Blemish-prone skin is a surprisingly common issue for adult men - and most products that address it are either too harsh, too clinical, or designed for teenagers. The Doers of London Clear Serum is different. It's a targeted treatment serum built around 12% Niacinamide and 5% Zinc PCA, two of the most evidence-backed ingredients for controlling excess oil, combating acne-causing bacteria, refining pores, and evening out uneven skin texture - all without stripping the skin's natural balance.
This isn't a spot treatment. It's a daily skin rebalancer.
Who's It For
- Men with oily, acne-prone, or blemish-prone skin who want a targeted daily treatment
- Anyone dealing with enlarged pores, uneven skin texture, or recurring breakouts
- Guys who want a science-backed serum without the clinical-brand price tag
- Men looking to add an active treatment step between cleanser and moisturizer
Key Benefits
- 12% Niacinamide reduces redness, minimizes enlarged pores, refines skin texture, and diminishes dullness
- 5% Zinc PCA balances sebum production and actively controls acne-causing bacteria
- LentiMyrt HF (fermented Myrtle and Lentisk extract) strengthens the skin barrier and modulates the skin microbiome
- Gotu Kola soothes and supports healthy skin recovery
- Free from parabens, PEGs, SLS/SLES, silicones, mineral oils, synthetic fragrance Vegan and cruelty-free
- Dermatologically tested
How It Works
Niacinamide — a form of Vitamin B3 — works across multiple pathways simultaneously: reducing inflammation, calming redness, tightening the look of enlarged pores, and improving overall skin tone and texture. At 12% concentration, it's formulated to deliver meaningful clinical results. Zinc PCA brings zinc's antibacterial and sebum-regulating properties together with L-PCA's ability to strengthen the skin's moisture film — so you get less oil and less bacterial activity without dehydrating the skin. LentiMyrt HF, derived from Myrtle and Lentisk through a hyperfermentation process, boosts the skin's antioxidant defenses and supports a healthier skin microbiome at the source.
Key Ingredients
-
Niacinamide (12%) – A naturally occurring Vitamin B3, formulated at high concentration to reduce redness, minimize pores, refine texture, and target blemish-prone skin.
-
Zinc PCA (5%) – A synergistic combination of zinc and L-PCA; zinc controls sebum production and bacteria that cause acne, while L-PCA strengthens the skin's moisture barrier.
-
LentiMyrt HF – A fermented extract of Myrtle and Lentisk that raises the skin's antioxidant defenses and positively modulates the skin microbiome.
-
Gotu Kola (Centella Asiatica) – Soothes and calms the skin while supporting the barrier and promoting healthy skin recovery.
How To Use
- Cleanse your face and pat dry.
- Apply a few drops of serum to your fingertips and gently press into the skin.
- Allow to absorb fully before applying moisturizer.
- Use as needed - not necessarily daily; assess your skin's response.
- For best results, start with the Facial Cleanser to prep the skin.
Why MASC Recommends This
The Clear Serum is one of those products where the formulation decisions are genuinely impressive. Getting Niacinamide at 12% and Zinc PCA at 5% in a clean, fragrance-free formula at this price point is uncommon. It's a legitimate treatment serum, not a marketing exercise. We recommend it to any man dealing with recurring breakouts, oily skin, or uneven texture who wants an active solution that doesn't require a prescription.
