Instagram Live - Tomorrow (Monday) at 9 pm AEST

I get a lot of questions in my Instagram message inbox and email, and even as comments on unrelated posts – about whether a routine is right, or what I think of a particular product, or what I think of an ingredient, or how to use a product. I usually get more than 20 a day, and I would love …

Common Rosacea Questions with Dermatologist Dr Estee Williams

Common Rosacea Questions with Dermatologist Dr Estee Williams

Rosacea is one of the most common skin conditions. It happens when sensitive skin isn’t just sensitive – there’s redness too, and it usually rears its head between the ages of 30 and 60. The most common form of rosacea causes flushing and affects about 15% of Caucasian women.

To get a practical perspective on rosacea since I don’t have it myself (I hope and think… touch wood), I enlisted the help of Dr Estee Williams, a New York-based dermatologist who deals with many rosacea patients (you can find her on Instagram as @DrEsteeWilliams).

Common Questions About Rosacea

Q: What are the signs of rosacea?

EW: The two main signs of rosacea are facial redness and sensitivity.

Facial redness can vary from a flush-and-blush look to “broken capillaries” around the nose, and even actual pink bumps that resemble acne (even doctors sometimes have a hard time making this diagnosis).

Sensitivity is a key feature and can present as dryness, tightness, and even painful skin. Rosacea can also cause burning, stinging, and dryness of the eyes (called ocular rosacea).

Do I Need a Special Cleanser to Remove Sunscreen?

Do I Need a Special Cleanser to Remove Sunscreen?

Here’s a myth I’ve been seeing around skincare communities: that you have to use a special cleanser to remove water-resistant sunscreen. For example:

“Keep in mind that most of these sunscreen actives are also oil-soluble (only dissolves in oil, not water), which gives sunscreens their water-proof and sweat-proof properties. Therefore, in order to completely remove sunscreen, you have to use an oil, cleansing oil, emollient cleanser, or makeup remover of some kind.” (Source: Skinacea)

Have we all been leaving sunscreen on our faces before we discovered the magic of double cleansing??

Do I Need a Special Cleanser to Remove Sunscreen?

How Do Cleansers Work?

Luckily, the answer is no. A regular cleanser will remove waterproof sunscreen! The reason for this is surfactants.

Surfactants are a special class of chemical I’ve mentioned quite a few times before. They look a bit like a tadpole, with a lipophilic (oil-loving) “tail” and a hydrophilic water-loving) “head”.

(Related posts: How Do Cleansing Balms Work?, How Does Micellar Water Work?, The Science of Face Washing)

Because of this special structure, surfactants can help oil dissolve in water and vice versa. The tail binds to oil while the head binds to water. The surfactants help the oil lift off the skin, forming little oil droplets that end up dispersed in the water as an emulsion (surfactants are also known as emulsifiers for this reason). The droplets can then be rinsed away, leaving your skin clean.
