Ten ingredients. Every one of them organic. Here is what the Laritelle Rejuvenating Face Serum actually contains — and what each one does.

Apricot kernel oil is one of the finest base oils for facial serums — lightweight, fast-absorbing, and rich in oleic and linoleic acids that closely match the skin's own sebum composition. This structural similarity is what allows it to penetrate efficiently rather than sitting on the surface. It is particularly beneficial for dry, sensitive, and mature skin types, providing hydration without heaviness. Its low comedogenic rating makes it suitable for mixed and combination skin alongside the other carriers in this formula.

Avocado oil is richer and heavier than apricot kernel — it is the nourishing depth in the blend. High in oleic acid, vitamins A, D, and E, and phytosterols that support skin barrier repair. It is particularly associated with improving dry, dehydrated, and compromised skin barrier function. In the context of this five-oil blend, avocado provides the skin-nourishing weight that the lighter carriers balance out — the result is a serum that feels lightweight on application but delivers the deeper nourishment that avocado's fatty acid profile provides.

Peach kernel oil is close in composition to apricot kernel — oleic and linoleic acid dominant — with a slightly silkier skin feel. It is associated with improving skin softness and evenness of tone, and is particularly beneficial for sensitive, mature, and dull skin. Its high vitamin E content contributes antioxidant protection against environmental oxidative stress. In a blend with apricot kernel and avocado, peach kernel adds the silky texture that makes the serum feel refined rather than simply oily.

Sesame seed oil has been used in Ayurvedic skincare for centuries — it contains sesamol and sesamin, two antioxidant lignans found almost exclusively in sesame, that provide exceptional antioxidant protection to both the oil blend and the skin. It also has a natural mild UV-filtering effect (not a replacement for SPF, but a contributing protective factor) and documented anti-inflammatory activity. Sesame anchors the lighter carriers in the blend and contributes to the formula's shelf stability — the same antioxidants that protect skin from oxidative stress also prevent the oil blend from oxidising prematurely.

Sweet almond oil is one of the most skin-compatible carrier oils available — it is rich in oleic acid (60-70%), linoleic acid, and vitamin E, and has been used as a skincare base for centuries. It is emollient and conditioning without being occlusive — it softens and hydrates the skin surface while maintaining breathability. In combination with the other four carriers, sweet almond contributes to the serum's smooth, conditioning skin feel and ensures the formula is suitable for a wide range of skin types including sensitive skin.

Helichrysum italicum — also called immortelle or everlasting — is considered the most potent regenerative essential oil in botanical skincare. Its unique di-ketone compounds (italidiones) found nowhere else in the plant kingdom promote cellular regeneration, support the reduction of scar tissue appearance, improve skin elasticity, and reduce the appearance of broken capillaries and bruising. It also has significant anti-inflammatory and antioxidant activity through its flavonoid and phenolic content.

Genuine Helichrysum italicum essential oil — particularly from Mediterranean sources — is among the most expensive botanical ingredients in skincare, which is why most brands that list it use it at cosmetically irrelevant concentrations. In the Laritelle formula, it is listed fifth in the essential oil group, meaning it is present at meaningful concentration alongside frankincense as the formula's regenerative core.

Frankincense essential oil's active compounds — primarily boswellic acid derivatives and monoterpenes like alpha-pinene — support skin cell regeneration, stimulate collagen production, and have significant anti-inflammatory activity through inhibition of pro-inflammatory 5-lipoxygenase pathways. At the skin level this translates to visibly firmer, more toned skin appearance with consistent use, reduced appearance of fine lines and wrinkles, and improved skin elasticity. It also has astringent properties that minimise the appearance of pores and improve overall skin texture. The rich, warm, resinous note in the serum's scent profile is primarily frankincense — the grounding depth that gives the formula its luxurious warmth.

Lavender is one of the most extensively researched essential oils in skincare. Its primary active compounds — linalool and linalyl acetate — have documented anti-inflammatory, antimicrobial, and skin-calming properties. For the face serum specifically, lavender balances sebum production (beneficial for mixed and combination skin), reduces redness and irritation, and supports the healing of blemishes and minor skin imperfections through its antimicrobial activity. Lavender also bridges the helichrysum and frankincense aromatic profile with geranium and melissa — it is the botanical note that makes the serum's scent feel complete rather than simply medicinal. This series has covered lavender extensively in the hair context — the same linalool-driven anti-inflammatory activity operates at the skin surface.

Geranium essential oil is a classic skin tonic in aromatherapy skincare — its primary compounds (geraniol, citronellol, linalool) are associated with skin tone balancing, sebum regulation, and mild astringent activity that tightens the appearance of pores and improves skin texture. It is particularly valued for its ability to support both dry and oily skin simultaneously — it regulates sebum production rather than simply stripping or suppressing it, making it appropriate for mixed and combination skin types. Geranium also has documented cicatrisant properties — supporting the fading of scars, uneven pigmentation, and marks on the skin surface — that complement the helichrysum and frankincense regenerative activity.

Melissa officinalis — lemon balm — essential oil is one of the rarest and most expensive in botanical skincare, which is why it appears infrequently in formulas despite its significant therapeutic properties. Its active compounds include citral (neral and geranial), caryophyllene, and rosmarinic acid — which together provide potent antiviral, anti-inflammatory, and antioxidant activity at the skin level. For facial skincare specifically, melissa is associated with brightening dull skin, calming reactive and sensitive skin, and providing antioxidant protection against environmental oxidative stress. Its gentle citrus-floral note adds a clean brightness to the serum's aroma that lifts the heavier frankincense and helichrysum notes.
