Principia GL-01

Principia GL-01 is a Brazilian dermocosmetics facial cleansing gel designed for a fresh, balanced cleanse—especially when skin feels oily, congested, or dull. Formulated with 2% salicylic acid (BHA) and 5% glycerin, it helps lift daily impurities, refine the look of pores, and leave skin feeling soft and comfortable—without the heavy, tight “over-cleansed” finish many foaming cleansers can cause.

Product highlights

Salicylic Acid (2% BHA): A beta-hydroxy acid with antibacterial and antifungal properties. Helps exfoliate the outer layer of the skin by removing dead cells, supports oil control, and helps reduce the appearance of blackheads and blemishes. Its keratolytic action may also help improve skin permeability, supporting better integration of complementary skincare actives. Glycerin (5%): A hydrophilic organic compound widely recognized as a highly effective humectant. Helps attract and retain water to support hydration and comfort. Beyond surface moisturization, glycerin can penetrate the skin barrier and help maintain hydration in deeper layers for longer-lasting softness. Cleansing Surfactants (Tensoativos): Ingredients designed to break down and emulsify oils and debris, suspending particles so they rinse away easily with water. Surfactants may be classified as cationic, anionic, non-ionic, or amphoteric depending on the ions they form in aqueous solution—helping formulators balance cleansing performance with skin feel.

Allergen warnings / cautions: For external use only. Discontinue use if irritation occurs. Avoid direct contact with eyes. If you are sensitive to exfoliating acids, start once daily and increase as tolerated. Use sunscreen during the day when using exfoliating acids in your routine. Principia is a Brazilian dermocosmetics brand founded in 2020 in São Paulo with a clear mission: democratize high-performance skincare through science-backed formulas, radical ingredient transparency, and fair, accessible positioning. Instead of relying on hype, Principia focuses on what matters most for results-driven routines— active ingredients at disclosed percentages, straightforward formulations, and a minimalist, clinical aesthetic designed for everyday use.

Product information

Who can use Principia GL-01?

It is suitable for all skin types and is especially popular for oily or blemish-prone routines due to salicylic acid.

Can I use it twice a day?

The brand indicates daily AM/PM use. If your skin feels dry or tight, reduce to once daily and pair with a hydrating moisturizer.

Does it help with blackheads and blemishes?

Salicylic acid may help keep pores clearer and reduce the look of blackheads and blemishes with consistent use, but results vary.

Can I use it with other actives (like vitamin C or retinoids)?

Many routines combine it with other actives. If your skin is sensitive, introduce one active at a time and avoid over-exfoliation.
