Dry Skin & Skin Hydration Treatments in Singapore

Dryness (xerosis) is a measurable shift in skin barrier biology. How well the skin barrier or stratum corneum retains water controls transepidermal water loss (TEWL). When this system is disrupted, skin can feel tight, look dull or flaky, sting with products, and become reactive. Effective treatment starts by restoring barrier function and supporting hydration deeper in the dermis.

What is dry skin?


Dry skin (xerosis cutis) is a state where the skin has insufficient water and/or surface lipids to maintain normal softness and barrier function. Clinically it can present as roughness, scaling, tightness, and sometimes itch or sensitivity. 

Dry skin vs dehydrated skin 

  • Dry skin: Often linked to reduced lipids (e.g. ceramides) and impaired  moisture barrier function.
  • Dehydrated skin: Is due to transepidermal water loss from barrier disruption (e.g., over-cleansing, actives, air-conditioning), even in oily or acne-prone skin.


Both benefit from barrier repair, but treatment emphasis differs.

Why does dry skin occur?


Dry skin typically reflects a combination of:

  • Skin barrier disruption 
  • Reduced hydrolipids 
  • Genetic and inflammatory drivers (e.g., filaggrin/NMF-related barrier vulnerability in eczema-prone skin) 
  • Environment and habits that strip lipids and worsen TEWL


Where can signs be seen on the face and/or neck?


Dryness can show up anywhere, but commonly:

  • Cheeks and around the mouth 
  • Under-eyes 
  • Neck

Why does dry skin form? 


Healthy stratum corneum hydration depends on three components:

  1. Humectants to retain water: NMF components like amino acids, urea, PCA help hold water in the stratum corneum 
  2. Lipids to seal water loss: ceramides/cholesterol/fatty acids organise into lamellae that reduce TEWL and keep irritants out 

When any of these drop (e.g. over-cleansing, UV exposure, inflammation, age, or genetics) water escapes faster than it’s retained.

FAQs

How can this dry skin be treated?

At The Skin Longevity Clinic, dry skin is viewed from the lens of skin function; with an emphasis on improving barrier function and hydration and reducing inflammation.  

Foundational skin care 

  • Gentle cleansers 
  • Barrier control moisturisers with evidence-based ingredients (humectants, emollients and lipids) are the core of long-term control. 
  • Daily sunscreen to reduce UV induced barrier stress and dryness and texture changes


Skin hydration treatments

When barrier is fragile, or when you want a measurable improvement in skin smoothness and hydration quality:

 

Injectable hyaluronic acid moisturisers:

These treatments place stabilised hyaluronic acid into the dermis in microdroplets to improve skin hydration, smoothness, and fine texture—without the goal of adding volume.

What the evidence shows:

  • A randomized multicenter study found intradermal HA (VYC-12L) improved cheek smoothness, fine lines, and hydration with good tolerability. 
  • A prospective study reported hydration improvements lasting months after VYC-12 (commonly associated with “skin quality” HA injectables). 
  • A split-face study of nonanimal stabilized HA showed improvements in hydration and elasticity. 
  • A 2023 systematic review of injectable HA studies concluded HA formulations significantly improved multiple skin quality domains including hydration, elasticity, and texture. 

What is the procedure like?

A typical skin hydration injection for dermal hydration procedure at The Skin Longevity Clinic includes:

  1. Assessment & diagnosis
    We clarify whether you are dealing with xerosis, dehydration, eczema-prone barrier vulnerability, acne-reactive dehydration, or photo-stressed skin.
  2. Skin preparation
    Cleansing, photography (for objective tracking), and topical numbing.
  3. Microdroplet intradermal injections
    HA is placed superficially in the dermis in a mapped pattern (commonly cheeks; may extend to other areas depending on indication).
  4. Aftercare
    Expect small bumps, mild redness or swelling that typically settles over days. 


Results: hydration and skin improvements can be noticed within days to weeks, with durability varying by product, skin biology, and lifestyle; published studies report benefits lasting months.

Why choose Dr Rachel Ho and The Skin Longevity Clinic for dry skin treatment in Singapore?

Because dry skin is often treated too superficially—when it’s actually a barrier science problem.

At The Skin Longevity Clinic, the approach is:

  • Diagnosis-first: dry vs dehydrated vs eczema-prone vs treatment-induced barrier injury
  • Evidence-based planning: moisturisation strategy grounded in dermatology guidance 
  • Skin longevity focus: protect barrier, reduce inflammatory triggers, improve tolerance to actives, and preserve dermal quality over time
  • Deep dermal hydration treatments

Doctor Rachel’s Takeaway

Dry and dehydrated skin are a reflection of disrupted skin barrier function, resulting in increased transepidermal water loss. Dryness and dehydration can aggravate inflammation in the skin to worsen symptoms and signs of ageing. Besides supportive, barrier first skincare, skin hydration treatments with injectable hyaluronic acid moisturisers can offer longer lasting deep dermal hydration.
