Preparation H can temporarily reduce the appearance of puffiness around the eyes, but it does not treat or reduce wrinkles. The effect people notice is a short-lived tightening of the skin caused by one of its active ingredients, which constricts blood vessels. Once that wears off, usually within a few hours, the skin returns to its previous state. There is very little evidence that hemorrhoid creams help with wrinkles, and regular use on your face can cause real harm.
Why People Think It Works
This beauty hack has circulated for decades, often credited to makeup artists and pageant contestants looking for a quick fix before going on camera. The idea is simple: if Preparation H can shrink swollen hemorrhoid tissue, it should be able to tighten puffy skin under the eyes or smooth out fine lines on the face.
There’s a kernel of truth here, but it’s a small one. The standard Preparation H cream contains phenylephrine at 0.25%, a vasoconstrictor that narrows blood vessels. When applied to skin, phenylephrine reduces local blood flow, which can temporarily deflate puffiness. Some dermatologists acknowledge this ingredient may help with puffy, tired-looking eyes in the short term. But puffiness and wrinkles are fundamentally different problems. Puffiness involves fluid retention; wrinkles involve structural changes in collagen and elastin deep in the skin. Phenylephrine does nothing to rebuild those proteins.
What’s Actually in Preparation H
The maximum strength cream version contains four active ingredients: glycerin (14.4%) and white petrolatum (15%) as skin protectants, phenylephrine (0.25%) as a vasoconstrictor, and pramoxine (1%) as a local anesthetic. These ingredients are designed to soothe irritated rectal tissue, reduce swelling, and relieve pain. None of them stimulate collagen production, increase skin cell turnover, or address the underlying causes of facial aging.
Older formulations of Preparation H contained a compound called live yeast cell derivative, or LYCD, which had some evidence of promoting wound healing in burns and damaged tissue. That ingredient was the original basis for the “Preparation H for your face” claim. LYCD is no longer in the product sold in the United States, so even that tenuous connection to skin repair no longer applies.
The Hydrocortisone Problem
Some versions of Preparation H contain hydrocortisone, a steroid that reduces inflammation. This is where the real danger lies for anyone using it on their face. Facial skin is significantly thinner than skin elsewhere on the body, which means it absorbs topical steroids more readily and is far more vulnerable to their side effects.
Even short-term use of topical steroids can alter the structure of the outer skin layer and compromise the skin barrier. With repeated application, the consequences get worse: thinning skin, loss of elasticity, increased fragility, visible blood vessels (telangiectasia), easy bruising, and a transparent, papery texture. Steroids directly inhibit the fibroblasts that produce collagen and suppress the synthesis of collagen itself. In other words, the very protein you need more of to reduce wrinkles is the one hydrocortisone breaks down.
Hydrocortisone applied to the face can also trigger or worsen rosacea, acne, and other inflammatory skin conditions. In older adults, topical steroids can aggravate a condition called Bateman’s purpura, causing deep bruising under fragile skin. The Mayo Clinic specifically warns against prolonged use of hydrocortisone on the face for these reasons.
Why the Temporary Effect Isn’t Worth It
Even if you stick to the phenylephrine version and avoid hydrocortisone entirely, the tradeoff is poor. The tightening effect lasts a few hours at most. Repeated vasoconstriction can irritate facial skin over time, and the protectant ingredients like petrolatum, while excellent moisture barriers for damaged rectal tissue, can clog pores and contribute to breakouts when applied to the face.
The bigger issue is opportunity cost. If you’re applying Preparation H instead of a product with proven anti-aging ingredients, you’re losing ground. Retinoids increase collagen production and speed cell turnover. Vitamin C serums protect against oxidative damage and brighten skin tone. Peptide-based moisturizers signal skin cells to produce more structural proteins. Sunscreen prevents the UV damage responsible for the majority of visible aging. Each of these has a body of clinical evidence behind it. Preparation H has none for wrinkle reduction.
What the Tightening Effect Is Good For
If you have a special event and noticeable under-eye puffiness, a small amount of the phenylephrine-based (not hydrocortisone) version applied carefully under the eyes may temporarily reduce swelling. This is a cosmetic trick, not a treatment. Use it sparingly, keep it away from your actual eyes, and don’t make it a habit. For everyday puffiness, a cold compress, adequate sleep, and reducing salt intake will accomplish the same thing without any risk to your skin.
For actual wrinkle reduction, the proven path is consistent use of sunscreen, a retinoid appropriate for your skin type, and moisturizers that support the skin barrier. These work slowly, over weeks to months, but they address the structural causes of wrinkles rather than masking them for an afternoon.
