The Science of Skin Aging: What Actually Works (and What Doesn’t)

Chapter 1: Why “Anti-Aging” Is the Wrong Framework

Dr. Rinde You’ve explained from the jump that anti-aging is the wrong framework. Why is that? I find it very refreshing.

Lily Anti-aging frames biology as something to fight, something to correct, something to reverse or override — and it’s just a losing game. Aging is not a malfunction. It’s a process. It’s a privilege. What actually determines outcomes is whether the underlying systems are supported or stressed. I think of it in terms of health span — the quality of the years that you’re alive. Skin longevity is the same concept applied to skin. It’s your skin span.

Dr. Rinde How does conventional skincare think about skin, versus what you’re describing?

Lily Conventional skincare tends to chase visible fixes — wrinkles, tone, texture. The way I think about skin span and skin longevity, it’s about how well skin maintains its structure, its barrier integrity, its hydration, its pigment balance, and its repair capacity over not months but years and decades.

Chapter 2: The CALM Framework for Skin Longevity

Lily I’ve named my framework CALM. C stands for Collagen integrity — the scaffolding, the structure underneath the skin. If that matrix is depleted, no serum can fake firmness in the long term. A is Antioxidant balance. Skin is constantly exposed to UV and digital light, which generates oxidative stress. If that load isn’t controlled, aging accelerates no matter how good your ten-step routine looks. L is Lipid barrier — ceramides and barrier lipids that determine whether skin can hold hydration and tolerate the actives you put on top. And M is Mitochondrial function — cellular energy. Repair, turnover, and recovery all depend on it.

Dr. Rinde When do we start to see dysfunction in these systems accelerate across the lifespan?

Lily The common wisdom is that you start losing collagen and elastin from your mid to late 20s — roughly 1% per year. It’s gradual but progressive. For women, midlife hormonal changes dramatically accelerate all of it simultaneously.

Chapter 3: How Estrogen Decline Affects All Four CALM Pillars

Dr. Rinde Can you talk about what’s happening when people start seeing shifts in their reproductive hormones and how that affects skin?

Lily Estrogen plays a role in collagen synthesis, lipid production, hydration, antioxidant defense, and repair — all of it. As levels fluctuate and decline — which begins in perimenopause, in the late 30s and early 40s — all four of those systems shift at once. Women are often told this is cosmetic. It’s actually a fundamental biological transition that affects skin function.

Dr. Rinde Have you seen an impact on mental health and wellbeing from people who take an active role in their skin health?

Lily I launched in August and I’m now getting feedback from people who’ve been taking it four months. I guide people to 90 days before expecting visible changes. But I’m starting to hear: my skin tone completely cleared up, my hair is growing. One woman in her 60s had someone ask if she got hair extensions. As people see changes in their skin, nails, and hair, they feel better about themselves — especially women going through perimenopause or menopause who are watching those changes happen and feeling like they have no agency.

Chapter 4: Why a Systems Approach — Not a Hero Ingredient

Dr. Rinde You moved away from single-ingredient solutions toward a comprehensive formulation. Why?

Lily I formulated this for myself. I’m 46 now, was in my early 40s when I started seeing skin and hair changes, and I wanted to understand what actually has human clinical data behind it. I think in terms of human data, dosing, contamination, and ingredient purity. I went through several hundred clinical trials to understand which ingredients have science behind them. Biotin is a perfect example — it’s marketed as a beauty supplement, but there’s absolutely zero evidence unless you’re deficient. Most people aren’t.

Lily I came up with a beautiful cocktail that worked — but it was a bowl of pills I couldn’t get through. I thought: why doesn’t a powder like AG1 exist for skin, with all the right ingredients at all the right doses? I created it for myself. I never meant to become an entrepreneur. But when I brought it to life I thought: this is the future of dermatology. Think of skin longevity like running a house. Structure is the walls, barrier lipids is the roof, antioxidants are the wiring, and cellular repair is the plumbing. If you have a leaky, drafty house, do you fix it by upgrading the sofa? No. It takes multiple inputs working together.

Chapter 5: VERISOL® — Bioactive Collagen vs. Generic

Dr. Rinde Are there myths about collagen you’d like to see go away?

Lily Not all collagen is created equal. You have bovine and marine, and within those categories further breaks down. But the more important distinction is: generic collagen versus bioactive collagen peptides. Generic collagen is protein — amino acid building blocks — and you’re hoping some of it ends up as collagen. There’s no specific mechanism for that.

Lily Bioactive collagen peptides are specific di- and tripeptides — specific amino acid sequences at the right molecular weight to be absorbed and carry through the blood. They have an affinity for fibroblasts in the skin. When fibroblasts sense those sequences, they interpret it as a signal: we lost collagen, we need to make more. That is the mechanism. And collagen doesn’t work in isolation — you need vitamin C to stabilize the helix, zinc and selenium for the enzymatic processes, and mitochondrial energy for the fibroblasts to actually lay down a healthy matrix. Without the full system, results often flatline.

Lily The collagen I use is called VERISOL® — a patented collagen from a German company called Gelita. It’s the only collagen I know of with seven human clinical trials specifically for skin, with real outcomes.

