How Saecra works
Saecra answers one question: did the thing you started actually work on your face? A new product, a routine, a treatment, a habit. You log it, take a daily photo, and Saecra shows you what changed, measured on your phone.

Your daily photo
Once a day, Saecra guides you to the same distance, angle and light, then takes a quick burst of frames. It takes about ten seconds. Because every photo is taken the same way, a change you see is a change in your skin, not in your bathroom light.
What it measures
Blemishes: every spot is found, circled and counted, and Saecra remembers where each one was, so it can tell old spots from new ones.
Fine lines: on the forehead, around the eyes and along the smile lines.
Dark spots and marks: post-acne marks and sun spots are counted and sized, and tracked as they fade.
Everything is measured on your phone. Your photos never leave it.
What you log
Two taps, whenever something changes: a new product or routine, including the exact ingredient and strength, a treatment like a facial, peel, laser, injectable or prescription, and the things that affect your skin, like sleep, your cycle, diet, alcohol and stress.
What you see
Week by week, Saecra lines up your photos and your log. When something changed, you see it on your own photos, along with what you did before it. When the change is too small to trust, it says so: too early to tell.
What it will never do
It won't diagnose anything, guess your skin age, give you a beauty score, or recommend products or ingredients. It sells nothing but the app, so it has no reason to tell you anything but the truth.
