sum37 Sun Away: Full SPF Range Buying Guide

sum37 Sun Away is the brand's dedicated sun protection line, covering cushion CC formats, a solid sunstick, a serum-texture SPF, tinted and untinted sunblocks, and planning sets. With 14+ products, it is one of the more complete sun care ranges from a single Korean skincare brand.

The Sun Away format lineup

sum37 Sun Away covers five distinct sunscreen formats: CC cushion (15 g compact), solid sunstick (18 g), liquid serum (50 ml), watery sunblock (50 ml), and multi-effect sunblock (50 ml and 100 ml). Each format suits a different skin type, coverage preference, and use-case scenario - from base makeup with SPF to a bare-skin daily protector.

The CC formats provide light coverage alongside protection. The serum and watery formats are clear and makeup-compatible. The Tone Up Sunblock adds a brightening tint to the finish. The Multi-Effect Sunblock is the most versatile, combining protection with skincare-adjacent benefits from sum37's fermentation base.

Sun Away Cooling CC: the coverage plus SPF format

The Sun Away Cooling CC comes in 15 g standard and 15 g EX (updated formula). Both deliver tinted CC coverage alongside sun protection in a cushion format. CC creams correct tone and provide light coverage while functioning as sunscreen. The Cooling designation adds a temperature-reducing sensation on application.

The Breath Sun Away Cooling CC IEX Refill is the replacement puck for the IEX compact. At 15 g per compact, each cushion provides approximately 60-80 applications. The Cooling effect is noticeable on application and suits warm-weather use or skin that runs warm during the day.

Sun Away Velvet Sunstick 18 g: reapplication in seconds

The Velvet Sunstick 18 g is a solid-format SPF applicator used for quick reapplication over makeup. The stick format allows precise coverage on the nose, forehead, cheeks, and ears without spreading product across the face with fingers. At 18 g, it lasts several months of daily single-pass reapplication.

It is the most portable format in the Sun Away range, fitting in a pocket or small bag. The velvet name refers to the finish - a non-glossy, matte-adjacent surface that does not look wet or greasy over makeup.

Microactive Sun Serum 50 ml: the serum-texture option

The Microactive Sun Serum 50 ml delivers SPF protection in a water-light serum texture. It is the thinnest, fastest-absorbing format in the Sun Away range. It suits skin that reacts poorly to the heavier feel of conventional sunblock lotion, or users who want a sunscreen that does not change the texture of the skin before makeup.

The Microactive naming refers to micro-encapsulated SPF particles in sum37's formula technology. Micro-encapsulation can improve SPF filter stability and reduce the chalky or white-cast residue common in some SPF products.

Sun Away Cooling Watery Sunblock EX 50 ml

The Cooling Watery Sunblock EX 50 ml is a liquid-format, clear sunblock that absorbs like a lightweight lotion. The watery texture is preferred by oily and combination skin types because it does not sit heavily on the surface. The Cooling formulation reduces heat sensation on contact, which is particularly useful in summer or in hot climates.

At 50 ml, it provides a full two months of daily face application at the standard three-finger dosage for adequate SPF coverage.

Sun Away Multi-Effect Sunblock: the versatile daily SPF

The Multi-Effect Sunblock is available in 50 ml and 100 ml Planning sizes. The Multi-Effect designation indicates the formula functions as sunscreen, skincare (moisturizing, fermentation-based), and base. It reduces the total number of products needed in a morning routine when applied as the final step before makeup or going out.

The 100 ml AD Planning size is the highest-volume format in the Sun Away range and provides the best value per ml. It suits daily users who apply sunscreen to face and neck every morning and run through 50 ml bottles faster than is convenient.

Sun Away Tone Up Sunblock 50 ml: the brightening option

The Tone Up Sunblock 50 ml adds a purple or violet correcting tint to the formula, which neutralizes sallowness and gives skin a brighter, more awake appearance when worn before makeup or on its own. Tone-up products are common in Korean sun care as a light base step that improves how the final complexion looks without the full coverage of a foundation.

It is best worn as the last skincare step before foundation or cushion, or alone on no-makeup days when a groomed finish is needed. The tint blends to translucent on most skin tones within a minute of application.

FAQ

Frequently asked questions

  • skinsli carries 14+ sum37 Sun Away products including the Cooling CC cushion (15 g standard and EX), Velvet Sunstick 18 g, Microactive Sun Serum 50 ml, Tone Up Sunblock 50 ml, Cooling Watery Sunblock EX 50 ml, Multi-Effect Sunblock EX 50 ml, the 100 ml AD Planning set, and the Cooling CC IEX Refill.

  • The Cooling Watery Sunblock EX 50 ml and the Microactive Sun Serum 50 ml are the lightest textures and suit oily skin best. The Velvet Sunstick is also matte-finish and non-greasy for reapplication over makeup. The CC cushion adds coverage but can feel slightly heavier on oily skin in warm weather.

  • Tone Up sunblocks use a violet-tinged formula that neutralizes yellow or sallow tones. They work most visibly on medium and lighter skin tones where the color-correcting contrast is noticeable. On darker skin tones, the effect is subtler but the finish is still brighter than a standard clear sunblock. The tint blends to near-translucent within one to two minutes on most tones.

  • Yes. The solid-stick format does not drag or smear foundation when applied with a light glide. Press or pat with a fingertip after application to blend. The velvet finish does not add shine, making it compatible with matte and natural-finish makeup bases.

  • The EX (Extended) version is an updated formula iteration of the standard Cooling CC. It incorporates formula refinements to coverage, cooling intensity, or SPF filter stability. Both are 15 g cushion compacts. The EX is the more current generation and generally available alongside or replacing the original.

  • Yes. The 100 ml AD Planning provides more than double the uses at a lower cost per ml than the 50 ml. For daily users applying sunscreen to the face and neck every morning, the 100 ml covers approximately four months and reduces repurchase frequency significantly.

  • The Microactive Sun Serum uses micro-encapsulated SPF technology which reduces the white-cast effect common in some chemical and mineral filters. The serum texture is clear and absorbs quickly. White cast is significantly less than conventional physical SPF creams, though a small amount may be visible on the deepest skin tones.
