How to Use Clearstem Clearity (Plus Similar Mandelic Acid Serums)
Short answer: apply a thin layer of Clearity to clean, dry skin, leave it on for about ten minutes, then follow with a moisturizer, and use sunscreen the next morning. Patch test first and start slowly, because it blends several exfoliating acids.
How to use Clearstem Clearity, step by step
- Cleanse your face and pat it dry.
- Patch test the first time, behind the ear or on the jaw.
- Apply a thin layer of Clearity to the whole face, or to congested areas.
- Wait about ten minutes. Reviewers say blackheads soften if you leave it on for that time, and The Hive advises a ten-minute wait before moisturizer.
- Moisturize, for example with Hydraglow.
- Use sunscreen the next morning, such as Youaresunshine.
How often to use it
The sources we read do not give a schedule. A common approach for acid serums is to start with a couple of nights a week and increase only if your skin is comfortable. Stop and ease off if you feel stinging that does not settle or see flaking or redness.
Layering Clearity with other Clearstem products
Clearstem’s Cellrenew guide says to apply Clearity first, wait 10 to 15 minutes, then apply Cellrenew. The brand says Cellrenew helps skin tolerate stronger actives with less irritation. See Bounceback vs Cellrenew for the full order.
As a general rule, avoid stacking Clearity with other strong exfoliants or retinoids on the same night until you know how your skin reacts.
Who should be careful
Clearity combines mandelic, pyruvic, glycolic, lactic, malic and tartaric acids with soothing ingredients such as turmeric and green tea, plus witch hazel and citrus oils. A Substack reviewer had no irritation, but warned that people with a compromised barrier or rosacea may find it too stimulating. Our Clearity review covers the pros and cons.

Check each product’s directions, because acid strengths and ingredients differ.
Our take: use Clearity slowly and consistently, and give it a month before you decide. If a simpler serum appeals to you, one of the alternatives above may be enough. This is general information, not medical advice. If you have persistent or severe acne, ask a dermatologist.
