The only acne app that doesn't sell you skincare

Your skin,
decoded.

Dermenda links your photos, diet, sleep, stress and cycle to find what's actually causing your breakouts — and what's actually clearing them.

No credit card · No product upsells · Your data stays yours

We don't sell skincare

Other acne apps push their own products. We have nothing to sell — so our advice has nothing to hide.

Causal, not correlational

Most apps just count pimples. We surface what's actually triggering YOUR breakouts.

Derm-ready in one tap

Every insight exports to a PDF your dermatologist can read in 30 seconds.

Six pillars. One coherent system.

Built around how skin actually heals — slowly, individually, and with feedback loops.

AI Vision Analysis

Daily guided selfies. We measure lesion count, redness, inflammation, oiliness — per facial zone, over time.

Causal Trigger Engine

Not 'dairy is bad'. We tell you 'dairy correlates with +38% cheek breakouts within 48h for YOUR skin'.

Ingredient Intelligence

Snap any product label. Verdict tailored to YOUR triggers — not a generic comedogenic list.

Adaptive Routine

Your AM/PM routine auto-adjusts when the engine spots something hurting your skin.

Cycle-Sync Forecasting

Predicts hormonal breakout windows so you can pre-treat 3 days before they hit.

Dermatologist Export

One-tap 90-day PDF: photos, trends, triggers, routine. Share with your derm in 7-day expiring links.
