5 things to know about crepey skin on your arms, neck and chest
What it is, where it shows up first, and how Signal Synq works on it.
-
Crepey skin isn't only dry skin.
Thin, crinkled, papery texture shows up when skin renews more slowly, loses some of its structure and holds less water. Lotion helps with the water. It doesn't do much about the other two.
-
It often shows up below the jawline first.
Neck, chest, arms, hands and knees. It can start at 35 or at 65, and it can show up fast after a lot of weight loss.
-
Signal Synq works on all three at once.
Vitamin A (retinyl linoleate) for renewal. Plant-derived PDRN, from algae, not salmon, for recovery. Peptides for the structure behind firmness.
It's all in a hydrating base, so it replaces your lotion. You feel it tighten when you put it on. Texture changes over weeks.
-
One treatment for face and body.
Most serums stop at the jawline. Most body lotions only hydrate. Signal goes on your face, neck, chest, hands, arms and body. The 9 fl oz size is made for body use.
-
Each ingredient has its own study.
- Vitamin A: 136% more reduction in wrinkle size than placebo after 8 weeks. Supplier split-face study, 24 people ages 22–55.
- PDRN: 8.4% average lift on the neck and chest after 28 days. Supplier study, 32 people age 50+, at the same 2% Signal uses.
- Peptides: 34% less wrinkle density after 2 months. Supplier study, 24 women ages 42–66, at the same 2% Signal uses.
These are studies of the individual ingredients, not of finished Signal Synq.
THIS IS WHAT
WE MEAN.
Jen, Urthy's founder, on her own skin. Phone photos against the same wall in the same light, bare skin, no retouching. Zoomed in so you can see the texture, not the face.
The fine cross-hatch between the horizontal lines is where crepey texture lives. At Day 21 it reads smoother and less papery. The deep horizontal lines are still there.
The etched, crinkled texture across the cheek and beside the mouth is visibly softer and the surface looks plumper. Age spots essentially unchanged — this isn't a brightening routine.
Same side, same angle. Fine lines fanning from the nose toward the jaw look shallower; skin tone reads more even. The smile line is still there — as expected.
Left forearm: regular lotion. Right forearm: Signal. Same day, same person. This is the immediate tightening you can feel — the long-term actives work underneath it.
Founder's personal photos, not a clinical study. Day 0 photos taken late August 2026, Day 21 photos 9/16/26. Routine for those 21 days: Signal Synq™ Hydrating Serum, Clerra and Ekoa Longevity Oil, morning and night. Arm photos taken the same day: Signal on one forearm, regular lotion on the other. Individual results vary.
WHAT PEOPLE ARE SAYING.
“I have been looking for a product that helps my body skin as well. I've been struggling to find anything that keeps my skin not dry and crepey. I was so happy to have found this! I've only been using it for a week now and its amazing. I can tell a difference immediately in the tightness of my skin and overall health and I don't get dry after using this. It's really been a life saver. Can't wait to see what my skin looks like after a. month!”
“Love the difference in my skin and neck. More hydrated, smoother and more even.”
“I believe the skin on my thighs is a little less crepe appearing. I have had no problems with the product. I have used it on my face and neck and I have not had any issues with my rosacea.”
WHY I CALLED IT
SIGNAL.
Under two minutes, in my own words — what skin stops doing over time, why Signal is built for your face and the skin below it, and what vitamin A, PDRN and peptides are actually there to do.
APPLY AFTER
CLEANSING.
Signal is a leave-on treatment. Smooth 1–2 pumps over clean skin, morning and night — face, neck, chest, hands, anywhere skin feels thinner, drier or less firm. Layer oil or balm over it if you want more.
Signal is your hydrator — there's no separate moisturizer to buy. It contains vitamin A as retinyl linoleate, a gentle form: if your skin is new to vitamin A, start every other night for two weeks. Give it a full 30 days.
