Today’s formulation is a richly moisturizing, cold-processed, Silky Soothing Facial Gel. It was inspired by a La Roche Posay product—their B5 gel. This DIY is definitely more “inspired by” vs. attempting to duplicate their product as I don’t have all the same active ingredients, and I love what I’ve come up with! It’s brilliant for dry, irritated skin, and just the thing to add to your deep-winter skincare routine.

How to Make Silky Soothing Facial Gel

For soothing actives, I’ve blended panthenol (Vitamin B5) and allantoin. Both are unassuming white powders that are fantastic for irritated, dry skin. Panthenol boosts skin elasticity and stimulates regeneration, while allantoin is an approved skin protectant. If you’re wondering why the concentration of allantoin is so low, it’s because I’m aiming to keep it below its maximum water solubility level. Allantoin is only water-soluble to about 0.5%, and it can be shardy and unpleasant if it doesn’t dissolve in formulations—so, I keep my usage rate below 0.5% of the amount of water in a formulation so it has plenty of available solvent. You could notch it up to 0.4% if you wanted to, removing that extra 0.1% from the distilled water.

In addition to the moisturizing goodness from the panthenol (Vitamin B5) and allantoin, we’ve also got two great humectants in here—hyaluronic acid and propanediol 1,3. While these are both low-tack humectants, I have found gels can be tacky, so I’ve included a small amount of dimethicone 350 for improved slip, richer skin feel, emolliency, and reduced stickiness.

I’ve used Polyacrylate crosspolymer-6 (Sepimax ZEN) to gel this product because it creates silky, rich gels; if you don’t have it you could try Aristoflex AVC. If you don’t have that, either, you could try hydroxyethylcellulose, but you’d want to swap the dimethicone 350 for a PEG dimethicone like PEG-8 dimethicone. Since PEG-8 dimethicone is water-soluble we don’t need the pseudo-emulsifying powers of the Polyacrylate crosspolymer-6 (Sepimax ZEN). Whatever you do, please don’t use xanthan gum unless you are a big fan of the texture of boogers 😬

Making this is really easy. The video has a specific order + pre-dispersing the Polyacrylate crosspolymer-6 (Sepimax ZEN™) in the propanediol but honestly… you don’t have to do that. You can just throw everything in a beaker, cover it, wait a few hours, and stir until smooth. Enjoy!

Silky Soothing Facial Gel

34.4g | 68.8% distilled water
10g | 20% low molecular weight 1% hyaluronic acid solution (USA / Canada / New Zealand)
1.5g | 3% Propanediol 1,3 (USA / Canada)
0.75g | 1.5% Polyacrylate crosspolymer-6 (USA / Canada / UK / Australia)
1.5g | 3% panthenol powder (vitamin B5) (USA / Canada)
0.15g | 0.3% allantoin (USA / Canada)
1.5g | 3% dimethicone 350 (USA / Canada)
0.2g | 0.4% Liquid Germall Plus™ (USA / Canada)

Weigh all of the ingredients into a beaker. Cover the beaker and leave everything to hydrate and dissolve for a few hours—the mixture should appear clear, though it will likely look a bit lumpy.

Stir until smooth—a small wire whisk is useful for this step. I used my mini mixer.

That’s it! I packaged my Silky Soothing Facial Gel in a 50g (1.76oz) frosted soft squeeze tube from YellowBee. Watch the video to see how I did it! You’ll need a syringe (USA / Canada).

To use, smooth a pea-sized amount (or more—it’s up to you) across your skin after cleansing, and before heavier creams and/or oil serums. Enjoy!

Shelf Life & Storage

Because this gel contains water, you must include a broad-spectrum preservative to ward off microbial growth. This is non-optional. Even with a preservative, this project may eventually spoil as our kitchens are not sterile laboratories, so in the event you notice any change in colour, scent, or texture, chuck it out and make a fresh batch.


As always, be aware that making substitutions will change the final product. While these swaps won’t break the recipe, you will get a different final product than I did.

Gifting Disclosure

The frosted soft squeeze tube was gifted by YellowBee. The hyaluronic acid was gifted by Pure Nature.