Dr. Rinde Type 1 versus Type 3 — does that matter?

Lily They’re different and formulated for different goals. Gelita makes versions for bones, joints, recovery, and skin. I use their skin-specific formulation. I actually separately take their joint collagen in addition to my daily ATIKA drink, because the collagen in ATIKA is optimized for skin.

Chapter 6: Ceramides vs. Hyaluronic Acid

Dr. Rinde Can you talk about the omegas and lipids of the skin?

Lily The lipid barrier is about 50% ceramides, 25% cholesterol, and 25% other fatty acids. When people talk about hydration, they often say hyaluronic acid hydrates your skin — but mechanistically, that makes zero sense. Hydration is your skin’s ability to keep moisture in. When your lipid barrier is intact, your body retains that moisture — that’s where the hydration, plumpness, and glow come from.

Lily I made a conscious choice not to include hyaluronic acid in my formulation. High-molecular-weight hyaluronic acid — what most mass-market products contain — can’t penetrate the skin’s outer barrier. It sits on the surface and creates a temporary appearance of plumpness. Low-molecular-weight versions can penetrate deeper, but hyaluronic acid is a humectant — it draws moisture toward itself, and in dry environments it can actually pull water out of deeper skin layers and worsen dryness.

Lily What I included instead is Ceramosides™ — a patented ceramide ingredient from France with strong clinical data. It helps replenish your skin’s natural ceramides, repairing the lipid barrier from within. People are seeing improved hydration within two to three weeks. The same ingredient at the same dose also shows strong hair benefits — which is why I’m getting so much hair feedback even though I formulated this for skin.

Chapter 7: Antioxidants, Glutathione, and Hormesis

Dr. Rinde We see glutathione and other antioxidants like alpha lipoic acid in a lot of skin formulations. How are you thinking about mitochondrial and antioxidant support for skin?

Lily Glutathione — great master antioxidant. The problem is you really can’t supplement with it. Your cells don’t have a way to bring it inside where it actually works. IVs, injections, liposomal forms — mostly ineffective. You have to support endogenous glutathione production by supporting the antioxidant system more broadly.

Lily What I’ve done is create the first multi-pathway, multi-antioxidant on the market. We take multivitamins — most of us aren’t deficient but we take them. What we should really be taking is multi-antioxidants, because antioxidants are genuinely hard to get from food at clinical doses. But the antioxidant system in your body works like a network — different antioxidants pass reactive oxygen species to each other, and minerals like zinc and selenium sit inside the enzymes that run those reactions. The full system matters.

Lily High chronic doses of a single antioxidant can actually interfere with the very signaling and repair processes you want. High-dose antioxidant supplements have been shown in some studies to blunt exercise-induced adaptations, likely because a certain amount of reactive oxygen species is needed as a signal for muscle and mitochondrial adaptation. Reactive oxygen species are not only damaging agents — they’re also signaling molecules. Over-suppressing one part of that signal, especially without the balancing nutrients like zinc and selenium that support endogenous antioxidant enzymes, can disturb the redox balance rather than fix it. Balance and context matter very much.

Chapter 8: The Gut-Skin Connection and Holistic View

Dr. Rinde Are you thinking about dietary restrictions, chronic stress, and gut health in your approach?

Lily Yes, because I’m taking a holistic view and it’s all interconnected. You hear people say: I had crazy acne, then I fixed my gut and it went away. Because it’s one mechanism. It’s all connected.

Chapter 9: VISIA Results, Timelines, and What to Expect

Dr. Rinde Can you share a success story that’s made you feel you’re on the right path?

Lily I’ll share my own. When I was 43, I got a VISIA scan — a multi-spectral imaging system used in dermatology that measures wrinkles, sunspots, pores, UV damage, redness, and more, expressed as percentiles against a database of over 250,000 people matched by age and skin type. It’s objective and reproducible — you can measure actual change. I took ATIKA every day for 12 weeks, then rescanned at age 45. Two years older, and I had dramatically fewer wrinkles. The before-and-after scans are on my website. I’ve never done a laser. My topical routine is embarrassingly bare-bones. I’ve had Botox maybe three times in my life. That improvement was purely from this drink.

Dr. Rinde Any precautions people should know about?

Lily The ceramides are wheat-derived, but the allergens are stripped out — it is gluten-free, but worth knowing the source. I also include MCT oil, which is coconut-derived. That’s there to enhance bioavailability of the fat-soluble vitamins — the carotenoids, vitamin D, astaxanthin. They need fat for proper absorption, so I built it into the formula so you don’t have to worry about taking it with food.

Lily If I could leave people with one thing: if you’re seeing changes — in your skin or any organ — your body is not failing you. It’s communicating with you. Changing how you listen could shift the relationship from conflict to partnership.

Dr. Rinde Where can people find ATIKA?

Lily Online at atikawellness.com. I’m also writing articles in the journal section of the site weekly — GLP-1 and skin, ceramides versus hyaluronic acid, glutathione, and more. On social media, @atika.wellness. The content is mostly educational.
