Witch hazel has been in medicine cabinets for well over a century. It was a staple in post-shave products, toners, and first aid preparations long before “skincare routine” was a concept. The question isn’t whether it does something, it clearly does, but whether what it does is actually good for your skin.
The answer depends on the form of witch hazel, how it’s used, and what your skin actually needs.
What witch hazel is and what it contains
Witch hazel comes from the bark and leaves of Hamamelis virginiana, a North American flowering shrub. The plant has been used in traditional medicine by indigenous communities for centuries, primarily for its astringent and anti-inflammatory properties.
The key active compounds in witch hazel are tannins (particularly galloylated proanthocyanidins), polyphenols, and flavonoids. Tannins are responsible for the astringent effect: they temporarily tighten proteins in the skin surface, creating the sensation of tightness and pore minimising that people associate with witch hazel toners.
Most commercial witch hazel products are steam-distilled hydrosols. The distillation process removes most of the tannins, leaving primarily the volatile compounds. This is an important distinction, because most of the research on witch hazel’s anti-inflammatory and antioxidant properties is based on extracts containing significant tannin concentrations, not the distilled hydrosol found in most skincare products.
Many commercial witch hazel products also contain alcohol, often listed as SD alcohol, at concentrations between 14-15%. This is added for preservation and to enhance the astringent effect.
The case for witch hazel
Some research supports witch hazel’s benefits in specific applications. A study published in the European Journal of Pediatrics found a witch hazel preparation as effective as a cortisone cream for treating eczema in children when used in a specific formulation. Research has also shown anti-inflammatory activity from witch hazel polyphenols in laboratory and some clinical settings.
For acne-prone skin, the traditional rationale for witch hazel as a toner makes some sense. The tannins have mild antibacterial activity, and the astringent effect can reduce excess oiliness temporarily. Some people with oily, acne-prone skin genuinely find that a cotton pad soaked in witch hazel after cleansing keeps oil production in check between washes.
For mild external haemorrhoids, sunburn, and minor skin irritation, witch hazel preparations have reasonable evidence behind them. The Hamamelis water found in some pharmaceutical products differs from what’s in most skincare toners, though.
The case against witch hazel in daily skincare
The more critical view of witch hazel focuses on two things: the alcohol content in most products and the paradox of using an astringent for most skin types.
If a witch hazel product contains alcohol, the astringent and temporary tightening sensation comes largely from the alcohol, not from the plant compounds. Alcohol at 14% strips the skin’s natural oils, disrupts the lipid layer of the skin barrier, and triggers a rebound effect where skin compensates for dryness by producing more oil. This is not a good cycle for oily or combination skin, despite those being exactly the skin types most often recommended witch hazel.
Even without alcohol, the tannin-rich forms of witch hazel can be drying and irritating with daily use. Tannins are astringent by nature; they’re also found in red wine and strong tea, and for the same reason that drinking a lot of tannin-rich beverages can be irritating, applying them daily to the face is not inherently gentle.
Alcohol-free witch hazel hydrosols (which have had the alcohol removed) are gentler but also have less of the active compounds that drive the benefits. They may provide mild toning without the irritation of the alcohol-containing versions.
Who might benefit from witch hazel and who probably shouldn’t use it
Oily skin in a hot, humid climate may genuinely benefit from witch hazel as a once-daily treatment to manage excess sebum. Using an alcohol-free version, or alternating with a hydrating toner on the days between, reduces the drying effect.
Acne-prone skin might get short-term benefit from the astringent and mild antimicrobial effects, but dedicated acne treatments with salicylic acid, benzoyl peroxide, or niacinamide are better supported by evidence for actual acne management.
Dry skin, sensitive skin, compromised skin barrier, and skin with rosacea should generally avoid witch hazel. The astringent effect is the opposite of what these skin types need, and the potential for irritation is higher.
After sun exposure, diluted alcohol-free witch hazel hydrosol can help with minor redness and inflammation. This is a reasonable use case.
Where witch hazel fits in modern skincare
Witch hazel is neither the miraculous pore-minimiser and cure-all it was once marketed as, nor is it so problematic that no one should use it. It’s an ingredient with some genuine properties that can be useful in specific circumstances for specific skin types.
The widespread use of witch hazel as a daily toner for all skin types is not well supported by evidence. Using it occasionally for specific situations, such as post-shave irritation, minor sunburn, or oil control on a particularly hot day, is a more rational approach than treating it as a daily skincare staple.
If you love your witch hazel toner and your skin is doing well with it, there’s no urgent need to stop. But if you’ve been using it because you heard it’s good for your pores and you’re also dealing with dryness or reactivity, it might be worth a trial without it to see if things improve.
