1. Cold and Dry Climate (Winter)
This is the worst-case scenario for both, but for slightly different reasons.
-
Psoriasis: Cold weather slows down cell renewal, and lack of sun prevents natural UV rays from helping control inflammation. The dry air from heating dehydrates the plaques, making them thicker, stiffer, and more painful (they can even crack and bleed).
-
Atopic Dermatitis: Cold weather "breaks down" the lipid barrier. Atopic skin already lacks natural oils, and dry winter air evaporates what little moisture remains. This triggers intense pruritus (itching) and the appearance of eczema due to dehydration.
2. Warm and Sunny Climate (Summer)
This is where we see the biggest differences between the two conditions.
-
Psoriasis (General Improvement): Most patients show significant improvement. Ultraviolet (UV) radiation has a natural immunosuppressive effect that slows down excessive cell production. Additionally, environmental humidity helps soften scales.
-
Risk: A sunburn can trigger the "Koebner Phenomenon," causing new psoriasis to appear where the skin was burned.
-
-
Atopic Dermatitis (Risk of Worsening): Although moderate sun can help, sweat is the big enemy. Sweat contains salts and toxins that deeply irritate skin with eczema, causing immediate itching. Furthermore, excessive heat dilates blood vessels, increasing inflammation and scratching.
3. Humid Climate vs. Dry Climate

Adaptation Tips Based on Climate
If you are in a Dry/Cold climate:
-
Humidifiers: Use them at home to maintain ambient humidity above 40-50%.
-
Layers of clothing: Wear cotton directly against the skin to prevent rubbing from wool or synthetic fibers from irritating more in winter.
-
Short showers: Hot water in winter removes natural oils. Opt for lukewarm water and showers lasting less than 5 minutes.
If you are in a Warm/Humid climate:
-
Sweat control: If you have atopic skin, bathe with cool water immediately after sweating to remove salt residue.
-
Smart sun protection: Use mineral (physical) sunscreens, which tend to irritate sensitive skin less than chemical ones.
-
Technical clothing: Use breathable fabrics that do not trap sweat against the skin.
From our products, you can use:
1. For Atopic Skin (Lack of barrier and itching)
Atopic skin is extremely porous and reacts with itching and irritation. The goal is to "seal" the skin so it doesn't lose moisture.
Recommended product: Vitamin C Cream (50 ml).
What for?: To provide the oil phase (lipids) that atopic skin cannot produce on its own.
Why?: 50 ml cream textures are essential for creating an occlusive layer that protects against external allergens. Although vitamin C is an active ingredient, in cream format it is usually accompanied by emollient bases that soften the rough texture of atopic skin.
Usage recommendation: Apply immediately after bathing while the skin is still slightly damp to maximize cream absorption.
Supporting product: Cristagel Micelar (100 ml). It is the ideal cleanser for this type of skin, as it allows you to wash areas with plaques without stripping the few natural oils that remain, thanks to its gentle micellar technology.
2. For Psoriasis (Plaques and scaling)
Psoriasis presents accelerated cell renewal that forms dry, thick plaques. Here we need deep hydration and pH protection.
Recommended product: Teatonic (100 ml).
What for?: To soothe the area and prevent the pH from getting out of control, which aggravates itching in the plaques.
Why?: Teatonic is specifically formulated to protect the skin's pH (Protects your skin's pH). Maintaining a balanced acid mantle is vital in psoriasis to prevent secondary infections in areas where the skin cracks.
Supporting product: Cristagel Micelar (100 ml). It is the ideal cleanser for this type of skin, as it allows you to wash areas with plaques without stripping the few natural oils that remain, thanks to its gentle micellar technology.
Grandma's trick for flare-ups: Cold water and salt bath. Salt water will greatly soothe the flare-up as it is antiseptic and anti-inflammatory, and then apply the product your doctor has prescribed.
