting only at the bottom.
By breaking down coldness into physical phenomena, it becomes easier to arrange it as a cosmetic advertisement while maintaining a sense of coolness.
※This article is an example of image production for a fictional product. It does not guarantee the efficacy, storage methods, or safety of the product. When using it for actual products, be sure to check the product labeling, storage conditions, container specifications, and internal company standards.
1. Translating "cold" into 5 shooting conditions
1-1. Chilled container
For containers, light-colored frosted glass is an easier material to handle than clear glass.
Clear glass tends to pick up lines and props in the background, making the container's outline unstable. Frosted glass makes it easier to maintain the product shape while retaining soft transparency.
However, if you make it too cloudy, it will look like frost or frozen goods. Aim for the middle ground between "translucent frosted glass" and "faintly visible internal water level."
1-2. Irregular condensation
On cold glass, water droplets of the same size do not line up in a grid.
Use fine condensation as a base, place medium-sized droplets here and there, and add only two or three large droplets. Give the large droplets a downward flow.
The point is not to have "lots of water droplets," but to separate them by particle size and role.
1-3. Water film on the contact surface
If a chilled product is placed on a shelf, a thin film of water or a small ring of water will form on the bottom.
Without this contact information, the product will look like it is floating. It is also important not to turn the water film into a large puddle.
1-4. Cold air at a low position
If you are adding cold air, limit it only to the bottom of the bottle.
Spreading white smoke across the entire screen makes it look like a dry ice effect, and the product outline and copy margins will be lost. "Low, thin, and localized" is the standard.
1-5. Not cold colors, but cold light
Simply making the background a deep blue can sometimes make it look like a night view or a home appliance.
Keep the colors muted to milky white and pale light blue, and add a thin backlight to the edge of the glass. Brighten the front with soft diffused light, and do not use blue luminescence.
I see the image now!
It is more natural to adjust the glass's reaction than to make the colors cold.
2. Design of the Example Image
The example is in a 4:5 vertical aspect ratio.
Product: Fictional cooling toner
Container: Pale ice-blue frosted glass
Quantity: 1 bottle
Placement: Slightly to the right of center
Product height: Approximately 55% of the screen
Negative space: 30% in the upper left
Cooling sensation: Fine condensation, large droplets running down, water film on the base, pale cold air at the bottom
Background: Milky white to light blue, with blurred white linen and pale green in the distance
Light: Diffused light from the upper left, thin backlight on the edge of the glass
Text: Do not generate
I have limited it to just one bottle of toner and have not placed any plants or ingredient materials in the foreground. This is to ensure the relationship between the product and the cooling sensation is understood at a glance.
