Formerly Beta-Clarity BHA Drops. Renew Serum is back with the same trusted formula, now in an improved airless pump for more precise, effective application.

What It Does

An advanced overnight clarifying treatment designed to restore balance, refine texture, and support healthy skin renewal. Powered by a targeted trio of retinol, glycolic acid, and salicylic acid, this formula helps gently exfoliate, balance excess oil, and clear congested pores for a visibly smoother, brighter complexion.

Key Actives

  • Retinol. A vitamin A derivative that supports cell renewal, softening the look of fine lines, pores and uneven tone. This is a level 1 retinol serum.
  • Glycolic acid. An alpha hydroxy acid (AHA) with a small molecule, working on texture and uneven tone at the surface.
  • Salicylic acid. A beta hydroxy acid (BHA). Oil-soluble, so it clears congestion from inside the pore.
  • Niacinamide. A form of vitamin B3 that supports the moisture barrier and helps balance oil.
  • Panthenol and honeysuckle extract. Added to keep the formula comfortable alongside three actives.

Clinical results show visible improvement after just one week, with 93% reporting reduced excess oil and 87% a reduction in the appearance of pores. With continued use, 90% reported brighter, healthier-looking skin and smoother texture after 30 days.

Who It Suits

Perfect for all skin types except extremely sensitive.

Key Benefits

  • Smoothing: Gentle exfoliation from salicylic and glycolic acids helps refine skin texture, reducing the appearance of fine lines and pores.
  • Clarifying: Retinol and salicylic acid refine skin and help eliminate impurities, rebalancing excess oil, promoting a clearer complexion.
  • Brightening: Retinol and hydroxy acids support cell renewal, helping to improve tone and reveal brighter, more even-looking skin.

How to Use

  1. Prep skin by cleansing and toning. Allow skin to dry fully.
  2. Apply 4-6 drops to the entire face, avoiding the eyes. This level 1 retinol serum can be used 2-7 nights per week.
  3. Once the serum has fully absorbed, follow with moisturiser.

Three actives in one bottle is efficient and it is also easy to overdo. Two nights a week to start, and build only once your skin is quiet on that. The people who get the best result from this are the ones who went slowest at the beginning.

Key actives

Active What it does Why we use it
RetinolRetinol Supports cell renewal, helping refine texture and the look of tone. The reason this serum works on texture as well as congestion, which acids alone rarely manage.
Glycolic acidGlycolic Acid An alpha hydroxy acid that exfoliates the surface and softens the look of fine lines. Handles the surface while salicylic acid handles the pore.
Salicylic acidSalicylic Acid A beta hydroxy acid that clears congestion from inside the pore and balances oil. Completes the trio, so one step covers surface, pore and renewal.
