Sensitive skin
Acne prone
For many, Vitamin C and AHAs are used to improve the look of post-inflammatory hyperpigmentation with consistent use and sun protection. Results take time.
Yes. The formula is designed to set clean and layer with sunscreen and makeup. Patch test and adjust frequency to your tolerance.
You can alternate nights to reduce the chance of irritation. Introduce one active at a time and use daily SPF.
Some users may notice temporary increase in flaking or tiny bumps as AHAs lift dull surface cells. If skin feels irritated, reduce to 2 to 3 nights per week and increase slowly. Always patch test and keep layers simple.
Apply after cleanse and before moisturizer. In the morning use serum → moisturizer → SPF. At night alternate serum nights with acne treatment nights if you use stronger actives.
Makeup-friendly
It is designed to be non sticky and to layer clean. Let it set before SPF and makeup. Use thin layers and press product in. If you find it to be peeling it means you’ve applied too much and your skin can’t absorb anymore.
Yes. Add 3–5 drops into Infinite Aura Moisturizer for a single step. This also helps minimize pilling risk.
About 60 to 90 seconds so the serum sets. Then apply moisturizer, SPF, and makeup.
Yes. THD Vitamin C is oil-soluble and generally layers well. Always patch test when combining actives.
Allow full dry-down and use SPF. Store the bottle away from heat and light to maintain freshness. General Vitamin C storage best practices apply.
AHA resurfacing
Yes. AHAs help remove dull surface cells and improve the look of texture and tone.
Lactic is considered one of the gentler AHAs and also has hydrating properties.
Many use it nightly. Start 2 to 4 nights per week and adjust as your skin allows.
Yes. AHAs can increase sun sensitivity. Use daily SPF.
Skin brightening
Yes, this serum pairs THD Vitamin C with a gentle AHA trio inside one formula for smooth, bright results without a harsh feel. Patch test if you are new to acids.
Many users notice immediate radiance from hydration and smoothing; even-tone benefits build with consistent daily use.

I’ve always heard really good things about this serum and when I used it on myself, my skin has and really glow! Best glow serumTo be honest,
Yesss! The glow is glowing We’re so happy you finally tried it and saw the magic for yourself!
Holly knew what she was doing when she made this serum!!!! Kay’s glow CLEARED my hormonal, fungal, and cystic acne. I have struggled for years and using this paired with the limpya cleansing balm made a huge difference. Not only is my skin clear but also super glowy!!! I recommend this to anyone struggling to clear their skin or wanting glowy skin. I started to notice a difference in my skin in just a few weeks and only took a couple months to fully clear. My sensitive skin lovessss Boho products!!
Okay but this review = chills 😍 Clear, glowy, confident skin is what it’s all about! So happy Kay’s Glow and the Cleansing Balm became your power pair
Best skincare purchase I've ever made. I just bought my second bottle of this glow magic. Kay's Glow Serum will always be a part of my skincare routine. Thank you, Holly and Kay.
We’re so honored! 💛 “Glow magic” on repeat sounds like the perfect routine. Thank YOU for making Kay’s Serum a forever fave ✨
I have always hated my skin and was so self-conscious , always feeling like I had to wear concealer and foundation going out. I am almost finished with my first bottle and now I love my skin! I even get compliments about the way it looks! I no longer feel the need to wear makeup most of the time! It has really boosted my confidence! I can honestly say this is the most comfortable I've felt since using Kay's glow serum!!! It has helped me stick with a routine. I literally love getting to use it morning and night, smells amazing and the glow is legit!!!!
This is EVERYTHING Hearing that Kay’s Glow Serum boosted your confidence and helped you love your skin makes our hearts so full. Your glow is inspiring ✨
I'm absolutely obsessed with Kay's Glow Serum. Not only does it smell amazing but leaves your skin feeling so silky and hydrated! I've never used a product I've loved more. I suffer from minor hormonal acne and have had some random congestion in my skin and the glow serum completely healed that. Honestly, everyone should be using this product!
Obsessed with this review! 😍 We’re so happy Kay’s Glow Serum is giving you silky, hydrated, clear skin. Acne + congestion? No match for the glow ✨
