Ingredients
Alpha-Hydroxy AcidsChemical Exfoliation · Pore Decongesting · Sebum Regulating
Alpha-Hydroxy Acids are a chemical exfoliant which exfoliate the top layers of the skin, offering a variety of benefits. They are mostly derived from plant-based sources. Some of the most common AHAs are Glycolic Acid, Lactic Acid, Citric Acid, Mandelic Acid and Malic Acid. Depending on the type of AHA, they can reduce dullness, even skin tone, reduce pigmentation, tighten pores, stimulate collagen production, hydrate the skin and offer antioxidant protection. AHAs are generally less irritating and drying to the skin as they are water-soluble.Poly-Hydroxy AcidsChemical Exfoliation · Pore Decongesting · Sebum Regulating
Poly-Hydroxy Acids are a chemical exfoliant which exfoliate the top layers of the skin. However unlike AHAs & BHAs, they consist of larger molecules so they tend to sit on the surface of the skin for longer and penetrate slowly. Therefore, they are particularly good for more sensitive skins. As well as sloughing off dead skin cells, revealing a smoother, clearer and brighter complexion; this acid is also a fantastic hydrator.Beta Hydroxy AcidChemical Exfoliation · Pore Decongesting · Sebum Regulating
Beta Hydroxy Acid is a chemical exfoliant which penetrates deeply into pores to dissolve debris and dead skin cells. Because BHAs are oil-soluble, anti-bacterial & anti-inflammatory, they are particularly adept at treating active, inflamed and infected acne; even cystic acne. Also known as Salicylic Acid, this powerful ingredient is great at sebum-regulating the skin, reducing pores, lightening hyperpigmentation, fighting bacteria and easing inflammation.Vitamin B3 (Niacinamide)Anti-Inflammatory · Skin Barrier Strengthening

It helps to strengthen skin barrier function and increase water retention by increasing natural ceramide production.

Niacinamide is also a potent antioxidant with protective and brightening properties helping to restore skin's natural glow.SulphurChemical Exfoliation · Pore Decongesting · Sebum Regulating
Sulphur is a chemical element found in various minerals, typically in the form of sulphide and sulphate compounds. It is valued for its keratolytic properties, which means it can soften keratinóthe protein that makes up the skin, hair, and nails. This softening action helps to smooth rough or hardened skin and facilitates the removal of superficial layers of the epidermis. By doing so, sulphur prepares the skin to better absorb and benefit from other skincare ingredients applied afterward. This makes it a useful component in skincare formulations aimed at promoting smoother, clearer, and more radiant skin.Onion, Myrrh & Myrtle ExtractSebum Regulating · Purifying · Antioxidant
Unique to Biologique Recherche, the "Complex of Onion, Myrrh & Myrtle" has incredible astringent (tightening), purifying, antioxidant and soothing properties; which is very effective for an oilier complexion combatting sebum-regulation, acne or congestion.Magnesium ChlorideBrightening · Purifying · Skin Barrier Strengthening
