Dr.g Sun
Dr.G's sun protection line spans stick and fluid SPF formats with three distinct finish philosophies: pore-blurring for oily skin, tone-up brightening for dull skin, and clear waterproof for active or high-sweat use. All carry SPF 50+ PA++++ ratings. The stick formats are particularly popular because they apply without the white cast of traditional cream sunscreens and can be re-applied over makeup without disrupting coverage.

Dr.G Sunscreen Guide: Sticks, Fluids, and Which Finish Is Right for Your Skin
Dr.G makes sunscreen in two physical formats (stick and fluid/lotion) and across three finish goals: pore control, brightening, and clear waterproof. All products in the lineup are rated SPF 50+ PA++++, which is the Korean regulatory maximum. Picking the right one comes down to skin type, application preference, and whether you need re-application over makeup. This guide maps each product to the use case it handles best.
SPF 50+ and PA++++ Explained
SPF (Sun Protection Factor) measures UVB protection; 50+ blocks approximately 98% of UVB rays. PA++++ is the Japanese and Korean standard for UVA protection, with four plus signs being the highest available rating. All Dr.G sun products in this collection carry both designations, meaning they offer broad-spectrum coverage against both burning rays (UVB) and aging rays (UVA). This is the same protection level required by Korean dermatologists for post-procedure sun avoidance.
Stick vs. Fluid: Which Format Suits You
Stick sunscreens apply via a glide-on wax base. They are easier to re-apply over makeup because you press rather than pour, they are portable and mess-free, and they tend to leave a more matte or satin finish. Fluid sunscreens provide more even full-face coverage in a single application, tend to feel lighter on the skin, and are better for the initial morning application layer. Many users combine both: a fluid for the morning base application and a stick for re-application during the day.
Pore Blur Series: For Oily and Large-Pore Skin
The Pore Blur Up Sun Stick (19 g) contains silica microspheres that fill the appearance of pores and absorb inter-day sebum. The finish is matte-to-satin rather than dewy. This is Dr.G's choice for anyone who finds most sunscreens make their skin look more oily or emphasize texture. Apply as the last skincare step before makeup, or re-apply directly over foundation during the day.
Brightening Tone Up: For Dull or Uneven Skin Tone
The Brightening Tone Up Sun Stick (17 g) uses light-scattering pigments to add an instant radiance boost while providing SPF 50+ protection. The tone-up effect is subtle, shifting the skin one to two shades lighter rather than providing the heavy coverage of a tinted moisturizer. Best suited to normal-to-dry skin or anyone who wants a light base before makeup or on no-makeup days. Oily skin may find the brightening pigments highlight texture over time.
Medi UV Ultra Series: High-Protection Derma Line
The Medi UV Ultra Sun Plus (50 ml) and Medi UV Ultra Up Sun Stick (25 g) are Dr.G's dermatologist-grade formulations designed for post-procedure skin, compromised barriers, or skin that reacts to fragrances and heavy filters. The fluid version is a lightweight lotion with a barely-there finish. The stick version covers targeted areas or acts as a mid-day top-up. The Medi UV Mild Line (50 ml) is a gentler variant in the same sub-range, suitable for sensitive skin that cannot tolerate even the Ultra formula.
Vita Clear Series: Waterproof and Vitamin-Enriched
The Vita Clear Waterproof Sun Stick (21 g) and Vita Clear Sun Serum (50 ml) are formulated for high-UV or water-exposure situations. The waterproof stick is resistant to sweat and incidental water contact, making it the right choice for outdoor sports, beach days, or commuting in heat. The Sun Serum pairs a serum-weight texture with SPF protection and vitamin actives for glow, a good option if you want to combine a vitamin serum step and sunscreen into one product on lighter makeup days.
Green Mild Up Sunstick: Green Tea Antioxidant Base
The Green Mild Up Sunstick (20 g) draws on Dr.G's green tea ingredient expertise. The antioxidant content from the tea extract is a complement to the chemical UV filters rather than a replacement. The mild designation means the formula is positioned for sensitive and reactive skin types within the regular-use range, sitting between the Medi UV derma line and the finish-focused Pore Blur and Brightening sticks.
Nice Buddy Sunstick: Compact Everyday Carry
The Nice Buddy Sunstick (14 g) is the smallest format in the lineup, designed for portability. At 14 g it fits easily in a pocket or small bag and is the most practical format for mid-day touch-ups when you are on the move. The formula is straightforward SPF 50+ PA++++; choose this when portability is the primary requirement.
How and When to Re-Apply
Korean dermatologists recommend reapplication every two hours in direct sunlight. Stick formats make this practical over makeup - press the stick directly onto skin and blend lightly with a clean finger or sponge. Fluid formats are better for the initial morning application; avoid re-applying a fluid over makeup as it will disrupt coverage. For indoor days with minimal direct sun exposure, a single morning application is generally adequate. For driving, position near windows, or outdoor time, the two-hour rule applies.
