Review: Trinny London – Plump Up: Peptide HA Serum

Where to purchase: The Trinny London Website: HERE.

Price: £65 / $78

Volume: 30ml

Made in: United Kingdom

What is it?: A peptide-containing serum that works to boost the skin’s collagen in order to plump up the skin and thereby reduce the look of fine lines. Hyaluronic acid is added to also help plump the skin and provide hydration while being lightweight.

Aims to: Plump up the skin + make it bouncy + firmer. It targets dehydration, fine lines + skin-sagging.

Supposedly Good for: All Skin types, even Sensitive.

What I think: I would agree. Dehydrated Skins and even Oily Skins could use this as it’s not thick or heavy, and it’s hydrating.


Vegan?: Yes

Cruelty Free?: Yes

How long does it last after opening?: 12 Months.

pH: Not stated.

Packaging: Plastic tube with an inner tube. You twist the bottom and this inner tube pops up, then you can pump product out. This serum is slightly gloopy so the product does sort of fall out (I must wipe the tip to remove excess product).

Note: You can get refills to save on waste! LINK


Directions: Apply one pump onto the face and then a second pump on both the neck and décolleté (both in the AM and PM) after cleansing and exfoliating.

Note: The brand states this can be mixed in with a moisturiser and/or foundation for a hydration boost.

How I use it: I apply this after toning and right before a cream. If I am using another watery serum, I will apply that first before applying this. I prefer to use this in the PM to avoid any potential balling up with my SPF in the AM. I did take the brand’s advice about mixing this into a moisturiser which I really like as it reduces the potential balling up of this product.

Key Ingredients: 1. Palmitoyl Decapeptide-21 + Zinc Palmitoyl Nonapeptide-14 both make up a Peptide Complex called ”Renaissance”, This complex is meant to ”regenerate, rebuild and redensify” the skin’s tissues. 2. Hexapeptide-9 is also included; a well-ageing peptide meant to reduce the length and depth of wrinkles.

Other Key Ingredients: Hyaluronic Acid (Hydrating + Plumping) / Sucrose (Soothing) / Betaine (Hydrating + Moisturising) + 3 types of Xylitol (Hydrating).

Note: The other peptides included are skin conditioning, hydrating and plumping.

Full Ingredients: Aqua (Water), Glycerin, Pentylene Glycol, Sodium Hyaluronate, Betaine, Hydrolyzed Wheat Protein, Oligopeptide-78, Palmitoyl Decapeptide-21, Zinc Palmitoyl Nonapeptide-14, Hexapeptide-9, Decapeptide-21, Oligopeptide-1, Xylitylglucoside, Anhydroxylitol, Xylitol, Sucrose, Plankton Extract, Glucose, Lecithin, Butylene Glycol, Hydroxyacetophenone, Sodium Hydroxide.

NOTE: The Incidecoder have a full ingredient breakdown HERE

Texture: This is a gloopy gel that almost looks like snail-mucin’s texture the way it drags and almost feels slimy on the skin. But that does mean that this is nicely hydrating and feels smooth and is easy to apply onto the skin.

Sticky?: If I add too much; yes.

Greasy?: No.

Balls up?: 1. If I add to much; it might. If I apply an oil (oily product) on top: yes.

  • As you can see this is a transparent gel. When spreading the product, it is very hydrating and dewy on the skin.

You can see how hydrating and shiny this look.


Product Swatch: No Product (Left) vs No Product (Right):

Does this Sting if the Skin has been Irritated / Sensitised by Shaving/Heavy Retinol Use?: Yes.

Summer or Winter?: Can be used all year-round.

Layerable?: It depends how much product you add. And also, this will ball up under oils (or heavily-oiled products).


Video Swatch:

  • As you can see, this is lightweight and not greasy. this does have an initial stickiness/tackiness to it. That’s why I prefer mixing this in with a moisturiser, which helps.

Fragrance?: Fragrance + EO Free (doesn’t smell of anything either).

Good Under Makeup?: I wouldn’t try it in case it balls up.

How long have I been using this?: 3 Months.

Will I use until Completion?: I still find this hydrating and I like the inclusion of peptides, so yes.

How Long will that take?: 2-3 Months.

The Effect?: Immediately: Hydrated skin! This fills in those fine lines due to the hydrating and thick texture of this product. Long Term: This has overall helped with my skin’s hydration levels. No huge difference with elasticity and plumpness, but this definitely has helped with hydration (which is what I expected from this product!).

What I like:

  • Fragrance + EO Free
  • Airtight, easy-to-use and travel-friendly packaging
  • Hydrating Formula
  • Not greasy
  • Didn’t irritate or worsen my skin

What I don’t like:

  • A bit thick, sticky and gloopy (especially if I add to much)
  • Potential to ball up (I recommend mixing this in with a moisturiser)

Overall Rating and Conclusion: 3.9 / 5 – I like the inclusion of Hyaluronic Acid and especially the Peptide Complexes added to help with extra hydration and plumping of the skin. I haven’t seen the most drastic results, but this does hydrate the skin (the feeling doesn’t immediately disappear). I’m not the biggest fan of the texture and its gloopiness and slight stickiness and potential balling up I’ve experienced with it however. If I mix it in with a moisturiser though, it’ s been good to use! If you like thick-gel hydrating serums, then you could enjoy this! And the addition of peptides makes this a little more exciting than a basic Hyaluronic acid serum.

My Skin Type: I am acne prone and have slightly dehydrated combo skin. My skin is usually tight where the cheeks and eye area is and the outer parts of my face. My T zone is oily. My skin isn’t a fan of thick/heavy formulas so I opt for lightweight formulas to prevent it from clogging up. My skin doesn’t like essential oils either and I try to avoid fragrance when I can.