The upper left is the space for adding copy later. I have specified it as an area where water droplets, leaves, and cold air should not be generated.
3. Simple Prompt for Free Public Release
縦長4:5の高品質な夏の化粧品広告。冷蔵庫から出した直後のような、架空の冷やし化粧水を写実的に撮影する。淡いアイスブルーのフロストガラス製円筒ボトルを1本だけ、画面中央より少し右へ垂直に置く。マットホワイトのキャップ、無地の半透明ラベル面、文字・ロゴなし。ボトル上部と側面には大小が不規則な細かな結露を付け、2〜3粒の大きな水滴だけをゆっくり流す。底面には薄い水膜と自然な接地影を入れ、冷気はボトル下部の周囲だけへごく淡く漂わせる。背景は明るい乳白色から淡い水色、遠景にぼけた白いリネンと淡い緑。左上30％はコピー用の静かな余白として空ける。左上からの柔らかな拡散光と、ガラス輪郭を示す細い逆光。実在のスタジオで撮影した日本の美容誌広告のような、清潔で涼しく、光沢を抑えた自然な質感。氷漬け、氷柱、雪の結晶、青い発光、濃い煙、飲料、食品、人物、手、複数商品、変形した容器、プラスチック感、過剰な3DCG、読める文字、ロゴ、透かしを避ける。Additional instructions to reduce failures in the free version
結露は均一な粒にせず、微細な粒を中心に大小を混ぜる。流れる大粒は2〜3本だけに限定する。冷気はボトル下部の外周だけに薄く置き、商品正面と左上の余白を覆わない。Correction prompt for the free version
氷、雪の結晶、青い発光、濃い煙を削除する。冷たさは、冷えたガラスの微細な結露、2〜3本の流れる水滴、底面の薄い水膜、下部だけの淡い冷気で表現し直す。商品をスキンケア用化粧水として最も大きく鮮明に見せる。4. Complete natural language prompt
縦長4:5の上質な夏のスキンケア広告キービジュアル。完全に架空の「冷やし化粧水」を、実在のスタジオで撮影したような写実的な商品写真として描く。
主役は、淡いアイスブルーのフロストガラス製円筒ボトル1本。容量は約180mlに見える自然な縦横比。マットホワイトのスクリューキャップを正しい中心軸で取り付け、正面には無地の半透明ラベル面だけを設ける。ブランド名、商品名、説明文、ロゴ、記号は入れない。内部には透明でさらりとした化粧水がかすかに見える。
ボトルを画面中央より少し右へ垂直に置き、高さは画面高の約55％。カメラはボトルとほぼ同じ高さで、約10度だけ見下ろす。淡い水色のフロストアクリル棚へ自然に接地させ、底面の輪郭、ガラス厚、左右対称の円筒形、キャップの水平を正確に保つ。
冷蔵庫から出した直後のような冷たさを、現実的な物理表現で描く。ボトル上肩と側面には、大小が不規則な微細な結露を付ける。中粒を少量混ぜ、2〜3粒の大きな水滴だけを重力に沿ってゆっくり下へ流す。底面には薄い水膜と小さな水の輪を作る。冷気はボトル下部の周囲だけへ、ごく淡く低く漂わせる。商品正面、上部、コピー余白を煙で隠さない。霜の塊、氷の膜、氷漬けにはしない。
背景は乳白色から淡いアイスブルーへの穏やかな明度差。遠景に白いリネンカーテンとごく淡い緑の葉影を大きくぼかして入れ、季節感だけを添える。左上30％は、後から見出しを置くための静かな余白として完全に空ける。余白には葉、水滴、冷気、反射、小道具を置かない。
左上から柔らかな昼光の拡散光を当て、右後方から細い逆光を入れて、フロストガラスの輪郭、厚み、結露を分離する。正面は明るく清潔に保ち、反射は細く限定する。接地影は薄く自然にする。白飛び、強い鏡面光沢、青い自己発光を避ける。
配色はアイスブルー、乳白色、ごく淡いミント、透明な水。彩度を抑え、清潔で涼しく、静かな日本の美容誌広告として仕上げる。肌への効能、温度変化、毛穴、赤み、鎮静などの効果を示す図解やコピーは入れない。
読める文字、ブランド、ロゴ、透かし、複数商品、人物、手、顔、コットン、飲料用ストロー、グラス、食品、果物、氷漬け、氷柱、雪の結晶、過剰な霜、濃いドライアイス煙、ファンタジーの青い発光、水しぶきの爆発、浮遊物、変形した容器、ずれたキャップ、二重底、プラスチック状のガラス、過剰に滑らかな3DCG、安価なカタログ写真を避ける。5. English prompt
Create a premium vertical 4:5 summer skincare key visual for a completely fictional chilled facial toner, photographed with the realism of a high-end Japanese beauty editorial.
Show one pale ice-blue cylindrical frosted-glass toner bottle, approximately 180 ml, standing upright slightly right of center and occupying about 55% of the frame height. Use a matte white screw cap aligned to the bottle axis and a blank translucent label area. Do not include any brand name, product name, logo, symbol, or readable text. Let the clear watery toner remain faintly visible through the glass.
Place the bottle naturally on a pale ice-blue frosted acrylic shelf. Use a bottle-height camera with a subtle 10-degree downward view. Preserve a perfectly symmetrical cylinder, realistic glass thickness, a level cap, stable grounding, and a clean horizon.
Communicate the exact moment just after refrigeration through believable physical cues. Add fine irregular condensation beads across the shoulders and side walls, a small number of medium droplets, and only two or three larger droplets slowly tracking downward under gravity. Add a thin wet film and a small realistic water ring at the base. Keep an extremely light, low-lying cool mist only around the lower third of the bottle. Do not cover the product front, upper bottle, or copy space. No frost crust, frozen shell, or bottle trapped in ice.
