Glycolic Acid

Glycolic Acid is a superstar Alpha Hydroxy Acid (AHA) derived from sugar cane. Because it has a small molecular size, it penetrates the skin effectively to encourage cell turnover.It sheds dull, flaky layers to reveal smoother texture and a brighter tone. It’s like dusting off a window to let the light in.

It comes down to your skin goals and the product format.

• Night Renewer is a cream focused on AHAs (10% Glycolic). It’s best for smoothing surface texture, fading dark spots, and moisturizing. Think of it as a "polish and hydrate" step.
• Super Smooth is a serum that combines AHAs with BHAs (Salicylic Acid). It works on the surface and inside the pore. Choose this if you are dealing with blackheads, acne, or stubborn congestion alongside rough texture.

They are sibling exfoliators with different specialties.

• AHA (Glycolic, Lactic): Water-soluble. Works on the surface to smooth roughness and brighten tone.
• BHA (Salicylic): Oil-soluble. Dives deep into the pores to clear out oil and debris.

Night Renewer is pure AHA power; Super Smooth gives you the best of both worlds.

We recommend picking one for your nightly routine rather than doubling up. Using two potent exfoliators at once can overstrip your moisture barrier and lead to irritation. If you love both, you can alternate nights or use Super Smooth during breakout-prone weeks and Night Renewer when you need extra moisture and smoothing.

You might feel a momentary tingle—we call it the "active fizz"—especially with Night Renewer’s 10% concentration. This is normal and usually subsides quickly. Both formulas are buffered with soothing ingredients (like Vitamin E and Hyaluronic Acid) to keep irritation in check. However, if you feel a persistent burning sensation, rinse it off.

We generally advise against using exfoliators and retinoids (like Moonlight) at the exact same time. It’s often too much stimulation for the skin. Instead, try "Skin Cycling": use your exfoliator (Night Renewer or Super Smooth) one night, and your retinoid the next.

Yes, but split them up. Use Glow Maker (Vitamin C) in the morning to protect your skin, and use Night Renewer or Super Smooth in the evening to resurface it. This "AM Protect / PM Repair" rhythm is a dermatologist favorite.

Yes, absolutely. Exfoliating strips away the dead layer of skin cells, making your fresh, new skin more sensitive to UV light. Using AHAs or BHAs without sunscreen is like taking two steps forward and one step back. Always finish your morning routine with SPF 30+.

Start slow.

• Beginners: Use 2–3 times a week.
• Pros: If your skin tolerates it well, you can build up to every other night.
• Note: Because Super Smooth contains BHA, it can be slightly drying for some, so monitor your hydration levels.

Night Renewer (Cream): Cleanse → Tone (optional) → Night Renewer. (If you have very dry skin, you can layer a thicker moisturizer on top after 10 minutes).

Super Smooth (Serum): Cleanse → Tone (optional) → Super Smooth → Moisturizer.

Super Smooth is likely your better match. The addition of Salicylic Acid (BHA) helps de-gunk pores and reduce the appearance of blemishes, while the AHAs fade the look of post-acne marks.

Because Super Smooth clears out pores, you might experience a "purge"—a temporary phase where congestion rises to the surface faster than usual. It typically clears up within a few weeks, leaving you with much clearer skin. Night Renewer causes less purging as it focuses more on surface polish, but it can still happen as cell turnover speeds up.
