Hello, I'm Dr. Schultz
[pause]
And welcome to DermTV.
At DermTV, I get a lot of questions about
exfoliating cleansers.
They're products with a combination of exfoliants in cleansers.
So today I’ll discuss exfoliating cleansers
with chemical exfoliants first and physical exfoliants second.
Now, as much as I stress that with chemical exfoliants,
glycolic is the gold standard,
the reality is sadly that glycolic-based cleansers
just don’t make any sense as a combination cleanser
exfoliant product. You see… you can’t get any
meaningful exfoliation from glycolic mixed into a cleanser.
That’s not to say that the cleanser won’t work,
but there’s not going to be any added benefit from the glycolic.
First of all, when you use a cleanser it’s usually on your face
for around 15-30 seconds, and that just isn’t enough time
for glycolic or any chemical exfoliant
to have a meaningful effect on your skin.
But, second and even more importantly,
glycolic acid is neutralized completely by water.
So the glycolic in the cleanser is immediately neutralized
by the water when you wet your face before you cleanse
and when you’re rinsing afterwards.
Salicylic acid is the other chemical exfoliant
included in some cleansers.
While salicylic acid isn’t destroyed by water the way glycolic is,
again, there won’t be any meaningful added benefit of exfoliation
from the salicylic during the 15-30 seconds
that the cleanser is on your face.
But now, finally some good news.
Cleansers with physical exfoliants like cleansing grains
or scrubs can be effective depending on
the size and shape of the particles,
and what the particles are made of.
So, in this case you can actually get some exfoliation
during the cleansing process as you’re massaging
the granular scrub into your face.
And the results will be directly proportional to
how long you massage the cleanser into your face,
how much pressure you rub with,
and the nature of the exfoliating granules.
But just remember, I almost always prefer chemical
to physical exfoliants because their results
are more precise and predictable.
So when it comes to cleansers,
don’t spend extra money on one
with a chemical exfoliant in it
because you’ll get very little if any
additional benefit from the exfoliant part.
