DMAE

A prescription firming gel studied to smooth and tighten the look of fine lines and aging skin, from a compound the body makes naturally.

Good to know

DMAE is related to choline, a building block of acetylcholine, the signaling molecule that tells muscles to contract. Researchers think that signaling may be part of why it may create a firmer, tighter-looking appearance over time.1

Concentration matters. Our formula uses 3% DMAE alongside hyaluronic acid for hydration and alpha lipoic acid for antioxidant support.1 5 6

What DMAE may support

DMAE has been studied for both an immediate tightening effect and changes that may build with consistent use, making it different from ingredients focused only on hydration or surface texture.
May smooth the look of fine lines and wrinkles.1
Studied for a firming, tightening skin effect.2
May support skin quality with regular use.3
Evidence is confined to small studies and is mostly cosmetic

How DMAE works

DMAE is thought to firm skin by supporting the tone of the tissue beneath it.1

DMAE benefits

What DMAE may support for skin, with the (limited) evidence behind each.

Fine lines

May smooth forehead and eye‑area fine lines. Human studies.1

Firmness

Studied for an acute skin‑firming, tightening effect. Human studies.2

Skin quality

A formulation study found improvement in skin appearance. Human study.3

Lip & contour

Beneficial trends for lip shape and fullness. Human studies.1

Skin structure

Supports dermal thickness. Animal study.4

Made by the body

DMAE occurs naturally in the body and in fish.

What we still don’t know

We believe in full transparency. Here’s where DMAE’s evidence falls short.

Thin evidence

DMAE’s skin evidence is limited, and some findings are trends.

Compounded Rx

Our DMAE gel is a compounded prescription, not FDA‑approved.

Not for pregnancy

DMAE isn’t for use during pregnancy or breastfeeding.

Clinician-guided skincare, personalized to you

DMAE Firming Gel offers 3% Rx-strength DMAE, the level actually used in published research, compounded by a US-licensed pharmacy, and supported by expert-guided care.1

Frequently asked questions

01 Is DMAE FDA‑approved?

No. DMAE is used in cosmetic skincare, and AgelessRx’s compounded DMAE gel is a prescription that isn’t FDA‑approved. A provider decides whether it’s right for you.

02 What is DMAE?

DMAE (dimethylaminoethanol) is a compound your body makes and that’s found in fish like salmon. In skincare it’s studied for a firming, tightening effect on the skin.

03 How strong is the evidence for DMAE?

Honestly, it’s limited. A cosmetic-dermatology review and a few small human studies support firming and fine-line benefits, and some results are trends rather than definitive. We describe DMAE in measured terms for that reason.

04 What should I expect with DMAE?

Skincare results are gradual. Many people track firmness and fine lines over weeks to months, and results vary from person to person.

05 Are there side effects of DMAE?

Some people notice itching, burning, redness, or peeling, which often ease over the first few weeks. DMAE can increase sun sensitivity, so daily SPF is recommended.

06 Who should not use DMAE?

It isn’t for use during pregnancy or breastfeeding. A provider reviews your health history before prescribing.
