Skincare Ingredients
Every ingredient explained. Science-backed. No fluff.
A glycosylated form of hydroquinone that inhibits tyrosinase — the enzyme responsible for melanin production — without the cytotoxicity or regulatory concerns associated with hydroquinone itself. Effective, stable, and suitable for all skin types seeking a safer approach to brightening.
A naturally occurring dicarboxylic acid with anti-inflammatory, antibacterial, and brightening properties. One of the few actives safe for rosacea-prone and sensitive skin, and among the most well-researched ingredients for melasma and post-inflammatory hyperpigmentation.
A meroterpene compound derived from the seeds and leaves of Psoralea corylifolia. Clinically shown to upregulate retinol-like gene pathways in the skin without the irritation associated with retinoids. Effective for aging, hyperpigmentation, and texture — and safe for sensitive skin and during pregnancy.
An oxidizing antimicrobial agent that kills Cutibacterium acnes (formerly P. acnes) directly and without risk of antibiotic resistance. One of the most effective and well-studied OTC acne treatments available. Particularly suited to inflammatory and bacterial acne.
A botanical extract with potent anti-inflammatory and wound-healing properties. Centella asiatica soothes reactive skin, repairs the barrier, and supports collagen synthesis, making it a staple ingredient for sensitive and acne-prone skin types.
Lipids that naturally comprise roughly 50% of the skin's outer barrier. Topical ceramides replenish depleted barrier lipids, restore moisture retention, and reduce sensitivity and irritation. The most foundational ingredient category for barrier health and repair.
A plant-derived phenolic antioxidant that neutralizes free radicals and dramatically boosts the stability and efficacy of vitamins C and E. The cornerstone of the classic CE Ferulic antioxidant combination used in professional-grade photoprotective serums.
The smallest and most penetrating alpha hydroxy acid (AHA). Glycolic acid exfoliates the skin surface by dissolving the bonds between dead skin cells, improving texture, fading hyperpigmentation, and stimulating collagen production. Its small molecular size makes it the most effective AHA for deeper skin-renewal benefits.
A naturally occurring polysaccharide that can hold up to 1000 times its weight in water. Hyaluronic acid is one of the most effective and universally tolerated hydrating ingredients in skincare, working for every skin type and pairing seamlessly with virtually all actives.
A naturally occurring acid derived from fungi that inhibits melanin production at the source. Kojic acid is a targeted brightening ingredient used to fade hyperpigmentation, dark spots, and melasma without the harsh bleaching effects of older alternatives.
The gentlest AHA exfoliant, with a larger molecular size than glycolic acid that makes it ideal for sensitive and dry skin types. Simultaneously exfoliates and hydrates, making it one of the most beginner-friendly chemical exfoliants available.
The largest alpha-hydroxy acid molecule, derived from bitter almonds. Mandelic acid exfoliates gently and brightens effectively, making it the preferred AHA for sensitive skin types, acne-prone complexions, and deeper skin tones where aggressive exfoliation can trigger post-inflammatory hyperpigmentation.
A form of vitamin B3 that strengthens the skin barrier, reduces inflammation, and regulates sebum production. One of the most versatile and well-studied active ingredients in modern skincare.
A provitamin form of vitamin B5 that deeply hydrates, accelerates barrier repair, and soothes irritated skin. Panthenol is one of the most well-tolerated and multi-functional moisturizing ingredients available, effective across all skin types and compatible with virtually every other active in skincare.
Short chains of amino acids that act as signaling molecules in the skin, stimulating collagen and elastin production and supporting structural repair. A broad category covering dozens of distinct peptide types, each with specific mechanisms. An effective, low-irritation approach to anti-aging skincare.
The gold standard anti-aging ingredient. Retinol is a vitamin A derivative that accelerates cell turnover, stimulates collagen synthesis, and treats acne, hyperpigmentation, and fine lines. Decades of clinical research back its efficacy.
A beta hydroxy acid (BHA) derived from willow bark. Unlike AHAs, salicylic acid is oil-soluble, allowing it to penetrate into pores and dissolve the sebum and debris that cause blackheads, whiteheads, and acne. The leading OTC ingredient for blemish-prone skin.
A multifunctional ingredient derived from snail secretion that hydrates, supports wound healing, improves skin texture, and reduces the appearance of acne scarring. One of the most universally tolerated actives in skincare.
A stable, plant-derived hydrocarbon that closely mimics the skin's own natural sebum. Lightweight yet deeply nourishing, squalane replenishes lost lipids, repairs the skin barrier, and works seamlessly with virtually every other skincare ingredient.
A steam-distilled essential oil from the Melaleuca alternifolia plant with clinically validated antimicrobial and anti-inflammatory properties. At the correct concentration, tea tree oil is one of the most effective natural ingredients for treating acne and fungal skin conditions.
A synthetic lysine derivative that blocks multiple steps in the melanin production pathway, making it one of the most effective topical treatments for melasma, post-inflammatory hyperpigmentation, and stubborn dark spots. Well- tolerated and suitable for all skin types.
A naturally occurring humectant and keratolytic agent found in healthy skin that attracts moisture, softens keratin, and at higher concentrations gently exfoliates rough or thickened skin. An underrated workhorse for dry skin conditions, keratosis pilaris, and cracked heels.
The gold standard brightening and antioxidant ingredient. L-Ascorbic Acid, the most bioavailable form of vitamin C, neutralizes free radicals, inhibits melanin production, and stimulates collagen synthesis. Particularly effective when used in the morning to reinforce sunscreen against UV and environmental damage.
A fat-soluble antioxidant that protects skin from oxidative stress, supports barrier function, and works synergistically with vitamin C to enhance photoprotection. One of the skin's most important endogenous antioxidants.
A mineral UV filter and anti-inflammatory agent that sits on the skin surface to physically block UVA and UVB radiation. Widely used in sunscreens and recommended for sensitive, acne-prone, and rosacea-affected skin.
