During the heating season, indoor humidity drops to 20–30%, which triggers transepidermal water loss (TEWL). For skin affected by eczema or dermatitis, this is a critical factor: the damaged stratum corneum is unable to retain moisture, leading to flare-ups. Pine nut oil enriched with sea buckthorn is a therapeutic combination designed to restore the lipid matrix.

How pine nut oil enriched with sea buckthorn supports the skin's barrier function during the heating season when dealing with eczema and dermatitis

During the cold season, indoor air becomes dry, causing the skin to lose moisture. This is particularly harmful for people with eczema and dermatitis. Pine nut oil enriched with sea buckthorn helps restore the skin’s protective barrier, reducing inflammation and promoting the healing of microcracks. This combination also improves ceramide synthesis and protects the skin from harmful environmental influences. Regular use of the product helps maintain moisture and reduce the risk of flare-ups during the heating season

Repair mechanism: lipids and regeneration

Pine nut oil is rich in pinolenic acid – a rare polyunsaturated fatty acid with pronounced anti-inflammatory properties. Unlike standard oils, it modulates the immune response in the epidermis by reducing the activity of cytokines that trigger itching in dermatitis [1].

Sea buckthorn, in turn, is a source of palmitoleic acid (omega-7). This component is a structural element of the skin and promotes accelerated epithelialization of microcracks caused by dryness. Topical application of pine nut oil enriched with sea buckthorn helps stabilize the skin’s barrier function by improving ceramide synthesis [2].

Why does this work for dermatitis?

In eczema, the integrity of the “cement” layer between corneocytes is compromised. Pine nut oil provides deep nourishment without forming a comedogenic film, which is important for sensitive skin. Sea buckthorn acts as an antioxidant shield, neutralizing free radicals that form in the skin when exposed to dry air and temperature fluctuations. Together, they create an occlusive effect that physically prevents moisture evaporation, mimicking natural sebum.

Your solution for a comfortable winter

If you’re tired of constantly feeling tightness and irritation, incorporating pine nut oil enriched with sea buckthorn into your daily skincare routine isn’t just about moisturizing – it’s about restoring your skin’s structure. Applying it regularly to damp skin after a shower helps “seal in” moisture, preventing flare-ups of dermatitis during the heating season.
