Query: what occurs whenever you use a serum with silicones adopted by a moisturiser?
A. Your moisturiser turn 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 by way of all the pieces. Silicones aren’t any match for it.
C. Your moisturiser slips by way of the cracks silicones depart behind. That barrier isn’t that impenetrable in any case.
In case you’ve answered A, you’re in good firm. I’ve misplaced depend of how many individuals suppose 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 bunch of elements 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 delicate and clean to the contact.
- They fill in nice strains and wrinkles, making them look smaller (the impact is short-term).
- They create a barrier on the pores and skin that binds water in.
That final one is the rationale why silicones get numerous hate. The phrase barrier conjures photographs of sky-high partitions of strengthened concrete. What can get by way of 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 internet. This barrier is each protecting and breathable.
Research discovered that silicones kind a versatile, 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 preserve hydration in with out suffocating your pores and skin.

Can Silicones Ship Substances By means of The Pores and skin?
Now you recognize this barrier seems to be extra like a internet than a concrete wall, let’s check out what occurs whenever you use merchandise with each silicones AND lively elements.
In case you’re utilizing, let’s say, a serum with retinol and dimethicone, you need retinol to bypass dimethicone and get by way of into your pores and skin. Is that this potential or will dimethicone stand in its manner?
My fave skincare guru Paula Begoun believes that silicones do permit lively elements to penetrate your pores and skin. She says to consider 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 elements it’s blended with ‘steep’ by way of. All elements must be suspended in some base system. A few of these elements stay on the floor, some take in. Both manner the “actives” get by way of.”
Not satisfied? An article in Superior Drug Supply Opinions 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 lively elements by way of the pores and skin and into the bloodstream.
If silicones acted as limitations 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 lively elements, the actives get by way of. However, what in case you layer them on prime of one another?
Let’s say you utilize a serum with silicones after which observe up with a moisturiser. Will the actives in your moisturiser have the ability to get by way of silicones now they’ve settled onto your pores and skin?
The Magnificence 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 elements that may 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 retaining stuff OUT of the pores and skin. Therefore, no staining.”
Dermatologist Cynthia Bailey provides that the efficacy of this barrier is determined by the focus of silicones: “It is determined by 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. Research present that various kinds of silicones work together in another way with the pores and skin. Cyclomethicone, for instance, is light-weight and evaporates shortly, whereas dimethicone stays put longer. So whether or not or not your moisturizer penetrates is determined by the kind of silicone in your serum and the way a lot of it’s current.
A excessive dose of dimethicone could make it more durable for retinol to get by way of, 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 reduce reply. It is determined by what silicones are in your merchandise and in what quantity. However, if that worries you, simply apply your actives first. Drawback solved.
The Backside Line
Do silicones stop different elements 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 could certainly wrestle to get by way of. In case your skincare product is loaded with dimethicone, you might need to apply it final.
