Image Analysis Report
## A) Image QA and choice
**Candidate images**
1) **{jobId}_white_center_input.jpg (visible/white light)**
- **Focus:** good (skin detail and pores visible); **noise:** low
- **Exposure:** slightly hot on T‑zone with **strong specular glare** (forehead + nasal bridge) suggesting surface oil; may *inflate texture/pores* detection in bright zones and *hide spots* under glare.
- **Framing:** forehead, chin, and jawline visible; mild tilt but largely centered.
- **Makeup/oil:** no makeup seen; **oiliness present** (shine).
**Selected primary visible:** **{jobId}_white_center_input.jpg**
- Best overall sharpness and full-face framing for visible metrics.
- Despite glare, it retains usable contrast for spots/wrinkles/pores.
2) **{jobId}_uv_center_input.jpg (UV / ~365 nm)**
- **Focus:** fair-good; **noise:** moderate (blue channel noise typical of UV imaging)
- **Exposure:** generally even; some vignetting at edges; overall usable contrast for UV-absorbing spots and fluorescence.
- **Framing:** forehead and chin in frame; face centered; eyes closed (OK).
**Selected primary UV:** **{jobId}_uv_center_input.jpg**
- Only UV candidate and sufficiently even exposure for UV spots + porphyrins.
**Estimated Fitzpatrick type (best-effort):** **III–IV (est.)** based on visible pigmentation and tanning response appearance (low confidence).

## B) Eight-metric table (VISIA-style; visible + UV only)
All size/area are **IPD-normalized** (relative to a standardized face mask). Intensity is **0–100 (within-image normalized)**. Counts are best-effort approximations from the single center view.
| Metric | Modality used | Result (overall) | Primary locations | Confidence / limitations |
|---|---|---:|---|---|
| **Spots** | Visible | **Count:** ~45 (est.) • **Area:** ~3.8% (est.) • **Intensity:** 38/100 | Cheeks > forehead > nose | **Med.** Glare on forehead/nose can mask true contrast lesions. |
| **Wrinkles** | Visible | **Line length index:** 42/100 (est.) • **Depth/contrast:** 35/100 (est.) | Forehead lines (mild), under-eye fine lines | **Low–Med.** Eyes closed reduces crow’s-feet visibility; lighting not raking. |
| **Texture** | Visible | **Roughness score:** 58/100 (est.) | Cheeks and nose | **Med.** Shine can exaggerate micro-contrast in highlights. |
| **Pores** | Visible | **Density:** 62/100 (est.) • **Area:** ~2.6% (est.) | Nose + medial cheeks | **Med.** Oil/glare may enlarge apparent pore openings. |
| **UV spots** | UV | **Count:** ~120 (est.) • **Area:** ~9.5% (est.) • **Intensity:** 55/100 | Cheeks + nose bridge > forehead | **Med–High.** UV image is reasonably even; still some edge vignetting. |
| **Brown spots (proxy, est.)** | Visible (melanin-weighted proxy) | **Count:** ~65 (est.) • **Area:** ~5.0% (est.) • **Intensity:** 44/100 | Cheeks, lateral face | **Low–Med.** No RBX/cross-pol; redness/shadows can be misclassified. |
| **Red areas (proxy, est.)** | Visible (hemoglobin-biased proxy) | **Area:** ~2.2% (est.) • **Intensity:** 33/100 | Nose (mild), perinasal/central cheeks | **Low.** Very sensitive to illumination + surface shine; not diagnostic. |
| **Porphyrins** | UV fluorescence | **Count:** ~80 (est.) • **Intensity:** 60/100 | Nose and medial cheeks | **Med.** Fluorescent speckling is visible; some may be sensor noise/dust. |

## C) Regional breakdown (area% = % of standardized face mask; intensity 0–100)
| Region | Spots area% | UV spots area% | Pores density (0–100) | Texture (0–100) | Red areas area% (proxy) |
|---|---:|---:|---:|---:|---:|
| **Forehead** | 0.7% | 2.0% | 48 | 52 | 0.2% |
| **Periorbital** | 0.3% | 0.6% | 30 | 45 | 0.2% |
| **Cheeks** | 2.2% | 5.5% | 66 | 62 | 1.1% |
| **Nose** | 0.4% | 1.1% | 82 | 60 | 0.5% |
| **Perioral** | 0.1% | 0.2% | 40 | 50 | 0.1% |
| **Jawline/neck** | 0.1% | 0.1% | 35 | 45 | 0.1% |
Notes:
- Visible **shine** is highest on **forehead/nose**, biasing pores/texture upward and masking some spot contrast.
- UV shows widespread **subsurface pigment** signal over cheeks/nose (typical “UV spot” pattern).

## E) Scores and summary (approximations)
### Percentile bands (peerless approximation; for age 41M)
- **Spots (visible):** **25–50**
- **Wrinkles:** **50–75**
- **Texture:** **25–50**
- **Pores:** **25–50**
- **UV spots:** **10–25**
- **Brown spots (proxy, est.):** **25–50**
- **Red areas (proxy, est.):** **50–75**
- **Porphyrins:** **10–25**
### Composite score (0–100)
Interpretation: **higher = “cleaner/less burden”** across measured features.
Using equal weights across all **8 available** metrics: **12.5% each**
- Spots 12.5%
- Wrinkles 12.5%
- Texture 12.5%
- Pores 12.5%
- UV spots 12.5%
- Brown spots (proxy) 12.5%
- Red areas (proxy) 12.5%
- Porphyrins 12.5%
**Composite (est.): 56 / 100**
### TruSkin Age (approx.)
Based on UV spots + pores/texture burden trending slightly “older” than chronological, while wrinkles/redness are moderate:
**TruSkin Age (est.): 44–47** (low–medium confidence; single angle, no VISIA norms)
**Key takeaways (cosmetic; not medical):**
- Primary opportunities: **UV spot burden on cheeks/nose**, **porphyrin activity** (nose/medial cheeks), and **pore/texture prominence** in the T‑zone/inner cheeks.
- Wrinkles appear **mild–moderate** (forehead fine lines; under-eye lines limited by eyes-closed capture).

## F) Plan and tracking
### Targeted plan (12 weeks)
1) **Daily UV protection (highest ROI for UV spots)**
- Broad-spectrum **SPF 30–50** daily; reapply with outdoor exposure.
- Consider tinted/mineral options if visible-light pigment is a concern (proxy-based note).
2) **Pores/texture + porphyrins (nose/medial cheeks)**
- **BHA (salicylic acid) 2%** 3–5 nights/week (adjust for tolerance).
- Gentle cleanser; avoid over-stripping (can increase oil rebound).
3) **Pigment/spot appearance (visible + UV)**
- **Vitamin C (L-ascorbic acid 10–20%)** mornings *or* a stable derivative if sensitive.
- **Retinoid** (adapalene/retinol) nights 2–4x/week, building as tolerated (supports texture and spot turnover).
4) **Redness (proxy; low confidence)**
- Minimize triggers (hot water, aggressive scrubs); consider **niacinamide 4–5%** for barrier support.
### Tracking protocol (to reduce measurement bias)
- Recreate **same distance/angle**, neutral facial expression, **clean/dry skin**, and blot T‑zone to reduce glare.
- Take visible + UV at **baseline, week 6, week 12**.
- Watch for: **UV spots area%**, **porphyrin count**, and **pore density** as the most responsive metrics here.
