Key Takeaways
- All four keywords — oiled body, glistening skin, shiny skin, and body covered in lotion — add gloss to the skin. The difference from the control (no modifier) with its matte skin is clear.
- The visual difference between the 4 keywords is very small. Any of them produces a “shiny skin” look, and they are practically interchangeable.
- The most token-efficient option is
oiled body(2 tokens).glistening skin(2 tokens) is equivalent, while lotion requiresbody covered in lotionmaking it less efficient. - Gloss expressions are most effective when combined with outfits that expose more skin, such as bikinis. The larger the exposed skin area, the more visible the gloss difference.

| Steps | 8 |
| CFG | 1.0 |
| Size | 1024x1024 |

Base Prompt
The {SKIN_MODIFIER} portion was swapped with the following patterns (control has no modifier):
| Condition | SKIN_MODIFIER |
|---|---|
| A00: Control | (none) |
| A01: oiled body | oiled body |
| A02: glistening skin | glistening skin |
| A03: shiny skin | shiny skin |
| A04: body lotion | body covered in lotion |
Evaluation Criteria
- Gloss level: Strength of light reflection on the skin surface (matte / subtle gloss / strong gloss)
- Gloss distribution: Uniform across the body or only on highlight areas?
- Texture differences: Oil-like, watery, sticky — any qualitative differences?
- Side effects: Unintended impact on outfits or composition
Results by Condition
A00: Control (no skin modifier)
| seed 1 | seed 2 | seed 3 |
|---|---|---|
![]() | ![]() | ![]() |
Observations: Skin has a matte texture with no clear gloss. A typical skin appearance under natural lighting. Seed 1 produces a 3-person split composition (a trait of this seed). Seed 2 has fishnet stockings unintentionally added (possibly pulled by the black bikini). The bikini shape is consistently reproduced as a black triangle bikini in 3/3.
A01: oiled body
| seed 1 | seed 2 | seed 3 |
|---|---|---|
![]() | ![]() | ![]() |
Observations: Clear skin gloss confirmed in 3/3. Compared to the control, a uniform shine is present on the abdomen, chest, and arms — a wet-look gloss characteristic of freshly applied oil. Highlights appear where light hits, enhancing the 3D quality of the skin. Hair also gains a slight sheen.
🗨️ Lab Director: Side by side with the control, the difference is night and day. Instant gravure upgrade. 2 tokens for this effect is a steal.
A02: glistening skin
| seed 1 | seed 2 | seed 3 |
|---|---|---|
![]() | ![]() | ![]() |
Observations: Skin gloss present in 3/3. Compared to oiled body, the intensity and distribution of gloss are very similar. Some images hint at a slightly more dewy gloss with glistening, but this falls within seed-to-seed variation. No meaningful difference from oiled body was confirmed.
A03: shiny skin
| seed 1 | seed 2 | seed 3 |
|---|---|---|
![]() | ![]() | ![]() |
Observations: Skin gloss present in 3/3. Visually nearly identical to oiled body and glistening skin. No notable differences in gloss intensity or distribution. Seed 2 produced a 4-person split composition, but this is a seed trait unrelated to the skin modifier.
A04: body covered in lotion
| seed 1 | seed 2 | seed 3 |
|---|---|---|
![]() | ![]() | ![]() |
Observations: Skin gloss present in 3/3. Similar gloss expression to the other 3 conditions. In seed 2, small droplet-like particles appear on the skin surface, giving a slight “just applied” lotion feel. However, this difference is barely distinguishable from seed-to-seed variation.
Comparison Summary
| Keyword | Gloss Reproduction Rate | Gloss Intensity | Token Count | Characteristics |
|---|---|---|---|---|
| (none) | 0/3 | Matte | 0 | Natural skin |
| oiled body | 3/3 | Strong | 2 | Uniform oil gloss |
| glistening skin | 3/3 | Strong | 2 | Nearly identical to oiled |
| shiny skin | 3/3 | Strong | 2 | Nearly identical to oiled |
| body covered in lotion | 3/3 | Strong | 4 | Slight dewy texture |
Practical Tips
Which One to Use
Conclusion: Any of them works. The difference between the 4 keywords is negligible in practice. Choose based on these criteria:
- Token efficiency →
oiled bodyorglistening skin(2 tokens) - Dewy texture →
body covered in lotion(4 tokens, though the difference is subtle) - Semantic intent → Choose based on the situation (poolside → glistening, massage → oiled, skincare → lotion)
Relation to Existing Findings
In our See-Through Transparency Test, we confirmed that wet specifications affect hair and clothing as well. In contrast, oil/gloss keywords like oiled body affect only the skin, with no observed side effects on clothing or hair. When you want to add skin gloss without changing the outfit, oil-type keywords are more appropriate than wet-type ones.
🗨️ Lab Director: Honestly, the lack of difference almost made this article a bust, but “no difference” is still valuable info for a test article. Just go with oiled body and call it a day.
