The Complete Guide to Hyaluronic Acid: How to Use It Correctly

What Does Hyaluronic Acid Do?

Hyaluronic acid is a humectant that draws water from the environment into the upper skin layers. One gram of HA can hold up to 6 litres of water.

The Right Way to Apply

Apply to damp skin not dry skin. This is critical. Apply immediately after cleansing while your skin is still wet. On dry skin in dry conditions it draws moisture away from your skin.

The Most Common Hyaluronic Acid Mistake in Pakistan

Hyaluronic acid can actually dehydrate your skin in dry environments — the opposite of what it is meant to do. This paradox catches many Pakistani users off guard, especially in Islamabad's dry winters or inside air-conditioned offices.

HA is a humectant: it draws moisture from wherever moisture is available. In humid Karachi, it draws moisture from the air — exactly as intended. In dry indoor environments or dry seasons, when ambient humidity is low, it draws moisture from deeper layers of your skin instead, increasing water loss through the skin surface.

The fix: always seal HA with a moisturiser or oil immediately after application. Apply HA to slightly damp skin (not dry), then apply cream or lotion within 30-60 seconds to trap the moisture. This prevents the "dehydration paradox" and ensures you get the full plumping benefit HA is meant to provide.

HA Molecular Weight and Which Products to Choose in Pakistan

Modern HA serums use different molecular weights for different effects:

• High molecular weight HA (1,000-1,800 kDa) — Sits on skin surface, immediate plumping. Good for dry, dehydrated skin. Does not penetrate deeply.
• Low molecular weight HA (10-50 kDa) — Penetrates into the dermis for deeper hydration. Better for fine lines and long-term elasticity.
• Sodium hyaluronate — The salt form of HA, slightly better penetration, more stable in formulas. Most "hyaluronic acid" products actually use sodium hyaluronate.

The Ordinary Hyaluronic Acid 2% + B5 (available at BigBasket.pk, PKR 900-1,300) uses multiple HA molecular weights plus vitamin B5 (panthenol) for layered hydration. It is one of the most complete HA formulas available in Pakistan at its price point. Apply to damp skin, follow with CeraVe or any ceramide moisturiser to seal. This combination resolves dehydration and improves the performance of every other product in your routine by giving them a better-hydrated surface to work on.
