Query: what occurs once you use a serum with silicones adopted by a moisturiser?
A. Your moisturiser change into ineffective. It could’t penetrate the barrier silicones depart in your pores and skin.
B. Your moisturiser is a brilliant cookie and simply penetrates via all the pieces. Silicones aren’t any match for it.
C. Your moisturiser slips via the cracks silicones depart behind. That barrier isn’t that impenetrable in any case.
In the event you’ve answered A, you’re in good firm. I’ve misplaced depend of how many individuals assume silicones create an impenetrable barrier on the pores and skin that suffocates it and prevents anything you apply afterwards from penetrating it.
However that’s not likely what’s happening. Seems, silicones aren’t that impenetrable in any case…
What Are Silicones And Why Are They In Your Skincare Merchandise?
First issues first. Silicones are a gaggle of components derived from silica. Probably the most well-known are dimethicone, cyclomethicone and phenyl trimethicone. Mainly, if it ends in -cone, it’s seemingly a silicone.
They’re utilized in skincare merchandise for a number of causes:
- They give slip to a product, in order that it spreads simply in your pores and skin.
- They make pores and skin silky tender and clean to the contact.
- They fill in effective traces and wrinkles, making them look smaller (the impact is momentary).
- They create a barrier on the pores and skin that binds water in.
That final one is the explanation why silicones get lots of hate. The phrase barrier conjures photographs of sky-high partitions of bolstered concrete. What can get via that?
That’s not what silicones make. Silicones have a specific molecule construction that’s made from bigger molecules with wider areas between every molecule.
Consider it extra as a web. This barrier is both protective and breathable.
Studies found that silicones form a flexible, semi-permeable layer. In plain English, pores and skin can nonetheless perspire, however water loss is minimized. That’s the fantastic thing about silicones: they maintain hydration in with out suffocating your pores and skin.

Can Silicones Ship Substances Via The Pores and skin?
Now you realize this barrier appears to be like extra like a web than a concrete wall, let’s check out what occurs once you use merchandise with each silicones AND energetic components.
In the event you’re utilizing, let’s say, a serum with retinol and dimethicone, you need retinol to bypass dimethicone and get via into your pores and skin. Is that this doable or will dimethicone stand in its approach?
My fave skincare guru Paula Begoun believes that silicones do permit energetic components to penetrate your pores and skin. She says to think about them as tea baggage:
“Once you steep the tea bag in water the tea and all of its antioxidant properties are launched. Silicones stay on the floor of your pores and skin and the opposite components it’s blended with ‘steep’ via. All components should be suspended in some base system. A few of these components stay on the floor, some take in. Both approach the “actives” get via.”
Not satisfied? An article in Advanced Drug Delivery Reviews discusses how silicones are generally utilized in transdermal patches (these stick-on meds for issues like nicotine cravings and hormone remedy). These patches are designed to ship energetic components via the pores and skin and into the bloodstream.
If silicones acted as obstacles stopping penetration, these patches wouldn’t work. However they do.

Do Silicone Stop Different Substances And No matter Product You Apply Subsequent From Penetrating Your Pores and skin?
If a product has each silicones and energetic components, the actives get via. However, what when you layer them on high of one another?
Let’s say you utilize a serum with silicones after which comply with up with a moisturiser. Will the actives in your moisturiser have the ability to get via silicones now they’ve settled onto your pores and skin?
The Beauty Brains, in a response to a reader asking why her hair dye doesn’t stain her pores and skin when she applies a cream with silicones beforehand, hazard an informed guess:
“Once you apply a cream containing “goodies” together with silicones, the cream hits the face suddenly, the components that can penetrate have time to sink into the pores and skin earlier than all of the water evaporates and the silicones arrange an occlusive movie. Once you apply a silicone cream FIRST after which someday later apply one other product (like a hair colour) the silicones have had time to arrange as a movie and they also do a greater job of protecting stuff OUT of the pores and skin. Therefore, no staining.”
Dermatologist Cynthia Bailey provides that the efficacy of this barrier relies on the focus of silicones: “It relies on how a lot dimethicone is within the product, although. Merchandise with a considerable amount of dimethicone might properly block tretinoin if they’re utilized first.”
FYI, not all silicones are created equal. Studies show that different types of silicones interact differently with the skin. Cyclomethicone, for instance, is light-weight and evaporates shortly, whereas dimethicone stays put longer. So whether or not or not your moisturizer penetrates relies on the kind of silicone in your serum and the way a lot of it’s current.
A excessive dose of dimethicone might make it tougher for retinol to get via, however different silicones (like cyclomethicone) are extra risky and evaporate out of your pores and skin shortly.
As at all times, there’s not likely a transparent minimize reply. It relies on what silicones are in your merchandise and in what quantity. However, if that worries you, simply apply your actives first. Downside solved.
The Backside Line
Do silicones stop different components from penetrating pores and skin? No. Silicones kind a barrier on the pores and skin that’s breathable and but prevents water loss. They don’t stop the actives which might be in the identical merchandise as them from penetrating your pores and skin. However, something you apply afterward might certainly wrestle to get via. In case your skincare product is loaded with dimethicone, you could wish to apply it final.
