What is tocopherol in skincare?
Tocopherol is the INCI name for vitamin E in its natural, unesterified form – most often alpha-tocopherol, the variant the body uses most readily. If you see it on an ingredients list, you are looking at active vitamin E rather than a precursor.
Being fat-soluble, it embeds in the lipid layers of the skin barrier, where it neutralises free radicals and protects cell membranes from oxidation.
What skin concerns does tocopherol treat?
It defends against UV and pollution-driven oxidative stress, conditions dry and rough skin as an emollient, and helps the barrier retain water. In formulations it doubles as a preservative for other oils, slowing rancidity.
It is often included at low percentages precisely for that stabilising role. As a standalone treatment for scars or stretch marks the evidence is thin, and undiluted tocopherol oil can irritate sensitive skin.
What ingredients are best paired with tocopherol?
Pairing it with vitamin C and ferulic acid is the best-documented combination, producing greater photoprotection than any of them alone and keeping the vitamin C stable for longer.
It also sits comfortably with squalane, ceramides, niacinamide and plant oils. Acne-prone skin should look for it in a lightweight serum rather than a rich balm. Take our Skin Quiz.
What is dry skin?
Dry skin – xerosis in clinical terms – is a skin type that lacks oil rather than water. It feels tight after cleansing, looks flaky or rough, may show fine cracking, and often reads dull because the uneven surface scatters light.
It is worth separating dry skin from dehydrated skin: dryness is a lack of lipids and is usually lifelong, while dehydration is a temporary lack of water and can happen to oily skin too. Many people have both at once.
What causes dry skin?
At the root is a compromised moisture barrier. When ceramides, cholesterol, fatty acids and natural moisturising factors run low, water evaporates out of the skin faster than it can be replaced.
Age, genetics, cold weather and low humidity, long hot showers, harsh surfactants, over-exfoliation, some medications, and conditions such as eczema and psoriasis all deplete those lipids. Consistent moisturising is the single intervention with the strongest evidence behind it.
What ingredients are best for dry skin?
Rebuild in layers. Humectants such as hyaluronic acid, glycerin, urea and panthenol draw water in; emollients such as squalane, jojoba oil and shea butter smooth the surface; and occlusives seal the whole thing in.
Ceramides, cholesterol and fatty acids are the priority, because they replace exactly what a dry barrier is missing, with niacinamide helping the skin make more of its own. Apply to damp skin, and swap foaming cleansers for cream or oil-based ones. Take our Skin Quiz to find the right combination for your skin.
