The Benefits

Chemical Exfoliation

Chemical exfoliation uses acids to dissolve the "glue" holding dead skin cells together, promoting skin cell turnover and replacing old cells with new, healthy ones. Acids like AHAs, BHAs, and PHAs not only help shed skin but also offer benefits like brightening, clarifying, and anti-ageing, depending on the type used.

Purifying

Purifying your skin means removing impurities, reducing excess oil, and deep cleansing to minimise a greasy or shiny appearance and prevent breakouts. This process leaves your skin clearer, more balanced, and looking fresh.

Complexion-Evening (Anti-Blotchiness)

Evening skin tone is all about reducing blotchiness and achieving a more uniform complexion. Skincare products designed for this purpose use a blend of active ingredients, including soothing agents, anti-pigmentation compounds, antioxidants, and skin-restoring elements. These ingredients work together to diminish redness, inflammation, and pigment irregularities caused by inflammation, while also strengthening and protecting your skin against environmental irritants and future damage. This promotes healing and resilience, leaving your skin more balanced, radiant, and beautiful.

Pore Tightening & Minimising

Pore minimising involves reducing the appearance of enlarged pores. Enlarged pores often result from excess oil production and accumulated impurities, which stretch them over time. ageing also plays a role, as reduced skin elasticity makes pores more visible. Pore-minimising formulas tackle these issues by regulating oil production and boosting collagen and elastin to enhance skin elasticity. This helps pores return to their natural, less noticeable shape, giving your skin a smoother, more refined look.

Brightening

Brightening your skin means restoring its natural glow. One of the best ways to do this is through exfoliation. By exfoliating, you promote faster skin cell turnover, replacing old, damaged cells with fresh, radiant ones. This keeps your skin looking vibrant and healthy.

Anti-Pigmentation

Dealing with pigmentation means targeting melanin overproduction to reduce dark spots and prevent new ones. Melanin production can be triggered by UV exposure, pollution, hormonal changes (like during pregnancy), and inflammation (from acne or cuts). This excess pigment is then transferred to surrounding cells in epidermis called keratinocytes, which then moves to the skin's surface, causing visible dark spots.

To treat hyperpigmentation, a personalised and consistent approach is needed. Our anti-pigmentation products include lightening agents to block tyrosinase (the enzyme that creates melanin), antioxidants to fight free radicals, and ingredients to speed up skin cell turnover, removing pigmented cells. Using broad-spectrum sun protection is crucial to prevent new pigmentation during treatment.

Sebum Regulating (Mattifying)

Sebum regulation involves normalising oil production in your sebaceous glands to reduce shine, oiliness, and breakouts, restoring your skin's natural balance. Overactive sebaceous glands can be triggered by internal factors like genetics, hormonal changes, and stress, as well as external factors such as climate, pollution, and diet. Excessive sebum production can lead to enlarged pores, acne, and an oily, shiny appearance. Effective sebum regulation means using skincare products that balance oil levels without over-drying your skin, helping you achieve a clearer, more matte complexion.

Regenerating

Regenerative benefits work to restore and renew your skin at a cellular level. By stimulating cell turnover and boosting collagen and elastin production, they help repair damage, diminish fine lines and wrinkles, and improve overall skin texture. The result is a rejuvenated, firmer, and more youthful complexion that radiates vitality.

Anti-Bacterial

Anti-bacterial action targets and inhibits the growth of bacteria on your skin's surface. Anti-bacterial ingredients work by disrupting essential bacterial processes like cell wall synthesis or protein production, reducing the risk of skin infections and inflammation. They are especially effective for treating acne by controlling the acne-causing bacteria known as Cutibacterium acnes (C. acnes). This anti-bacterial action helps diminish imperfections, prevent new breakouts, and reduce irritation, giving you clearer, healthier skin.

Penetration Enhancing

Penetration enhancing in skincare involves advanced technologies designed to boost the absorption and effectiveness of active ingredients deep within your skin's layers. These enhancements ensure that skincare products deliver their powerful benefits precisely where they're needed most. By overcoming the common issue of low permeability in many effective ingredients, penetration enhancers maximise the unique benefits and visible results of your skincare routine.

Active Ingredients

Vitamin B3 (Niacinamide)

Vitamin B3 also known as Niacinamide, is versatile and highly effective ingredient with many benefits. It helps to strengthen skin barrier function and increase water retention by increasing natural ceramide production. It's anti-inflammatory and sebum regulating properties soothe, repair and balance irritated, weakened and acne prone skins. Niacinamide is also a potent antioxidant with protective and brightening properties helping to restore skin's natural glow.

Onion, Myrrh & Myrtle Extract

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.

Sulphur

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.

Alpha-Hydroxy Acids

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 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 Acids

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.

Magnesium Chloride

Magnesium Chloride contains astringent properties, but also promotes skin regeneration by increasing the amount of collagen and elastin fibres in the dermis.

Beta-Hydroxy Acids

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.

Cider Vinegar

Cider Vinegar is extracted from fermented apples and contains high concentrations of fruits acids. Particularly potent in Acetic Acid, Citric Acid and Malic Acid; Cider Vinegar contains powerful exfoliating, purifying and renewing properties. High in Polyphenols, this ingredient also has significant antioxidant effects, combatting damageing photo-induced free-radicals.

Spotlight

Physical & Chemical Exfoliation

Physical and chemical exfoliation are two popular techniques for removing dead skin cells and promoting a healthier, more radiant complexion. Each method offers unique benefits and targets skin concerns differently, making them key components in any effective skincare routine. Exfoliation helps to improve skin texture, unclog pores, and enhance the absorption of skincare products, leading to smoother, brighter skin. Physical exfoliation offers immediate results, while chemical exfoliation promotes deeper, longer-lasting effects without the risk of physical irritation. Physical exfoliation involves the use of scrubs, brushes, or cloths with granules that manually slough off dead skin cells from the surface. This method provides instant smoothness but can sometimes cause micro-tears, making it less suitable for sensitive skin types. Chemical exfoliation, on the other hand, employs acids (like AHAs, BHAs) or enzymes to dissolve dead skin cells at a deeper level. This process promotes cell turnover, enhances the skin’s natural renewal process, and helps to reduce the appearance of fine lines, pigmentation, and dullness without abrasive action, making it gentler for sensitive skin. Physical exfoliation delivers a quick, refreshed feel, but those with sensitive skin might find it too abrasive. Chemical exfoliation gradually reveals smoother, brighter skin with regular use, and is generally better suited for those seeking a gentler approach with deeper results. Users often notice improved skin clarity, reduced congestion, and an overall glow. Both exfoliation methods have their place in a skincare routine, offering tailored solutions depending on skin type and needs. By choosing the right type of exfoliation, you can achieve a smoother, more radiant complexion that feels fresh, revitalised, and renewed, enhancing your overall skin health and appearance.

    The best solution for me.

    I have been using the P50 Lotion for over two years and so far this has been the best solution for me. I used it daily to get my rosacea under control and then every other day to maintain. My skin is feeling great and my red spots have disappeared. It is quite pricy but lasts a long time so I don't need to order it too frequently.

    Life changing for me

    I have struggled with adult acne for the longest time. Had tried all different brands and Korean skincare. I was hesitant spending this much money on a toner but I do not regret it. No active acne within 3 days and slowly the marks are also fading away. I will not stop using this
