Product Questions

Answers to common questions about Leiba Beauty formulas, ingredients, and skincare routines.

Using Our Products

For best results, apply products in order from lightest to richest texture.

Recommended routine:

Morning
1. Hydrating Oil Cleanser
2. Vitamin C Serum
3. Moisturizer
4. Sunscreen (not included in our collection)

Evening
1. Hydrating Oil Cleanser
2. 2% BHA Skin Resurfacing Toner
3. Vitamin C Serum
4. Moisturizer

This routine helps cleanse the skin, support antioxidant protection, encourage gentle resurfacing, and maintain hydration.

Our 2% BHA Skin Resurfacing Toner contains 2% salicylic acid, along with niacinamide, azelaic acid, and glycolic acid.

Because this formula combines multiple resurfacing ingredients, most people should begin using it 2–3 times per week and increase frequency gradually as tolerated.

Individuals with more resilient skin may use it once daily, while sensitive skin types may prefer every other day.

Always monitor how your skin responds.

Yes. Our Vitamin C Serum uses 3-O Ethyl Ascorbic Acid, a stable derivative of vitamin C that is generally compatible with exfoliating acids. The toner helps clear pores and refine skin texture, while the Vitamin C serum supports antioxidant protection and skin tone balance. If your skin is sensitive, consider using the toner at night and Vitamin C in the morning.
Patch testing is recommended when introducing any new skincare product. Apply a small amount of product to a discreet area such as the inner forearm or behind the ear and monitor for 24 hours before applying it to the face. This helps identify potential sensitivities before full use.

Ingredients

Our serum uses 3-O Ethyl Ascorbic Acid, a stabilized derivative of vitamin C. Research has shown that this form of vitamin C can penetrate the skin more easily than pure ascorbic acid while remaining more stable in cosmetic formulations. Vitamin C helps support antioxidant protection, skin tone brightness, and collagen support.
Bakuchiol is a plant-derived compound extracted from Psoralea corylifolia seeds. Scientific studies have shown that bakuchiol can support skin smoothing and collagen signaling pathways in ways similar to retinol, while often being better tolerated by sensitive skin. In our moisturizer, bakuchiol helps support skin firmness, smoother texture, and overall skin renewal.

Different exfoliating acids target different layers of the skin.

  • Salicylic Acid (BHA)
  • oil-soluble
  • penetrates into pores
  • helps clear buildup

Glycolic Acid (AHA)

  • water-soluble
  • works on the surface of the skin
  • helps improve texture and brightness

Using both helps support multi-level exfoliation, addressing both pore congestion and surface texture.

Squalane is a lightweight, stable lipid derived from plant sources.

It closely resembles the natural oils produced by human skin and helps support the skin barrier without feeling heavy.

Benefits include:

  • improved moisture retention
  • skin barrier support
  • smoother texture

Because it is non-comedogenic, it is generally well tolerated by most skin types.

Skin Types

Many of our formulas include ingredients that support the skin barrier, such as:

  • squalane
  • niacinamide
  • glycerin
  • ceramide NG

However, some products contain active ingredients such as salicylic acid or glycolic acid, which may require gradual introduction.

If you have sensitive skin, begin by using exfoliating products 2–3 times per week and monitor your skin’s response.

Yes.

Our moisturizer uses a blend of lightweight emollients and humectants, including glycerin and squalane, which hydrate the skin without creating a heavy or occlusive feel.

Niacinamide also helps support balanced oil production and skin barrier function.

Many oily skin types benefit from maintaining proper hydration.

Oil cleansers are designed to dissolve oil-based impurities such as sunscreen, makeup, and excess sebum.

Our cleanser uses emulsifying ingredients that allow the oils to rinse clean with water, helping remove debris without leaving heavy residue.

When properly rinsed, oil cleansers generally do not clog pores and can be beneficial for many skin types.

Results

Skin renewal occurs in cycles that typically take approximately 4–6 weeks.

Some individuals may notice improvements in skin hydration and texture sooner, while changes related to tone or clarity may take longer.

Consistent use is important for achieving the best results.

Apply skincare from thinnest to thickest texture.

Typical order:

  1. Cleanser
  2. Toner
  3. Serum
  4. Moisturizer

This sequence helps ensure that lighter formulas absorb properly before applying richer products.

Safety

If you are pregnant or breastfeeding, it is always recommended to consult your healthcare provider before introducing new skincare products. Some individuals prefer to avoid exfoliating acids such as salicylic acid or glycolic acid during pregnancy, although topical cosmetic concentrations are generally considered low. When in doubt, consult your physician.
Some formulas include naturally derived aromatic components from botanical extracts and essential oils. These are used at levels typical for cosmetic formulations. If you have a known sensitivity to fragrance or essential oils, reviewing the full ingredient list before use is recommended.
Leiba Beauty products are manufactured in the United States in facilities that follow current Good Manufacturing Practices (cGMP). This ensures consistent quality, ingredient integrity, and controlled production standards.
