Query: what occurs if you use a serum with silicones adopted by a moisturiser?
A. Your moisturiser develop into ineffective. It might probably’t penetrate the barrier silicones go away in your pores and skin.
B. Your moisturiser is a brilliant cookie and simply penetrates by means of every part. Silicones are not any match for it.
C. Your moisturiser slips by means of the cracks silicones go away behind. That barrier isn’t that impenetrable in any case.
When you’ve answered A, you’re in good firm. I’ve misplaced rely 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 probably not 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 elements derived from silica. Probably the most well-known are dimethicone, cyclomethicone and phenyl trimethicone. Mainly, if it ends in -cone, it’s possible 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 easy to the contact.
- They fill in advantageous 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 rationale why silicones get lots of hate. The phrase barrier conjures pictures of sky-high partitions of strengthened concrete. What can get by means of that?
That’s not what silicones make. Silicones have a explicit molecule construction that’s product of bigger molecules with wider areas between every molecule.
Consider it extra as a web. This barrier is each protecting and breathable.
Research discovered that silicones type a versatile, semi-permeable layer. In plain English, pores and skin can nonetheless perspire, however water loss is minimized. That’s the great thing about silicones: they maintain hydration in with out suffocating your pores and skin.

Can Silicones Ship Substances By means of The Pores and skin?
Now you realize this barrier seems to be extra like a web than a concrete wall, let’s check out what occurs if you use merchandise with each silicones AND lively elements.
When you’re utilizing, let’s say, a serum with retinol and dimethicone, you need retinol to bypass dimethicone and get by means of into your pores and skin. Is that this attainable or will dimethicone stand in its approach?
My fave skincare guru Paula Begoun believes that silicones do enable lively elements to penetrate your pores and skin. She says to consider them as tea luggage:
“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 means of. All elements need to be suspended in some base system. A few of these elements stay on the floor, some soak up. Both approach the “actives” get by means of.”
Not satisfied? An article in Superior Drug Supply Critiques 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 means 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 means of. 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 by means 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 all of sudden, the elements 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 coloration) the silicones have had time to arrange as a movie and they also do a greater job of holding stuff OUT of the pores and skin. Therefore, no staining.”
Dermatologist Cynthia Bailey provides that the efficacy of this barrier depends upon the focus of silicones: “It depends upon how a lot dimethicone is within the product, although. Merchandise with a considerable amount of dimethicone might nicely 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 rapidly, whereas dimethicone stays put longer. So whether or not or not your moisturizer penetrates depends upon the kind of silicone in your serum and the way a lot of it’s current.
A excessive dose of dimethicone might make it more durable for retinol to get by means of, however different silicones (like cyclomethicone) are extra risky and evaporate out of your pores and skin rapidly.
As at all times, there’s probably not a transparent lower reply. It depends upon 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 forestall different elements from penetrating pores and skin? No. Silicones type a barrier on the pores and skin that’s breathable and but prevents water loss. They don’t forestall the actives which are in the identical merchandise as them from penetrating your pores and skin. However, something you apply afterward might certainly wrestle to get by means of. In case your skincare product is loaded with dimethicone, you might wish to apply it final.
