If you’ve been wondering why makeup isn’t sitting right lately, you’re not imagining it. Your makeup doesn’t glide on as smoothly, your foundation settles into fine lines, and that once-dewy finish seems to disappear by midday.
If your routine hasn’t changed but your skin suddenly has, the culprit may not be your makeup, it’s your collagen.
From your mid-20s, your body’s natural collagen production begins to decline by around 1–1.5% each year. This gradual loss reduces the skin’s elasticity, hydration and firmness, all essential for a smooth, even surface.
As collagen diminishes, skin can become thinner, rougher and more reactive, which makes makeup harder to apply and less likely to stay fresh throughout the day.
You might notice foundation collecting around your nose or eyes, powder settling into fine lines, or even makeup that seems to “sit on top” of your skin instead of blending in. These are all signs your skin’s underlying structure is changing, and it needs a deeper level of support.
Collagen is often described as the scaffolding that keeps your skin firm, smooth and youthful. It forms a structural network within the dermis, supporting cell turnover and maintaining hydration. When collagen levels drop, makeup doesn’t sit right because the skin can no longer hold moisture or maintain that silky surface.
Even with good skincare and professional-grade products, if your skin’s internal support system weakens, its outer surface can’t hold onto moisture or maintain that silky texture makeup loves to glide across.
Clinical studies have shown that hydrolysed marine collagen peptides, the same type used in ProPlenish Marine Collagen, can significantly improve skin hydration, elasticity and density.¹ ² ³ One study found that participants taking collagen daily for eight weeks experienced up to a 28% increase in skin hydration, while others reported visibly firmer, smoother skin.
This improvement at a structural level gives your skin back its natural resilience, so makeup once again applies evenly and stays radiant all day.
When makeup stops performing, most people reach for new primers or foundations. While these can help short-term, they don’t address the root cause: the decline of collagen and hydration deep within the dermis.
Topical skincare can smooth and hydrate the surface, but collagen is produced much deeper. It’s made by fibroblast cells in the middle layer of the skin, where topical creams simply can’t reach. That’s why ingestible collagen has become a cornerstone of advanced beauty routines, it supports your skin from within, where firmness and hydration originate.
When you consume ProPlenish Marine Collagen, the bioavailable peptides are absorbed into your bloodstream and stimulate fibroblasts to produce more of your body’s own collagen, elastin and hyaluronic acid. This cellular activity strengthens your skin barrier and boosts moisture retention, creating a naturally plump, hydrated base that makeup loves.
So, rather than masking the issue with heavier products, ProPlenish helps restore the smooth, supple texture you had before your makeup stopped sitting right.
For best results, consistency is key. Adding ProPlenish Marine Collagen to your daily routine is effortless, it dissolves easily in water, tea, coffee or smoothies without affecting taste. Over time, this small ritual has a big impact on your skin’s texture and tone.
Most people begin to notice visible results within 4–8 weeks of daily use: improved elasticity, better hydration, and that renewed glow that makes skin look healthy even before makeup. After three months, the difference is undeniable, foundation applies evenly, blush blends beautifully, and your skin retains that radiant, hydrated finish throughout the day.
It’s about strengthening the foundation beneath your foundation, because great makeup starts with great skin.
If your makeup routine feels suddenly “off,” it’s not that your products have stopped working, it’s your collagen levels quietly declining beneath the surface. The good news? You can rebuild them.
By replenishing collagen daily, you’re supporting your skin’s structure and long-term hydration from within. With time, your skin regains its natural plumpness, fine lines soften, and your glow returns, making every makeup application smoother and more effortless than before.
Your skin deserves more than a quick fix. Start from within with ProPlenish Marine Collagen and rediscover the smooth, glowing canvas that lets your makeup shine.
For makeup that truly glows all day:
Hydrate early. Drink 2–3L of water daily to complement your collagen intake.
Exfoliate weekly. Gentle exfoliation smooths the surface and enhances radiance.
Apply skincare while skin is damp. Moisturiser locks in hydration more effectively.
Add your ProPlenish marine collagen to your morning coffee or smoothie. Consistency is key for visible results.
