Cannabidiol Reduces Skin Redness Exceptionally Quickly After a Sauna.

Written by Noora Shingler, Co-founder of Blank& · Updated November 2026

In short: Redness during sauna is caused by the dilation of superficial blood vessels in the face as the body tries to reduce its temperature. In sensitive and couperose-prone skin the redness can be intense and long-lasting. CBD reduces sauna-induced redness by binding to the skin's TRPV1 receptors, which regulate the body's response to heat. A post-sauna routine of Veya face mist followed by a CBD facial oil moisturizes the skin and soothes redness.

For many Finns, sauna is a weekly routine, and it’s no wonder so many enjoy it — there are plenty of reasons for that post-sauna sense of wellbeing. Sauna bathing can lower blood pressure, promote relaxation, and ease muscle soreness [3]. It’s also beneficial for the skin: it boosts surface circulation and opens pores, allowing skincare products applied afterward to absorb more effectively.

Red cheeks after sitting in the steam room are common, but for those with sensitive skin, the redness can be intense and long-lasting. Redness during sauna is normal and caused by the dilation of superficial blood vessels in the face and increased circulation as the body tries to reduce its temperature. However, for example, in couperose-prone skin the walls of these superficial vessels are weakened and don’t return to their normal state as quickly after being dilated by heat. In addition to the cosmetic aspect of pronounced redness, sensitive skin may also feel hot and tight after sauna.

CBD, or cannabidiol, is a skin-soothing, moisturizing, and redness-reducing ingredient. CBD works together with proteins located on the skin’s surface to effectively and quickly lessen sauna-induced redness while also soothing the sensation of heat and nourishing the skin deeply. Thanks to its anti-inflammatory properties, CBD also helps calm redness caused by inflammation in acne- or rosacea-prone skin [4].

A fascinating mechanism lies behind CBD’s redness-reducing effect after sauna

A receptor called TRPV1 plays an important role in the body’s temperature regulation. TRPV1 is a protein found in sensory nerve cells, including those present in the skin, and it reacts to heat [2]. When activated, it initiates a thermoregulation process that keeps the body’s temperature safe and prevents overheating. This leads to increased blood circulation, skin flushing, and sweating.

When absorbed into the skin, cannabidiol can bind to TRPV1 receptors and activate them briefly. This momentary activation causes the receptor to become “numbed” or desensitized, meaning it no longer reacts as strongly to heat stimuli such as sauna [1]. This weakened response results in a milder thermoregulatory reaction and therefore less facial redness.

Glow and hydration after sauna with Blank& products

Blank& products make post-sauna skincare effortless and effective. After the sauna, the skin is especially receptive to products, so it’s best to treat it with hydrating and soothing ingredients. A suitable post-sauna routine starts with the Veya facial mist, whose humectants moisturize the skin and give it a beautiful glow. On top of Veya, you can apply the Evie or Amio facial oil to lock in moisture and deeply nourish the skin. The CBD extract in all products soothes the skin and reduces redness, while the aromatherapeutic effects of essential oils enhance the sauna’s relaxing benefits.

Frequently asked questions

Why does the face turn red in the sauna?

Redness during sauna is normal. It is caused by the dilation of superficial blood vessels in the face and increased circulation as the body tries to reduce its temperature.

Why does redness last longer on sensitive skin?

In couperose-prone skin, the walls of the superficial blood vessels are weakened and don’t return to their normal state as quickly after being dilated by heat. Sensitive skin may also feel hot and tight after sauna.

How does CBD reduce redness after sauna?

CBD binds to TRPV1 receptors in the skin, which react to heat. The brief activation desensitizes the receptor, so it no longer reacts as strongly to heat such as sauna. This results in a milder reaction and less facial redness.
