30 or Older? Plant-Based Peptides for Skin Can Help You Age Radiantly

Explore the benefits of plant-based peptides for the skin + product recommendations to age beautifully.


Fine lines and wrinkles are inevitable as we age, but the first time we see them on our own face it can come as a shock. In a culture that celebrates youth, it may be an unwelcome surprise. But we can help shift that culture by giving our skin appropriate care as it matures — it’s one way to show the world we’re worthy of top-notch treatment no matter our age. In this post, I’ll explore three products with plant-based peptides for skin at 30+ and two more as a bonus for those on the cusp of 50. But first, I’ll explain how peptides can help your skin continue to glow naturally — revealing your radiance at any age.

Tapping Into The Benefits of Peptides For Skin

Peptides are the amino acids that combine to make proteins in your skin. You’ve heard of collagen? Well, that’s made of polypeptide chains. (If you aren’t familiar with collagen, I’ll do a quick review below.) 

Studies have demonstrated that peptides provide numerous benefits for the skin.  These benefits include:

  • The inhibition of aging-related enzymes, including elastase, collagenase, tyrosinase, and hyaluronidase
  • Antioxidant, antimicrobial, and anti-inflammatory actions
  • Protection against damage when applied topically or ingested

By applying peptides to the skin, you ensure your body has the materials it needs to make collagen, keeping your skin plumper, firmer, and more radiant. And you get some added protection from the daily damage of inflammation and oxidative stress. 

Collagen: Structural Support Stronger Than Steel

Collagen creates structural support throughout your body. Gram for gram, the collagen in your skin, tendons, and bones — Type I collagen — is stronger than steel. Without it, blood vessels, tendons, and skin would be very fragile. 

Your body makes its own collagen, but production decreases as we age. That’s one of the reasons our skin gets wrinkles. Collagen density begins to decline around age 30, at a rate of 1-1.5% each year. We do have some control over that loss by protecting against damage that degrades collagen. And certain products, such as those with peptides, can support collagen production.

Why Marine Algae?

With protein content of up to 47% of their dry weight, marine algae are gaining recognition as a sustainable source of bioactive peptides

Algae are rich in proteins, amino acids, vitamins A, B, and C, and elements including copper, iron and zinc. All of those components aid hydration, firming, and luminance. Many species also contain compounds that protect skin and, in turn, keep it looking youthful. 

Exposed to sunlight all day, marine algae have had to evolve innate protections against damage from UV light. Those compounds — a range of pigments, polysaccharides, phenol, lipids, and proteins — have been shown to protect our skin from oxidative damage as well. 

A review of scientific studies found that algal extracts have the following actions:

  • antioxidant
  • anti-inflammatory
  • anti-pigmentation (evening dark patches of skin)
  • anti-aging
  • anticancer

Algae’s antioxidants play an underlying role in all of the above. That’s because UV-induced oxidative stress contributes to inflammation, melanin-pigment production, aging, and DNA damage that can lead to cancer. By neutralizing free radicals and preventing oxidative damage — especially the accumulation of reactive oxidants, sometimes called reactive oxygen species or ROS — we prevent the eventual repercussions of it too.  

Brown and red algae have, thus far, shown the greatest potential for human use. That said, most algae possess similarly beneficial compounds. 

Age-Corrective Solutions For Skin

The products I recommend below incorporate the benefits of collagen, algae, and peptides for skin. They are geared towards those 30+ who want to slow down the loss of collagen and hyaluronic acid. (Three are part of a collection with special pricing, and the last two are bonus mentions.)

Is anyone else getting the idea that these

products would be a great alternative to botox and fillers? There’s no shame in choosing those options but I have committed to an all natural route. I’m thrilled with the Marine Flower Peptide collection for that reason!

Speaking of which, all of the products are from Eminence Organics’ Marine Flower Peptide Collection. This skin care line has uncompromising standards for quality, effectiveness, and ethical production. 

Marine Flower Peptide Eye Cream 

This rich eye cream reduces visible signs of aging, hydrating the delicate skin around your eyes to minimize the appearance of wrinkles, puffiness, and dark circles.

The formula contains botanical peptides derived from rice protein, and red algae extract with vitamins, minerals, and amino-acids. Botanical hyaluronic acid from beet root smooths and plumps skin, preventing water loss to help maintain long-lasting hydration and minimize the appearance of fine lines and wrinkles. 

The eye cream also contains Eminence Organic’s unique Smart Collagen+ Complex, blending:

  • Botanical collagen from yeast, which has a smaller molecular structure than animal-derived collagen, making it more recognizable to skin
  • Marine algae to increase firmness and bring long-lasting hydration
  • Bulbine leaf, which activates type 1 collagen, according to Eminence

For best results, apply to the entire eye area twice daily, patting gently with fingertips until fully absorbed. Leave on.

Marine Flower Peptide Concentrate

This cream gel acts as a plumper and filler, thanks to the brown algae. Suitable for all skin types, this lightweight formula helps skin look firm and targets visible signs of aging, giving a revitalizing boost that reveals smooth, more supple-looking skin. 

It contains botanical peptides from rice protein to reduce the appearance of fine lines and leave the skin looking energized, and blue-green algae extract, a natural retinol alternative that reduces the appearance of wrinkles without harmful side effects. Finally brown algae extract (from Pelvetia canaliculata) lends skin a firm, supple appearance.

To use, apply 2-3 pumps to cleansed skin once or twice daily. Temporary, mild tingly is normal. Leave on. Follow up with a moisturizer.

Marine Flower Peptide Lip Serum

Like the concentrate, the lip serum plumps and fills with the help of brown algae (Padina Pavonica this time). Reach for this silky serum to reveal smoother, plumper-looking lips while improving the appearance of fine lines and wrinkles in the lips and surrounding area. 

In addition to the brown algae extract, this formula derives its peptides for skin from rice protein to reduce the appearance of fine lines and leave lips looking energized. Botanical collagen from yeast helps give skin structure, working in tandem with the botanical hyaluronic acid, which binds to water to smooth and plump the skin. Brown algae extract (from Padina pavonica) helps the skin look firm, elastic, and hydrated.

To use, dispense a small amount of product and use the oval tip applicator to massage the serum into lips and surrounding area. Leave on, and reapply as often as needed. You can wear this on its own or under a lip balm or lipstick.

For Radiant Skin at 50 and Beyond

While the collection above is for those 30 and older, the two products below were formulated for clients age 50 and older who may already be experiencing a loss of collagen in the form of deep lines and wrinkles.

Marine Flower Peptide Night Cream 

This rich, velvety overnight essential is formulated specifically for delicate, crepey skin. Lock in moisture and smooth, hydrate, and tone while you sleep. Botanical peptides from rice protein and from the superfood sacha inchi give skin a firmer, lifted appearance, minimizing wrinkles. Blue-green algae extract acts as a natural retinoid-alternative to further minimize the look of wrinkles.

For best results, apply a layer over the entire face, neck and décolleté area and leave on. For extra hydration at night, apply a light layer of the Rosehip & Lemongrass Repair Balm on top.
