SkinCeuticals A.G.E. Interrupter Ultra Serum — 34.6% Flavo-Proxylane Firming Serum for Face & Neck

A Physician-Tested Approach to Firmer, More Sculpted-Looking Skin

A.G.E. Interrupter Ultra Serum is a double-patented firming serum formulated with 34.6% Flavo-Proxylane and Cassia Alata Extract, designed to target visible signs of aging linked to collagen decline and glycation (the process by which sugar molecules can affect collagen and elastin over time). Physician-tested and studied over a 12-week period, the formula is designed to help visibly lift, firm, and tighten the appearance of the forehead, cheeks, jawline, and neck, and is suitable for all skin types and tones.

Why You Should Buy This

Backed by patented, proprietary technology. Flavo-Proxylane at this specific 34.6% concentration is a SkinCeuticals-patented ingredient combination, not a generic firming compound.
Targets a root mechanism of skin aging, not just the surface. By addressing glycation — a lesser-discussed contributor to collagen and elastin breakdown — this serum goes beyond typical surface-level anti-aging approaches.
Multi-zone treatment in one product. Formulated to address the forehead, cheeks, jawline, and neck together, rather than requiring separate products for each area.
Physician-tested credibility. Studied and tested by physicians, lending additional professional credibility to the formula.
Broadly suitable formulation. Tested across all skin types and tones, reducing guesswork about compatibility.

What You Should Use It For

A.G.E. Interrupter Ultra Serum is best suited for:

Adults looking to address visible skin laxity across the face and neck
A firming and sculpting step layered into an existing anti-aging skincare routine
Targeting the look of aging linked to glycation and collagen decline specifically
Consistent daily or twice-daily use over a 12-week period to evaluate visible results
Use alongside daily sunscreen (this serum addresses firming, not sun protection — SPF should be applied separately)

FAQ

What is A.G.E. Interrupter Ultra Serum used for?
It's a firming serum formulated with 34.6% Flavo-Proxylane and Cassia Alata Extract, designed to help visibly firm and lift the appearance of the forehead, cheeks, jawline, and neck, targeting signs of aging linked to glycation and collagen decline.

What is glycation, and why does it matter for skin?
Glycation is a natural process where sugar molecules can bind to proteins like collagen and elastin over time, potentially affecting their structure and contributing to visible skin aging. This serum is formulated with glycation in mind as one contributor to skin laxity.

How long until I see results?
The formula has been studied over a 12-week period for visible firming effects. Individual results and timelines vary.

Are the specific lift and wrinkle-reduction percentages (like "+18% lift" or "-16% wrinkles") verified?
Your original listing cites specific clinical percentages (lift, wrinkle reduction, smoothness, moisture increase). Because these are precise, quantified clinical claims, we'd recommend confirming the exact study conditions and any required disclaimer language from SkinCeuticals' official documentation before publishing them, so the figures are presented with accurate context and match the manufacturer's actual substantiation.

Can this be used on the neck as well as the face?
Yes, the formula is specifically designed to address the forehead, cheeks, jawline, and neck together.

Does this serum replace sunscreen?
No. This is a firming serum and does not provide sun protection. Use a separate broad-spectrum sunscreen daily.

Is this serum suitable for all skin types and tones?
Yes, the manufacturer states the formula has been tested across all skin types and tones.

Who is this serum best suited for?
Adults looking for a physician-tested, patented firming serum to address visible skin laxity across the face and neck, particularly those interested in targeting glycation-related aging specifically.

What our customers say

Love this drink! I miss this with electrolytes (LMNT) and my leg cramps disappear.

IMHO, AG1 is the superior multi-vitamin and pre-and-pro biotic supplement. After a lot of label comparisons and general supplement reading/research, I keep coming back to AG1. It offers a better nutritional foundation than Huel and popular gummy supplements�especially if you add the AG d3+k2 drops (which are sold as a separate liquid for quality-protection purposes).AG1 has helped decrease my appetite (especially in the morning) and increase my energy. For me, it tastes best with 4oz of low-sugar orange juice and 4oz of water. Mixing it with orange juice also supports better absorption of creatine supplements. Fiber supplements should be taken at least 4 hours before or after AG1 to avoid bloating and interfering with its pre/probiotic gut benefits. Pro tip: if you�re unsure whether or not AG1 is right for you, or will work well with your current supplement regime, ask AI to evaluate your supplement strategy.AG1 is worth the money for those who want to invest in their health.

I did a taste test and compared this product AG1 against several of the competing products. This is the best one. This product is superior for several reasons: taste, range of ingredients, and the inclusion of many vitamins. Other green drinks don't contain vitamins, which is one reason why they cost much less. Also, other green drinks taste too vegetal and earthly, an unpleasant taste. AG1 tastes really good, kinda like vanilla or coconut. My only gripe about AG1 is the cost, which seems exorbitant. But if you don't mind paying extra, this is clearly the best product in the category, which I suppose is justification for the high price.

I just kind of bought this on a whim, so I'm not even sure what all effect it was suppose to have. I figured I probably didn't eat quite enough veggies, and for my entire I've regularly digestive issue after dinner (2-3 times a week). It was more expensive than I wanted it to be, but I figured the per serving cost was worth it for knowing what I was getting and having something backed by at least some data.Well, they can charge me whatever they want now. I'll never stop buying this. I haven't had ANY digestion issues in WEEKS. None. I can't fathom what this stuff is doing to/for me to fix a problem I've had, and been to the doctor for multiple times, my entire life. One of the single most effective products I think I've ever purchased in my almost 40 years.It tastes pretty bad and smells even worse, but it mixes really easy, so I just do the 8 ounces and take it like a shot straight out of the shaker.Hard for me to comment on energy level, because that has never really been an issue for me, but I generally think I feel a little better during the day. I'm also sleeping better, which could mean I'm using more energy during the day.I couldn't be happier. Truly a marvel.
