What is witch hazel in skincare?
Witch hazel is an extract of the bark and leaves of Hamamelis virginiana, a North American shrub. Its activity comes from tannins – principally hamamelitannin – which bind proteins and make tissue contract, the classic astringent effect.
The critical variable is formulation. Traditional distillates are preserved with 14 to 15% alcohol, which is what gives many witch hazel toners their reputation for drying skin out. Pharmacological reviews of the plant credit it with antioxidant and anti-inflammatory activity independent of that alcohol.
What skin concerns does witch hazel treat?
It temporarily tightens the look of pores, reduces surface oil and calms minor inflammation, which is why it appears in products for oily and acne-prone skin. Extracts show documented anti-inflammatory and anti-acne effects.
It also soothes insect bites, minor grazes and razor burn. Used daily in an alcohol-heavy form, however, it strips the barrier and can push skin into producing more oil, not less.
What ingredients are best paired with witch hazel?
Choose an alcohol-free formulation and follow it with hydration – hyaluronic acid, glycerin, niacinamide – plus ceramides to keep the barrier intact.
For the concerns it is usually bought for, salicylic acid and niacinamide do more with less collateral dryness. Treat witch hazel as an occasional soothing step rather than a daily toner. Take our Skin Quiz.
What is oily skin?
Oily skin is a skin type in which the sebaceous glands produce more sebum than the skin needs. It shows up as shine through the T-zone within hours of cleansing, visibly enlarged pores, makeup that slides or separates, and a tendency towards blackheads and congestion.
Sebum itself is not the enemy – it carries vitamin E to the surface, keeps the barrier supple and helps oily skin hold its structure, which is why it often shows fine lines later than dry skin does.
What causes oily skin?
Genetics and androgen activity are the primary drivers of how much sebum your glands produce. Heat and humidity increase output measurably, and hormonal fluctuations across the monthly cycle, pregnancy or puberty shift it again.
Stress, a diet heavy in refined carbohydrates, and – counter-intuitively – over-cleansing with stripping foams or alcohol-based toners all push oil production up, because skin compensates for a damaged barrier by making more.
What ingredients are best for oily skin?
Look for salicylic acid (a BHA that is oil-soluble, so it clears inside the pore), niacinamide and zinc to regulate sebum, clay such as bentonite or kaolin for weekly absorption, and retinoids or azelaic acid to normalise how pores shed.
Do not skip hydration: lightweight humectants like hyaluronic acid and glycerin, plus non-comedogenic squalane or jojoba oil, keep the barrier intact so the skin stops over-compensating. Skip heavy occlusive balms and high-alcohol toners. Take our Skin Quiz to get the balance right for your skin.
