Blackheads are a common skin concern that can affect people of all ages and skin types. These small, dark spots often appear on the nose, chin or forehead, but can appear anywhere on the body. While they may seem persistent, with the right understanding, products and routine you can help target some of the causes of blackheads.
With this in mind, we’re taking a deep dive into what blackheads are – why they might occur.

What are blackheads?
Blackheads are small, dark spots that appear on the skin when pores become clogged with a combination of sebum (oil), dead skin cells, and debris. Unlike whiteheads, which remain closed, blackheads are open to the air. This exposure causes the trapped material to oxidise, giving the blemish its characteristic dark appearance.
Blackheads commonly appear on the face, particularly around the nose and chin, but can also develop on other areas such as the back, chest, or shoulders.
What causes blackheads?
A variety of factors can contribute to blackhead formation, including:
1. Excess oil production
Overactive sebaceous (oil) glands can lead to an overproduction of sebum, in turn clogging pores. Hormonal changes – particularly during puberty, pregnancy or the menstrual cycle – can also lead to an increase in oil production.
2. Improper cleansing
It’s no secret that effective skincare starts with a regular cleansing routine. Failing to remove make-up and excess oil may cause pore blockages, which can worsen blackheads or cause new ones to form.
3. Dead skin build-up
Much like cleansing, exfoliating is an important step in your skincare regime. Your skin undergoes a natural turnover process, shedding the upper layer (epidermis) and revealing renewed cells underneath. Dead skin cells can accumulate on the surface of your skin, contributing to pore blockage and blackhead formation.
4. Comedogenic skincare
Heavy or oily cosmetics and products may clog pores, making blackheads more likely.
5. External factors
Pollution, sweat, and even seasonal changes can increase the likelihood of developing blackheads. These environmental shifts, along with impurities accumulating on the skin surface, can cause imbalances and blockages.
Your skin is unique, and understanding its specific needs is key to help reduce the appearance of blackheads. Learn more about what to look out for – and how to create a tailored skincare routine – with our guide to identifying your skin type.
How to help reduce the appearance of blackheads
A targeted skincare routine can help to reduce the appearance of blackheads.
Cleanse & exfoliate
Most cleansers remove impurities, make-up, and excess.
Try: For a truly thorough cleanse, reach for the No7 Hot Cloth Cleanser. Infused with our Tri-Vit Complex and red ginseng, this cleanser is formulated to help protect skin's natural, healthy, this luxurious formula works to gently exfoliate as it cleanses, leaving your complexion feeling soft, soothed, and smooth.
Try: The No7 Total Renewal Micro-Dermabrasion Facial Exfoliator comes packed with aluminium-oxide micro-crystals, sweeping away dead cells and impurities. Or, for a chemical exfoliant (and extra radiance boost), opt for the No7 Radiance+ Daily Energising Exfoliating Cleanser.
Targeted treatments
There are several ways to tailor skincare to help target some of the causes of blackheads, including:
Retinol: renowned for its brightening and smoothing properties, this powerful ingredient can help transform skin’s appearance. Our unique formulations of pure retinol and MATRIXYL 3000 Plus™ helps support surface skin cell turnover, helping prevent dead skin cells from clogging pores. While effective, retinol should be introduced gradually to avoid irritation.
Try: If you’re looking to include retinol in your skincare regimen, our Essential Night Time Retinol Bundle is a good place to start. This complete set contains everything you need, from our dermatologically tested night cream to our clinically proven Pure Retinol 0.3% Complex Night Concentrate (which has been formulated to be gentler on the skin)
Salicylic acid: also known as a BHA (beta hydroxy acid), this chemical exfoliant is similar to AHAs (alpha hydroxy acids), but with a key structural difference. While AHAs are water-soluble and act on the surface of the skin, BHAs can gently exfoliate to clear pores, remove surface dead skin cells and improve the appearance of blackheads and oiliness.
Try:No7 Derm Solutions™ Clearing Treatment is blended with 2% salicylic acid, This product is designed to deliver calmer and clearer-looking skin.
Professional help
For stubborn blackheads, professional treatments may be worth exploring. Options include:
Chemical peels: these use acids to exfoliate and reveal clearer skin
Microdermabrasion: a non-invasive procedure that removes the top layer of skin to open clogged pores
Extraction: performed by a dermatologist or aesthetician to safely remove blackheads
While effective, these treatments should complement, not replace, a consistent at-home skincare routine.
