Conclusion
- “milf” affects body type more than age (breast size increase, curvier figure)
- “mature” = “mature woman” — stable age increase to early-to-late 40s
- “older woman” overshoots to 60+, making it unsuitable for targeting 30–40 year olds
- “mother” induces a parent-child composition — not suitable for generating single subjects
- Combining with age specifications (32yo, 40yo, 45yo) allows you to adjust the effect
What This Article Covers
- How milf / mature / mother / older woman affect apparent age and body type
- The standalone effect of age specifications (32yo, 40yo, 45yo)

Base Prompt
Experiment 1: Standalone Keyword Comparison
Condition A: Baseline (no age specification)
Observations
Late 20s to early 30s appearance. Natural makeup. No wrinkles or nasolabial folds.
Condition B: milf (1 token)
Observations
Compared to A, breast size is increased. Body type shifts toward a curvier figure. Facial age shows little change from A. The prominent effect is increased breast size and a more curvaceous body type rather than an age change.
Condition C: mature (1 token)
Observations
Apparent age increases to early-to-late 40s. Eye wrinkles and nasolabial folds are visible. Outfits shift toward more formal attire. Reliably effective for age increase.
Condition D: mother (1 token)
Observations
2/3 images increased to 2 subjects (parent-child composition). “Mother” induces a mother-child context that breaks single-subject consistency. Not suitable for generating a single subject.
Condition E: older woman (2 tokens)
Observations
Apparent age jumps to 60+. Gray-streaked short hair, prominent facial wrinkles. Massively overshoots the target age range.
Condition F: mature woman (2 tokens)
Observations
Minimal visual difference from C (mature). Essentially the same effect.
Experiment 2: Combined with Age Specifications
Condition G: 32yo + milf
Observations
Similar curvier body type to B with increased breast size, but 32yo keeps the facial age in the early 30s. Age increase is suppressed.
Condition H: 32yo + mature
Observations
Largely early 30s with 32yo, younger than C alone. However, 1/3 shifts toward 40s. The age increase from mature is not completely offset by 32yo.
Condition I: 32yo baseline
Observations
Little difference from A.
Experiment 3: Comparison with Direct Age Values
Condition J: 40yo
Observations
Early-to-late 40s appearance. Eye wrinkles and nasolabial folds increase.
Condition K: 45yo
Observations
Further age increase from J, appearing late 40s to 50s.
Condition L: 40yo + milf
Observations
Apparent age impression is somewhat older than J alone (40yo). The combination of 40yo and milf shows a tendency toward further age increase.
Cross-Comparison
Standalone Keyword Comparison (baseline / milf / mature / older woman)
| Seed | Baseline (A) | milf (B) | mature (C) | older woman (E) |
|---|---|---|---|---|
| 42 | | | | |
| 123 | | | | |
| 789 | | | | |
milf affects body type (breast size) more than age. mature produces 40s-equivalent aging. older woman overshoots to 60+.
Age Specification Comparison (32yo / 40yo / 45yo)
| Seed | 32yo (I) | 40yo (J) | 45yo (K) |
|---|---|---|---|
| 42 | | | |
| 123 | | | |
| 789 | | | |
32yo shows little difference from baseline. 40yo increases wrinkles and nasolabial folds. 45yo increases age further.
milf Combination Comparison (milf alone / 32yo+milf / 40yo+milf)
| Seed | milf (B) | 32yo milf (G) | 40yo milf (L) |
|---|---|---|---|
| 42 | | | |
| 123 | | | |
| 789 | | | |
milf alone and 32yo milf have similar body types; 40yo milf adds age increase.
Key Findings
Standalone Keyword Effects
| Keyword | Primary Effect | Apparent Age | Notes |
|---|---|---|---|
| milf | Body type change (larger breasts, curvier) | Little change from A | Body type change is primary, not age |
| mature | Age increase | Early to late 40s | Equivalent to mature woman |
| mother | Induces parent-child composition | — | Unsuitable — produces 2 subjects |
| older woman | Major age increase | 60+ | Excessive for targeting 30–40 age range |
Combined with Age Specifications
- 32yo + milf: Fixes age in the 30s while getting a curvier body type. Most practical combination
- 32yo + mature: Mostly kept in the 30s, but 1/3 shifts toward 40s. mature’s age increase is not fully offset
- 40yo + milf: Apparent age tends to be somewhat older than 40yo alone. Use when targeting late 40s+
Direct Age Value Specifications
- 32yo: Little difference from baseline (A)
- 40yo: Early-to-late 40s. Similar aging effect to mature
- 45yo: Late 40s to 50s. More reliable age increase than 40yo
