Acne prone

Will this help with acne scars and dark spots?

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.

Can I use it if I am acne-prone?

Yes. The formula is designed to set clean and layer with sunscreen and makeup. Patch test and adjust frequency to your tolerance.

Will this cause purging?

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.

Where does it go in my routine?

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.

before and after

Makeup-friendly

Will it pill under makeup?

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.

Can I mix it with moisturizer?

Yes. Add 3–5 drops into Infinite Aura Moisturizer for a single step. This also helps minimize pilling risk.

How long should I wait before makeup?

About 60 to 90 seconds so the serum sets. Then apply moisturizer, SPF, and makeup.

Can I use it with niacinamide or sunscreen filters?

Yes. THD Vitamin C is oil-soluble and generally layers well. Always patch test when combining actives.

Does it stain or oxidize on skin?

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

before and after

Are AHAs good for texture?

Yes. AHAs help remove dull surface cells and improve the look of texture and tone.

Is lactic acid gentle?

Lactic is considered one of the gentler AHAs and also has hydrating properties.

Can I use it every day?

Many use it nightly. Start 2 to 4 nights per week and adjust as your skin allows.

Do I need sunscreen?

Yes. AHAs can increase sun sensitivity. Use daily SPF.

Can I use Vitamin C and AHA together?

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.

How long until I see a glow?
