Product FAQ

Is this safe for sensitive skin?

Many can tolerate it when introduced gradually—start every-other-day or patch test first. Avoid layering other strong actives simultaneously.

Can I build this into a layered glow routine?

Yes, pair with hydrating or antioxidant toners. Use moisturizer afterwards—and always apply SPF.

When will I see brightening results?

Visible glow may appear within 1 week; more noticeable fading of spots typically appears within 4–6 weeks of consistent use.

I have used a few products before and tbh they're so good, i noticed the visible change on my skin. I would love to use those products again.

Looove my order as always!!! I like how they ship everything out really fast and this is my go to online store for most of the popular Korean skincare products. I highly recommend TER Glow to all the girlies who love K-beauty out there

I’ve been using a few products from Terglow and honestly, I’m loving them so far. My skin feels a lot more hydrated and it doesn't leave that greasy feel on your face. Like I said, it's not too heavy or greasy and they actually feel like they’re doing something. Packaging is also really clean and simple, which I like fast shipping too! Would order again.

I recently discovered TER, and it's quickly become my go-to place for skincare! The selection is fantastic — they carry a wide range of trusted brands along with some hidden gems that you won’t find at big-box stores. Whether you're looking for something to hydrate, treat acne, brighten dull skin, or just maintain a solid routine, they have options for every skin type and concern.

T.E.R is my go-to destination for premium Korean and Japanese skincare products. Their curated selection features top-quality items that cater to various skin types and concerns. The website is user-friendly, and their customer service is exceptional—prompt, helpful, and always professional. Shipping is fast, and products arrive well-packaged. I've discovered some of my favorite skincare gems here, and I appreciate their commitment to authenticity and quality. Highly recommend T.E.R to anyone looking to elevate their skincare routine.
