Urea

Urea in Skincare: NMF Hydrator & Texture Softener for Dry, Rough Skin

Urea is a key natural moisturizing factor that hydrates and softens rough, dry skin, and at higher levels gently exfoliates thickened areas. Learn when to choose low vs high strengths, how to pair urea with ceramides and why it’s best used after—not during—device treatments.

Efficacy

Urea is part of the skin’s natural moisturizing factor (NMF). At low levels it hydrates and softens the stratum corneum; at higher strengths it can gently break down thickened keratin, often used for rough areas like elbows and heels.

Suitable

Suitable in low strengths for dry, rough and thickened skin, considered pregnancy-safe.
High concentrations may sting on broken or very sensitive skin; use gentle low-strength formulas on the face.

Pair – other ingredients

Good with: Combines nicely with glycerin, HA, ceramides and panthenol for intensive hydrating and softening care.
Avoid / caution: Avoid heavy layering with strong acids on sensitive skin.

Pair with beauty device

Urea is best used after treatments as part of creams/lotions to soften and hydrate, rather than as a conductive gel during device use, to avoid potential stinging on sensitized skin.

Skin Type

Ideal for dry, rough and thickened skin; use low strengths on sensitive or compromised areas.

⚠️ Expert Safety Tips & Usage Guidelines

To ensure the best results and safety when using our skincare devices and products, please adhere to the following guidelines:

When using RF (Radio Frequency) or EMS (Microcurrent) devices, you MUST use a water-based gel or serum. Oil-based products will block the current, rendering the device ineffective and potentially causing heat accumulation on the skin surface.

On days you use energy-based devices (especially RF or heating modes), please pause the use of strong active ingredients such as AHAs, BHAs, or Retinol. Combining high heat with potent exfoliants may damage the skin barrier and cause irritation.

Before applying any new serum or gel to your face, always perform a patch test on your inner arm or behind the ear. Wait 24 hours to ensure no allergic reaction occurs.

Post-treatment skin (especially after Brightening or LED therapy) can be photosensitive. You must apply a broad-spectrum sunscreen (SPF 30 or higher) daily to prevent UV damage and pigmentation rebound.
