What a 62-Year-Old Nutrition Coach Uses for Healthy Aging: 7 Reasons Diane Puts Salmon on Her Plate and on Her Skin

She knows what to eat for healthy aging. This is what she puts on her skin, and why she almost sent it back.

Salmon on your plate gives your body protein, omega-3s and B vitamins. Salmon PDRN on your skin does something different: it’s studied for its role in supporting collagen. SPRKL pairs it with niacinamide, panthenol, Centella asiatica and hyaluronic acid in one serum made for the thinner, drier skin that comes after menopause.

Meet Diane

Certified Transformational Nutrition Coach · Wellness creator for women 45+

Diane Ruggiero has spent years coaching women over 45 to feel vibrant again. Her approach looks at mind, body and soul, and it comes down to one simple rule: what you put on your plate and what you put on your skin both matter. So when she reviews a skincare product, she reads the ingredient list the same way she reads a food label.

Diane also knows what a hard season looks like. A year ago, she was in the middle of treatment for cervical cancer. Today, she’s focused on getting stronger, and on showing other women that life after something that difficult can still be full and hopeful.

She doesn’t have patience for hype, and it shows in how she talks about skincare. She went into this review skeptical, and she’s upfront about what she noticed and what she won’t promise.

“So much can change in a year.”— Diane Ruggiero

Diane’s story is shared with her permission. Diane is a nutrition coach, not a medical doctor, and nothing on this page is medical advice. SPRKL PDRN Serum is a cosmetic product and played no part in her treatment or recovery.

1. No Needles, No Surgery, No Shelf Full of Products

Many women over 50 feel stuck between two options: spend hundreds on injections and procedures, or keep buying cream after cream that never quite works. Diane had been there. A healthy routine works best when it’s simple: a few things that work, done every day. SPRKL gives you a third option. No needles, no surgery, no downtime. Just a few drops a day.

Each bottle pairs PDRN with hyaluronic acid for hydration, niacinamide for an even-looking tone, Centella asiatica to calm the look of redness, and panthenol to support your skin barrier. That’s five key ingredients you’d normally buy as separate products, in one simple step.

“I have bought so many serums that promise the moon, and they have done absolutely nothing.”

2. The Salmon PDRN Is There for a Reason: Collagen Loss Speeds Up After Menopause

Research shows women can lose up to 30% of their skin’s collagen in the first five years after menopause, which is why skin can start to feel thinner, drier and less springy.¹ The ingredient that made Diane hesitate is the one doing the heavy lifting. PDRN has been shown in lab studies to stimulate the cells that produce collagen.⁴

Salmon is a staple of healthy eating for its protein and omega-3s. But PDRN, the DNA fragments taken from salmon, is broken down during digestion like any food, so eating salmon doesn’t put PDRN on your skin. Applying it does.

SPRKL pairs it with hyaluronic acid for hydration and vitamin B5 to help skin hold on to moisture, so skin feels softer, plumper and more resilient.

“When I heard this serum was made with salmon PDRN, I almost sent it back before I even opened it.”
Diane Ruggiero

3. It Helps Protect Your Skin Barrier Instead of Sitting on Top

Many products for mature skin only sit on the surface, leaving skin that still feels dry and tight as the day goes on. SPRKL contains niacinamide, which supports your skin’s natural barrier, and panthenol, which helps draw in moisture and reduce dryness.

Both come from vitamins found in healthy foods like salmon: niacinamide is a form of vitamin B3, and panthenol is provitamin B5. Together, they help your skin hold on to hydration instead of losing it, for skin that feels softer and more comfortable without a heavy or greasy feel.

“If you’re tired of serums that just sit on your skin, this one feels different.”
Diane Ruggiero

4. It’s Gentle and Made for Everyday Use

The texture is the first thing Diane noticed, and it’s by design. The best healthy habit is the one you’ll actually stick to, and SPRKL is made to be pleasant enough to use every single day. It has no artificial fragrance, is non-comedogenic, and is built on well-studied ingredients like PDRN, niacinamide, Centella asiatica and panthenol, chosen for gentleness.

Every batch is made in a certified facility to consistent quality standards. It suits most skin types; if yours is sensitive, patch-test first.

“It’s not watery, it’s not sticky either. It goes on super, super smooth.”
Diane Ruggiero

5. It Helps Bring Back the Glow That Collagen Decline Quietly Takes Away

As estrogen drops, skin can lose some of its natural plumpness and glow, and a dull, tired look settles in. Heavy creams and makeup often make it worse. Drinking water supports hydration from within, and SPRKL’s hyaluronic acid adds hydration on the outside.

SPRKL’s Centella asiatica helps calm the look of redness that can mute your glow, while PDRN supports your skin’s overall quality. The result is skin that looks brighter, smoother and more radiant, fresh rather than flat, with nothing greasy left behind.

“It feels cooling, actually, and it sinks in nice and fast. It has no greasy film.”
Diane Ruggiero

6. It Keeps Supporting Your Skin Over Time, Not Just at First

Collagen loss doesn’t pause on its own, and without ongoing support, skin can settle into a thinner, less-firm state. That’s why a serum you actually enjoy using matters. Just like with nutrition, results come from consistency, not one good week.

Used morning and night, PDRN keeps working over time to support the appearance of firmer, healthier-looking skin, so the results you’re working toward have a better chance of lasting.

“What surprised me is I actually reach for it in the morning and at night.”
Diane Ruggiero