FAQ
Frequently asked questions
FAQ
Frequently asked questions
What SPF rating do Dr.G sunscreens carry?
All Dr.G sun products in this collection are rated SPF 50+ PA++++, which is the highest available broad-spectrum rating in the Korean cosmetics regulatory system. SPF 50+ blocks approximately 98% of UVB rays; PA++++ is the top tier of UVA protection.
Which Dr.G sun stick is best for oily or large-pore skin?
The Pore Blur Up Sun Stick is the most suitable choice for oily skin. It contains silica microspheres that absorb sebum and blur pore appearance, leaving a matte-to-satin finish rather than the dewy or shiny finish that many sunscreens produce on oily skin. The Green Mild Up Sunstick is a secondary option if your oily skin is also sensitive.
Is the Medi UV line suitable for sensitive or post-procedure skin?
Yes. The Medi UV Ultra and Medi UV Mild lines are designed for sensitive, compromised, or post-procedure skin. They are fragrance-free, use a gentler filter combination, and are formulated to avoid the stinging that some sensitive-skin users experience with regular SPF products. The Mild variant is the more conservative formulation if you are recovering from a chemical peel, laser, or similar treatment.
Is the Vita Clear Waterproof Sun Stick suitable for swimming?
The Vita Clear Waterproof Sun Stick is sweat-resistant and water-resistant under normal outdoor and sport conditions but is not the same as a purpose-built swim sunscreen that is tested for 40 or 80 minutes of water immersion. It is a good choice for the beach, pool-side, or water sports with intermittent water contact, but re-apply immediately after toweling off or extended submersion.
Can the Vita Clear Sun Serum replace my morning serum or is it an additional step?
The Sun Serum is primarily a sunscreen with serum-weight texture and vitamin actives added for a secondary benefit. It can functionally replace a vitamin C or brightening serum if you are simplifying your morning routine. However, if you use a treatment serum targeting a specific concern (peptides for elasticity, niacinamide for hyperpigmentation), keep that serum as a distinct step and apply the Sun Serum on top as your SPF layer.
Can I apply the Brightening Tone Up Sun Stick under foundation?
Yes. Apply the stick, blend lightly with fingertips, then let it set for about a minute before applying foundation. The tone-up pigments are compatible with standard foundation and will not disrupt the formula. Avoid heavy rubbing when applying foundation over the stick; a dabbing motion with a sponge gives cleaner results.
How do the Dr.G sun stick sizes compare for daily use vs. travel?
The 25 g Medi UV Ultra Up and the 21 g Vita Clear Waterproof sticks are the larger everyday formats that last a full month or more with daily use. The 19 g Pore Blur, 20 g Green Mild, and 17 g Brightening Tone Up are mid-range. The 14 g Nice Buddy is the most portable and is designed for mid-day re-application rather than as a primary all-day format. All are carry-on compliant for air travel.
Do Dr.G sunscreens leave a white cast?
Most Dr.G sun products in this range use chemical UV filters rather than mineral zinc oxide or titanium dioxide, which are the primary causes of white cast. The Pore Blur, Brightening, and Vita Clear sticks are designed to be virtually invisible on medium skin tones. The Medi UV line may leave a very slight sheen on very deep skin tones. No product in this collection uses a heavy mineral-only formula.
How often do I need to re-apply Dr.G sunscreen during outdoor activities?
Every two hours in direct sunlight is the standard guideline. For indoor environments with limited direct sun exposure, a single morning application is adequate. After swimming or heavy sweating, re-apply immediately regardless of elapsed time. The stick formats are practical for mid-day re-application over makeup without a brush or wipe.
What is the difference between Medi UV Ultra Sun Plus and Medi UV Mild Line?
The Ultra Sun Plus has a slightly richer formula designed for general sensitive or post-procedure use. The Mild Line uses a more pared-down ingredient deck for skin that reacts to a wider range of cosmetic ingredients, including some typically present in the Ultra formula. If you have had reactions to most sunscreens in the past, start with the Mild Line before trying the Ultra.
Can I use the Nice Buddy Sunstick as my primary daily sunscreen?
It works as a primary sunscreen if you apply enough product and blend thoroughly to cover the full face. The 14 g size means a 50 g-equivalent full-face application frequency will use through the stick faster than the larger formats. For daily full-face use, the 19 to 25 g sticks are more economical; the Nice Buddy is better used as a top-up stick during the day alongside a fluid primary application in the morning.
Is the Green Mild Up Sunstick safe for acne-prone skin?
The Green Mild Up Sunstick is formulated to be mild on sensitive and reactive skin, which overlaps with acne-prone types. The green tea extract provides anti-inflammatory support. It does not contain alcohol at high concentrations or fragrance, which are common acne triggers. That said, some acne-prone users find any wax-based stick format slightly more occlusive than a fluid; if you are prone to congestion, patch test on the chin or jaw before using across the full face.
