Modern skin is exposed daily to numerous external and internal factors that accelerate the aging process. Urban environments, UV exposure, lack of sleep, and constant stress gradually affect its condition. As a result, the skin loses freshness, becomes less firm, develops uneven tone, and shows early signs of aging.
The eye area is especially vulnerable — the skin here is thinner, loses moisture faster, and is the first to reflect visible aging changes. Many skincare products are either too aggressive for this zone or not effective enough to deliver visible results.
Another common issue is finding the balance between efficacy and tolerability. Traditional retinoids can cause irritation, peeling, and increased sensitivity, which often leads users to abandon highly effective ingredients.
This is where the need for a modern solution arises — a product that combines high performance, gentle action, and versatility of use.
SkinTra Happiness Liquid Serum 0.3% Retinal
SkinTra Happiness Liquid Serum (30 ml) is an intensive next-generation serum formulated with a high concentration of retinal (0.3%), designed for comprehensive skin renewal and anti-aging care for both the face and eye area.
Retinal acts up to 11 times faster than classic retinol because it requires only one conversion step to become an active form of vitamin A.
Key features and formula
The serum has a lightweight oil-based texture that absorbs quickly without stickiness, thanks to its squalane base.
• 0.3% Retinal (Retinaldehyde): Stimulates collagen and elastin production, improves skin density, brightens pigmentation, and regulates sebum production.
• Squalane: Skin-identical lipid that restores the protective barrier and prevents moisture loss.
• Watermelon Seed Oil: Lightweight, non-comedogenic oil rich in antioxidants and fatty acids.
• Vitamin E: A powerful antioxidant that supports regeneration and protects against free radicals.
Who it is for
The serum is suitable for all skin types, including sensitive skin (with gradual introduction), and is especially effective for:
• wrinkles and loss of firmness
• acne, comedones, and enlarged pores
• hyperpigmentation and uneven skin tone
How to use (adaptation period)
Due to the high retinal concentration, careful introduction is essential:
• Evening use only: Apply to clean, completely dry skin
• Initial application: Mix 1 drop into your regular moisturizer
• Gradual introduction: Start 1–2 times per week, gradually increasing up to 5 times weekly depending on tolerance (no irritation or peeling)
• Eye area: Safe for use around the eyes, but requires the same gradual introduction
• SPF 50: Mandatory sunscreen use every morning during the entire period of use
Important warnings
• Shelf life: Use within 3 months after opening
• Contraindications: Not recommended during pregnancy or breastfeeding
• Compatibility: Do not combine in the same routine with acids, pure Vitamin C, or other retinoids
