"My issue is sebaceous filaments. I rarely get spots but in the last 18 months or so I noticed these tiny, hard grey bumps filled with a drop-shaped hard bead. In the last month they have increased. I get them on my chin and between my brows. I haven't tried any products on them, but I'm obsessed with squeezing them out! How can I stop them or slow down their appearance?"

"Sebaceous filaments are often under-diagnosed and mistaken for blackheads or whiteheads. While their origin is the same as those pesky pimples – the pilosebaceous unit (pores) – their characteristics are very different.
A sebaceous filament is a tiny collection of sebum (oil) and old dead skin cells, which accumulate around a hair follicle. They usually take the form of a small, white or yellowish, hair-like strand. Sebaceous filaments are usually only found around the thin skin of the nose, unlike blackheads and whiteheads, which can form anywhere on the face.
If you analysed the histology of a sebaceous filament, you would see that they are composed of a skeleton structure of up to 30 horn-like cell layers. These are mixed with a blend of skin bacteria, sebaceous oils, corneocytes and a single hair. The reason I like to break down the structure of these filaments is that it enables us to select the best treatments to break the structures down.
To target the filaments you can add some fantastic skin ingredients into your daily skincare routine. Adding in a combination alpha and beta hydroxy acid cleanser will help, thanks to its double-action cleansing mechanism. The lactic and glycolic acid will help to exfoliate and remove dead skin cells, while the salicylic acid will seep into your pores, reduce bacteria, oil and pilosebaceous inflammation. Start off by using this at nighttime, which in my opinion should always be the more intensive cleanse in your regimen.
Dehydration can trigger an internal ‘skin repair’ mechanism, whereby the sebaceous glands try to rehydrate the skin, by switching on faster sebum production. This will undoubtedly increase the rate of pore clogging. The key to prevent this is to ensure that you have adequate skin hydrators in your skincare but to also take care to avoid those pore-clogging facial oils and comedogenic moisturisers. High molecular-weight hyaluronic acid in your morning and night serums will be your skin saviour. This natural skin hydrator hydrates and nourishes the epidermal and dermal layers, without pore-clogging.
Adding in a retinoid (vitamin A) serum or night cream will be a great asset for your skin. This multitasking skin nutrient will reduce sebum, bacteria, inflammation and improve epidermal turnover. There's no need to blitz your skin with high doses of retinoids to address this skin concern. 0.5-1% of a second or third generation retinoid works wonders and I find products with additional hyaluronic acid in the formula help to counteract any dryness or irritation that one may see typically after using these types of products.
To take things up a gear you can also seek advice from a dermatologist. There are numerous treatments that can assist, such as salicylic acid peels and professional extractions. I also like to add in Q-switch high-powered clearlift laser treatments too, which can really enhance the efficacy of your topical treatments."
