Skin flooding

Overview

“Skin flooding” refers to rapid layering of multiple hydrating products, or repeated layers of the same product, onto damp skin to achieve a “glass skin” appearance. (1) “Skin Slugging” refers to the application of thick, occlusive balms such as petroleum jelly as the final step in skin care routine in an attempt to seal in moisture and prevent water loss.

Although promoted online as a method to maximize water retention within the skin barrier, the practice remains largely social media-driven, with limited clinical evidence evaluating its efficacy or safety.

Per a manual review of TikTok videos, commonly layered products include:

• Hyaluronic acid serums

• Essences

• Toners

• Mists

• Occlusives

• Barrier creams

Potential dermatologic complications

Acne

Heavy layering, particularly with occlusive or comedogenic products, may worsen acne or comedogenesis in acne-prone patients. (2)

Irritant reactions

Patients may inadvertently combine multiple fragranced or sensitizing products. (3)

Barrier disruption

Excessive occlusion can reduce stratum corneum barrier efficiency. (4)

Important history questions

• How many skincare products do you layer daily?

• Are products fragranced or comedogenic?

• Are you layering multiple essences, milky toners, hydrating mists, HA serums, oils, or occlusive products such as petrolatum or Aquaphor?

• Did acne or irritation worsen after expanding your skincare routine?

Counseling considerations

Dermatologists can counsel patients regarding:

• Simplifying overly complex regimens.

• Recognizing that more products do not necessarily improve outcomes.

• Reducing fragranced or highly sensitizing products in sensitive skin.