Use a quiet milky-white to pale ice-blue background with a heavily blurred white linen curtain and faint pale-green foliage in the distance. Reserve the upper-left 30% as completely calm negative space for later typography. Keep foliage, droplets, mist, props, and reflections out of this area.
Light the scene with soft diffused daylight from the upper left and a narrow gentle back rim light from the right rear to reveal the frosted-glass edge and condensation. Keep frontal illumination bright and clean. Use a subtle natural contact shadow, restrained reflections, realistic refraction, and reduced gloss.
Color palette: ice blue, milky white, extremely pale mint, and clear water, with restrained saturation. The result must look like a real studio photograph, not a 3D render.
Avoid readable text, logos, watermarks, multiple products, people, hands, faces, cotton pads, drinking straws, glasses, beverages, food, fruit, ice encasing the bottle, icicles, snowflakes, excessive frost, dense dry-ice smoke, fantasy blue glow, explosive splashes, floating objects, distorted packaging, misaligned caps, duplicated bases, plastic-looking glass, overly smooth CGI surfaces, and cheap catalog styling. Do not depict or imply medical, pore-tightening, redness-reducing, soothing, or temperature-related efficacy claims.6. JSON format variable example

13. Common Mistakes and Correction Prompts
Mistake 1: Looks like a beverage advertisement
The cause is having clear liquid, ice, a straw, a glass, and water splashes all present at once.
飲料、グラス、ストロー、氷、果物、水しぶきをすべて削除する。マットホワイトの化粧品用キャップと無地ラベル面を持つ化粧水ボトル1本を最大かつ最も鮮明にする。日本の美容誌に掲載されるスキンケア広告として仕上げる。Mistake 2: Looks like it is frozen or a frozen product
The cause is specifying "cold" too directly through ice or frost.
ボトルを覆う氷、霜の塊、氷柱、雪の結晶を削除する。容器表面は凍結させず、微細な結露、2〜3本の流れる水滴、底面の薄い水膜だけで冷たさを表現する。Failure 3: The smoke is too thick
The cause is that the position and amount of cold air are not specified.
白い煙を80％削減する。冷気は半透明で薄く、ボトル下部の外周だけに低く漂わせる。商品正面、キャップ、左上のコピー余白を完全に見せる。Failure 4: The condensation is uniform and looks like CG
The cause is that the water droplets are all of a single particle size.
結露を格子状・均一に並べない。微細な粒を約80％、中粒を約15％、大粒を約5％の見た目で不規則に分布させる。大粒の流れは2〜3本に限定し、すべて重力方向へ自然に流す。Failure 5: The bottle or cap is deformed
The cause is that the amount of information in the transparent material and water droplets exceeds the container structure.
一本の左右対称な円筒ボトルへ修正する。ボトル中心軸、キャップ中心軸、底面の楕円を一致させる。キャップを水平にし、側面をまっすぐ保ち、二重底、溶けた輪郭、余分な口部を削除する。Failure 6: The negative space is filled
The cause is that only the position of the "negative space" is specified, without defining the prohibited elements.
左上30％を、均一で明るい乳白色から淡い水色の静かな背景として空ける。この領域へ商品、葉、水滴、冷気、反射、影、小道具を入れない。Failure 7: It looks like plastic or 3DCG
The cause is full-surface gloss, uniform surfaces, and strong contour lighting.
フロストガラスの微細な曇り、現実的なガラス厚、限定された細い反射、自然な接地影を追加する。全面的な鏡面光沢、完全に滑らかな表面、青い輪郭発光、樹脂のような透明感を削除する。14. Prohibited Items

Summary
What is important in an advertisement for chilled lotion is not to increase the symbols of coldness.
It is to observe the chilled glass and categorize the phenomena.
Fine condensation
Limited running water droplets
A thin film of water on the bottom
Faint cold air only at the base
Thin rim light
Quiet negative space for copy
By breaking it down this far, you can convey coolness even without using ice.
First, try putting out one shot.
Start by keeping the product and the negative space fixed, and compare by changing only the density of the condensation. Next, by replacing ice blue with mint or lavender, it becomes easier to find the temperature that suits your brand.
