Good Molecules’ Super Peptide Serum?

As a true skincare addict I live for those rare moments when you come across a product that is both affordable and actually delivers; and (for me at least) the Good Molecules Super Peptide Serum* really does fall into this category.

Because among my list of favourite ingredients- vitamin C, AHAs, and retinols- is one which offers perhaps the most immediate results: peptides.


Made up of amino acids, peptides are small molecules in skin cells which help to create collagen and elastin.

While there is some uncertainty about whether peptides in skincare products are small enough to penetrate skin (which is generally designed to keep things out), some dermatologists believe peptides applied directly to the face may send signals to skin cells to create more collagen and elastin- with the result of firmer, more youthful skin.

Good Molecules Super Peptide Serum

I’ve found that peptides have certainly always seemed to make my skin springier and firmer, so when Good Molecules offered to send me some goodies, I jumped at the chance to try their Super Peptide Serum.

Containing multiple peptides- including hexapeptide-8 and copper peptides (as well as some citrus oil for scent), this lightweight serum also packs in glycerin to soften skin.

Fast-absorbing, this works for both morning and evening use, and layers well with my other products- leaving me with skin that feels noticeably firmer.

The Full List of Ingredients

Aqua (Water), Propanediol, Butylene Glycol, Glycerin, Acetyl Hexapeptide-8, Acetyl Octapeptide-3 Copper Tripeptide-1, Bis-PEG-18 Methyl Ether Dimethyl Silane, Phenoxyethanol, Chlorphenesin, Glycereth-25 PCA Isostearate, Polyacrylate, Ethylhexylglycerin, Caprylyl Glycol, Xanthan Gum, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, Thromethamine, Polyisobutene, Citrus Aurantium Bergamia (Bergamot) Fruit Oil, Disodium EDTA, Polysorbate, Sorbitan Isostearate, Sodium Hyaluronate, BHT, 1,2-Hexanediol, Glycine

The Takeaway

I think this serum is ridiculously good value, and for me at least this genuinely delivers on its claims of firmer, smoother skin. It’s also great to note that it is cruelty-free.

The pleasant citrus scent to this is actually caused by essential oil, however, and while I haven’t had any issues, it’s a good idea to patch test this first- particularly for sensitive skin types.

Great for: Peptide fans looking for an affordable, reliable alternative to a current favourite, or anyone wanting to dip a toe into the peptide world without spending too much.

Not-so-great for: Those who don’t like citrus oils, even though there isn’t much in here.

Good Molecules’ Super Peptide Serum is $12/£9.22 for 30 ml, Beautylish
