GHK-Cu peptide skincare claims: What TikTok gets wrong

What did @vicky.derosa actually say?

Vicky, 59, describes a morning routine where she soaks a white washcloth in hot water, presses it to her face for a few minutes to "let your pores open up," then pats skin dry while still damp, and immediately applies a moisturizer or facial oil. She insists on white towels only, warns against rubbing, and promises you'll "glow like a goddess." The routine is simple, low-cost, and presented as the secret behind her skin at 59.

No products are named, no peptides mentioned, no injections involved. This is a basic warm compress plus occlusive moisturizer technique. That framing is important: some of what she says tracks with real dermatology, and some of it is overstated or based on a persistent myth.

Does the science back this up?

Partially, yes. The warm-compress-then-moisturize sequence has real physiological logic behind it, but the "pores open up" explanation is the part that keeps dermatologists grinding their teeth.

Here is what the research actually supports. Applying a warm, moist compress increases skin surface temperature and transiently boosts blood flow to the dermis. A study by Akimoto et al. (2016, Skin Research and Technology) found that warm facial massage increased dermal blood flow and improved short-term skin hydration measures. Separately, the practice of applying moisturizer to slightly damp skin is supported by evidence: water in the stratum corneum improves the penetration of humectants and emollients. Sethi et al. (2016, Indian Journal of Dermatology) reviewed occlusion and moisturizer efficacy and confirmed that application to moist skin improves hydration retention. So the sequence Vicky describes, warm compress followed by immediate moisturizer application, has a defensible mechanism.

The "pores open" part is the problem. Pores are not muscular structures. They do not open and close like valves. This has been repeated by dermatologists including Krant (2013, JAMA Dermatology correspondence) and confirmed in consumer-facing reviews of the evidence. Heat may temporarily soften sebaceous plugs, which can make pores appear cleaner, but no peer-reviewed study has demonstrated that pores mechanically dilate in response to steam or warm water.

What did they get wrong (or right)?

Let's be direct. The white towel advice is essentially harmless but oversold. The real concern with colored towels is dye transfer on sensitized or compromised skin, which is a legitimate issue for people with contact dermatitis or rosacea, but not a universal skin rule. For most people with intact skin, a clean colored towel is fine.

What she got right:

• Patting, not rubbing, is genuinely better for skin barrier integrity. Rubbing creates friction that can disrupt the stratum corneum, particularly in older adults whose skin is thinner and more fragile. Ghadially et al. (1995, Journal of Investigative Dermatology) documented age-related decline in barrier recovery speed.
• Applying oil or moisturizer while skin is still damp is a well-supported technique for maximizing hydration.
• A warm compress can temporarily improve skin texture and circulation. The effect is real, even if transient.

What she got wrong:

• Pores do not "open up" in response to heat. This is a myth. Warm water can loosen debris, but the mechanism is not what she describes.
• "Flawless skin" is a marketing word, not a clinical outcome. No topical routine eliminates the structural changes of intrinsic aging: collagen cross-linking, loss of subcutaneous fat, reduced elastin production.

What should you actually know?

This routine is not harmful, and for people over 50, a gentle warm compress plus immediate moisturizer application is actually a reasonable habit. The barrier function of aging skin becomes less efficient, and supporting hydration through simple occlusive techniques is consistent with what dermatology recommends.

But the "flawless skin" promise deserves skepticism. Intrinsic aging is driven by genetics, cumulative UV exposure, and cellular-level changes in collagen synthesis, none of which a warm washcloth reverses. Chung et al. (2001, Journal of Investigative Dermatology) established that photoaging and intrinsic aging have distinct but overlapping molecular pathways. Topical hydration addresses surface appearance temporarily. It does not remodel the dermis.

For people interested in skin-focused interventions with more clinical depth, GHK-Cu (a copper peptide) has peer-reviewed support for collagen stimulation and skin repair at the cellular level, per Pickart and Margolina (2018, Biomolecules). That is a different category of intervention than what Vicky describes here. The warm towel trick and clinically studied topical peptides are not comparable, but neither are they mutually exclusive.

The bottom line: this routine is low-risk, has partial scientific support, and is being sold with more certainty than the evidence allows. Apply your moisturizer to damp skin. Skip the goddess promises.
