Hand Care for Manual Workers — How to Protect Skin from Cracking, Dryness and Contact Dermatitis

Hands are the most heavily used part of the body — and at the same time one of the least protected. The skin on the backs of the hands is thin (comparable to the eye area), has few sebaceous glands and is constantly exposed to UV radiation as well as mechanical and chemical stress. In manual work — from catering and construction to gardening — these burdens multiply many times over.

Occupational contact dermatitis — the problem you won't see on Instagram

Occupational contact dermatitis (OCD) is the most common occupational skin disease in Europe. Date from the European Agency for Safety and Health at Work (EU-OSHA) shows that it accounts for more than 90% of all occupational skin disorders. It particularly affects:

• Catering and cleaning staff (constant contact with water and detergents).
• Hairdressers and beauticians (dyes, preservatives, water).
• Construction workers (cement — contains chromium VI, a potent allergen).
• Healthcare workers (frequent washing, latex gloves).

The mechanism is simple: repeated contact with water, detergents or irritants systematically destroys the skin's lipid barrier. A healthy barrier is made up of ceramides, cholesterol and free fatty acids arranged in layers (Elias's "bricks and mortar" model). When this structure is compromised, the skin loses water (TEWL rises), becomes dry, cracks and reacts more readily to allergens.

Barrier creams — your first line of defence

A barrier cream (pre-work cream) applied before contact with irritants forms a protective layer on the skin. It does not replace gloves, but it provides extra protection — especially when gloves cannot be worn continuously.

Active ingredients in barrier creams

• Dimethicone — silicones with a molecular weight of 200–350 kDa form a hydrophobic protective layer that repels water and detergent solutions. A study by Zitnan et al. (2009) found that creams containing 1–3% dimethicone reduced TEWL by 15–25% after 4 hours of exposure to SLS (sodium lauryl sulfate).
• Beeswax (Cera Alba) — a natural occlusive that forms a semi-permeable barrier. Less effective than dimethicone in wet conditions, but better tolerated by people who avoid silicones.
• Zinc Oxide — forms a physical barrier and has anti-inflammatory properties. Used in barrier creams designed for wet environments (catering, cleaning).

Check your barrier cream's formula in the PurScore ingredient database — make sure it contains active protection, not just marketing.

Gloves — yes, but with a cotton liner

Protective gloves (nitrile, vinyl or latex) are standard in many trades, but wearing them for hours on end creates problems of its own:

• Maceration: sweat building up inside the glove occlusively over-hydrates the skin, loosening the bonds between cells and leaving the skin prone to irritation.
• Glove-induced contact dermatitis: latex is a potent allergen (1–6% of the population); nitrile is safer, but vulcanisation accelerators (thiurams, carbamates) can cause sensitisation.

The solution: cotton glove liners. Thin, white cotton gloves worn under work gloves:

• Absorb sweat — reducing maceration.
• Reduce direct contact between the skin and the glove material.
• Should be changed every 2–3 hours or once they get damp.

Overnight repair — ceramides and occlusion

Night-time is the best moment for intensive hand repair, because the skin is no longer exposed to further mechanical and chemical stress. An effective night routine rests on two pillars:

1. Ceramides — rebuilding the barrier

Ceramides (Ceramide NP, Ceramide AP, Ceramide EOP) are lipids identical to those that naturally build the skin barrier. Creams containing 1–3% ceramides support the rebuilding of the "bricks and mortar" layer — particularly important after a full day of detergent exposure.

The best results come from combining ceramides with cholesterol and fatty acids in a physiological ratio (1:1:1 or 3:1:1 — a model developed by dermatologist Peter Elias).

2. Occlusion — locking in moisture

After applying a ceramide cream, put on cotton gloves overnight. Occlusion increases ceramide penetration by 30–50% (per in vivo studies) and prevents trans-epidermal water loss during sleep. After a week of regular use, the difference is visible to the naked eye.

10% urea — for calluses and thickened skin

Calluses on the hands are the skin's protective response to friction — you shouldn't file them away completely, because they'll grow back even thicker. Instead: controlled exfoliation using urea.

• Urea at 10% acts as a keratolytic — it loosens the bonds between corneocytes and gradually reduces the thickness of the hardened layer.
• It moisturises at the same time: urea is a natural component of the skin's NMF (Natural Moisturizing Factor) and binds water within the skin.
• Application: on calluses in the evening, under occlusion (cotton gloves). Results after 1–2 weeks of regular use.

Concentrations above 20% urea are intended for the heels and should not be used on the more delicate skin of the hands without consulting a dermatologist.

SPF for hands — the forgotten protection

The backs of the hands are exposed to cumulative UV radiation — especially for people working outdoors (construction, gardening, farming). The effects:

• Photoageing — the skin of the hands ages faster than the face, because it is rarely protected with an SPF cream.
• Pigmentation spots — the hands are one of the first places where sun-induced discolouration appears.
• Solar elastosis — loss of elasticity and thin, papery skin.

A simple solution: apply a hand cream with SPF 30+ in the morning and again after every hand wash. If you work in gloves — at least before and after work. Check whether your hand cream contains UV filters using our guide to reading the INCI list.
