Sunblock vs Sunscreen vs Sun Cream: What the Names and Textures Really Mean
Sunblock, sunscreen, sun cream, sun milk, sun serum: the names sound different, but the label numbers do the real work. A plain guide to the terms and the textures behind them.
Walk down a Singapore pharmacy aisle and you will see sunblock, sunscreen, sun cream, sun milk, UV essence and sun serum, sometimes all from the same brand. It is natural to wonder whether "sunblock" is stronger, or whether a "sun cream" is only for the beach.
The short answer: the name on the front tells you very little about protection. The SPF and PA (or broad-spectrum) rating tells you the protection level, and the format word (milk, gel, cream, stick) tells you the texture. This guide untangles the names and explains how each texture behaves, so you can pick the one that fits your day.
Sunblock vs sunscreen: is there a real difference?
Historically, "sunblock" was used for products that physically blocked light, usually thick zinc oxide pastes, while "sunscreen" meant products that absorbed UV. Today the line has blurred completely. Modern mineral sunscreens absorb UV as well as scattering it, and many "sunblock" products use the same filters as any sunscreen.
Some regulators have discouraged the word "sunblock" because it suggests total protection, which no product offers. In Singapore and across Asia you will still see it on packs and in product listings, for example Avène Triasorb SPF50+
AveneAvene Sunblock - Triabsorb SPF50+ 50mlThe fragrance-free SPF 50+ Cream offers ultra-broad spectrum daily sun protection that protects against UV rays and beyond in blue light, a skin-ageing accelerator, up to 450nm. . It is ideal for dry sensitive facial skin. Its velvety, melting texture moisturises the face for up to 8 hours* leaving the skin nourished and soft to the touch. Fragrance-Free Cream SPF 50+ leaves an imperceptible, non-shiny finish on the skin and is an excellent base for everyday make-up. The formula is also water resistant.

So: sunblock and sunscreen mean the same thing in practice. Compare the numbers, not the noun.
Sun cream, sun lotion, sun milk: all texture words
These words describe how the product feels and spreads, not how much it protects. A sun cream with SPF 50 and a sun milk with SPF 50 offer the same labelled protection when applied in the same amount.
For a fuller explanation of the numbers themselves, see our guide to SPF, PA++++ and broad spectrum. Here is the quick version:
SPF measures protection mainly against UVB, which drives sunburn.
PA+ to PA++++ rates UVA protection, which is linked to tanning, pigmentation and skin ageing.
Broad spectrum means the product covers both UVA and UVB to a set standard.
UV filters are the active ingredients doing the work; "mineral" and "chemical" describe the type.
The main textures, and who they suit
Sun milk
A thin, often shake-before-use liquid. Milks are common in Japanese sunscreens and are often water-resistant, making them a favourite for outdoor days. Shiseido Anessa Perfect UV Sunscreen Milk SPF50+ PA++++

Good for: body, back, hair parting, quick reapplication. Trade-off: much of the spray drifts away, so most people apply too little. Spray until skin looks wet, then rub in. Our guide on spray sunscreen covers the details.
UV protection "for face" vs "for body"
Face sunscreens tend to be lighter, less fragranced and designed to sit under makeup. Body sunscreens often come in larger bottles, may be fragranced, and are usually more water-resistant. Many products are labelled for both, which is handy for travel.
Using a body sunscreen on your face is not dangerous, but some people find body formulas heavier or more likely to sting the eyes. Using a face sunscreen on your body is fine too, just expensive.
Three mistakes the names can cause
Assuming "sunblock" means you can skip reapplication. Every sunscreen needs reapplying after sweat, swimming or towelling, and roughly every two hours outdoors.
Thinking a "sun cream" is only for holidays. Any format can be a daily sunscreen; choose the texture you like.
Choosing the format but ignoring the amount. About two finger-lengths for face and neck matters more than any label wording.
Bottom line
Sunblock, sunscreen and sun cream all do the same job. The SPF and PA rating tells you how much protection you get; the format word tells you how it feels. Choose a milk or spray for outdoor days, a gel or fluid for humid office days, a cream for drier skin, and a stick for top-ups. Then apply enough, every day.
