The Mild Sun (30ml) is designed for sensitive and reactive skin - the formula uses gentle UV filters that minimize the risk of irritation, and the texture is lightweight enough to work without exacerbating sensitivity. The 30ml is a travel-sized or trial-sized bottle rather than a full daily supply - a typical daily facial SPF use runs about 0.5-1ml, making a 30ml bottle last roughly 1-2 months with regular use.

The "mild" designation reflects the filter selection more than the SPF level - most sensitive-skin sunscreens use mineral (zinc oxide, titanium dioxide) or carefully selected low-irritant chemical filters. This is the appropriate starting point for people who've found other sunscreens irritating or who have rosacea, eczema, or very reactive skin.

The Moisturizing Sun (30ml) adds meaningful hydration alongside UV protection - it functions as both a sunscreen and a lightweight moisturizer in a single step. This is useful for people with a simplified morning routine who want to reduce steps, or for people with dry or dehydrated skin that benefits from the moisture boost alongside SPF. At 30ml, like the Mild Sun, it's sized for travel or medium-term use rather than a large daily supply.

Korean sunscreens with moisturizing claims are generally reliable because the category (high-quality, texture-focused SPF) is competitive in Korea - brands put significant effort into formulation to compete with the established Korean SPF market.

The Tone-Up Sun Fluid (30ml) combines the Every Sun Day UV protection with the tone-correcting approach found in Dr.Jart+'s Up Line products. "Tone up" means it subtly brightens and evens the skin tone while protecting from UV. The fluid texture is lighter than cream and tends to layer better under makeup. It's the most cosmetically functional SPF in the range - suitable as both sun protection and a final skin-perfecting step before makeup or alone for a no-makeup look.

The 30ml is again the standard size for this range. The tone-up effect is typically subtle - adjusting warmth and dullness rather than providing opaque coverage - so people who want more correction would need a separate foundation or CC cream.

The Waterproof Sun Milk is designed for extended outdoor use, sweat, or water exposure. "Waterproof" in sunscreen (often labeled "water resistant" in regulated markets) means the SPF maintains efficacy for a set duration after water contact - typically 40 or 80 minutes depending on the specific formulation. This makes it the right choice for exercise, beach/pool days, or outdoor activities where other sunscreens would wash or sweat off quickly.

The milk texture is generally lighter than cream and applies evenly on the face without a heavy residue. It should still be reapplied every 2 hours (or after significant water exposure) - "waterproof" doesn't mean permanent protection. For daily desk use without significant sun or sweat exposure, the Mild or Moisturizing Sun might be more comfortable; save the Waterproof for when you need that specific protection profile.

The Sun Stick is Dr.Jart+'s compact SPF for midday reapplication. The solid stick format applies cleanly without touching the face with fingers, which makes it practical over makeup or bare skin during the day. Sun sticks are best used as supplemental SPF rather than a primary morning application - applying full-face coverage evenly with a stick is harder than with a liquid or lotion. For morning application, use one of the other Every Sun Day formats; switch to the stick for midday touch-ups.

The Sun Stick is particularly useful for people who work outdoors, travel frequently, or find themselves forgetting to reapply midday. Keeping it in a bag makes SPF reapplication a much lower barrier than carrying a bottle of lotion.

Korean sunscreens, particularly from brands like Dr.Jart+, have a strong international reputation for light, cosmetically elegant textures compared to Western SPF products. This is partly because Korea has high consumer demand for daily facial SPF use - sunscreen must be comfortable enough to wear every day for the market to accept it. The result is product development that prioritizes texture alongside protection, producing sunscreens that feel more like skincare than a chore.

All five Every Sun Day products reflect this philosophy. The 30ml sizes are also a Korean market standard - face sunscreen is applied in smaller amounts than body sunscreen and is replenished more frequently, so the smaller format is practical rather than a drawback.

Quick guide: sensitive or reactive skin → Mild Sun. Dry skin or simplified routine → Moisturizing Sun. Pre-makeup or brightening finish → Tone-Up Sun Fluid. Sports, beach, or outdoor activity → Waterproof Sun Milk. Midday reapplication or travel → Sun Stick. Each product can be used independently, or you can combine - for example, the Moisturizing Sun in the morning and the Sun Stick for midday touch-ups.

Most people apply significantly less sunscreen than the amount used in SPF testing (2mg per cm² of skin surface). Under-application means the actual SPF you receive is lower than the label value - an SPF 50 applied at half the recommended amount delivers roughly SPF 7-8 in practice. For facial SPF, the recommended amount is roughly a ¼-½ teaspoon for the face and neck. Press the product in with your hands rather than rubbing it in, which can displace it unevenly. Apply as the final skincare step, at least 15 minutes before UV exposure.

SPF degrades with UV exposure over time. For continuous outdoor exposure, reapplication every 2 hours is the standard recommendation. For people indoors most of the day with brief outdoor exposure, once-daily morning application is generally considered sufficient - though midday reapplication adds meaningful protection if you have a lunch break outdoors or work near windows. The Sun Stick and powders/spray SPFs make reapplication practical without disturbing makeup. The Waterproof Sun Milk should be reapplied after significant sweat or water exposure even within 2 hours.
